Introduction Brilinta is the brand name of ticagrelor, an oral antiplatelet drug used mainly to prevent thrombotic cardiovascular and cerebrovascular events. It belongs to the P2Y12 platelet receptor inhibitor class and is commonly used in patients with acute coronary syndrome, history of myocardial infarction, coronary artery disease at high risk of thrombotic events, and selected … Read more
Introduction Verquvo is the brand name of vericiguat, an oral soluble guanylate cyclase stimulator used in selected adults with symptomatic chronic heart failure. It is mainly used in patients with heart failure and ejection fraction less than 45% who have recently had worsening heart failure requiring hospitalization or outpatient intravenous diuretic therapy. Its clinical role … Read more
Introduction Vasodilators are a diverse group of drugs that produce relaxation of vascular smooth muscle, resulting in widening of blood vessels and improved blood flow. They are commonly used in the management of hypertension, heart failure, angina pectoris, hypertensive emergencies, pulmonary hypertension, and various cardiovascular disorders. The therapeutic effects of vasodilators arise from their ability … Read more
Introduction Glyceryl Trinitrate (GTN), commonly known as nitroglycerin, is an organic nitrate widely used in the treatment of angina pectoris and acute coronary syndromes. It acts primarily as a vasodilator by releasing nitric oxide (NO), which relaxes vascular smooth muscle. GTN reduces myocardial oxygen demand by decreasing preload and also improves coronary blood flow through … Read more
Introduction Bosentan is an oral endothelin receptor antagonist (ERA) used primarily for the treatment of pulmonary arterial hypertension (PAH). Endothelin-1 (ET-1) is one of the most potent vasoconstrictors in the human body, and its overactivity plays a central role in the pathophysiology of PAH by causing vasoconstriction, vascular hypertrophy, smooth muscle proliferation, and fibrosis. Bosentan … Read more
Introduction Vericiguat is a soluble guanylate cyclase (sGC) stimulator used in patients with chronic heart failure with reduced ejection fraction (HFrEF) following hospitalization or intravenous diuretics. It enhances the nitric oxide (NO)–sGC–cGMP pathway to support cardiovascular function. Step-by-Step Mechanism of Action Pharmacokinetic Parameters Clinical Uses Adverse Effects Comparative Analysis Feature Vericiguat (sGC Stimulator) Nitrates PDE5 … Read more
