 Use of RX 67668


RX 67668 is a potent cholinesterase inhibitor with an IC50 of 5 μM for both acetylcholinesterase (AChE) and butyrylcholinesterase. RX 67668 can reverse the neuromuscular blockade induced by D-tubocurarine. RX 67668 is a muscle relaxant used to relieve skeletal muscle fatigue[1][2].

In Vivo RX 67668 (1-4 mg/kg; i.p.) reduces by half the dose of methacholine necessary to produce red tears, whilst RX 67668 (7-2 mg/kg s.c.) is necessary to reduce the pupil diameter of the mouse to 50% of the control value[1]. Rat anterior tibialis preparation of the cat tibialis preparation demonstrates that RX 67668 (0.3-1.0 mg/kg; i.v.) is effective in reversing tubocurarine-induced muscle blockade[1].
