Libidus

Libidus was marketed as a "natural" dietary supplement for the treatment of erectile dysfunction and sexual enhancement. However, regulatory investigations by the FDA and Health Canada revealed that the product contained undeclared pharmaceutical ingredients, specifically **acetildenafil** (a synthetic analogue of sildenafil) and a modified form of **vardenafil**. These substances are potent phosphodiesterase-5 (PDE5) inhibitors. The presence of these undeclared drugs posed significant health risks, particularly the potential for life-threatening hypotension when combined with nitrates. As a result, Libidus was classified as a misbranded and unapproved new drug, and its importation and sale were banned in several jurisdictions. It was never part of a legitimate pharmaceutical development program and its manufacturer remains unknown.
