diclegis half life
Pharmacology and Pharmacokinetics. The mechanism of action of Diclegis is unknown.1. Peak plasma concentrations of the doxylamine component occur in 7.5 hours, and the pyridoxine component, 5.5 hours. Elimination half-life is 12.5 hours for the doxylamine component, and in 0.5 hours for the pyridoxine component. Steady-state concentrations of doxylamine are reached within 24 to 48 hours. Pyridoxine does not reach steady-state concentrations due to its short half-life.1.
