What It Is and How It Works
Sildenafil citrate operates primarily as a phosphodiesterase type 5 (PDE5) inhibitor. By blocking this enzyme, it allows the blood vessels to relax and widen, particularly in the penis, which enhances blood flow. This mechanism aids in achieving and maintaining an erection when there is sexual stimulation. In the context of pulmonary arterial hypertension, sildenafil also helps relax blood vessels in the lungs, reducing blood pressure and improving cardiac output.
Indications / Uses
Sildenafil citrate is primarily indicated for the treatment of erectile dysfunction in men. It may also be prescribed for the management of pulmonary arterial hypertension under different brand names and formulations. The medication is beneficial for individuals experiencing ED due to vascular or neurological causes, provided they do not have contraindications such as a history of stroke or heart conditions.
Dosage Forms and Typical Dosing Considerations
Sildenafil citrate is typically available in tablet form, with common doses ranging from 25 mg to 100 mg depending on the individual\’s needs and doctor\’s prescription. The timing of dosing is crucial; it is often recommended to take it about an hour before sexual activity. Dosing may need adjustment based on factors like liver function, kidney function, and other medications. Patients must follow their specific prescription instructions.
