title: [Assessment of the use of oxybutynin hydrochloride (Pollakisu tablets) in the elderly].
abstract: Oxybutynin hydrochloride (Pollakisu tablets) was administered at a daily dose of 6 or 9 mg to 75 elderly patients with urinary tract disorders, including neurogenic bladder and unstable bladder, with chief complaints of pollakisuria, urgency on urination and urinary incontinence. A post-marketing follow-up survey (phase IV study) was then performed to evaluate the efficacy safety and usefulness of Pollakisu tablets in these patients. The administration of Pollakisu tablets produced good results in the comprehensive assessment of overall improvement, being rated as "improved" or better in 57.5% of the patients and "slightly improved" or better in 89.0%. The assessment of general safety revealed that the drug caused almost no problems, with "no problem in safety" accounting for 97.3% of the responses. The assessment of the usefulness indicated that Pollakisu tablets are highly useful, being rated as "useful" or better in 58.9% and as "slightly useful" or better in 82.2%. Evaluation of the results according to daily dose indicated that a dose of 6 mg per day was appropriate for elderly patients from the viewpoint of drug efficacy and safety. With respect to adverse reactions, thirst was found in 5 and dysuria in 3 of the 73 patients. The overall incidence of adverse reactions was 11.0%. The above results indicate the efficacy, safety and usefulness of Pollakisu tablets in treating elderly patients with pollakisuria, urgency on urination and urinary incontinence.
