Quick Facts

What It Is and How It Works
Viagra, whose active ingredient is sildenafil citrate, belongs to a class of medications called PDE5 inhibitors. It operates by blocking the enzyme phosphodiesterase type 5 (PDE5) in the smooth muscle cells lining the blood vessels in the penis. This action leads to an increase in cyclic guanosine monophosphate (cGMP), causing relaxation of the smooth muscles and increased blood flow to the penis, facilitating an erection in response to sexual stimulation.
Indications / Uses
Viagra is primarily prescribed for the treatment of erectile dysfunction, helping men achieve and maintain an erection sufficient for sexual activity. It is most effective when combined with sexual stimulation. Off-label uses are not commonly recognized and should only be pursued under a healthcare provider\’s supervision.
Dosage Forms and Typical Dosing Considerations
Viagra is available in tablet form, typically in doses of 25 mg, 50 mg, and 100 mg. The maximum recommended dose for most adults is 100 mg per day. In exceptional clinical scenarios, a healthcare provider may prescribe higher doses, such as 200 mg, if deemed necessary and safe. Factors influencing dosing include the patient’s overall health, concurrent medical conditions, and responses to treatment. Older adults or individuals with kidney or liver impairments often require adjusted doses.
How to Take It Correctly Step-by-Step
- Take the tablet approximately 30 to 60 minutes before sexual activity.
- Swallow with water, with or without food.
