Viagra (Sildenafil Citrate) 50 mg – 30 Tablets

Biochem Viagra (Sildenafil Citrate) 50 mg – 30 Tablets | Oral PDE5 Inhibitor

Biochem Viagra (Sildenafil Citrate) 50 mg – 30 Tablets is an oral pharmaceutical product. This product contains sildenafil citrate, a selective phosphodiesterase type 5 inhibitor used in the medical management of erectile dysfunction.

Sildenafil is associated with the pharmaceutical brand name Viagra and was among the first PDE5 inhibitors widely introduced for erectile dysfunction treatment.

Sildenafil acts by inhibiting PDE5, an enzyme responsible for the breakdown of cyclic guanosine monophosphate (cGMP).

During sexual stimulation, nitric oxide release promotes cGMP production in penile erectile tissue.

By reducing cGMP degradation, sildenafil enhances smooth muscle relaxation and supports increased penile blood flow.

Sildenafil does not independently produce an erection in the absence of sexual stimulation and is not classified as an aphrodisiac.

The compound has an approximate elimination half-life of four hours, although its pharmacological effects vary between individuals.

Sildenafil also has established medical applications in pulmonary arterial hypertension under separate product indications and dosing frameworks.

Sildenafil is not testosterone, an anabolic steroid, a hormone replacement product, or a treatment for all causes of sexual dysfunction.

Biochem Viagra 50 mg contains sildenafil citrate in an amount corresponding to the stated 50 mg tablet strength, with 30 tablets per package. In conventional pharmaceutical formulations, sildenafil tablet strength is generally expressed as the sildenafil base equivalent rather than the mass of its citrate salt.

The package therefore represents 1,500 mg of stated sildenafil-equivalent content if the conventional strength convention applies.

The exact strength-expression convention and analytical content of the Biochem product require confirmation.

1. Selectively Inhibits Phosphodiesterase Type 5

Sildenafil inhibits PDE5 and slows the breakdown of cGMP.

This allows nitric oxide-mediated signaling to persist longer in responsive smooth muscle tissues.

2. Supports Erectile Function Through Increased Blood Flow

During sexual stimulation, nitric oxide release promotes cGMP production in penile erectile tissue.

Sildenafil enhances this process by slowing cGMP degradation, supporting smooth muscle relaxation and blood flow.

3. Has Established Applications in Erectile Dysfunction

Sildenafil is used in selected patients experiencing erectile dysfunction.

Treatment decisions depend on the underlying cause, cardiovascular health, medications, and clinical circumstances.

4. Has a Relatively Shorter Half-Life Than Tadalafil

Sildenafil has an elimination half-life of approximately four hours.

Its duration of effect is generally shorter than that of tadalafil, although individual responses vary.

5. Is Influenced by Food and Absorption Conditions

Sildenafil is absorbed following oral administration.

A high-fat meal can delay absorption and alter the time required to reach peak concentrations.

6. Undergoes Hepatic Metabolism

Sildenafil is metabolized primarily through CYP3A4, with CYP2C9 contributing to its metabolism.

The N-desmethyl metabolite retains some PDE5-inhibiting activity.

7. Requires Important Cardiovascular and Visual Safety Precautions

Sildenafil may cause headache, flushing, nasal congestion, indigestion, dizziness, and visual disturbances.

It must not be combined with nitrates or riociguat because dangerous reductions in blood pressure may occur.

Rare serious complications include sudden vision loss, sudden hearing loss, and prolonged erection requiring emergency treatment.

Step 1 – Oral Administration and Absorption

Sildenafil is absorbed through the gastrointestinal tract following oral administration.

Step 2 – Distribution to PDE5-Expressing Tissues

Sildenafil enters systemic circulation and reaches tissues containing PDE5.

Step 3 – Inhibition of cGMP Breakdown

Sildenafil inhibits PDE5, reducing degradation of cGMP.

Step 4 – Enhancement of Nitric Oxide-Mediated Smooth Muscle Relaxation

During sexual stimulation, enhanced cGMP signaling supports penile smooth muscle relaxation and blood flow.

Step 5 – Hepatic Metabolism and Elimination

Sildenafil undergoes hepatic metabolism, primarily through CYP3A4 and CYP2C9, followed by elimination mainly through fecal pathways.
