What It Is and How It Works
Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor. Its primary function is to facilitate the erection process in men with ED. PDE5 inhibitors work by blocking the degradation of cyclic guanosine monophosphate (cGMP), a molecule that facilitates the relaxation of smooth muscles in the penis and promotes increased blood flow. This mechanism ultimately supports the physiological process of achieving an erection following sexual stimulation.
Indications / Uses
Sildenafil citrate is mainly indicated for the treatment of erectile dysfunction. It helps men with ED to achieve and maintain an erection sufficient for sexual activity. While primarily a treatment for ED, researchers have explored other off-label uses, such as pulmonary arterial hypertension and certain circulatory disorders, though these should only be pursued under practitioner supervision.
Dosage Forms and Typical Dosing Considerations
Sildenafil is commonly available in oral tablet forms, ranging from 25 mg to 100 mg. The 200 mg dosage is less common and would generally be prescribed under special circumstances where a higher dose is deemed necessary and safe by a healthcare provider. Dosing adjustments may be required based on patient factors such as age, liver and kidney function, and interactions with other medications. Always follow the dosing instructions provided by your healthcare professional.
How to Take It Correctly Step-by-Step
To correctly take sildenafil citrate:
- Take the tablet approximately 30-60 minutes before anticipated sexual activity.
- It can be taken with or without food, but might take longer to work after a high-fat meal.
- Do not take more than once daily.
- Store at room temperature, away from moisture and heat.
- If you miss a scheduled dose, take it as soon as you remember if planning for sexual activity. Do not double doses.
