1. Vardenafil's indications and contra-indications are the same as with other PDE5 inhibitors; it is closely
related in function to sildenafil citrate (Viagra) and tadalafil (Cialis). Sildenafil Citrate is solely active in
relaxing muscles and increasing blood flow to the heart, lungs and penis due to PDE-5, yet vasodilation is
not increased in other parts of the body.
2. Sildenafil is used to treat high blood pressure in the lungs (pulmonary hypertension). It works by
relaxing and widening the blood vessels in your lungs which allows the blood to flow more easily.
Decreasing high blood pressure in the lungs allows your heart and lungs to work better and improves your
ability to exercise.

Sildenafil citrate, sold as Viagra, Revatio and under various other trade names, is a drug used to treat
erectile dysfunction and pulmonary arterial hypertension (PAH).
tadalafil's pharmacologic distinction is its longer half-life (17.50 hours) – compared to sildenafil (4.0–5.0
hours) and vardenafil (4.0–5.0 hours) – resulting in longer duration of action, and so partly responsible
for "The Weekend Pill" sobriquet. Furthermore, the longer half-life is the basis for current investigation of
tadalafil's daily therapeutic use in relieving pulmonary arterial hypertension. Sildenafil is approved in
several world regions as a thrice-daily therapy for pulmonary arterial hypertension.
Sildenafil citrate 50 mg is the recommended starting dose for men with erectile dysfunction (ED); however,
most men are later titrated to sildenafil 100 mg for improved efficacy.
1) Sexual dysfunction:
The primary indication of sildenafil is treatment of erectile dysfunction (inability to sustain a satisfactory
erection to complete intercourse). Its use is now one of the standard treatment for erectile dysfunction,
ncluding for men with diabetes mellitus.
2) Pulmonary hypertension:
While sildenafil improves some markers of disease in people with pulmonary arterial hypertension, it does
not appear to affect the risk of death or serious side effects as of 2014.
3) Antidepressant-associated sexual dysfunction:
Tentative evidence suggests that sildenafil may help men who experience antidepressant-induced erectile
4) Altitude sickness:
Sildenafil appears to improve some risk factors for high-altitude pulmonary edema but it is unclear
whether or not it affects the rate of the condition itself.
