An educational program targeted to physicians, nurses, and aides can reduce the use of psychoactive drugs in nursing homes without adversely affecting the overall behavior and level of functioning of the residents.
Patterns of cimetidine use were identified in a survey of 3032 patients in 31 nursing homes. Of these, 60 (2%) were receiving cimetidine. For these patients, ages ranged from 63 to 102 years (mean, 81 years). The patients received a range of 1 to 11 regularly scheduled medications (mean, 5.6 medications). Duration of cimetidine treatment averaged 19.6 months for 48 patients (81%) receiving the drug for longer than an eight-week course of therapy. Prescribing indications appeared unjustified in 54 of 60 patients (90%). Doses were rarely appropriately reduced for patient age, despite established reasons to do so and the well-known potential for adverse effects of cimetidine in the elderly. The risks associated with prolonged drug-induced suppression of gastric acid are not known. This study suggests that use of cimetidine without justifiable indication and for extended periods of time is common in nursing home patients. Studies are needed concerning the safety of long-term cimetidine use in elderly patients.
Withdrawal from hypnotics can produce a variety of problems, especially sleep difficulties, some of which may arise from the multiple actions of most hypnotics, thus producing a range of rebound effects. This study examined whether switching patients to a hypnotic with a narrower range of action and of a different class would reduce these problems. One hundred and thirty-four patients participated; they were randomly allocated to one of three methods of switching from "previous hypnotic" to zopiclone (a cyclopyrrolone). The methods were gap (an interval between taking the two drugs); abuttal (taking zopiclone immediately on stopping previous drug); and overlap (gradually reducing previous drug after starting zopiclone). The main findings were that zopiclone was associated with better sleep and increased alertness; the abuttal method was the best method of switching; and no serious side effects from zopiclone were reported. It was concluded that zopiclone has a useful role in benzodiazepine withdrawal, and that immediate substitution is the best method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
