Viagra (Sildenafil Citrate) 100 mg – 30 Tablets

Biochem Viagra (Sildenafil Citrate) 100 mg – 30 Tablets | Oral PDE5 Inhibitor

Biochem Viagra (Sildenafil Citrate) 100 mg – 30 Tablets is an oral pharmaceutical product. This product contains sildenafil citrate, a selective phosphodiesterase type 5 inhibitor associated with the treatment of erectile dysfunction.

Sildenafil is a well-established member of the PDE5 inhibitor class and is commercially associated with the pharmaceutical brand name Viagra.

Its principal pharmacological mechanism involves inhibition of phosphodiesterase type 5, an enzyme responsible for breaking down cyclic guanosine monophosphate (cGMP).

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

Sildenafil slows cGMP degradation, enhancing smooth muscle relaxation and supporting increased penile blood flow.

Sildenafil does not independently produce an erection without sexual stimulation.

The compound has an approximate elimination half-life of four hours and undergoes extensive hepatic metabolism.

Sildenafil also has established applications in pulmonary arterial hypertension under separate pharmaceutical indications.

The 100 mg strength is the highest conventional Viagra tablet strength for erectile dysfunction in many jurisdictions. It is not appropriate for every patient, and higher strength does not guarantee a better clinical response.

Adverse effects and drug interactions are important considerations when evaluating sildenafil exposure.

Biochem Viagra 100 mg contains sildenafil citrate in an amount corresponding to the stated 100 mg tablet strength, with 30 tablets per package. In conventional pharmaceutical formulations, sildenafil strength is generally expressed as sildenafil base equivalent.

The package therefore represents 3,000 mg (3 grams) 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 degradation of cGMP.

This enhances nitric oxide-mediated signaling in responsive smooth muscle tissues.

2. Supports Erectile Function Through Smooth Muscle Relaxation

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

Sildenafil enhances this process by reducing cGMP breakdown and supporting increased blood flow.

3. Has Established Applications in Erectile Dysfunction

Sildenafil is used in selected patients experiencing erectile dysfunction.

The appropriate treatment depends on the underlying cause, cardiovascular status, concurrent medications, and clinical evaluation.

4. Has an Approximate Four-Hour Elimination Half-Life

Sildenafil has a relatively shorter elimination half-life than tadalafil.

Its duration of effect varies among individuals and does not indicate continuous erection.

5. Is Influenced by Food and Absorption Conditions

Sildenafil is absorbed following oral administration.

High-fat meals can delay absorption and alter the time required to reach peak concentrations.

6. Undergoes CYP3A4- and CYP2C9-Mediated Metabolism

Sildenafil undergoes hepatic metabolism, primarily involving CYP3A4 and CYP2C9.

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

7. Requires Particular Attention to Dose-Related Adverse Effects

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

The 100 mg strength can increase exposure-related adverse effects compared with lower strengths.

Sildenafil must not be combined with nitrates or riociguat. Rare serious complications include sudden vision or hearing loss and prolonged erection requiring emergency medical attention.

The 100 mg strength is not suitable for every patient. It should not be assumed to be safer or more effective than the 50 mg strength for an individual patient.

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 and reduces degradation of cGMP.

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

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

Step 5 – Hepatic Metabolism and Elimination

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