What is Penegra 100mg Sildenafil?
Penegra 100mg Sildenafil is a medication primarily used to address erectile dysfunction (ED) in men, a condition marked by the inability to achieve or sustain an erection during sexual activity. This medication contains sildenafil citrate as its active ingredient, which belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. These inhibitors work by enhancing blood flow to the penile region, aiding in the achievement and maintenance of an erection when sexually stimulated.
The mechanism of action of Penegra 100mg involves inhibiting the enzyme phosphodiesterase type 5 (PDE5) in the corpus cavernosum of the penis. When a man is sexually stimulated, nitric oxide (NO) is released into the erectile tissue, leading to the synthesis of cyclic guanosine monophosphate (cGMP). cGMP is responsible for relaxing the smooth muscles of the penile blood vessels, allowing increased blood flow into the penis and resulting in an erection. However, PDE5 breaks down cGMP, leading to a decrease in its levels and the termination of the erection. By inhibiting PDE5, sildenafil prolongs the action of cGMP, maintaining the relaxation of smooth muscles and the erection.
Penegra 100mg Sildenafil is typically taken orally, with a recommended dosage of one 100mg tablet per day. It should be ingested approximately 30 minutes to 1 hour before anticipated sexual activity, although the onset of action can vary among individuals. It’s important to note that Penegra 100mg does not induce automatic erections; sexual stimulation is still necessary for the medication to be effective.
