True about d–TC is all except – a) Excreted unchanged by kidneyb) Causes hypotension by ganglion blocking actionc) Vagolytic actiond) Effects lasts for 2–3 hours

D-tubocurarine has maximum ganglion blockade and histamine releasing propensity → Can cause hypotension. It does not have vagolytic action (non-depolarizing blocker causing vagal block are Pancuronium, Gallamine and Rocuronium). Duration of action is around 80 minutes. d-TC is primarily excreted by kidney.
