Induction Inhibition and Receptor Interactions

erate-to-potent inhibitors of CYP3A4, it is not surprising that drug toxicity of CYP3A4 substrates due to inhibition of CYP3A4 is relatively common. CYP3A4 also is sensitive to enzyme induction, and a number of drugs are known to be CYP3A4 inducers. CYP3A4 inducers tend to lower plasma concen-trations of CYP3A4 substrates, resulting in reduced efficacy of the substrate. This type of drug

Enzyme induction and inhibition SpringerLink

Enzyme induction by increasing the metabolism of drugs may result in important drug interactions. Other implications of enzyme induction include alterations in the metabolism of endogenous substrates, vitamins and activity of extrahepatic enzyme system. Similarly a wide range of drugs may produce clinically significant drug interactions following enzyme inhibition. Assessment of enzyme

PHASE I AND II ENZYME INDUCTION AND INHIBITION BY

by enzyme inhibitors. 1 Based on the short half-life of most inhibitors, inhibition can occur over just a few days. A less intui-tive approach is needed when estimating the time course of interactions caused by enzyme induction. Rifampin is known to induce multiple enzymes responsible for drug metabolism including cytochrome P450 (CYP)1A2, CYP2C8, CYP2C9, CYP2C19, CYP3A4, and some gluc

Liver enzyme induction and inhibition: implications for anaesthesia Sweeney, B. P.; Bromilow, J. 2006-02-01 00:00:00 Summary Recent breakthroughs in molecular biology have enabled a reclassification of drug metabolising enzymes based on their amino acid sequence. This has led to a better understanding of drug metabolism and drug interactions. The majority of these drug metabolising enzymes …

Adverse drug reactions role of enzyme inhibition and

enzyme induction leads to an increase in parent drug metabolism and increased formation of metabolites. In the case of enzyme inhibition or reduced enzyme activity, the perpetrator drug (drug that causes the enzyme inhibition) causes a significant increase in the exposure of the victim drug resulting in exaggerated pharmacology or increased off-target toxicity. For example, when the …
