Vardenafil is a medication used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). It works by increasing blood flow to the penis, aiding in achieving and maintaining an erection. For PAH, it improves blood flow to the lungs.
Understanding Vardenafil’s Mechanism
Vardenafil belongs to a class of drugs called phosphodiesterase-5 (PDE5) inhibitors. These inhibitors block the action of PDE5, an enzyme that breaks down a substance called cyclic guanosine monophosphate (cGMP). Increased cGMP levels relax blood vessels, leading to improved blood flow.
- Erectile Dysfunction: Vardenafil facilitates penile engorgement in response to sexual stimulation. Pulmonary Arterial Hypertension: Vardenafil dilates pulmonary arteries, reducing blood pressure in the lungs.
Dosage and Administration
Dosage varies based on individual needs and the condition being treated. Always follow your doctor’s instructions precisely. Common side effects include headache, flushing, nasal congestion, and indigestion. Serious side effects are rare but require immediate medical attention.
Your doctor will determine the appropriate dosage and frequency. Take Vardenafil as directed, usually about an hour before sexual activity (for ED). Do not exceed the prescribed dose. Inform your doctor of any existing medical conditions or medications you are taking.
Consult your physician or pharmacist for detailed information regarding potential drug interactions and contraindications. They can provide personalized guidance and address any concerns you may have.
