Prescription required? Yes. YesViagra (sildenafil) is classified as a phosphodiesterase 5 enzyme inhibitor. Viagra is approved for the treatment of erectile dysfunction (ED). Viagra, like any medication has possible side effects and warnings associated with its use. One of the possible effects Viagra can have is to lower blood pressure. Therefore the medication should be used in caution with patients that have left ventricular outflow obstruction and should only be used in patients that are hemodynamically stable prior to starting therapy. Also the medication is recommended to use with caution in patients that have life threatening arrthythmias, heart attack or stroke within the last six months, cardiac failure, coronary artery disease resulting in unstable angina, or in patients with left ventricular outflow obstruction. Some of these conditions have not been studied with the use of Viagra. who makes viagra

Absorption and Distribution: Viagra is rapidly absorbed. Maximum observed plasma concentrations are reached within 30 to 120 minutes (median 60 minutes) of oral dosing in the fasted state. When Viagra is taken with a high fat meal, the rate of absorption is reduced, with a mean delay in Tmax of 60 minutes and a mean reduction in Cmax of 29%. The mean steady state volume of distribution (Vss) for sildenafil is 105 L, indicating distribution into the tissues. Sildenafil and its major circulating N-desmethyl metabolite are both approximately 96% bound to plasma proteins. Protein binding is independent of total drug concentrations.Product Type HUMAN PRESCRIPTION DRUG LABEL Item Code (Source) NDC:0173-0829

In subjects with end-stage renal disease on hemodialysis, there was a two-fold increase in Cmax and 2.7- to 4.8-fold increase in AUC following single-dose administration of 10 or 20 mg tadalafil. Exposure to total methylcatechol (unconjugated plus glucuronide) was 2- to 4-fold higher in subjects with renal impairment, compared to those with normal renal function. Hemodialysis (performed between 24 and 30 hours post-dose) contributed negligibly to tadalafil or metabolite elimination. In a clinical pharmacology study (N=28) at a dose of 10 mg, back pain was reported as a limiting adverse event in male patients with creatinine clearance 30 to 50 mL/min. At a dose of 5 mg, the incidence and severity of back pain was not significantly different than in the general population. In patients on hemodialysis taking 10- or 20-mg tadalafil, there were no reported cases of back pain.

AUSTRALIAVIAGRA was shown to potentiate the hypotensive effects of nitrates and its administration in patients who use nitric oxide donors such as organic nitrates or organic nitrites in any form is therefore contraindicated [see Contraindications (4.1), Drug Interactions (7.1), and Clinical Pharmacology (12.2)].Generic medicines have their components (medicinal ingredient and excipients alike) identical to those of the original medicine. This ensures that both brand and generic medicines are identical in their mechanisms and effects.
