Active ingredients in C09DB

Active Ingredient Description
Candesartan and Amlodipine

Combination of two antihypertensive compounds with complementary mechanisms to control blood pressure in patients with essential hypertension: an angiotensin II receptor antagonist, candesartan and a dihydropyridinic calcium channel blocker, amlodipine. The combination of these substances has an additive antihypertensive effect, reducing blood pressure to a greater degree than either component alone.

Irbesartan and Amlodipine

The pharmacodynamic properties of each drug, irbesartan and amlodipine, provide an additive antihypertensive effect when administered in combination compared to the effect of each drug administered separately. Irbesartan is a specific angiotensin II receptor antagonist (AT1 subtype) and amlodipine is a dihydropyridine calcium antagonist. Both AT1 receptor antagonists and calcium channel blockers lower blood pressure by reducing peripheral resistance, but calcium influx blockade and reduction of angiotensin II vasoconstriction are complementary mechanisms.

Olmesartan medoxomil and Amlodipine

Combination of an angiotensin II receptor antagonist, olmesartan medoxomil, and a calcium channel blocker, amlodipine besilate. The combination of these active ingredients has an additive antihypertensive effect, reducing blood pressure to a greater degree than either component alone.

Telmisartan and Amlodipine

Combination of two antihypertensive compounds with complementary mechanisms to control blood pressure in patients with essential hypertension: an angiotensin II receptor antagonist, telmisartan, and a dihydropyridinic calcium channel blocker, amlodipine. The combination of these substances has an additive antihypertensive effect, reducing blood pressure to a greater degree than either component alone.

Valsartan and Amlodipine

Combination of two antihypertensive compounds with complementary mechanisms to control blood pressure in patients with essential hypertension: amlodipine belongs to the calcium antagonist class and valsartan to the angiotensin II antagonist class of medicines. The combination of these substances has an additive antihypertensive effect, reducing blood pressure to a greater degree than either component alone.
