First Pass Effect Stroke
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. WebBackground The ‘first pass effect’ (FPE), which was originally described with stent retrievers, designates a (near-)complete revascularization obtained after a single device pass with no rescue therapy, and is associated with improved clinical outcome and decreased mortality. Objective We report the rate and benefits of FPE in the Aspiration … he walked on water
