Cenforce 130 mg is marketed as a sildenafil-based treatment for erectile dysfunction (ED). Sildenafil belongs to the phosphodiesterase type 5 (PDE5) inhibitor class and works by increasing blood flow to the penis during sexual stimulation. However, individual responses to sildenafil can differ significantly. Some men may experience improved ability to achieve or maintain an erection, while others may have limited benefits or experience side effects. Factors such as cardiovascular health, diabetes, age, stress, anxiety, sleep quality, alcohol consumption, and other medicines can influence how someone responds.
