Abstract
Abstract A nondepolarizing muscle relaxant containing, as active principle ingredient, p,p"-bis-triethylammonio-n-terphenyl dibenzenesulphonate in a pharmaceutical carrier is described. The proposed preparation is used as a 0.5 per cent aqueous solution. Said muscle relaxant possesses high potency and selectivity. When given in a myoparalytic dose, it does not affect the arterial pressure. The preparation is nontoxic, its effect is quickly and fully removed by cholinesterase inhibitors, which ensures higher safety and better control of muscle relaxation compared with the action of the known muscle relaxants α-tubocurarin and pancuronium.
