2.2 Galantamine Immediate-Release Tablets

The dosage of galantamine tablets shown to be effective in controlled clinical trials is 16 to 32 mg/day given as twice daily dosing. As the dosage of 32 mg/day is less well tolerated than lower dosages and does not provide increased effectiveness, the recommended dosage range is 16 to 24 mg/day given twice daily. The dosage of 24 mg/day did not provide a statistically significant greater clinical benefit than 16 mg/day. It is possible, however, that a daily dosage of 24 mg of galantamine tablets might provide additional benefit for some patients.

The recommended starting dosage of galantamine tablets is 4 mg twice a day (8 mg/day). The dosage should be increased to the initial maintenance dosage of 8 mg twice a day (16 mg/day) after a minimum of 4 weeks. A further increase to 12 mg twice a day (24 mg/day) should be attempted after a minimum of 4 weeks at 8 mg twice a day (16 mg/day).

Dosage increases should be based upon assessment of clinical benefit and tolerability of the previous dose.

Galantamine tablets should be administered twice a day, preferably with morning and evening meals.

Patients and caregivers should be advised to ensure adequate fluid intake during treatment. If therapy has been interrupted for more than three days, the patient should be restarted at the lowest dosage and the dosage escalated to the current dose.

The abrupt withdrawal of galantamine tablets in those patients who had been receiving dosages in the effective range was not associated with an increased frequency of adverse events in comparison with those continuing to receive the same dosages of that drug. The beneficial effects of galantamine tablets are lost, however, when the drug is discontinued.
2.3 Dosage in Patients with Hepatic Impairment
In patients with moderate hepatic impairment (Child-Pugh score of 7 to 9), the dosage should generally not exceed 16 mg/day. The use of galantamine tablets in patients with severe hepatic impairment (Child-Pugh score of 10 to 15) is not recommended [see Clinical Pharmacology (12.3)].
2.4 Dosage in Patients with Renal Impairment
In patients with creatinine clearance of 9 to 59 mL/min, the dosage should generally not exceed 16 mg/day. In patients with creatinine clearance less than 9 mL/min, the use of and galantamine tablets is not recommended [see Clinical Pharmacology (12.3)].

2.1 Asthma
Montelukast sodium should be taken once daily in the evening. The following doses are recommended:
For adults and adolescents 15 years of age and older: one 10 mg tablet.
For pediatric patients 6 to 14 years of age: one 5 mg chewable tablet.
For pediatric patients 2 to 5 years of age: one 4 mg chewable tablet
Safety and effectiveness in pediatric patients less than 12 months of age with asthma have not been established.
There have been no clinical trials in patients with asthma to evaluate the relative efficacy of morning versus evening dosing. The pharmacokinetics of montelukast are similar whether dosed in the morning or evening. Efficacy has been demonstrated for asthma when montelukast was administered in the evening without regard to time of food ingestion.
2.2 Exercise-Induced Bronchoconstriction (EIB) in Patients 15 Years of Age and Older
For prevention of EIB, a single 10 mg dose of montelukast should be taken at least 2 hours before exercise.
An additional dose of montelukast should not be taken within 24 hours of a previous dose. Patients already taking montelukast sodium daily for another indication (including chronic asthma) should not take an additional dose to prevent EIB. All patients should have available for rescue a short-acting β-agonist. Safety and effectiveness in patients younger than 15 years of age have not been established. Daily administration of montelukast sodium for the chronic treatment of asthma has not been established to prevent acute episodes of EIB.
Pediatric use information for patients ages 6 to 14 years of age for acute prevention of exercise-induced bronchoconstriction (EIB) is approved for Merck Sharp & Dohme Corp’s montelukast tablet products. However, due to Merck Sharp & Dohme Corp’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.
2.3 Allergic Rhinitis
For allergic rhinitis, montelukast sodium should be taken once daily.

The following doses for the treatment of symptoms of seasonal allergic rhinitis are recommended:
For adults and adolescents 15 years of age and older: one 10 mg tablet.
