Descripción del producto:

En 16 separar 4-24 week trials of men (sobre 18 years old) who suffered from impotence for longer than 6 meses, dosages between 10-200 mgs were administered. Significant improvements in erectile function, including frequency of penetration as well as erection duration post penetration, were reported with Sildenfil treatment compared to the placebo group.

Erections were improved in 72% of the Viagra group verses 18% of the placebo group. In all cases effects were dependant upon dosage and improvement was the greatest when dosage exceeded 100 mgs. Responses were decreased by 40-60% in patients suffering from diabetes and prostatectomy, respectively. Withdrawal rates were less than 5% related to negative side effects and limited response rates.

Vardenafil’s indications and contra-indications are the same as with other PDE5 inhibitors; it is closely related in function to sildenafil citrate (viagra) and tadalafil (cialis). Sildenafil Citrate is solely active in relaxing muscles and increasing blood flow to the heart, lungs and penis due to PDE-5, yet vasodilation is not increased in other parts of the body.

Solicitud:

Citrato de sildenafilo, sold as Viagra, Revatio and under various other trade names, is a drug used to treat erectile dysfunction and pulmonary arterial hypertension (PAH).

tadalafil’s pharmacologic distinction is its longer half-life (17.50 horas) – compared to sildenafil (4.0–5.0 hours) and vardenafil (4.0–5.0 hours) – resulting in longer duration of action, and so partly responsible for “The Weekend Pill” sobriquet. además, the longer half-life is the basis for current investigation of tadalafil’s daily therapeutic use in relieving pulmonary arterial hypertension. Sildenafil is approved in several world regions as a thrice-daily therapy for pulmonary arterial hypertension.

Citrato de sildenafilo 50 mg is the recommended starting dose for men with erectile dysfunction (ED); sin embargo, most men are later titrated to sildenafil 100 mg for improved efficacy.
