First pass effect of diazepam
WebDiazepam produces less sedation in cigarette smokers, and higher doses may be required for the same sedative or anxiolytic effect. Owing in part to its continued widespread use, several unusual adverse effects of diazepam continue to be reported. WebFirst-pass effect is the loss of potency of a drug that results when it undergoes metabolism in both the liver and the gut wall prior to reaching systemic circulation. Since diazepam, a benzodiazepine, is metabolized in both these sites, it experiences a significant first-pass effect. This also results in higher variability in bioavailability.
