The clinical uses and pharmacokinetic properties of Sildenafil are as follows:
The metabolism of Sildenafil and Sildenafil citrate by the CYP2D6 enzyme is complex and not fully understood. Sildenafil and Sildenafil citrate primarily hydrolyze the active metabolites, which are primarily excreted via the liver. The hydrolysis of Sildenafil is primarily due to the active metabolite conjugate of Sildenafil (C23H36N2O). The metabolites of Sildenafil are primarily excreted unchanged in the urine (C24H28N2O) and the feces (C12H11N2O) in approximately 1%. Sildenafil, the principal metabolite of Sildenafil, primarily hydrolyzed the C23H28N2O metabolites to the inactive metabolite, C24H28N2O, which is the active metabolite of Sildenafil.
In the case of Sildenafil, CYP2D6 activity is thought to be one of the major targets of the drug. The active metabolite of Sildenafil, which is the primary active metabolite, was identified to be the major active metabolite of sildenafil, as well as the major active metabolite of sildenafil, which is the inactive metabolite of sildenafil. Sildenafil and its SILDENAFIL metabolite C23H28N2O are both active metabolites of sildenafil, but are much less active than Sildenafil. Sildenafil and its SILDENAFIL are approximately 17.9% and 19%, respectively, of the total SILDENAFIL and SILDENAFIL are about 1.8% and 1.0%, respectively. The half-life of the drug is approximately 14 hours, and it is approximately 17 hours after dosing. The half-life of sildenafil is about 3 hours, while the half-life of sildenafil citrate is approximately 17 hours.
The metabolism of Sildenafil and Sildenafil citrate by CYP2D6 is complex. Sildenafil is primarily metabolized by CYP2D6, whereas sildenafil is primarily hydrolyzed by CYP2D6 to the active metabolite, C23H28N2O. Sildenafil and SILDENAFIL are both metabolized to the active metabolite, C24H28N2O, which is the major active metabolite of Sildenafil. Sildenafil, the principal metabolite of sildenafil, primarily hydrolyzed the C23H28N2O metabolites to the inactive metabolite, C24H28N2O, which is the major active metabolite of Sildenafil. The metabolism of Sildenafil by CYP2D6 is mainly due to the C23H28N2O metabolite.
The cheapest erectile dysfunction (ED) pills are generic Viagra, called.
The term "generic" refers to the active ingredient of a medicine or drug rather than to the advertised brand name under which the medicine is sold. It is a term referring to any drug marketed under its chemical name without advertising.
Pfizer made the originaltablet that is often referred to as the “blue pill”.The patent expired in 2013 which then allowed other pharmaceutical manufactures to make a generic version under the name of the active ingredient called Sildenafil. They are exactly the same medically and perform in the same way with the same side-effects.
As with most branded products, Viagra is sold at a higher price,therefore the generic tablets sold asare much cheaper.
Medically there is no difference between a generic medicine and the branded medicine, as they both have the same active ingredients to make them perform in the same way. They only differ in the “bulking” agents used to fill the tablet as the amount of active ingredient required, in this case Sildenafil, is very small. This makes the tablets bigger and easier to handle.
The main difference between generic andbranded named prescription medicines is cost with generics being much cheaper
Every pharmacy can choose what price they sell at, as there are no fixed prices. It will depend on what price the pharmacy can buy the drug from the wholesaler and the cost of their own overheads. They can they decide what mark-up they require and some pharmacies choose to sell some products at higher prices.
