Sildenafil Citrate (Sildenon) 50 mg

Sildenon (Sildenafil Citrate) 50 mg is Utinon's on-demand PDE5 inhibitor, supplied as 25 tablets. Sildenafil is the active compound in Viagra, with a fast onset and a short half-life. Each box is sealed and carries a scratch-off authenticity code inside.

What Sildenon 50MG Is

Sildenafil citrate is a selective phosphodiesterase type 5 inhibitor. It blocks the enzyme that degrades cyclic GMP, prolonging smooth-muscle relaxation and improving blood flow. A box holds 25 tablets at 50 mg, for 1,250 mg total. The 50 mg unit is the standard starting strength, half the 100 mg maximum.

The History of Viagra

Sildenafil was developed by Pfizer and approved in 1998 as Viagra, the first oral PDE5 inhibitor. It was originally studied as a cardiovascular drug before its effects on erectile function were recognised. Its approval transformed the treatment of erectile dysfunction and established the PDE5 class that vardenafil and tadalafil later joined.

How It Works

Sildenafil inhibits PDE5, preventing cyclic GMP breakdown and sustaining smooth-muscle relaxation. Absorption is fast, with peak levels within an hour, but a heavy meal slows it. It is metabolised mainly by hepatic CYP3A4, and the half-life is roughly four hours, so the effect lasts through a defined window. The drug also has mild activity at PDE6, which explains the visual side effects sometimes reported.

What the Research Shows

• Sildenafil was the first oral PDE5 inhibitor approved for clinical use.
• Its onset is fast and its duration is shorter than tadalafil.
• Absorption is slowed by a high-fat meal.
• CYP3A4 metabolism and a four-hour half-life define the dosing window.

Research Context

Sildenafil is the reference PDE5 inhibitor. Research on the class began with it, and every later comparison uses it as the baseline for onset, duration and selectivity. The 50 mg tablet is the standard starting strength and the usual comparator dose. Its short half-life makes it the on-demand end of the class, in contrast with daily tadalafil. That difference in duration, rather than any large gap in peak effect, is what separates the two in practical research designs.

Strength, Pack and Authentication

Each tablet contains 50 mg of sildenafil citrate, and the box holds 25 tablets. The carton is printed and tamper-evident, stating the compound, strength and tablet count. A scratch-off security code inside the box links the pack to Utinon's manufacturing records, and the blister format keeps every tablet protected from moisture and light until it is used.
