Obesity is common enough to constitute a serious medical and public health problem. Drug prescription for obese patients is difficult since dosages based on pharmacokinetic data obtained in normal-weight individuals could induce errors. In obese patients, physiopathological modifications are likely to affect drug tissue distribution and elimination. ⋯ For drugs markedly distributed into fat tissue the loading dose is based on total bodyweight. Adjustment of the maintenance dose depends on possible changes in CL. In some cases (atracurium, prednisolone) dosage adjustment does not follow these recommendations, owing to pharmacodynamic data.
