Irbesartan It is an angiotensin II receptor (type AT1) antagonist. Irbesartan blocks the vasoconstriction and aldosterone secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptors found in vacular smooth muscle, adrenal gland etc. Indications: Mild to moderate hypertension etc. Side Effects: Diarrhea, headache, dizziness, nausea, upper respiratory …
Oxeprenolol: It is non selective beta blocker with intrinsic sympathomimetic activity. Due to its non selectivity, it can also block beta receptors in lungs and cause severe side effects. It passes blood brain barrier more easily than other beta blockers because of its lipophilic property. It is also more likely to cause CNS related side …
Pindolol: It is non selective beta blockers with partial beta adrenergic receptor agonist property. It lowers blood pressure, heart rate and strain on the heart by blocking beta receptors. It has intrinsic sympathomimetic activity. It also shows membrane stabilizing effects. Indications: Hypertension, angina pectoris etc Side effects: Anxiety, depression, headache, diarrhea, nausea, dry or burning …
Lidocaine: Other names: Lignocaine Lidocaine is a local anesthetic agent. It is used as local anesthetic as well as antiarrhythmic. The most prominent cardiac action is suppression of automaticity in ectopic foci. Lidocaine is also used topically to relieve in burning, itching and pain in skin inflammation. It is injected as an anesthetic in dental …
Nebivolol: It is β-1 adrenoreceptor selective inhibitors. It has high selectivity for β adrenoreceptor. Mode of Action: It is beta blocker and works by slowing down the heart rate and reducing amount of blood it pump out in blood vessels. This action reduces blood pressure. Indications: Essential hypertension, heart failure Side Effects: Headache, fatigue, dizziness, …
Carvedilol: Carvedilol is class of antagonists of both α and β andrenoceptor. Like Labetalol, Carvedilol is also reversible of β-blockers with concurrent α1- blocking agents that lead to peripheral vasodilation and reduce blood pressure. Carvedilol exerts antihypertensive effect partly by reducing total peripheral resistance and vasodilation by blocking α-1 adrenoreceptors and by inhibiting β-adrenoreceptor-mediated compensatory …
Labetalol: Labetalol is antagonist of both α & β andrenoceptors. Labetalol is reversible β-blockers with concurrent α1 blocking actions that produce peripheral vasodilation, thereby reducing blood pressure. Labetalol prevents vasoconstriction and helpful in patients for whom increased peripheral vascular resistance is undesirable. Labetalol does not interfere with serum lipid level and blood sugar level. Labetalol …
AmrinoneAmrinone acts by inhibiting the breakdown of both cAMP and cGMP by the phosphodiesterase (PDE3) enzyme. Positive inotrope with direct pulmonary vasodilator activity increase cardiac output and use in the treatment of cardiac heart failure. Indications: Congestive Heart Failure etc. Side Effects: Cardiac arrhythmia, hepatotoxicity, GI disturbance, myositis, nail discoloration, nausea, hypersensitivity, chest pain etc. …
Quinidine: It is alkaloid from Cinchona bark-the dextroisomer of quinine & has been noted to suppress ‘rebellious palpitation’. Quinidine increase threshold for excitation and reduces conduction velocity, thus limits the spread of arrhythmia. Mode of Action: Quinidine produces its action by blocking inward sodium current. Its action is use dependent means at higher heart rates …
Eplerenone Eplerenone is an aldosterone blocker. It works by blocking the hormone aldosterone, which lowers the amount of sodium and water the body retains. This helps to lower blood pressure to help prevent strokes, heart attacks, and kidney problems. Indications: Congestive Heart failure, post myocardial infractions, hypertension etc. Side effects: Hyperkalaemia, hyponatraemia, hypercholesterolemia, albumin urea, …
