Other antiepileptic drugs such as ethosuximide (metabolized by CYP 3A4, CYP 2E), clonazepam (metabolized by CYP 3A4), felbamate (metabolized by CYP 3A4, CYP 2E1), tiagabine (metabolized by CYP 3A4), and zonisamide (metabolized by CYP 3A) may also be susceptible to the interaction with COVID-19 vaccines, though there are no previous reports of
Concomitant Use with Strong Inhibitors of CYP 3A4: Use of pdp-AMLODIPINE with drugs that result in strong inhibition of CYP 3A4, such as
Drug-Drug Interactions Cytochrome P450 3A4: Rosuvastatin clearance is not dependent on metabolism by cytochrome P450 3A4 to a clinically significant extent [1k] Cyclosporine: Combination increases rosuvastatin exposure.
Grapefruit juice (GJ), a cytochrome P450 (CYP) 3A4 inhibitor, may affect the pharmacokinetics of drugs metabolized through CYP 3A4. Losartan, an angiotensin II
It is recommended to use a statin not metabolised by CYP 3A4 when given with amiodarone. Other drugs metabolised by cytochrome P450 3A4: examples of such

The effects of concomitant use or discontinuation of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with codeine are complex. Use of cytochrome P450 3A4 inducers, 3A4 inhibitors, or 2D6 inhibitors with codeine sulfate requires careful consideration of the effects on the parent drug, codeine, and the active metabolite, morphine.

Sildenafil is metabolized mainly by the cytochrome P450 3A4 pathway (79%) and to a lesser extent by 2C9 (20%). 14,15 Vardenafil is metabolized in a similar manner, mainly by 3A4 with a smaller contribution by 2C9. 15 Tadalafil is metabolized almost solely by 3A4. 15 Therefore, drugs that inhibit the 3A4 pathway decrease the metabolism and increase the plasma
