Sildenafil, the active compound in Manforce 100 mg, is a phosphodiesterase type 5 (PDE5) inhibitor. It inhibits and slows down the adverse effects of PDE 5 on cGMP. CGMP is crucial for increasing blood flow into the male genital and organ to cause erection.
When your body feels sexual stimulation, it releases nitric oxide. During sexual arousal, our body releases nitric oxide (NO) into the erectile tissue. NO stimulates an enzyme called Guanylate Cyclase, increasing cyclic guanosine monophosphate (cGMP) levels. CGMP relaxes the smooth muscles in the blood vessels of the penis, allowing them to dilate. Dilated blood vessels improve blood flow to the corpus cavernosum (the spongy tissues in the penis), leading to an erection.
Sildenafil, the active ingredient in Manforce 100 mg, blocks the enzyme phosphodiesterase type 5 (PDE5), which breaks down cGMP. By inhibiting PDE5, sildenafil maintains higher cGMP levels, prolonging the erection.
Manforce 100mg takes about 30-60 minutes to work. It is optimal when taken on an empty stomach. Effects last 4-6 hours, although this varies between individuals. It does not affect libido or sexual desire.
