    Metoprolol absorption


    Three extended release formulations of metoprolol (95 mg metoprolol succinate) with different in vitro release rates were administered to ten healthy males (20–29 years) as single oral doses. The bioavailability properties of the three formulations were evaluated in relation to an intravenous dose (10 mg metoprolol tartrate) and an oral solution (95 mg metoprolol succinate). Both the rate and extent of metoprolol absorption were related to the drug release rate as shown by the plasma concentration-time profiles and resultant pharmacokinetic variables. Individual absorption-time profiles reflected well the corresponding in vitro release curves, showing a good correlation over the entire time interval for all three formulations. For the slowest formulations, drug absorption continued at very delayed times (24–30 h) in most individuals, confirming the good distal gastrointestinal absorption of metoprolol. A reduced bioavailability was seen with all extended release formulations compared with the solution and was probably caused by increased hepatic first-pass metabolism. Incomplete absorption may also contribute to the more markedly reduced bioavailability of the slowest formulation.

Based on evidence-based guidelines for pharmacologic treatment for episodic migraine prevention in adults from the American Academy of Neurology and the American Headache Society, metoprolol is effective for migraine prevention in adults. Based on the American College of Cardiology/American Heart Association/Heart Rhythm Society (ACC/AHA/HRS) guidelines for the management of adult patients with supraventricular tachycardia, the use of an oral or intravenous beta-blocker, including metoprolol, is effective and recommended for a variety of symptomatic supraventricular tachycardias (atrioventricular nodal reentrant tachycardia [AVNRT], atrioventricular reentrant tachycardia [AVRT], focal atrial tachycardia [AT], and multifocal atrial tachycardia [MAT]). In patients without pre-excitation, intravenous metoprolol is recommended for acute treatment in hemodynamically stable patients and oral metoprolol is recommended for ongoing management of symptomatic supraventricular tachycardias in patients who are not candidates for, or prefer not to undergo, catheter ablation. Intravenous or oral metoprolol may be useful for rate control in the acute treatment or ongoing management of hemodynamically stable patients with atrial flutter. Based on the American Thyroid Association guidelines for diagnosis and management of hyperthyroidism and other causes of thyrotoxicosis, beta-blockers, including metoprolol, are effective and recommended in the treatment of symptomatic thyrotoxicosis.

    • Hypertension • Angina pectoris • Tachyarrhythmias, in particular supraventricular tachycardia • Maintenance treatment after a myocardial infarction • Prophylaxis of migraine Metoprolol is indicated in adults. Metoprolol tartrate tablets should be administered orally. The dose must always be adjusted to the individual requirements of the patient. The following are guidelines: Hypertension The usual dose is 100mg to 200mg daily, given as a single dose in the morning, or in divided doses (morning and evening). Dose increments should be at weekly intervals thereafter according to individual patient responses. If necessary, it may be taken in combination with other antihypertensive drugs. Angina pectoris The usual dose is 100 to 200 mg daily, given in divided doses (morning and evening). Dose increments should be at weekly intervals thereafter according to individual patient responses. Maximum dose, usually 200mg daily (in divided doses). If necessary, it may be taken in combination with other antianginal drugs. Cardiac arrhythmias The usual dose is 100 to 150 mg per day, in divided doses (in the morning and in the evening). Myocardial infarctions The oral treatment can be initiated once the patient is haemodynamically stable. Metoprolol is absorbed over a large part of the intestine and over 95% of an oral therapeutic dose is generally recovered in the urine as unchanged drug and metabolites. Presystemic elimination accounts for about 50% degradation of acutely administered oral doses. The fraction of the dose available systemically may increase up to 70 to 80% with long term treatment. Since food may enhance the bioavailability of metoprolol the drug should preferably be taken in a standardised way in relation to meals. The drug distributes very rapidly between the blood and various extravascular sites, and only 1 to 2% of the total amount of drug in the body is localised in the blood at apparent distribution equilibrium. The drug diffuses readily across the placenta and the concentration in the umbilical and maternal venous blood is approximately the same. Despite a 3-to 4-fold accumulation in breast milk, adverse reactions in the breast-fed child seem unlikely, unless the child’s hepatic function is severely underdeveloped. The drug is extensively metabolised and only about 5% of an oral dose and 10% of an intravenous dose is excreted in unchanged form -adrenoceptor blocking activity, none of them contributes to the β-blocking effect of metoprolol.

    El sildenafilo (Viagra y genéricos) es un fármaco que pertenece a la familia de los inhibidores de la fosfodiesterasa 5. Junto con otros, como avanafilo (Spedra), tadalafilo (Cialis y genéricos) o vardenafilo (Levitra), estos medicamentos van a producir una intensa dilatación de nuestros vasos sanguíneos. Debido a estos efectos vasodilatadores, va a estar indicado para el tratamiento de la disfunción eréctil debido a que incrementa el riesgo sanguíneo a nuestro pene produciendo erección. Además de esta indicación, también es útil para el tratamiento de la hipertensión arterial pulmonar, una enfermedad rara y muy grave, en la cual se produce un incremento de la presión arterial de los vasos que van en nuestros pulmones dificultando la respiración. La dosis inicial en disfunción eréctil es de un comprimido de 50 miligramos administrado aproximadamente una hora antes de la relación sexual. La administración con alimentos puede retrasar el inicio de los efectos, pero no va a disminuir su intensidad. Posteriormente, en función de los efectos en el paciente las dosis siguientes se pueden mantener entre 25 a 100 miligramos.

    When I met with my surgeon before surgery, he told me that I would be taking Cialis every other day after surgery to help push blood into my penis. When I went to get the catheter removed, he gave me some samples & told me to take it once a week to help with blood flow. He told me to take it a couple days after catheter removal for the first dose. I took it after dinner & that night I seemed to have a little bit better bladder control & stayed drier through the night. Has anyone else experienced similar results or am I nuts? Last of all, has anyone else gotten conflicting info from your doctor such as this change in how often to take the little pill?
