Modrasil (Sildenafil Citrate)

Sildenafil blocks phosphodiesterase type 5, an enzyme that degrades cGMP. By preserving cGMP, it promotes smooth‑muscle relaxation in the corpus cavernosum and pulmonary vessels, increasing blood flow and facilitating erection or lowering pulmonary arterial pressure.

The appropriate dose of Modrasil is determined by a qualified prescriber based on the patient’s condition, response, and any concomitant medications. Patients should follow the prescribing information provided by their healthcare professional.

The safety of sildenafil in pregnancy or while breastfeeding has not been established. It is generally not recommended for use in these populations unless a prescriber determines that the potential benefits outweigh the risks.

Modrasil (sildenafil) belongs to the phosphodiesterase type 5 inhibitor class, similar to drugs such as tadalafil and vardenafil. While all share a common mechanism, differences exist in onset of action, duration of effect and dosing flexibility, which clinicians consider when selecting therapy.

Modrasil should be stored at room temperature, below 25 °C, in its original packaging. Keep the tablets away from moisture, heat and direct sunlight to maintain product stability.

Modrasil is taken orally, usually with water, about 30 minutes to 1 hour before sexual activity or as directed for pulmonary hypertension. The tablet should be swallowed whole and not crushed or chewed.

Serious risks include priapism (a prolonged erection lasting more than four hours), severe hypotension especially when combined with nitrates, sudden hearing loss, and rare visual disturbances. Patients experiencing any of these should seek immediate medical attention.

Modrasil is contraindicated in patients taking nitrates, those with severe uncontrolled hypertension, recent myocardial infarction, severe hepatic impairment, or known hypersensitivity to sildenafil or any tablet excipients.
