Penegra 100 mg belongs to the drug class known as phosphodiesterase type 5 (PDE5) inhibitors. It contains the active ingredient sildenafil citrate, which is commonly used in the treatment of erectile dysfunction (ED) in men.
PDE5 inhibitors work by affecting an enzyme called phosphodiesterase type 5, which regulates blood flow in certain tissues. By blocking this enzyme, sildenafil helps increase levels of a natural chemical called cyclic guanosine monophosphate (cGMP). This causes relaxation of smooth muscles in the blood vessels of the penis, allowing increased blood flow during sexual stimulation and supporting an erection.
PENEGRA 100 MG does not increase sexual desire and does not produce an erection without sexual arousal. It is usually taken as directed by a healthcare professional before sexual activity.
Other medicines in the PDE5 inhibitor class include tadalafil, vardenafil, and avanafil. Although they work in a similar way, they may differ in how quickly they start working and how long their effects last.
Penegra 100 mg should be used carefully, especially by men with heart conditions, low blood pressure, or those taking nitrate medications, as combining these medicines can cause a dangerous drop in blood pressure. A healthcare provider can determine whether sildenafil is appropriate based on an individual’s medical history and current medications.
