Uses of Tadalafil (the salt in Forzest 20)

• Erectile Dysfunction (ED): A condition where men have difficulty achieving or maintaining an erection during sexual activity, even when sexually stimulated. Forzest 20 helps relax the veins and arteries in the penis, facilitating a strong erection during sexual activity.

• Pulmonary Arterial Hypertension (PAH): A condition where the blood pressure in the arteries of the lungs is raised. Forzest 20 works by relaxing the blood vessels in the lungs, lowering the blood pressure.

• Benign Prostatic Hyperplasia (BPH): An enlarged prostate condition. Forzest 20 helps improve blood flow to the prostate, relaxing muscles in the prostate and bladder, thus relieving urinary symptoms.
  Typically, a higher dose is used for treating Pulmonary Arterial Hypertension compared to ED and BPH.

How Forzest 20 Works
Forzest 20, containing Tadalafil, works by inhibiting Phosphodiesterase Type 5 (PDE-5) in the body. This prevents the breakdown of Cyclic Guanosine Monophosphate (cGMP), which relaxes the blood vessels in the penis, aiding in an erection when there is sexual stimulation.
It also helps relax the smooth muscles of pulmonary blood vessels, aiding in the reduction of pressure in the lungs.
