WebFeb 28, 2016 · Morphine, Diazepam are some drugs with very high First pass effect, so most of the orally taken drugs are metabolized and hence are of no use given orally. As IV route means the drug enters systemic circulation directly, no drug enters the liver. So there is no first pass effect in the IV route drug medication. 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. WebMetabolites have 25% to 33% of diazepam’s anticonvulsant activity. Because of an extensive first pass effect, oral systemic availability is only 1% to 3%. Drugs, such as cimetidine, that inhibit hepatic microsomal enzyme activity will prolong the serum half-lives of diazepam and nordiazepam. how to see where ups truck is on its route
