What is Viagra?
Viagra, a well-known pharmaceutical drug, is primarily used to treat erectile dysfunction (ED) in men. Originally introduced by Pfizer in 1998, it has since become synonymous with ED treatment. The active ingredient in Viagra is sildenafil citrate, which works by enhancing blood flow to the penis, enabling a man to achieve and maintain an erection during sexual stimulation.
How Viagra Works: The Mechanism
Viagra functions by inhibiting phosphodiesterase type 5 (PDE5), an enzyme that breaks down cyclic guanosine monophosphate (cGMP). cGMP is responsible for relaxing smooth muscles and increasing blood flow to the penile area. By blocking PDE5, Viagra maintains higher levels of cGMP, thus facilitating an erection in response to sexual arousal.
Indications for Use
Viagra is prescribed for the treatment of erectile dysfunction, a common condition affecting millions of men worldwide. It is essential to note that Viagra does not cure ED or increase sexual desire. It is effective only when there is sexual stimulation.
How to Use Viagra
Recommended Dosage
The typical starting dose of Viagra is 50 mg, taken approximately one hour before sexual activity. However, it can be taken anywhere from 30 minutes to four hours before intercourse. Depending on efficacy and tolerance, the dose may be adjusted to a maximum of 100 mg or reduced to 25 mg. It should not be taken more than once a day.
Administration Guidelines
– Take with water: Swallow the tablet with a glass of water.
– Avoid high-fat meals: Consuming Viagra with a high-fat meal may delay its absorption and effect.
– Limit alcohol consumption: Excessive alcohol can impair the ability to achieve an erection and may increase the risk of side effects.
Possible Side Effects of Viagra
Like all medications, Viagra can cause side effects. Some common side effects include:
– Headache
– Flushing
– Indigestion
– Nasal congestion
– Dizziness
Less common but more severe side effects may include:
– Sudden vision loss

– Priapism (prolonged and painful erection)
If you experience any severe side effects, it is crucial to seek medical attention immediately.
