Drug intelligence / Profile preview
Zertane-ED is a patented oral combination drug developed to treat men with both premature ejaculation (PE) and erectile dysfunction (ED). It combines the active ingredient of Zertane, tramadol hydrochloride, which is repurposed for the treatment of PE, with a phosphodiesterase type 5 (PDE5) inhibitor used for ED. The rationale behind this combination is that comorbidity between PE and ED is common in men. Tramadol acts as a centrally acting analgesic that can delay ejaculation by modulating neurotransmitter activity in the central nervous system. The PDE5 inhibitor component—though not specified by name in available sources—is likely sildenafil or another agent from this class, which works by enhancing nitric oxide–mediated vasodilation through inhibition of PDE5, thereby improving erectile function. This dual-action approach aims to address both conditions simultaneously[1][2][4].
