The clinical program for methylphenidate hydrochloride extended-release capsules consisted of 6 studies: 2 controlled clinical studies conducted in children with ADHD aged 6 to 12 years and 4 clinical pharmacology studies conducted in healthy adult volunteers. These studies included a total of 256 subjects; 195 children with ADHD and 61 healthy adult volunteers. The subjects received methylphenidate hydrochloride extended-release capsules in doses of 10 to 40 mg per day. Safety of methylphenidate hydrochloride extended-release capsule was assessed by evaluating frequency and nature of adverse events, routine laboratory tests, vital signs, and body weight. A placebo-controlled, double-blind, parallel-group study was conducted to evaluate the efficacy and safety of methylphenidate hydrochloride extended-release capsules in children with ADHD aged 6 to 12 years. All subjects received methylphenidate hydrochloride extended-release capsules for up to 4 weeks, and had their dose optimally adjusted, prior to entering the double-blind phase of the trial. In the 2-week double-blind treatment phase of this study, patients received either placebo or methylphenidate hydrochloride extended-release capsules at their individually-titrated dose (range 10 to 40 mg). Adverse reactions with an incidence greater than 5% during the initial 4-week single-blind methylphenidate hydrochloride extended-release capsule titration period of this study were headache, insomnia, upper abdominal pain, appetite decreased, and anorexia. Adverse reactions with an incidence greater than 2% among methylphenidate hydrochloride extended-release capsule-treated subjects, during the 2-week double blind phase of the clinical study, are shown in Table 2. Table 2: Adverse Reactions in Greater Than 2% Methylphenidate Hydrochloride Extended-release Capsules-Treated Subjects in the 2-Week Double-Blind Phase Preferred Term Methylphenidate Hydrochloride Extended-release Capsules N = 65 N (%) Placebo N = 71 N (%) Anorexia 2 (3.1) 0 (0.0) Insomnia 2 (3.1) 0 (0.0) Adverse Events Associated With Discontinuation of Treatment In the 2-week double-blind treatment phase of a placebo-controlled parallel-group study in children with ADHD, one methylphenidate hydrochloride extended-release capsules-treated subject (1/65, 1.5%) discontinued due to an adverse event (depressed mood). In the single-blind titration period of this study, subjects received methylphenidate hydrochloride extended-release capsules for up to 4 weeks. During this period a total of 6 subjects (6/161, 3.7%) discontinued due to adverse events. The adverse events leading to discontinuation were anger (2 patients), hypomania, anxiety, depressed mood, fatigue, migraine and lethargy. 6.2 Postmarketing Experience The following adverse reactions have been identified during the post approval use of methylphenidate products. Because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency reliably or to establish a causal relationship to drug exposure.

2 DOSAGE AND ADMINISTRATION • Administer orally once daily in the morning ( 2.2 ). • Capsules may be swallowed whole, or opened and the entire contents sprinkled on applesauce ( 2.2 ). • Should not be crushed, chewed, or divided ( 2.2 ). • Patients new to methylphenidate: Start at 20 mg daily, titrating the dose weekly in 10 mg increments. Doses above 60 mg daily are not recommended ( 2.3 ). • For patients currently using methylphenidate hydrochloride or methylphenidate hydrochloride extended release tablets: Dosage is based on current dose regimen ( 2.4 ). • If switching from other methylphenidate products, discontinue treatment and titrate with methylphenidate hydrochloride extended release capsules ( 2.4 ). 2.1 Pretreatment Screening Prior to initiating treatment with central nervous system (CNS) stimulants, including methylphenidate hydrochloride extended-release capsules, assess for the presence of cardiac disease (i.e., perform a careful history including family history of sudden death or ventricular arrhythmia, and physical examination) [see Warnings and Precautions ( 5.2 )] . Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy. Maintain careful prescription records, educate patients about abuse, monitor for signs of abuse and overdose, and periodically reevaluate the need for methylphenidate hydrochloride extended-release capsule use [see Boxed Warning, Warnings and Precautions ( 5.1 ), Drug Abuse and Dependence ( 9.2 , 9.3 )]. 2.2 General Dosing Information The recommended starting dose for methylphenidate hydrochloride extended-release capsules is 20 mg once daily. Increase dosage gradually, in increments of 10 mg weekly. Daily dosage above 60 mg is not recommended. When a lower initial dose is appropriate, patients may begin treatment with 10 mg. Administer methylphenidate hydrochloride extended-release capsules orally once daily in the morning. Methylphenidate hydrochloride extended-release capsules may be swallowed as whole capsule or may be administered by sprinkling the capsule contents on a small amount of applesauce (see specific instructions below). Methylphenidate hydrochloride extended-release capsules and/or their contents should not be crushed, chewed, or divided. The capsules may be carefully opened and the beads sprinkled over a spoonful of applesauce. The applesauce should not be warm because it could affect the modified release properties of this formulation. The mixture of drug and applesauce should be consumed immediately in its entirety. The drug and applesauce mixture should not be stored for future use. Pharmacological treatment of ADHD may be needed for extended periods. Periodically reevaluate the long-term use of methylphenidate hydrochloride and methylphenidate hydrochloride extended-release tablets, and adjust dosage as needed. 2.3 Patients Currently Using Methylphenidate Hydrochloride or Methylphenidate Hydrochloride Extended-release Tablets The recommended dose of methylphenidate hydrochloride extended-release capsules for patients currently taking methylphenidate hydrochloride tablets twice daily or methylphenidate hydrochloride extended-release tablets is provided below. Table 1: Recommended Dose Conversion From Methylphenidate Hydrochloride or Methylphenidate Hydrochloride Extended-release Tablets Previous Methylphenidate Hydrochloride or Methylphenidate Hydrochloride Extended-release Tablets Dose Recommended Methylphenidate Hydrochloride Extended-release Capsule Dose 5 mg methylphenidate hydrochloride tablets twice daily 10 mg once daily 10 mg methylphenidate hydrochloride tablets twice daily or 20 mg methylphenidate hydrochloride extended-release tablets 20 mg once daily 15 mg methylphenidate hydrochloride tablets twice daily 30 mg once daily 20 mg methylphenidate hydrochloride tablets twice daily or 40 mg methylphenidate hydrochloride extended-release tablets 40 mg once daily 30 mg methylphenidate hydrochloride tablets twice daily or 60 mg methylphenidate hydrochloride extended-release tablets 60 mg once daily 2.4 Switching From Other Methylphenidate Products If switching from other methylphenidate products, discontinue that treatment, and titrate with methylphenidate hydrochloride extended-release capsules using the titration schedule. Do not substitute for other methylphenidate products on a milligram-per-milligram basis, because different methylphenidate base compositions and differing pharmacokinetic profiles [see Description ( 11 ), Clinical Pharmacology ( 12.3 )] . Clinical judgment should be used when selecting the starting dose. Daily dosage above 60 mg is not recommended. 2.5 Dose Reduction and Discontinuation If paradoxical worsening of symptoms or other adverse reactions occur, reduce the dosage, or, if necessary, discontinue methylphenidate hydrochloride extended-release capsules. If improvement is not observed after appropriate dosage adjustment over a one-month period, the drug should be discontinued.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Methylphenidate hydrochloride is a central nervous system (CNS) stimulant. The mode of therapeutic action in ADHD is not known. 12.2 Pharmacodynamics Methylphenidate is a racemic mixture comprised of the d- and l-threo enantiomers. The d‑threo enantiomer is more pharmacologically active than the l-threo enantiomer. Methylphenidate is thought to block the reuptake of norepinephrine and dopamine into the presynaptic neuron and increase the release of these monoamines into the extraneuronal space. Cardiac Electrophysiology A formal QT study has not been conducted in patients taking methylphenidate hydrochloride extended-release capsules. The effect of dexmethylphenidate, the pharmacologically active d -enantiomer of methylphenidate hydrochloride, on the QT interval was evaluated in a double-blind, placebo- and open-label active (moxifloxacin)-controlled study following single doses of dexmethylphenidate XR 40 mg (maximum recommended adult total daily dosage) in 75 healthy volunteers. ECGs were collected up to 12 hours postdose. Frederica’s method for heart rate correction was employed to derive the corrected QT interval (QTcF). The maximum mean prolongation of QTcF intervals was less than 5 ms, and the upper limit of the 90% confidence interval (CI) was below 10 ms for all time matched comparisons versus placebo. This was below the threshold of clinical concern and there was no evident-exposure response relationship. 12.3 Pharmacokinetics Methylphenidate hydrochloride extended-release capsule produces a bi-modal plasma concentration-time profile (i.e., 2 distinct peaks approximately 4 hours apart) when administered orally to children diagnosed with ADHD and healthy adults. No accumulation of methylphenidate is expected following multiple once daily oral dosing with methylphenidate hydrochloride extended-release capsules, however, there is a slight upward trend in the methylphenidate area under the curve (AUC) and peak plasma concentrations (C max1 and C max2 ) after oral administration of methylphenidate hydrochloride extended-release capsules 20 mg and 40 mg capsules to adults. Absorption The absolute oral bioavailability of methylphenidate in children was 22 ± 8% for d-methylphenidate and 5 ± 3% for l-methylphenidate. The relative bioavailability of methylphenidate hydrochloride extended-release capsules given once daily is comparable to the same total dose of methylphenidate hydrochloride tablets given in 2 doses 4 hours apart in both children and adults. The initial rate of absorption for methylphenidate hydrochloride extended-release capsule is similar to that of methylphenidate hydrochloride tablets as shown by the similar rate parameters between the 2 formulations, i.e., initial lag time (T lag ), first peak concentration (C max1 ), and time to the first peak (T max1 ), which is reached in 1 to 3 hours. The mean time to the interpeak minimum (T minip ), and time to the second peak (T max2 ) are also similar for methylphenidate hydrochloride extended-release capsules given once daily and methylphenidate hydrochloride tablets given in 2 doses 4 hours apart (see Figure 1 and Table 1), although the ranges observed are greater for methylphenidate hydrochloride extended-release capsules. Methylphenidate hydrochloride extended-release capsules given once daily exhibits a lower second peak concentration (C max2 ), higher interpeak minimum concentrations (C minip ), and less peak and trough fluctuations than methylphenidate hydrochloride tablets given in 2 doses given 4 hours apart. This is due to an earlier onset and more prolonged absorption from the delayed-release beads (see Figure 1 and Table 4).

When methylphenidate hydrochloride extended-release capsule was administered with a high fat breakfast to adults, methylphenidate hydrochloride extended-release capsule had a longer lag time until absorption began and variable delays in the time until the first peak concentration, the time until the interpeak minimum, and the time until the second peak. The first peak concentration and the extent of absorption were unchanged after food relative to the fasting state, although the second peak was approximately 25% lower. The effect of a high fat lunch was not examined. There were no differences in the pharmacokinetics of methylphenidate hydrochloride extended-release capsule when administered with applesauce, compared to administration in the fasting condition. There is no evidence of dose dumping in the presence or absence of food. Effect of Alcohol An in vitro study was conducted to explore the effect of alcohol on the release characteristics of methylphenidate from the methylphenidate hydrochloride extended-release 40 mg capsule dosage form. At an alcohol concentration of 40% there was a 98% release of methylphenidate in the first hour. The results with the 40 mg capsule are considered to be representative of the other available capsule strengths. Distribution Binding to plasma proteins is low (10% to 33%). The volume of distribution was 2.65 ± 1.11 L/kg for d-methylphenidate and 1.80 ± 0.91 L/kg for l-methylphenidate. Elimination The systemic clearance is 0.40 ± 0.12 L/h/kg for d-methylphenidate and 0.73 ± 0.28 L/h/kg for l-methylphenidate. In studies with methylphenidate hydrochloride extended-release capsules and methylphenidate hydrochloride tablets in adults, methylphenidate from methylphenidate hydrochloride tablets is eliminated from plasma with an average half-life of about 3.5 hours, (range 1.3 to 7.7 hours). In children the average half-life is about 2.5 hours, with a range of about 1.5 to 5.0 hours. The rapid half-life in both children and adults may result in un-measurable concentrations between the morning and mid-day doses with methylphenidate hydrochloride tablets. No accumulation of methylphenidate is expected following multiple once a day oral dosing with methylphenidate hydrochloride extended-release capsules. The half-life of ritalinic acid is about 3 to 4 hours. Metabolism The absolute oral bioavailability of methylphenidate in children was 22 ± 8% for d-methylphenidate and 5 ± 3% for l-methylphenidate, suggesting pronounced presystemic metabolism. Biotransformation of methylphenidate by the carboxylesterase CES1A1 is rapid and extensive leading to the main, de-esterified metabolite α-phenyl-2-piperidine acetic acid (ritalinic acid), which has little or no pharmacologic activity. Only small amounts of hydroxylated metabolites (e.g., hydroxymethylphenidate and hydroxyritalinic acid) are detectable in plasma. Therapeutic activity is principally due to the parent compound. Excretion After oral administration of an immediate release formulation of methylphenidate, 78% to 97% of the dose is excreted in the urine and 1% to 3% in the feces in the form of metabolites within 48 to 96 hours. Only small quantities (less than 1%) of unchanged methylphenidate appear in the urine. Most of the dose is excreted in the urine as ritalinic acid (60% to 86%), the remainder being accounted for by minor metabolite. Studies in Specific Populations Male and Female Patients There were no apparent gender differences in the pharmacokinetics of methylphenidate between healthy male and female adults when administered methylphenidate hydrochloride extended-release capsules. Racial or Ethnic Groups There is insufficient experience with the use of methylphenidate hydrochloride extended-release capsules to detect ethnic variations in pharmacokinetics. Pediatric Patients The pharmacokinetics of methylphenidate hydrochloride extended-release capsules was examined in 18 children with ADHD between 7 and 12 years of age. Fifteen of these children were between 10 and 12 years of age. The time until the between peak minimum, and the time until the second peak were delayed and more variable in children compared to adults. After a 20-mg dose of methylphenidate hydrochloride extended-release capsule, concentrations in children were approximately twice the concentrations observed in 18 to 35 year old adults. This higher exposure is almost completely due to the smaller body size and total volume of distribution in children, as apparent clearance normalized to body weight is independent of age. Patients with Renal Impairment Methylphenidate hydrochloride extended-release capsules has not been studied in renally-impaired patients. Renal impairment is expected to have minimal effect on the pharmacokinetics of methylphenidate since less than 1% of a radiolabeled dose is excreted in the urine as unchanged compound, and the major metabolite (ritalinic acid), has little or no pharmacologic activity. Patients with Hepatic Impairment Methylphenidate hydrochloride extended-release capsule has not been studied in patients with hepatic impairment. Hepatic impairment is expected to have minimal effect on the pharmacokinetics of methylphenidate since it is metabolized primarily to ritalinic acid by nonmicrosomal hydrolytic esterases that are widely distributed throughout the body.

The relative bioavailability of methylphenidate hydrochloride extended-release capsules given once daily is comparable to the same total dose of methylphenidate hydrochloride tablets given in 2 doses 4 hours apart in both children and adults. The initial rate of absorption for methylphenidate hydrochloride extended-release capsule is similar to that of methylphenidate hydrochloride tablets as shown by the similar rate parameters between the 2 formulations, i.e., initial lag time (T lag ), first peak concentration (C max1 ), and time to the first peak (T max1 ), which is reached in 1 to 3 hours. The mean time to the interpeak minimum (T minip ), and time to the second peak (T max2 ) are also similar for methylphenidate hydrochloride extended-release capsules given once daily and methylphenidate hydrochloride tablets given in 2 doses 4 hours apart (see Figure 1 and Table 1), although the ranges observed are greater for methylphenidate hydrochloride extended-release capsules. Methylphenidate hydrochloride extended-release capsules given once daily exhibits a lower second peak concentration (C max2 ), higher interpeak minimum concentrations (C minip ), and less peak and trough fluctuations than methylphenidate hydrochloride tablets given in 2 doses given 4 hours apart. This is due to an earlier onset and more prolonged absorption from the delayed-release beads (see Figure 1 and Table 4).

When methylphenidate hydrochloride extended-release capsule was administered with a high fat breakfast to adults, methylphenidate hydrochloride extended-release capsule had a longer lag time until absorption began and variable delays in the time until the first peak concentration, the time until the interpeak minimum, and the time until the second peak. The first peak concentration and the extent of absorption were unchanged after food relative to the fasting state, although the second peak was approximately 25% lower. The effect of a high fat lunch was not examined. There were no differences in the pharmacokinetics of methylphenidate hydrochloride extended-release capsule when administered with applesauce, compared to administration in the fasting condition. There is no evidence of dose dumping in the presence or absence of food. Effect of Alcohol An in vitro study was conducted to explore the effect of alcohol on the release characteristics of methylphenidate from the methylphenidate hydrochloride extended-release 40 mg capsule dosage form. At an alcohol concentration of 40% there was a 98% release of methylphenidate in the first hour. The results with the 40 mg capsule are considered to be representative of the other available capsule strengths. Distribution Binding to plasma proteins is low (10% to 33%). The volume of distribution was 2.65 ± 1.11 L/kg for d-methylphenidate and 1.80 ± 0.91 L/kg for l-methylphenidate. Elimination The systemic clearance is 0.40 ± 0.12 L/h/kg for d-methylphenidate and 0.73 ± 0.28 L/h/kg for l-methylphenidate. In studies with methylphenidate hydrochloride extended-release capsules and methylphenidate hydrochloride tablets in adults, methylphenidate from methylphenidate hydrochloride tablets is eliminated from plasma with an average half-life of about 3.5 hours, (range 1.3 to 7.7 hours). In children the average half-life is about 2.5 hours, with a range of about 1.5 to 5.0 hours. The rapid half-life in both children and adults may result in un-measurable concentrations between the morning and mid-day doses with methylphenidate hydrochloride tablets. No accumulation of methylphenidate is expected following multiple once a day oral dosing with methylphenidate hydrochloride extended-release capsules. The half-life of ritalinic acid is about 3 to 4 hours. Metabolism The absolute oral bioavailability of methylphenidate in children was 22 ± 8% for d-methylphenidate and 5 ± 3% for l-methylphenidate, suggesting pronounced presystemic metabolism. Biotransformation of methylphenidate by the carboxylesterase CES1A1 is rapid and extensive leading to the main, de-esterified metabolite α-phenyl-2-piperidine acetic acid (ritalinic acid), which has little or no pharmacologic activity. Only small amounts of hydroxylated metabolites (e.g., hydroxymethylphenidate and hydroxyritalinic acid) are detectable in plasma. Therapeutic activity is principally due to the parent compound. Excretion After oral administration of an immediate release formulation of methylphenidate, 78% to 97% of the dose is excreted in the urine and 1% to 3% in the feces in the form of metabolites within 48 to 96 hours. Only small quantities (less than 1%) of unchanged methylphenidate appear in the urine. Most of the dose is excreted in the urine as ritalinic acid (60% to 86%), the remainder being accounted for by minor metabolite. Studies in Specific Populations Male and Female Patients There were no apparent gender differences in the pharmacokinetics of methylphenidate between healthy male and female adults when administered methylphenidate hydrochloride extended-release capsules. Racial or Ethnic Groups There is insufficient experience with the use of methylphenidate hydrochloride extended-release capsules to detect ethnic variations in pharmacokinetics. Pediatric Patients The pharmacokinetics of methylphenidate hydrochloride extended-release capsules was examined in 18 children with ADHD between 7 and 12 years of age. Fifteen of these children were between 10 and 12 years of age. The time until the between peak minimum, and the time until the second peak were delayed and more variable in children compared to adults. After a 20-mg dose of methylphenidate hydrochloride extended-release capsule, concentrations in children were approximately twice the concentrations observed in 18 to 35 year old adults. This higher exposure is almost completely due to the smaller body size and total volume of distribution in children, as apparent clearance normalized to body weight is independent of age. Patients with Renal Impairment Methylphenidate hydrochloride extended-release capsules has not been studied in renally-impaired patients. Renal impairment is expected to have minimal effect on the pharmacokinetics of methylphenidate since less than 1% of a radiolabeled dose is excreted in the urine as unchanged compound, and the major metabolite (ritalinic acid), has little or no pharmacologic activity. Patients with Hepatic Impairment Methylphenidate hydrochloride extended-release capsule has not been studied in patients with hepatic impairment. Hepatic impairment is expected to have minimal effect on the pharmacokinetics of methylphenidate since it is metabolized primarily to ritalinic acid by nonmicrosomal hydrolytic esterases that are widely distributed throughout the body.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis In a lifetime carcinogenicity study carried out in B6C3F1 mice, methylphenidate caused an increase in hepatocellular adenomas, and in males only, an increase in hepatoblastomas at a daily dose of approximately 60 mg/kg/day. This dose is approximately 2 times the MRHD of 60 mg/day given to children on a mg/m 2 basis. Hepatoblastoma is a relatively rare rodent malignant tumor type. There was no increase in total malignant hepatic tumors. The mouse strain used is sensitive to the development of hepatic tumors, and the significance of these results to humans is unknown. Methylphenidate did not cause any increase in tumors in a lifetime carcinogenicity study carried out in F344 rats; the highest dose used was approximately 45 mg/kg/day, which is approximately 4 times the MRHD (children) on a mg/m 2 basis. In a 24-week carcinogenicity study in the transgenic mouse strain p53+/-, which is sensitive to genotoxic carcinogens, there was no evidence of carcinogenicity. Male and female mice were fed diets containing the same concentration of methylphenidate as in the lifetime carcinogenicity study; the high-dose groups were exposed to 60 to 74 mg/kg/day of methylphenidate. Mutagenesis Methylphenidate was not mutagenic in the in vitro Ames reverse mutation assay, in the in vitro mouse lymphoma cell forward mutation assay, or in the in vitro chromosomal aberration assay using human lymphocytes. Sister chromatid exchanges and chromosome aberrations were increased, indicative of a weak clastogenic response, in an in vitro assay in cultured Chinese Hamster Ovary (CHO) cells. Methylphenidate was negative in vivo in males and females in the mouse bone marrow micronucleus assay. Impairment of Fertility Methylphenidate did not impair fertility in male or female mice that were fed diets containing the drug in an 18-week continuous breeding study. The study was conducted at doses up to 160 mg/kg/day, approximately 10 times the maximum recommended dose of 60 mg/day given to adolescents on a mg/m 2 basis.

14 CLINICAL STUDIES 14.1 Children and Adolescents Methylphenidate hydrochloride extended-release capsule was evaluated in a randomized, double-blind, placebo-controlled, parallel group clinical study in which 134 children, ages 6 to 12, with DSM-IV diagnoses of ADHD received a single morning dose of methylphenidate hydrochloride extended-release capsules in the range of 10 to 40 mg/day, or placebo, for up to 2 weeks. The doses used were the optimal doses established in a previous individual dose titration phase. In that titration phase, 53 of 164 patients (32%) started on a daily dose of 10 mg and 111 of 164 patients (68%) started on a daily dose of 20 mg or higher. The patient’s regular schoolteacher completed the Conners ADHD/DSM-IV Scale for Teachers (CADS-T) at baseline and the end of each week. The CADS-T assesses symptoms of hyperactivity and inattention. The change from baseline of the (CADS-T) scores during the last week of treatment was analyzed as the primary efficacy parameter. Patients treated with methylphenidate hydrochloride extended-release capsules showed a statistically significant improvement in symptom scores from baseline [Mean (final score - baseline) = -10.7 points] over patients who received placebo [Mean (final score - baseline) = +2.8 points]. The lower the final score on the CADS-T scale from baseline, the less severe the disease is. This demonstrates that a single morning dose of methylphenidate hydrochloride extended-release capsules exerts a treatment effect in ADHD. Figure-2

8.5 Geriatric Use Methylphenidate hydrochloride extended-release capsules have not been studied in the geriatric population.

8.4 Pediatric Use The safety and effectiveness of methylphenidate hydrochloride extended-release capsules for the treatment of ADHD have been established in pediatric patients 6 to 12 years. The safety and effectiveness of methylphenidate hydrochloride extended-release capsules in pediatric patients less than 6 years have not been established. The long-term efficacy of methylphenidate hydrochloride extended-release capsules in pediatric patients has not been established. Long-Term Suppression of Growth Growth should be monitored during treatment with stimulants, including methylphenidate hydrochloride extended-release capsules. Pediatric patients who are not growing or gaining weight as expected may need to have their treatment interrupted [see Warnings and Precautions ( 5.7 )] . Juvenile Animal Toxicity Data Rats treated with methylphenidate early in the postnatal period through sexual maturation demonstrated a decrease in spontaneous locomotor activity in adulthood. A deficit in acquisition of a specific learning task was observed in females only. The doses at which these findings were observed are at least 4 times the MRHD of 60 mg/day given to children on a mg/m 2 basis. In a study conducted in young rats, methylphenidate was administered orally at doses of up to 100 mg/kg/day for 9 weeks, starting early in the postnatal period (postnatal Day 7) and continuing through sexual maturity (postnatal Week 10). When these animals were tested as adults (postnatal Weeks 13 to 14), decreased spontaneous locomotor activity was observed in males and females previously treated with 50 mg/kg/day (approximately 4 times the MRHD of 60 mg/day given to children on a mg/m 2 basis) or greater, and a deficit in the acquisition of a specific learning task was seen in females exposed to the highest dose (8 times the MRHD given to children on a mg/m 2 basis). The no effect level for juvenile neurobehavioral development in rats was 5 mg/kg/day (approximately 0.5 times the MRHD given to children on a mg/m 2 basis). The clinical significance of the long-term behavioral effects observed in rats is unknown.

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADHD medications, including methylphenidate hydrochloride extended-release capsules during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy registry for ADHD medications at 1-866-961-2388 or visit https://womensmentalhealth.org/adhd-medications/. Risk Summary Published studies and postmarketing reports on methylphenidate use during pregnancy have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. There may be risks to the fetus associated with the use of CNS stimulants use during pregnancy (see Clinical Considerations) . No effects on morphological development were observed in embryo-fetal development studies with oral administration of methylphenidate to pregnant rats and rabbits during organogenesis at doses up to 10 and 15 times, respectively, the maximum recommended human dose (MRHD) of 60 mg/day given to adolescents on a mg/m 2 basis. However, spina bifida was observed in rabbits at a dose 52 times the MRHD given to adolescents. A decrease in pup body weight was observed in a pre- and post-natal development study with oral administration of methylphenidate to rats throughout pregnancy and lactation at doses 6 times the MRHD given to adolescents (see Data) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions CNS stimulants, such as methylphenidate hydrochloride extended-release capsules, can cause vasoconstriction and thereby decrease placental perfusion. No fetal and/or neonatal adverse reactions have been reported with the use of therapeutic doses of methylphenidate during pregnancy; however, premature delivery and low birth weight infants have been reported in amphetamine-dependent mothers. Data Animal Data In embryo-fetal development studies conducted in rats and rabbits, methylphenidate was administered orally at doses of up to 75 and 200 mg/kg/day, respectively, during the period of organogenesis. Malformations (increased incidence of fetal spina bifida) were observed in rabbits at the highest dose, which is approximately 52 times the MRHD of 60 mg/day given to adolescents on a mg/m 2 basis. The no effect level for embryo-fetal development in rabbits was 60 mg/kg/day (15 times the MRHD given to adolescents on a mg/m 2 basis). There was no evidence of morphological development effects in rats, although increased incidences of fetal skeletal variations were seen at the highest dose level (10 times the MRHD of 60 mg/day given to adolescents on a mg/m 2 basis), which was also maternally toxic. The no effect level for embryo-fetal development in rats was 25 mg/kg/day (3 times the MRHD on a mg/m 2 basis). When methylphenidate was administered to rats throughout pregnancy and lactation at doses of up to 45 mg/kg/day, offspring body weight gain was decreased at the highest dose (6 times the MRHD of 60 mg/day given to adolescents on a mg/m 2 basis), but no other effects on postnatal development were observed. The no effect level for pre- and postnatal development in rats was 15 mg/kg/day (~2 times the MRHD given to adolescents on a mg/m 2 basis).

The no effect level for pre- and postnatal development in rats was 15 mg/kg/day (~2 times the MRHD given to adolescents on a mg/m 2 basis). 8.2 Lactation Risk Summary Limited published literature, based on milk sampling from seven mothers reports that methylphenidate is present in human milk, which resulted in infant doses of 0.16% to 0.7% of the maternal weight-adjusted dosage and a milk/plasma ratio ranging between 1.1 and 2.7. There are no reports of adverse effects on the breastfed infant and no effects on milk production. Long-term neurodevelopmental effects on infants from stimulant exposure are unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for methylphenidate hydrochloride extended-release capsules and any potential adverse effects on the breastfed infant from methylphenidate hydrochloride extended-release capsules or from the underlying maternal condition. Clinical Considerations Monitor breastfeeding infants for adverse reactions, such as agitation, insomnia, anorexia, and reduced weight gain. 8.4 Pediatric Use The safety and effectiveness of methylphenidate hydrochloride extended-release capsules for the treatment of ADHD have been established in pediatric patients 6 to 12 years. The safety and effectiveness of methylphenidate hydrochloride extended-release capsules in pediatric patients less than 6 years have not been established. The long-term efficacy of methylphenidate hydrochloride extended-release capsules in pediatric patients has not been established. Long-Term Suppression of Growth Growth should be monitored during treatment with stimulants, including methylphenidate hydrochloride extended-release capsules. Pediatric patients who are not growing or gaining weight as expected may need to have their treatment interrupted [see Warnings and Precautions ( 5.7 )] . Juvenile Animal Toxicity Data Rats treated with methylphenidate early in the postnatal period through sexual maturation demonstrated a decrease in spontaneous locomotor activity in adulthood. A deficit in acquisition of a specific learning task was observed in females only. The doses at which these findings were observed are at least 4 times the MRHD of 60 mg/day given to children on a mg/m 2 basis. In a study conducted in young rats, methylphenidate was administered orally at doses of up to 100 mg/kg/day for 9 weeks, starting early in the postnatal period (postnatal Day 7) and continuing through sexual maturity (postnatal Week 10). When these animals were tested as adults (postnatal Weeks 13 to 14), decreased spontaneous locomotor activity was observed in males and females previously treated with 50 mg/kg/day (approximately 4 times the MRHD of 60 mg/day given to children on a mg/m 2 basis) or greater, and a deficit in the acquisition of a specific learning task was seen in females exposed to the highest dose (8 times the MRHD given to children on a mg/m 2 basis). The no effect level for juvenile neurobehavioral development in rats was 5 mg/kg/day (approximately 0.5 times the MRHD given to children on a mg/m 2 basis). The clinical significance of the long-term behavioral effects observed in rats is unknown. 8.5 Geriatric Use Methylphenidate hydrochloride extended-release capsules have not been studied in the geriatric population.
