Levitra is a medication used to treat erectile dysfunction in men. It works by relaxing the blood vessels in the penis, allowing for increased blood flow and improved ability to achieve and maintain an erection during sexual activity. It should only be taken as directed by a healthcare professional.
Levitra works by inhibiting the action of an enzyme called phosphodiesterase type 5 (PDE5) which breaks down a chemical called cyclic guanosine monophosphate (cGMP) in the penis. This leads to relaxation of the smooth muscle tissue and dilation of the blood vessels, allowing for increased blood flow to the penis and improved ability to achieve and maintain an erection during sexual stimulation.
Levitra is available in tablet form in different dosages, including 2.5 mg, 5 mg, 10 mg, and 20 mg. The usual recommended starting dose for most men is 10 mg, which should be taken 30-60 minutes before sexual activity. Depending on the individual's response and tolerance, the dose may be adjusted up to a maximum of 20 mg or down to a minimum of 2.5 mg. It is important to follow the dosage instructions provided by a healthcare professional and not to exceed the recommended dose.
