Levitra is indicated for the treatment of erectile dysfunction in adult men, a condition characterized by the inability to get or keep an erection firm enough for sexual activity.
Levitra works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which normally breaks down a substance called cyclic guanosine monophosphate (cGMP). By blocking PDE5, Levitra allows cGMP to accumulate, promoting relaxation of smooth muscles and increased blood flow to the penis during sexual stimulation.
Levitra does not protect against sexually transmitted diseases or serve as a form of contraception. It requires sexual stimulation to work and should not be used with nitrates or certain other medications. Patients should consult their healthcare provider for appropriate dosing and to discuss potential side effects and contraindications.
