Malegra 25 mg works by inhibiting the enzyme phosphodiesterase type 5 (PDE5). This enzyme restricts blood flow to the penis, making it difficult for men to achieve an erection. By blocking PDE5, Malegra 25 mg promotes the action of nitric oxide, which relaxes the blood vessels in the penis, allowing for increased blood flow. This effect helps men with ED obtain and sustain an erection during sexual stimulation.
