Tetracycline pharmacokinetics were studied in a group of normal subjects and in patients with nutritional oedema. Though both groups of subjects received similar dose per kilogram body weight, plasma concentrations and area under the curve (AUC) were significantly higher in nutritional oedema patients. The total body clearance of the drug was reduced due to significant reductions in renal and non-renal clearance of drug. The volume of distribution (VB) was low, with significant increase in rate of transfer of drug from peripheral to central compartment (K21), indicating poor tissue sequestration of the drug in nutritional-oedema patients. In some respects, these alterations in kinetics of tetracycline in nutritional-oedema patients are different from our earlier observations made in undernourished subjects who had mild and moderate forms of malnutrition. These results suggest that changes in disposition of drugs are also influenced by the severity of malnutrition, and demand suitable alterations in dosage regimen.
