Telmisartan potentiates the ITE-induced aryl hydrocarbon receptor activity in human liver cell line.

Telmisartan is an angiotensin receptor blocker (ARB) approved by the Food and Drug Administration of the US for the treatment of hypertension. It possesses unique pharmacologic properties, including the longest half-life among all ARBs; this leads to a 24-h sustained reduction of blood pressure. Besides well-known antihypertensive and cardioprotective effects, there is also strong clinical evidence that telmisartan confers renoprotection.

Etoricoxib enhances aryl hydrocarbon receptor activity.

Etoricoxib is a nonsteroidal anti-inflammatory drug (NSAID) that possesses properties that include reducing inflammation and relieving pain and fever. Etoricoxib is an oral medication that selectively inhibits cyclooxygenase-2 with high efficacy. Controversies about its cardiovascular side effects have long existed.
