Body weight evolution during dexfenfluramine treatment after initial weight control.

While very low calorie diets (VLCD) can lead to rapid weight loss, even in patients who have often failed with conventional diets, maintaining this loss remains a clinical challenge. Since dietary re-education or more formal behaviour modification techniques are not easily applicable to large numbers of patients and are not always successful, drugs to maintain and improve upon initial VLCD success would be of clinical benefit. Pharmacological treatment of obesity has evolved in recent years with the development and licensing of potent serotonin agonists, such as dexfenfluramine (D-F). VLCD followed by D-F has been shown to be effective. A double-blind trial randomized 45 patients who had successfully completed eight weeks' VLCD treatment, to either placebo or D-F 15 mg b.d. for 26 weeks. Patients continued on a diet giving 60-75% of daily energy needs. Patients treated with D-F had lost 14.9 +/- 0.9 kg on the Cambridge diet and a further 5.8 +/- 1.8 kg during the drug treatment. In contrast, patients who received placebo regained 2.9 +/- 1.3 kg of the 13.5 +/- 1.0 kg they had lost during VLCD. The total weight loss after 34 weeks in total was thus 21.3 +/- 2.6 versus 11.3 +/- 1.9 kg. Patients were offered the option of continuing on D-F, or switching from placebo, in an open continuation of the trial. Ten patients, regaining weight on placebo, stabilized their weight without further regain over the next 24 weeks when switched to D-F.(ABSTRACT TRUNCATED AT 250 WORDS)
