amlodipine and valsartan (Exforge) (cont.)

Pharmacy Author:
Medical and Pharmacy Editor:

Valsartan is an oral drug that belongs to a class of drugs called angiotensin receptor blockers (ARBs) . Angiotensin, formed in the blood by the action of angiotensin converting enzyme (ACE) on a chemical in blood called angiotensinogen. Angiotensin is a powerful chemical that attaches to angiotensin receptors found in many tissues but primarily on smooth muscle cells surrounding blood vessels. Angiotensin's attachment to the receptors causes the blood vessels to narrow (constrict) which leads to an increase in blood pressure (hypertension). Valsartan blocks the angiotensin receptor. By blocking the action of angiotensin, valsartan dilates blood vessels and reduces blood pressure.

PRESCRIBED FOR: Exforge is used for treating high blood pressure in patients not adequately controlled on one blood pressure medication or for initial therapy if it is not likely that one drug will achieve adequate control.

SIDE EFFECTS: Side effects include:

Angioedema (swelling of soft tissues including those of the throat and larynx) is a rare but serious side effect of valsartan.
