RESUMO
The efficacy tolerance of Lysine Clonixinate (LC), a NSAID with prostaglandin synthesis inhibiting mechanism was studied in 24 patients with primary dysmenorrhea according to a double-blind randomized crossover Placebo (P) controlled design with patients serving as their own controls. Treatment consisted in administering 1 tablet of LC or P q6h as from onset of menstrual pain during 5 days and 6 menstrual cycles. Patients were controlled monthly as from the 5th day of the cycle rating changes in pain intensity according to a 4-point scale, presence of pain during pre-, post-and menstrual periods possible intracycle changes, amount of bleeding, tolerance and related total and general signs and symptons. Intensity of baseline menstrual pain amounted to 2.9. Menstrual, intramenstrual and postmenstrual pains were observed in 19 out of 24,24/24 and only 2 out of the patients, respectively. Concomitant symptons consisted in headache (12), mastalgia (14) and disconfort (12). Results were obtained by averaging the data from the 3 tratment periods with each drug. Menstrual pain was reduced from 2.9 + 0.7 to 1.9 + 0.7 with P administration and to 0.66 + 0.4 with the administration of LC, a highly significant difference between tratments (p<0.0001). Premenstrual pain was reduced nonsignificantly from 0.79 per cent to 0.58 per cent with P administration and significantly to 0.29 per cent with administration of LC (p<0.001). Intramenstrual pain affection all patients at baseline was reduced significantly by 8 per cent with P and also significantly by 50 per cent with LC p<0.001). No differences were encontered in encomitant symptoms during P treatment periods while the incidence was significantly reduced with LC (p<0.0001). No changes in cycle duration or amount of bleeding were observed between treatments. No adverse events were reported.
