Vilitra 20 (Vardenafil 20 mg) – Product Description

Product Overview

Vilitra 20 is a pharmaceutical preparation containing Vardenafil 20 mg as its active substance, manufactured by Centurion Laboratories. Vardenafil is a highly selective phosphodiesterase type 5 (PDE5) inhibitor indicated for the treatment of erectile dysfunction (ED) in adult men. As a PDE5 inhibitor, Vardenafil works by increasing blood flow to the penis through the relaxation of smooth muscle in penile blood vessels, facilitating the achievement and maintenance of an erection sufficient for satisfactory sexual performance when combined with sexual stimulation.

Vilitra 20 is a generic equivalent to the branded reference product Levitra, which received initial U.S. Food and Drug Administration approval in 2003. Clinical studies have demonstrated that Vardenafil 20 mg produces significant improvements in erectile function across a broad range of patient populations, regardless of age, baseline severity, or underlying etiology.

Mechanism of Action

Vardenafil selectively inhibits phosphodiesterase type 5 (PDE5), an enzyme responsible for the hydrolysis of cyclic guanosine monophosphate (cGMP) in the corpus cavernosum tissue of the penis. By inhibiting PDE5, Vardenafil increases intracellular cGMP levels, which leads to smooth muscle relaxation, enhanced arterial blood flow, and subsequent engorgement of the corpus cavernosum. This physiological response results in penile tumescence and erection. The medication is effective only in the presence of sexual stimulation.

Clinical Efficacy

Clinical research substantiates the efficacy of Vardenafil 20 mg in treating erectile dysfunction:

• In a 26-week trial involving 736 men with ED of varied etiologies and severity, 85% of Vardenafil 20 mg recipients reported improved erectile function compared with 28% of placebo recipients.

• Vardenafil 20 mg demonstrated a high first-dose success rate, with 81% success for penetration (SEP2) and 70% for maintenance of erection (SEP3), with these rates maintained through the study endpoint (85% for SEP2 and 78% for SEP3).

• Vardenafil has demonstrated sustained long-term efficacy, providing up to 92% of patients with improved erections over more than 2 years of treatment.

• The medication has proven efficacious in challenging patient populations, including those with diabetes mellitus and post-radical prostatectomy patients.

• Vardenafil has a rapid onset of action, with erections sufficiently rigid for intercourse completion achievable as early as 16 minutes after ingestion.

Dosage and Administration

The recommended starting dose of Vardenafil is 10 mg, taken orally as needed approximately 25 to 60 minutes before sexual activity. Based on individual efficacy and tolerability, the dose may be increased to a maximum of 20 mg or decreased to 5 mg. The maximum recommended dosing frequency is one tablet per day. Vilitra 20 may be taken with or without food, though the onset of activity may be delayed if taken with a high-fat meal.
