Galantamine hydrobromide extended-release capsules: recommended starting dosage is 8 mg/day in morning; increase to initial maintenance dose of 16 mg/day after a minimum of 4 weeks. Based on clinical benefit and tolerability, dosage may be increased to 24 mg/day after a minimum of 4 weeks at 16 mg/day. Conversion from galantamine hydrobromide tablets to galantamine hydrobromide extended-release capsules should occur at the same daily dosage with the last dose of galantamine hydrobromide tablets taken in evening and starting galantamine hydrobromide extended-release capsules once daily treatment the next morning. Take with food; ensure adequate fluid intake during treatment Hepatic impairment: should not exceed 16 mg/day for moderate hepatic impairment; do not use in patients with severe hepatic impairment Renal impairment: should not exceed 16 mg/day for creatinine clearance 9 to 59 mL/min; do not use in patients with creatinine clearance less than 9 mL/min.

2.1 Galantamine

Hydrobromide Extended-Release Capsules Galantamine hydrobromide extended-release capsules should be administered once daily in the morning, preferably with food. The recommended starting dosage of galantamine hydrobromide extended-release capsules is 8 mg/day. The dosage should be increased to the initial maintenance dose of 16 mg/day after a minimum of 4 weeks. A further increase to 24 mg/day should be attempted after a minimum of 4 weeks at 16 mg/day. Dosage increases should be based upon assessment of clinical benefit and tolerability of the previous dose. The dosage of galantamine hydrobromide extended-release capsules shown to be effective in a controlled clinical trial is 16 to 24 mg/day. Patients currently being treated with galantamine hydrobromide tablets can convert to galantamine hydrobromide extended-release capsules by taking their last dose of galantamine hydrobromide tablets in the evening and starting galantamine hydrobromide extended-release capsules once daily treatment the next morning. Converting from galantamine hydrobromide tablets to galantamine hydrobromide extended-release capsules should occur at the same total daily dosage. 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 hydrobromide extended-release capsules 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 hydrobromide extended-release capsules are lost, however, when the drug is discontinued.
