How Levitra Works
Levitra belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors. It helps to relax the blood vessels in the penis, which increases blood flow and facilitates an erection when there is sexual stimulation. Here are key points detailing how it works:
- Inhibition of PDE5 enzyme: Levitra blocks the action of the PDE5 enzyme, allowing for increased levels of cyclic guanosine monophosphate (cGMP).
- Relaxation of blood vessels: Higher cGMP levels lead to relaxation of smooth muscles in the blood vessels, enhancing blood flow to the penis.
- Erection achievement and maintenance: Improved blood flow helps men to achieve and sustain an erection suitable for sexual activity.
Dosage and Administration
The recommended starting dose of Levitra is usually 10 mg, taken about 60 minutes before anticipated sexual activity. Depending on efficacy and tolerance, the dose may be adjusted upwards to a maximum of 20 mg or downwards to 5 mg. It is important to note that Levitra should not be taken more than once daily.
Side Effects and Precautions
Like any medication, Levitra may cause side effects. Common side effects include:
- Headache
- Flushing
- Nasal congestion
- Dizziness
- Digestive issues
Men who have certain medical conditions or are taking specific medications should consult with a doctor before using Levitra to avoid potential drug interactions.
