[Action of some drugs on pressure profile of female urethra (author's transl)].
The action of certain drugs upon the urethra of clinically intact women was studied by measurement of the urethral profile. beta-adrenoreceptor stimulating and blocking agents, such as fenoterol, propanolol, as well as cholinergics, including carbachol and pyridostigmine, failed to exercise any effect on the urethral pressure profile. On the other hand, anticholinergics, such as atropine and N-butylscopolammonium-bromide, diazepam, and chlorpromazine, produced significant decrease in both maximum urethral pressure and maximum urethral closure pressure. N-butylscopolammonium-bromide and chlorpromazine also shortened the functional length of urethra. Drop of all parameters relating to the urethral pressure profile was observed to take place in response to application of succinylcholine. Phentolamine, an alpha-adrenoreceptor blocking agent, then was administered and caused further reduction of those parameters. The pressure values were elevated by ketamine. The above findings are discussed and compared to present concepts published in literature on medicamentous control of urethral function.
