What It Is and How It Works
Sildenafil citrate is an oral phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a molecule that helps relax blood vessels. By inhibiting PDE5, sildenafil citrate increases the level of cGMP, facilitating increased blood flow to the penis during sexual arousal, which helps to achieve and maintain an erection sufficient for sexual activity.
Indications / Uses
The primary indication for sildenafil citrate is the treatment of erectile dysfunction in men. In some cases, it may be prescribed off-label to treat pulmonary arterial hypertension (PAH), a different medical condition involving high blood pressure in the arteries of the lungs, although this is typically under the supervision of a healthcare professional.
Dosage Forms and Typical Dosing Considerations
Sildenafil citrate is available in the form of oral tablets, commonly in doses of 25 mg, 50 mg, and 100 mg. The initial dose may vary based on individual health factors, and adjustments may be made depending on effectiveness and tolerability. It is typically taken as needed, approximately one hour before sexual activity, but its dosing may be influenced by factors such as age, liver and kidney function, and concurrent medications.
How to Take It Correctly Step-by-Step
To take sildenafil citrate effectively, follow these steps:
- Timing: Take the medication about 30 to 60 minutes before planned sexual activity.
- Food Intake: It can be taken with or without food, although a high-fat meal may delay its onset of action.
- Missed Dose: Since it is taken as needed, there is no strict dosing schedule. Do not take more than once daily.
- Storage: Store at room temperature away from moisture and heat.
