Forasartan
Overview[edit | edit source]
Forasartan is a pharmaceutical compound that belongs to the class of angiotensin II receptor antagonists, commonly known as angiotensin receptor blockers (ARBs). These medications are primarily used in the management of hypertension (high blood pressure) and are also beneficial in treating certain types of heart failure.
Mechanism of Action[edit | edit source]
Forasartan works by selectively blocking the binding of angiotensin II to the angiotensin II receptor type 1 (AT1 receptor) in various tissues, including the vascular smooth muscle, adrenal gland, and kidney. This inhibition prevents the vasoconstrictive and aldosterone-secreting effects of angiotensin II, leading to vasodilation, reduced blood pressure, and decreased workload on the heart.
Pharmacokinetics[edit | edit source]
Forasartan is administered orally and is well absorbed from the gastrointestinal tract. It undergoes hepatic metabolism and is excreted primarily in the urine and feces. The drug has a relatively long half-life, allowing for once-daily dosing in most patients.
Clinical Uses[edit | edit source]
Forasartan is indicated for the treatment of:
- Hypertension: It helps in lowering blood pressure and reducing the risk of cardiovascular events.
- Heart failure: It is used to improve symptoms and reduce mortality in patients with heart failure.
- Diabetic nephropathy: It can slow the progression of kidney disease in patients with type 2 diabetes and hypertension.
Side Effects[edit | edit source]
Common side effects of forasartan include:
- Dizziness
- Headache
- Fatigue
- Hyperkalemia (elevated potassium levels)
Less common but serious side effects may include:
Contraindications[edit | edit source]
Forasartan is contraindicated in patients with:
- Hypersensitivity to the drug or any of its components
- Pregnancy, due to the risk of fetal toxicity
- Severe renal artery stenosis
Drug Interactions[edit | edit source]
Forasartan may interact with other medications, such as:
- Nonsteroidal anti-inflammatory drugs (NSAIDs), which can reduce its antihypertensive effect
- Potassium-sparing diuretics and potassium supplements, which can increase the risk of hyperkalemia
