Vamicamide

Vamicamide, also known as FK-176 or Urocut, is a muscarinic acetylcholine receptor (mAChR) antagonist that was developed by Fujisawa (now part of Astellas Pharma) for the treatment of urinary incontinence and overactive bladder.^[1] This small molecule drug acts by blocking muscarinic receptors, which play a role in bladder function. Despite showing promise in preclinical studies for increasing bladder capacity without affecting other urinary parameters,^[2] vamicamide has never been approved for medical use. The drug's development was ultimately discontinued, with its highest research and development status reaching the New Drug Application (NDA) phase in Japan.^[1]
