What It Is and How It Works
Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor, which aids in treating erectile dysfunction by allowing increased blood flow to the penile region. It works by binding to PDE5, an enzyme that plays a role in regulating blood flow in the penis. By inhibiting PDE5, sildenafil promotes the accumulation of cyclic guanosine monophosphate (cGMP), leading to relaxation of smooth muscles and increased blood flow upon sexual stimulation.
Indications / Uses
The primary indication for sildenafil citrate is the treatment of erectile dysfunction. It is generally prescribed for men who are unable to achieve or sustain an erection suitable for satisfactory sexual performance. Sometimes, sildenafil is used off-label for pulmonary arterial hypertension (PAH) under the supervision of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Sildenafil is available in various dosages, including 25 mg, 50 mg, and 100 mg tablets. The 200 mg dose is usually considered a higher range and should only be used under careful medical supervision when lower doses are ineffective. The medication\’s effects can be influenced by factors such as age, existing renal or liver conditions, and concurrent medications.
It is essential to follow the dosage as prescribed on the prescription label, not exceed the recommended dose, and use the medication as directed by a healthcare professional.
How to Take It Correctly Step-by-Step
Taking sildenafil correctly ensures its effectiveness and minimizes risks:
- Take the tablet approximately 30-60 minutes before planned sexual activity.
