Kamagra Polo is primarily prescribed to treat erectile dysfunction, a condition where men have difficulty achieving or maintaining an erection sufficient for sexual activity. Sildenafil citrate in Kamagra Polo works similarly to other PDE5 inhibitors. It inhibits the enzyme PDE5, leading to increased levels of cyclic guanosine monophosphate (cGMP) in the body. This promotes relaxation of smooth muscles and dilation of blood vessels in the penis, allowing for improved blood flow. Sexual stimulation is still required to trigger the erection.
