Prescription and intake patterns in long-term and ultra-long-term benzodiazepine treatment in primary care practice.
Pharmacoepidemiological data show that long-term treatment accounts for a considerable part of benzodiazepine prescriptions in primary care practice. Prescription and intake patterns were, therefore, investigated in a study of 196 patients who had been treated with benzodiazepines for longer than six months by internists or general physicians in private practice. Patients were 64 years of age on average, half of them being 65 years or older. Females were in the majority (73.5%). The average duration of tranquilizer or hypnotic intake was 11.0 years, or 5.3 years for the current benzodiazepine medication. The mean daily dose was 9 mg diazepam equivalent. All benzodiazepine hypnotics and 61% of benzodiazepine tranquilizers had been prescribed solely for night-time use. Only 6% of the patients were taking benzodiazepines as single medication: on average they were taking 3.1 additional types of medication for other conditions, these being predominantly cardiac and antirheumatic/analgesic in nature. One in five patients was taking additional psychotropic medication. The compliance coefficient was on average 0.8, showing that patients did not tend to abuse benzodiazepines, with noncompliance generally being similar to noncompliance with other forms of medication.
