Drogas anorexígenas en el tratamiento de la obesidad / Anorexigenic drugs in the treatment of obesity

Obesity is highly prevalent and has several adverse effects on health. Its treatment is thus warranted and must aim to modify dietary and physical activity habits. The opinion of this association is that anorexigenic drugs with cathecolaminergic action (diethylpropion, phentermine, mazindol and phenylpropanolamine) or serotoninergic action (fenfluoramine and fluoxetine) may be used in moderate or severe obesity (BMI >30 kg/m2) after a complete clinical assessment and in the context of an integral medical treatment. This association recommends a close surveillance of the use of these drugs, specially when formulated as non-propietary prescriptions

Effect of d-fenfluramine on cortical spreading depression in rats

We investigated the effect of a single ip injection of ed-fenfluramine (d-fen; 5-10 mg/kg), a serotinin reuptake blocker, on cortical spreading depression (SD) in 17 male Wistar rats (300-360 g body weight). SD was elicited at the right frontal cortex by 1-min application of 2 percent KCl at 20-min intervals. SD propagation was monitored (electrocorticogram and DC-recording) at 2 points on the right parietal surface for 3 h. After a "baseline" recording period (1 h), d-fen was injected and the recording session was continued for 2 h. When compared to the predrug SD velocities (t = 0 min) the values measured after d-fen decreased significantly at t = 20 min (3.44 + or - 0.63 vs 2.66 + or - 0.51 mm/min; N = 17, P<0.001), at t = 40 min (3.32 + or - 0.58 vs 2.53 + or - 0.52 mm/min; N = 14, P<0.001), att=60 min (3.68 + or - 0.63 vs 2.92 + or - 0.72 mm/min; N = 11, P<0.001) and at t = 80 min (3.57 + or - 0.61 vs 3.03 + or - 0.83 mm/min; N = 12, P<0.05) but not at t = 100 min (3.47 + or - 0.72 vs 3.31 + or - 0.88 mm/min; N = 12) nor at t = 120 min (3.44 + or - 0.67 vs 3.37 + or - 0.76 mm/min; N = 11). Furthermore, in 19 of 48 KCl stimulations (40 percent) performed ...
