RESUMEN

OBJECTIVES: To evaluate the clinical importance of the interaction between carbamazepine (CBZ) and dextropropoxyphene in elderly patients. METHODS: All patients (n = 7263) in Gothenburg, Sweden, who were part of a drug-dispensing programme, were included in the study. Eight per cent of the patients took CBZ and 18% took dextropropoxyphene, continuously. Patients who used a combination of these drugs were compared with patients who took only CBZ or dextropropoxyphene or neither of the two drugs. These four groups of patients were matched to each other with reference to gender, age and concomitant medication, which finally resulted in 21 patients in each group. A questionnaire with 30 symptoms of well-being, including symptoms typical of adverse effects of CBZ, were answered by the patients with the help of a registered nurse. Venous blood samples were drawn from the patients for the analysis of CBZ, its metabolite CBZ 10,11-epoxide (CBZ-E) and dextropropoxyphene. RESULTS: The doses of CBZ and dextropropoxyphene were lower among patients who used the combination of the two drugs than among those who only used one of the drugs. The mean level of CBZ in serum (S-CBZ) was, however, significantly higher and the level of CBZ-E in serum (S-CBZ-E) significantly lower among the patients who used the combination of CBZ and dextropropoxyphene, thus indicating an inhibition of the metabolism of CBZ. The prevalence of symptoms indicating side effects of CBZ was significantly higher in the group of patients who used both drugs. CONCLUSION: This study has shown that the combination of CBZ and dextropropoxyphene is hazardous in elderly patients and should be used with caution.
