Emepronium bromide (Cetiprina) is a quarternary ammonium compound with anticholinergic effects. It is mainly used in the treatment of urinary frequency, urge and urge incontinence and is usually administered orally and occasionally intramuscularly. Emepronium bromide was introduced into Britain, after having been used in Sweden for a number of years. The drug was advocated especially for elderly patients suffering from nocturia and urgency with incontinence, when these were due to causes other than obstruction. It was also advocated for enuresis and hypertonic bladder states following surgery or radiotherapy.
