Paun D. and Franze J. from the Friedrichscheim Hospital in Berlin studied the therapeutic effectiveness of Tabex in 266 smokers, by comparing it to the effect obtained in 239 patients treated with placebo. The therapeutic results were followed on the 4th, 8th, 13th and 26th week of Tabex treatment. The patients with a serious intention to give up smoking have priority. On the 8th week, 55% of the patients treated with Tabex gave up smoking, this percentage decreasing to 26% at the end of the 26th week. However, the recidivists in the main group reduced twice the number of cigarettes smoked. The authors emphasize the statistically significant very good effect in the group treated with Tabex, compared to the group treated with placebo, and conclude that the drug may be successfully used when the patient has a serious intention to give up smoking, especially when the concomitant psychotherapeutic means cannot obtain such an effect.
