What It Is and How It Works

Sildenafil citrate is a medication classified as a phosphodiesterase type 5 (PDE5) inhibitor. It works by inhibiting the PDE5 enzyme in the body, which leads to an increase in cyclic guanosine monophosphate (cGMP). This biochemical change relaxes the smooth muscles and dilates blood vessels in the penis, allowing more blood flow during sexual arousal, which facilitates an erection.

Indications / Uses

The primary approved use of sildenafil citrate tablets is to treat erectile dysfunction in men. It helps men achieve an erection when sexually stimulated but does not cause an erection without stimulation. It is also sometimes used off-label for other conditions, such as pulmonary arterial hypertension, under medical supervision.

Sildenafil citrate is commonly available in tablet form with varying dosages: 25mg, 50mg, and 100mg. The 100mg dosage is often prescribed for those who do not achieve adequate results with lower doses. However, the exact dosage will depend on individual factors like health status, age, and concurrent medications.

Patients with liver or kidney disease, senior adults, or those taking interacting medications may require dosage adjustments. It is vital to follow the healthcare provider\’s instructions and not exceed the recommended dose.

How to Take It Correctly Step-by-Step
