What is Sildenafil CAS 139755-83-2?

Sildenafil is a potent inhibitor of phosphodiesterase 5 (PDE5) with IC50 values of 3.6 and 3 nM for PDE5 activity in isolated rabbit platelets and human corpus cavernosum, respectively. It is selective for PDE5 over PDE1 and PDE3 (IC50s = 0.26 and 65 μM, respectively).

What is sildenafil made from?

In addition to the active ingredient, sildenafil citrate, each tablet contains the following inactive ingredients: microcrystalline cellulose, anhydrous dibasic calcium phosphate, croscarmellose sodium, magnesium stearate, hypromellose, titanium dioxide, lactose, triacetin, and FD & C Blue #2 aluminum lake.

Is sildenafil safe to use?

Sildenafil is not suitable for some people. To make sure it’s safe for you, speak to your doctor or pharmacist before taking sildenafil if you: have ever had an allergic reaction to sildenafil or any other medicine. are taking medicines called nitrates for chest pain (angina)

Is sildenafil as good as Viagra?

Takeaway. Generic Viagra, or sildenafil citrate, works the same as Viagra, but at a lower cost. While Pfizer still manufactures the “little blue pill,” other companies, globally and in the U.S., make sildenafil. It may look different, but it’s still an effective treatment for ED.

What is the difference between sildenafil and Viagra?

Generic Viagra (sildenafil) and Viagra are the same medication, and the active ingredient is sildenafil citrate in both drugs. It is this ingredient that helps treat erectile dysfunction. The main difference between these two drugs is the cost. Generic drugs are always less expensive than branded drugs.
