    Propranolol vasodilation


    A nonselective β antagonist Propranolol [proe-PRAN-oh-lole] is the prototype β-adrenergic antagonist and blocks both β1 and β2 receptors. Sustainedrelease preparations for once-a-day dosing are available. Figure : Actions of propranolol and other β- blockers. It directly depresses sinoatrial and atrioventricular activity. The resulting bradycardia usually limits the dose of the drug. Cardiac output, work, and oxygen consumption are decreased by blockade of β1 receptors; these effects are useful in the treatment of angina . The β-blockers are effective in attenuating supraventricular cardiac arrhythmias but generally are not effective against ventricular arrhythmias (except those induced by exercise). Peripheral vasoconstriction: Blockade of β receptors prevents β2-mediated vasodilation . propranolol psoriasis Some beta-adrenergic receptor blocking agents (i.e., beta-blockers) are contraindicated in patients with bronchial asthma or with a history of bronchial asthma, or severe chronic obstructive pulmonary disease. In general, beta-adrenergic receptor blocking agents should not be used in patients with bronchospastic diseases. Beta blockade may adversely affect pulmonary function by counteracting the bronchodilation produced by catecholamine stimulation of beta-2 receptors. If beta-blocker therapy is necessary in these patients, an agent with beta-1 selectivity (e.g., atenolol, metoprolol, betaxolol) is considered safer, but should be used with caution nonetheless. Cardioselectivity is not absolute and can be lost with larger doses. The use of beta-adrenergic receptor blocking agents (aka beta-blockers) is contraindicated in patients with sinus bradyarrhythmia or heart block greater than the first degree (unless a functioning pacemaker is present). Due to their negative inotropic and chronotropic effects on the heart, the use of beta-blockers is likely to exacerbate these conditions.

    Isoprenaline, or isoproterenol, is a medication used for the treatment of bradycardia (slow heart rate), heart block, and rarely for asthma. It is a non-selective β adrenoreceptor agonist that is the isopropylamine analog of epinephrine (adrenaline). National Asthma Education and Prevention Program Expert Panel recommends against its use as a nebulizer for acute bronchoconstriction; the use of any beta2-agonists including isoprenaline is not recommended in an asthmatic respiration crisis. It is used to treat heart block and episodes of Adams-Stokes syndrome that are not caused by ventricular tachycardia or fibrillation, in emergencies for cardiac arrest until electric shock can be administered, for bronchospasm occurring during anesthesia, and as an adjunct in the treatment of hypovolemic shock, septic shock, low cardiac output (hypoperfusion) states, congestive heart failure, and cardiogenic shock. Adverse effects of isoprenaline include nervousness, headache, dizziness, nausea, visual blurring, tachycardia, palpitations, angina, Adams-Stokes attacks, pulmonary edema, hypertension, hypotension, ventricular arrhythmias, tachyarrhythmias, difficulty breathing, sweating, mild tremors, weakness, flushing, and pallor. The adverse effects of isoprenaline are also related to the drug's cardiovascular effects. Isoprenaline can produce tachycardia (an elevated heart rate), which predisposes people who take it to cardiac arrhythmias. adrenoceptor stimulation in arteriolar smooth muscle induces vasodilation. Its inotropic and chronotropic effects elevate systolic blood pressure, while its vasodilatory effects tend to lower diastolic blood pressure. However reduction in portal hypertension is possible through the use of nonselective beta blockers, particularly propranolol and Nadolol. These medications reduce portal pressures both by decreasing cardiac output and by producing splanchnic vasoconstriction. Several studies have shown that nonselective beta blockers decrease the risk for first variceal hemorrhage by 40% to 50% when compared to patients taking placebo. First, vasoactive substances such as serotonin, interleukin 1, endothelin 1, and thromboxane, which may cause vasoconstriction and mitogenesis in the pulmonary arteries, escape hepatic detoxifying mechanisms through portosystemic shunts or are not cleared as effectively by the diseased liver. Second, venous thromboemboli arising from the portal vein or other systemic sources may reach the pulmonary circulation through portosystemic shunts, causing pulmonary hypertension. Propranolol: The best beta blocker for rapid heart rate, anxiety and skipped beats that occur with rapid heart rate 5-HT1 (serotonin receptor) antagonism may contribute to reduced anxiety Also blocks physical anxiety manifestations like sweating and tremor Good for POTS/IST due to sympatholythic and vasoconstricting effects. The primary pharmacologic strategy for preventing variceal hemorrhage is use of nonselective beta blockers, particularly propranolol and nadolol.

    Timing of sildenafil therapy in dialysis patients—lessons. amoxicillin versus penicillin Hypotension occurred shortly after the administration of this agent for which no other cause was identified. The exclusion of hypovolaemia as a cause of hypotension in dialysis patients is difficult. In this case a number of factors argue against hypovolaemia. The patient was well and haemodynamically stable before the initiation of sildenafil.
