Active Ingredients of Penegra 50mg

Indications for Penegra 50mg

Penegra 50mg is an ED treatment manufactured by the Indian pharmaceutical company Zydus Alidac and is a generic version of Viagra. “Viagra” is the world’s first ED treatment drug, and its active ingredient, sildenafil, has been used for more than 20 years. Penegra 50mg contains the same active ingredient, sildenafil, as Viagra, and is an ED treatment drug that is reliable in terms of efficacy and safety.

Features of Penegra 50mg

The main advantage of Penegra 50mg is that it contains the same active ingredients as the original drug Viagra, but at a much lower cost.

Sildenafil, the active ingredient of Penegra 50mg, has been proven to be effective, with research results showing that more than 70% of people were able to improve ED when taken correctly. However, in the case of “Viagra”, the high drug price was a bottleneck. In that respect, it can be said that the drug price of Penegra 50mg is quite good at cost performance.

When comparing the active ingredient sildenafil dose of 100mg, the price per Penegra 50mg is less than half of “Viagra”. In the case of sildenafil 100mg tablets, it is also possible to divide the dose into 1 tablet using a pill cutter. By doing so, you can further reduce costs.

For ED that is not covered by insurance, it can be said that even those who were hesitant about treatment due to the high cost of treatment can easily start treatment with Penegra 50mg.

Contains the same active ingredients as the world’s first ED drug, Viagra

The active ingredient of Penegra 50mg is sildenafil, which is the same as the original drug Viagra. Sildenafil is commonly called a PDE5 inhibitor.

An erection occurs when muscles in the corpus cavernosum inside the penis relax and the blood vessels dilate. The widening of the blood vessels allows more blood to flow into the penis, causing the penis to become hard and erect.

At this time, phosphodiesterase 5 (PDE5) decomposes a substance called cyclic guanosine monophosphate (cGMP), which controls muscle relaxation in the corpus cavernosum. Sildenafil inhibits the action of this degrading enzyme, PDE5, and promotes normal muscle relaxation and vasodilation.

Sildenafil has a long track record of use in Viagra, and is an active ingredient whose safety has been ensured. Even those who are taking ED medicine for the first time can take it with confidence.

It is a therapeutic drug with high cost performance that contains a maximum dose of 100mg of active ingredients.

The active ingredient of Penegra 50mg is sildenafil, which has a maximum dose of 100mg even in the original drug Viagra. Since Penegra 50mg contains 100mg per tablet, it can be said to be a highly cost-effective therapeutic drug compared to “Viagra” and other generic drugs.

However, in USA, the maximum dose of sildenafil per dose is 50mg, and the usual usage and dosage is 1/4 to 1/2 tablet (sildenafil 25mg to 50mg). Especially for those who are taking medicines containing sildenafil for the first time and those who are 65 years of age or older, the starting dose should be 1/4 tablet (sildenafil 25mg). In that case, it is possible to divide one tablet with a pill cutter.
