title: [Antigenicity study of (+/-)-4-diethylamino-1,1-dimethylbut-2-yn-1-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate monohydrochloride monohydrate (NS-21), a novel drug for urinary frequency and incontinence].
abstract: An antigenicity study of (+/-)-4-diethylamino-1,1-dimethylbut-2-yn-1-yl 2-cyclohexyl-2-hydroxy-2-phenylacetate monohydrochloride monohydrate (NS-21), a new drug for the treatment of urinary frequency and incontinence, was conducted in Hartley guinea pigs and BALB/cAnN mice. The following results were obtained. No active systemic anaphylaxis reactions were found in guinea pigs immunized by subcutaneous injection of NS-21 alone or in combination with Freund's complete adjuvant (FCA). No 24-hr heterologous passive cutaneous anaphylaxis reactions were elicited in rats by sera from mice immunized by intraperitoneal injection of NS-21 alone or in combination with 3% aluminum hydroxide gel. No passive hemagglutination reactions were elicited by sera from mice immunized by subcutaneous injection of NS-21 in combination with FCA. These results show that NS-21 has no antigenicity under the present experimental conditions.
