Drug Interactions between Belviq and DurAct

ADJUST DOSE: In-vivo studies have demonstrated that the absorption of bromfenac is greatly reduced if the drug is taken within three and one-half hours following a high fat meal. The concomitant administration of a high fat meal has led to a 75% reduction in peak plasma concentrations and a 60% reduction in total area under the curve. The mechanism has not been described.

MANAGEMENT: An increased dosage of bromfenac (from 25 to 50 mg) may be needed if a high fat meal is consumed. The clinician may want to warn the patient about subtherapeutic analgesic effects if high fat meals are regularly consumed.

Food does not appear to significantly affect the absorption and oral bioavailability of lurasidone. In twelve adult volunteers (6 men and 6 women), administration of a single 10 mg oral dose of lorcaserin following a high-fat (approximately 50% of total caloric content of the meal) and high-calorie (approximately 800 to 1000 calories) meal resulted in less than 10% increases in lorcaserin peak plasma concentration (Cmax) and systemic exposure (AUC) compared to administration in the fasted state. The time to reach peak concentration (Tmax) was delayed by approximately 1 hour in the fed state. Lorcaserin may be administered with or without food.
