What It Is and How It Works
Sildenafil is classified as a phosphodiesterase type 5 (PDE5) inhibitor. It primarily facilitates the relaxation of blood vessels, promoting increased blood flow. The drug\’s action helps achieve and maintain an erection when used to treat erectile dysfunction by enhancing the natural erectile responses following sexual stimulation.
Indications / Uses
The primary approved use of Sildenafil is treating erectile dysfunction. Another significant use approved in many regions is for managing pulmonary arterial hypertension, where it helps by relaxing blood vessels in the lungs, reducing workload on the heart. Some off-label uses may exist but should only proceed under medical supervision.
Dosage Forms and Typical Dosing Considerations
Sildenafil, including its brand variant Cenforce, typically comes in tablet form available in various strengths. The standard dosing for erectile dysfunction is starting with a lower dose, depending on individual health factors, and adjusting as needed. Dosage for pulmonary arterial hypertension is typically more specific and requires adjustment according to condition severity, kidney and liver function, and possible drug interactions. Always adhere to the prescribed dosage and guidance from healthcare providers.
How to Take It Correctly Step-by-Step
