[Clinical study of terodiline hydrochloride on nervous pollakisuria]

TD-758 (12 mg tablets) was given in two tablets daily to 19 patients with nervous pollakisuria. The changes in frequency of daily micturition and in subjective symptoms were studied referring to the diary kept by each patient, along with the occurrence of side effects. Before the medication, urodynamic studies were made on each patient and all the cases were thus confirmed being free from detrusor instability or uninhibited contraction. The wash-out period of other drugs and control observation period, each one week, were set before the medication period which lasted for four weeks. The frequency of micturition per day showed a significant decrease from the first week of the medication period (p less than 0.05), and at the fourth week there was noted a significant reduction by twice per day on the average (p less than 0.001). Subjective efficacy was noted as follows: excellent in 3 cases (15.8%), good in 9 cases (47.7%), unchanged in 7 cases (36.8%), and thus 12 cases (63.2%) showed an efficacy of the rating of good or higher. In four cases dry mouth and in two cases sense of abdominal distention were noted out of the total of 19 cases, but no side effects of severe degree to stop the medication were noted during the medication period. In conclusion TD-758 is a clinically useful remedy for treatment of nervous pollakisuria.
