What It Is and How It Works
Sildenafil functions as a phosphodiesterase type 5 (PDE5) inhibitor. It enhances erectile function by inhibiting the enzyme PDE5, which regulates blood flow in the penis. The inhibition leads to increased levels of cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penis, promoting relaxation and allowing blood to flow in, resulting in an erection during sexual stimulation.
Indications / Uses
The primary approved use of sildenafil is the treatment of erectile dysfunction. It is a condition characterized by difficulty in achieving or maintaining an erection suitable for sexual intercourse. There is occasional off-label use for pulmonary arterial hypertension, but such uses should be directed by a physician.
Dosage Forms and Typical Dosing Considerations
Sildenafil is most commonly available in tablet form with varying strengths of 25mg, 50mg, and 100mg. It is crucial to note that 200mg is not a standard prescribed dose for most individuals. Dosage must be determined by a healthcare professional based on the patient\’s health status and response to treatment. Factors such as age, kidney and liver function, and concurrent medications can influence dosing.
How to Take It Correctly Step-by-Step
- Take sildenafil as prescribed by your healthcare provider, typically one hour before sexual activity.
- Swallow the tablet whole with water, with or without food.
- Do not exceed one dose per day.
- If a dose is missed for planned sexual activity, take it as soon as remembered. Do not double the dose to make up for a missed one.
