Viagra, or sildenafil, primarily works by inhibiting a specific enzyme called phosphodiesterase-5 (PDE5). This enzyme breaks down cyclic guanosine monophosphate (cGMP), a crucial molecule involved in the relaxation of smooth muscles in the penis.
By blocking PDE5, Viagra increases cGMP levels. Higher cGMP levels lead to increased blood flow into the penis, resulting in an erection. This process requires sexual stimulation; Viagra doesn’t cause erections spontaneously.
The impact of Viagra varies among individuals, depending on factors like age, overall health, and the presence of other medical conditions. Always consult your doctor before using Viagra to ensure it’s safe for you and to discuss potential side effects.
Specific dosage instructions should be followed carefully. Incorrect dosage could lead to reduced effectiveness or potential side effects. Always seek professional medical advice for any concerns regarding medication.
While Viagra is highly effective for many men with erectile dysfunction, it’s not a universal solution. Other underlying health issues may require further investigation and treatment.
