Hiforce 150mg contains Sildenafil Citrate 150mg. Sildenafil is a phosphodiesterase type-5 (PDE5) inhibitor.

During sexual stimulation, nitric oxide signaling increases cyclic GMP (cGMP) in penile tissue. Sildenafil inhibits PDE5, reducing cGMP breakdown and supporting smooth-muscle relaxation and penile blood flow.

Sildenafil does not directly increase sexual desire and does not produce an erection without sexual stimulation.

Because the listed strength of 150mg exceeds the usual maximum recommended single dose, this product requires particular attention to dosing and medical supervision.

How Sildenafil Citrate Works

Sildenafil selectively inhibits phosphodiesterase type-5 (PDE5).

The erectile response involves:

Sexual stimulation → nitric oxide release → increased cGMP → smooth-muscle relaxation → increased penile blood flow → erection

Sildenafil helps maintain cGMP activity by reducing its breakdown.

Sexual stimulation is required for sildenafil to work.
