Modula 5 Mg contains Tadalafil which belongs to the group of medicines called Phosphodiesterase type 5 (PDE 5) inhibitors. It is used in adult men to treat erectile dysfunction and urinary symptoms associated with benign prostatic hyperplasia (prostate enlargement causing painful or frequent urination or untentional passing of urine). Erectile dysfunction (also known as impotence) is a sexual condition where a man cannot sustain a hard erected penis that is required for a normal sexual activity. It happens due to decreased blood flow to the penis. Modula 5 Mg would help you to get an erection only if you are sexually stimulated. It is not an aphrodisiac (sex-stimulating agent) and therefore cannot be used to induce sexual thoughts or can improve sexual performance/pleasure in healthy men. It is also not suitable for use in healthy men who do not have erectile dysfunction.
