Peoria, AZ. Sep 21, 2004. #2. From what I've learned in pharmacy school so far is that most drugs are metabolized by the P450 enzymes, but not all. The most common P450 family is 3A4 and will be the concern for the most drug interactions. Some drugs induce, whereas others inhibit the substrate Patients who have sulfa (sulfonamide) allergies will have a wide range of allergies to the following sulfa drug And we at USMLE Insider Prep Course have created excellent Tables with the most important substrates, inhibitors, and inducers of these isoenzymes just as we have shown here for CYP3A4. Some drugs are influenced by multiple CYP isoenzymes and are therefore susceptible to multiplicity of drug-drug interactions

  3. Amiodarone is metabolized hepatically and serves as a substrate primarily for cytochrome P-450 (CYP) 3A4. In addition, it is a potent inhibitor of CYP 3A4, 2C9, 2D6, and 1A2. 2 As a result, concurrent use of CYP 3A4 inhibitors can cause levels of amiodarone to increase and the use of CYP 3A4 inducers can result in decreased concentrations of.
  4. The cytochrome P450 superfamily (CYP450) is a large and diverse group of enzymes that form the major system for metabolizing lipids, hormones, toxins, and drugs in the liver. The CYP450 genes are very polymorphic and can result in decreased, absent, or increased enzyme activity

Inhibition or induction of CYP450 drug metabolizing isozymes is the most common mechanism by which clinically important drug interactions occur. The most common isozyme is CYP3A4, followed by 2C19, 2C9, 1A2, 2E6, and 2D6. Drugs interacting with CYP450 isozymes can be classified as substrates, inducers, or inhibitors This advice is correct because warfarin is metabolized and inactivated by the cytochrome P-450 (CYP450) enzyme complex, and grapefruit juice is an inhibitor of CYP450. Therefore, when grapefruit juice is consumed, the efficacy of inactivation of drugs, like warfarin, is impaired, which increases the effective level of warfarin circulating in.
