Sildenafil 20 mg oral tablet

Need reliable information on Sildenafil 20mg oral tablets? Focus on understanding its purpose: treating erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). This concise guide provides practical details to help you make informed decisions regarding this medication.

Sildenafil 20mg works by increasing blood flow to specific areas of the body. For ED, this improves erectile function. In PAH, it relaxes blood vessels in the lungs, improving blood flow and reducing strain on the heart. Dosage is crucial; always adhere strictly to your doctor’s prescription. Never adjust the dosage without medical consultation.

Potential side effects include headache, flushing, nasal congestion, and visual disturbances. Serious side effects are rare but require immediate medical attention. These include chest pain, sudden vision loss, or prolonged erection (priapism). Consult your physician if you experience any unusual symptoms.

Before starting Sildenafil, discuss your medical history with your doctor, including any existing heart conditions, liver or kidney problems, or other medications you’re taking. This ensures safe and effective use and minimizes potential interactions. Remember: This information is for educational purposes and doesn’t replace professional medical advice.

Understanding Sildenafil’s Mechanism of Action

Sildenafil works by inhibiting a specific enzyme called phosphodiesterase-5 (PDE5). This enzyme breaks down cyclic guanosine monophosphate (cGMP), a crucial molecule for penile erection.

By blocking PDE5, sildenafil allows cGMP levels to rise. Increased cGMP relaxes the smooth muscles in the blood vessels of the penis, leading to increased blood flow.

This increased blood flow is the key to achieving and maintaining an erection. The process is triggered by sexual stimulation, which initiates the release of nitric oxide, further boosting cGMP production and enhancing the effect of sildenafil.

Step	Process
1	Sexual stimulation releases nitric oxide.
2	Nitric oxide increases cGMP levels.
3	Sildenafil inhibits PDE5, preventing cGMP breakdown.
4	Elevated cGMP relaxes penile blood vessels.
5	Increased blood flow produces an erection.

It’s important to note that sildenafil only works in the presence of sexual stimulation; it doesn’t create spontaneous erections.
