CYP3A4 is a member of the cytochrome P450 superfamily of enzymes.The cytochrome P450 proteins are monooxygenases that catalyze many reactions involved in drug metabolism and synthesis of steroids (including cholesterol), and other lipids.

Many substrates for CYP3A4 are drugs with a narrow therapeutic index, such as amiodarone [10] or carbamazepine. [11] Because these drugs are metabolized by CYP3A4, the mean plasma levels of these drugs may increase because of enzyme inhibition or decrease because of enzyme induction.

A homologous locus is found in mice. The CYP3A locus includes all the known members of the 3A subfamily of the cytochrome P450 superfamily of genes. These ...
Drugs that interact usually share three common features: they are taken orally, normally only a small amount enters systemic blood circulation, and they are metabolized by CYP3A4. [1] The effects on the CYP3A4 in the liver could, in principle, cause interactions with non-oral drugs (e.g. parenteral , inhaled substances , transdermal ...
Many medications can only be broken down and metabolized with the help of an enzyme in your digestive tract called CYP3A4. Grapefruit can block the action of this enzyme, which means more of some ...
Examples of drugs metabolized by CYP3A4 are statins (used to lower cholesterol levels), benzodiazepines (used to treat anxiety and insomnia), calcium channel blockers (used to treat high blood pressure), etc. By measuring 6β-hydroxycortisol levels in clinical trials, researchers can assess whether certain drugs affect the activity CYP3A4 which ...
Solifenacin is metabolized in the liver by the cytochrome P450 enzyme CYP3A4. When administered concomitantly with drugs that inhibit CYP3A4, such as ketoconazole , the metabolism of solifenacin is impaired, leading to an increase in its concentration in the body and a reduction in its excretion.
