Viamax 100

Generic

Sildenafil Citrate

Indication

The drug sildenafil is used to treat erectile dysfunction.

Pharmacology

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor that targets cyclic Guanosine Monophosphate (cGMP). It is used to treat erectile dysfunction. Danafil (Sildenafil) increases the effect of nitric oxide (NO) by blocking phosphodiesterase type 5 (PDE5), which is responsible for the breakdown of cGMP in the corpus cavernosum, which causes smooth muscle relaxation and blood inflow.

Dosage & Administration

The recommended dose of Sildenafil is 50 mg taken approximately 1 hour before sexual activity. However, Sildenafil may be taken anywhere from half an hour to 4 hours before sexual activity. Based on effectiveness and toleration, the dose may be increased to a maximum 100 mg or decreased to 25 mg. The maximum recommended dosing frequency is once per day.

Sildenafil may takes longer time to work if you take it with a heavy meal.

Interaction

When Sildenafil is taken with organic nitrates for angina, it can cause hypotension. Cimetidine, a drug used to treat gastric ulcers, as well as certain antibiotics like Erythromycin and Rifampicin, and protease inhibitors like Ritonavir and Saquinavir used to treat HIV infection, may raise Sildenafil levels in the blood. Ketoconazole and Itraconazole, both of which are used to treat fungal infections, may impair Sildenafil clearance.

Contraindications

Any component of sildenafil is contraindicated in patients who are hypersensitive to it. Sildenafil enhances the hypotensive effects of nitrates, hence it's not recommended for people who take organic nitrates on a regular or irregular basis.

 Side Effects

Headache, flushing, dyspepsia, nasal congestion, urinary tract infection, altered eyesight, diarrhea, dizziness, and rash are all side effects of Sildenafil.

 Pregnancy and Lactation

Category B pregnancy. Sildenafil has not been studied in pregnant women in a sufficient and well-controlled manner. Sildenafil is not recommended for women. Sildenafil has been shown to be teratogenic and embryotoxic in animal studies.
