Résumé

In a crossover study, lithium was given orally at a dose of 56 mg/kg, prepared as suspension (0.5%) in carboxymethyl cellulose (CMC) and blood samples (1 ml) collected after 0-24 hr after drug administration. After a washout period of two weeks, nimesulide (10 mg/kg) was administered alongwith lithium (56 mg/kg) and blood samples were drawn at the same time intervals (0-24 hr) after drug administration. Plasma was separated and assayed for lithium by M 654 Na+/K+/Li+ analyzer and various pharmacokinetic parameters were calculated. C(max), K(el), t(1/2el) and AUC(0-alpha) of lithium were significantly increased when nimesulide was administered along with lithium as compared to control group.

Résumé

The study was aimed at determining the effect of Coca-Cola on the pharmacokinetics of ibuprofen in rabbits. In a cross-over study, ibuprofen was given orally in a dose of 56 mg/kg, prepared as 0.5% suspension in carboxymethyl cellulose (CMC) and blood samples (1 ml) were drawn at different time intervals from 0-12 hr. After a washout period of 7 days, Coca-Cola in a dose of (5 ml/kg) was administered along with ibuprofen (56 mg/kg) and blood samples were drawn from 0-12 hr. To these rabbits, 5 ml/kg Coca-Cola was administered once daily for another 7 days. On 8th day, Coca-Cola (5 ml/kg) along with ibuprofen (56 mg/kg), prepared as a suspension was administered and blood samples (1 ml each) were drawn at similar time intervals. Plasma was separated and assayed for ibuprofen by HPLC technique and various pharmacokinetic parameters were calculated. The Cmax and AUC0-alpha of ibuprofen were significantly increased after single and multiple doses of Coca-Cola, thereby indicating increased extent of absorption of ibuprofen. The results warrant the reduction of ibuprofen daily dosage, frequency when administered with Coca-Cola.
