Exforge is used together to make a combined antihypertensive preparation. Amlodipine is a calcium channel blocker. It relaxes peripheral and coronary vascular smooth muscle.
It produces coronary vasodilation by inhibiting the entry of calcium ions into the slow channels or select voltage-sensitive channels of the vascular smooth muscle and myocardium during depolarization. It also increases myocardial oxygen delivery in patients with vasospastic angina.
This drug is widely used by the healthcare professional to treat a variety of health disorders like mild to moderate hypertension, chronic stable and vasospastic angina, coronary artery disease, hypertension, and Raynaud’s disease etc.
This medicine is used alone or in combination with other medicines to relieve chest pain and to treat hypertension. On the contrary, valsartan is an angiotensin II type 1 receptor blocker which produces its blood pressure lowering effects by inhibiting angiotensin II-induced vasoconstriction, aldosterone release and renal reabsorption of Na.
This medicine is available in tablet form. You can get this combined medicine only with your doctor's prescription.
Before using Exforge, the risk and benefit ratio of taking the drug should be considered. This is a decision that your doctor will make with your active participation.
There are some important factors such as drug interaction, metabolic impairment, hypersensitivity reaction, pregnancy, lactation etc. which may alter the drug action.
Sometimes presence of other health disorders affects the beneficial effects of this medicine and even may cause serious complications. Make sure you mention your doctor if you have any other medical problems.
The use of amlodipine is contraindicated if there is history of hypersensitivity reactions to amlodipine or other calcium channel blocker. This combined antihypertensive formulation should not be used in patients with known hypersensitivity to dihydropyridines.
Certain drugs should not be used concurrently with such medications. Plasma concentrations may be elevated with azole antifungals and ritonavir. Valsartan may antagonize hypotensive effects and increase the risk of renal impairment with NSAIDs.
There is increased risk of hyperkalemia with potassium-sparing diuretics, potassium supplements, or potassium containing salt substitutes.
Thus, it is always recommended to consult with your doctor if you are in need of some drugs for another health problem in order to avoid unwanted serious complications.
Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans. But potential benefits may warrant use of the drug in pregnant women despite potential risks.
