Toprol-XL is a beta1-selective (cardioselective) adrenoceptor blocking agent, for oral administration, available as extended release tablets. It has been formulated to provide a controlled and predictable release of metoprolol for once-daily administration. The mechanism of the antihypertensive effects of beta-blocking agents is not fully known. However, several possible mechanisms have been proposed: (1) competitive antagonism of catecholamines at peripheral (especially cardiac) adrenergic neuron sites, leading to decreased cardiac output; (2) a central effect leading to reduced sympathetic outflow to the periphery; and (3) suppression of renin activity. Metoprolol blocks the catecholamine-induced increases in heart rate, velocity and extent of myocardial contraction, and in blood pressure, metoprolol reduces the oxygen requirements of the heart at any given level of effort. Tthe precise mechanism for the beneficial effects of beta-blockers in heart failure is not known. Toprol-XL is specifically indicated for: the treatment of hypertension, either alone or in combination with other antihypertensive agents, the long-term treatment of angina pectoris and the treatment of stable, symptomatic (NYHA Class II or III) heart failure of ischemic, hypertensive, or cardiomyopathic origin. buy viagra online in dubai After experiencing a combination of 'irregular heartbeats', fatigue and some elevated blood pressure, I was recently tested, and told I was having about 3,000 PACs a day. Otherwise, my Echo and Holtor tests were excellent. My Doctor prescribed taking 12.5mg of metoprolol a day, even though he acknowledges that there is only a moderate chance that it will address and improve the problem. Having heard some of the more extreme cases of the potential side-effects of metoprolol, I was wondering... a.) Am I likely to experience many side-effects at such a small dosage?

I was glad to read your post concerning the Toprol XL, I haven't had any nightmares with mine, been on it for approx 6-7 yrs. b.)

I was prescribed Toprol XL at the same dosage and had horrible nightmares and depression. However, it prevented me from having any more episodes of afib which I had as a result of pregnancy.
