Weight gain can occur as a side effect of some beta blockers, especially the older ones, such as atenolol (Tenormin) and metoprolol (Lopressor, Toprol-XL). The average weight gain is about 2.6 pounds (about 1.2 kilograms). Newer beta blockers, such as carvedilol (Coreg), don't usually cause weight gain as a side effect. Weight may rise in the first weeks of taking the beta blocker and then generally stabilizes. However, the beta blockers that can cause weight gain usually aren't prescribed unless other medications haven't worked, or if you have a specific heart condition that requires taking those medications. Beta blockers are used to treat a host of conditions, including high blood pressure, heart failure, migraines, glaucoma and anxiety. Doctors aren't sure exactly why some beta blockers cause weight gain. buy ventolin inhaler at asda Is its relative lack of most of the bronchoconstrictive effects in patients with chronic obstructive pulmonary disease. Acute intravenous dosage is 1.0 mg titrated to therapeutic effect up to 0.1 to 0.2 mg/kg.). It is lipid soluble and has a high first pass hepatic metabolism resulting in the need for high oral doses (100-200 mg/day) compared to intravenous doses of 2.5 to 5 mg, titrated to effect. It is roughly half as potent as propranolol, and maximum β1-blockade effect is achieved at 0.2 mg/kg. Atenolol is also β1 selective, is lipophilic, and has an elimination half-life of 6 hours. Even so, the effect of an oral dose of 25 to 100 mg lasts 24 hours. In a recent study, perioperative blockade with atenolol resulted in a reduced short- and long-term mortality in high-risk patients having noncardiac surgery compared with -adrenergic receptor blocker that is metabolized by plasma esterases.

The potency of metoprolol for β1-receptor blockade is equal to that of. It is lipid soluble and has a high first pass hepatic metabolism resulting in the need for. Metoprolol is a cardioselective β1-adrenergic blocking agent used for acute myocardial infarction (MI), heart failure, angina pectoris and mild to moderate hypertension. It may also be used for supraventricular and tachyarrhythmias and prophylaxis for migraine headaches. Metoprolol is structurally similar to bisoprolol, acebutolol and atenolol in that it has two substituents in the para position of the benzene ring. The β1-selectivity of these agents is thought to be due in part to the large substituents in the para position. At low doses, metoprolol selectively blocks cardiac β1-adrenergic receptors with little activity against β2-adrenergic receptors of the lungs and vascular smooth muscle. Unlike propranolol and pindolol, metoprolol does not exhibit membrane-stabilizing or intrinsic sympathomimetic activity. Membrane-stabilizing effects are only observed at doses much higher than those needed for β-adrenergic blocking activity. Metoprolol possesses a single chiral centre and is administered as a racemic mixture. Metoprolol is used for a number of conditions, including hypertension, angina, acute myocardial infarction, supraventricular tachycardia, ventricular tachycardia, congestive heart failure, and prevention of migraine headaches. receptors in the heart, metoprolol is also prescribed for off-label use in performance anxiety, social anxiety disorder, and other anxiety disorders. Metoprolol is sold in formulations that can be taken by mouth or given intravenously. Side effects, especially with higher doses, include dizziness, drowsiness, fatigue, diarrhea, unusual dreams, trouble sleeping, depression, and vision problems. Metoprolol may also reduce blood flow to the hands or feet, causing them to feel numb and cold; smoking may worsen this effect. Due to the high penetration across the blood-brain barrier, lipophilic beta blockers such as propranolol and metoprolol are more likely than other less lipophilic beta blockers to cause sleep disturbances such as insomnia and vivid dreams and nightmares. Serious side effects that are advised to be reported immediately include symptoms of bradycardia (resting heart rate slower than 60 beats per minute), persistent symptoms of dizziness, fainting and unusual fatigue, bluish discoloration of the fingers and toes, numbness/tingling/swelling of the hands or feet, sexual dysfunction, erectile dysfunction, hair loss, mental/mood changes, depression, breathing difficulty, cough, dyslipidemia and increased thirst.
