Virecta for the treatment of erectile dysfunction


Virecta film coated tablets


Each F.C. tablet contains:
Sildenafil (ascitrate) 100 mg


Virecta is a safe and effective oral treatment for erectile dysfunction (ED) in men. ED is the persistent inability to achieve or sustain an erection sufficient for sstisfactory sexual performance, a satisfactory treatment for this condition relies on the relaxation of the smooth muscles of the corpora carvemosa to facilitate erection. Sildenafil citrate is a selective inhibitor of type V phosphodiesterase (PDE5) that enhances the effect of nitric oxide (NO) which is released in the corpora in response to sexual stimulation. The release of NO stimulates the enzyme guanylate cyclase to produce cyclic GMP, which in turn relaxes arterial smooth muscle. Cyclic GMP is then broken down by PDE5. Sildenafil as a PDE5 inhibitor prevents the breakdown of cyclic GMP and
hence prolongs arterial relaxation and inflow of arterial blood and thereby enhances erection. Vi recta therefore causes erection only in the context of sexual stimulation.


For the treatment of erecti le dysfunction


-In patients with known hypersensitivity to sildenafil or any of the
components of the tablet
-In patients who are using organic nitrates, concomitant therapywith Virecta “may potentiate the  hypotensive effect of nitrates.
-Not indicated for use in newborn, children or women
-In patients with pre-existing cardiovascular disease and those having atrophy of the optical nerve and decreased visual field.
-Prolonged erection greater than 4 hours (painful erection greater than 6 hours in duration) the patient should seek immediate medical assistance .If priapism is not treated immediately ,penile tissue damage and permanent loss of potency could result.

Drug interactions:

-It is not recommended to use Virecta in combination with other treatments for erectile dysfunction
-Concomitant administration of the protease inhibitor ritonavir increases serum concentration of Sildenafil, also co- administration of the HlV protease inhibitor saquinavir increases the level of Sildenafil, caution should therefore be exercised in such patients.
-Co-administration of the potent cytochrome P450 3A4 inhibitors, Erythromycin, Ketoconazole and Itraconazole as wcll as the non specific CYP irthibitor Cirnetidine increases the plasma level of Sildenafil through reduction of its clearance.
-The CYP stimulant Rifampin decreases plasma level of Sildenafil

-Prc-existing cardiovascular disease such as angina, chest pain, heart failure, irregular heart beats, hypotension or hypertension
-Severe hepatic or renal impairment

impairment ,severe renal failure and age over 65 years old as a dose more than that may lead to increase in sildenafil serum level and so increase in both the efficacy and incidence of adverse effect.Overdosage The medication is stopped and standard supportive measures are to be immediately adopted.
