A crossover-randomized bioequivalence study of two oral formulations of esomeprazole (40 mg) capsules were carried out in 16 healthy male Bangladeshi volunteers. The test and reference formulations were PRONEX™ (Drug International Ltd, Bangladesh) and NEXIUM™ (AstraZeneca AB, Sweden), respectively. Each tablet was administered with 150 mL of water to subjects after overnight fasting on 2 treatment days separated by 1 week washout period. After dosing, serial blood samples were collected for a period of 24 hours. The plasma concentrations of esomeprazole were estimated using a validated HPLC method. The pharmacokinetic parameters Cmax, Tmax, AUC0g24h, t1/2, and Kel were determined. The mean (± SD) AUC0g24h for esomeprazole of test drug PRONEXTM for 16 volunteers was 1509 (± 546) ng.hr/mL whereas it was 1622 (± 589) ng.hr/mL for esomeprazole of NEXIUMTM. The relative bioavailability (PRONEXTM/NEXIUMTM ratio) was 93%. The Cmax, tmax, half-life of elimination (t1/2) and the rate of elimination (Kel) of esomeprazole of test drug were 1653 (± 706) ng/mL, 2.13 (± 0.81) hours, 2.00 (± 0.61) hour and 0.3465 respectively. The Cmax, tmax, half-life of elimination (t1/2) and the rate of elimination (Kel) of esomeprazole of reference drug were 1820 (± 877) ng/mL, 2.80 (± 0.67) hours, 2.14 (± 0.55) hour and 0.3238 respectively. The 90% CI for the test and reference drugs were found within the acceptance range of 80-125%. In conclusion, PRONEX™ is bioequivalent to NEXIUM ™ in terms of absorption.KYAMC Journal Vol. 4, No.-1, July 2013, Page 326-330

Introduction/Study Objectives: A bioequivalence study was performed to compare the pharmacological profile of innovator etoricoxib (ETO) with a newly developed generic ETO, both in a 120 mg tablet formulation. A dissolution study was conducted to optimize the formulation process before evaluating physical changes in the active pharmaceutical ingredient and the formulated product. Methods: This was a randomized, open-label, balanced, two-treatment, two-period, two-sequence, single-dose, two-way crossover, truncated bioequivalence study involving a washout period of ten days. A total of 26 healthy male volunteers were recruited. The pharmacokinetic profile of the test formulation was compared with the reference formulation. Results/Discussion: The pharmacokinetic parameters of ETO were calculated based on the plasma drug concentration-time profile using non-compartmental analysis to determine its safety profile and tolerability. The Test/Reference (T/R) ratio of ETO was 104.36% (90% confidence interval (CI): 98.30%–110.80%) for area under curve (AUC)0-72 while the T/R ratio of maximum concentration (Cmax) was 101.39% (92.15%–111.56%). The 90% CI of the Cmax and AUC0-72 of ETO were within acceptable bioequivalence limits of 80%–125%. All values were within the predetermined limits of the Association of Southeast Asian Nation (ASEAN) bioequivalence guidelines. Conclusion: The test formulation was found to be bioequivalent with respect to the reference drug, according to ASEAN bioequivalence guidelines.

Abstract Background Previous pharmacokinetic studies demonstrated an increase in serum ertapenem concentrations with decreasing kidney function, including patients receiving renal replacement therapy. This study evaluated the pharmacokinetic parameters of ertapenem in patients receiving hemodialysis. Methods This prospective, single-center, open-label study examined the pharmacokinetics of a single intravenous (IV) dose of ertapenem 1 g in seven hospitalized noninfected patients undergoing hemodialysis. Blood samples were collected prior to ertapenem administration and at 0.5, 1, 2, 6, 12 and 48 hours (h) after administration. Ertapenem concentrations were determined by validated liquid chromatography mass spectrometry assay. Results Following an IV bolus of 1 g ertapenem, plasma concentrations declined relatively slowly with a mean ±standard deviation (SD) elimination half-life of 19.3 ±6.6 h. Plasma concentrations were similar in all subjects, with maximum mean plasma concentration observed of 343±48 µg/mL postdose. The mean ±SD values for systemic plasma clearance (CL) and volume of distribution at steady state (Vss) were 2±0.5 mL/min and 3295±1187 mL, respectively. The area under the curve for 0 h–∞ (AUCinf) was 7494 ±1424 h•µg/mL. No gender effect was observed and no serious adverse events were reported. Conclusions Ertapenem half-life was prolonged in hemodialysis patients. Considering the nonrenal clearance and the expected 70% removal with high-efficacy hemodialysis, the dose of 1 g ertapenem, three times weekly, after hemodialysis may produce pharmacodynamically sufficient exposure for potential antimicrobial efficacy. Further studies are warranted to assess the clinical efficacy and safety of this dose with prolonged duration of therapy.

Objectives The aim of this study was to determine the plasma pharmacokinetic profile, tissue concentrations and urine elimination of cefazolin in cats under surgical conditions after a single intravenous dose of 20 mg/kg. Methods Intravenous cefazolin (20 mg/kg) was administered to nine young mixed-breed cats 30 mins before they underwent surgical procedures (ovariectomy or orchiectomy). After antibiotic administration, samples from blood, some tissues and urine were taken. Cefazolin concentrations were determined in all biological matrices and pharmacokinetic parameters were estimated. Results Initial plasma concentrations were high (Cp(0), 134.80 ± 40.54 µg/ml), with fast and moderately wide distribution (distribution half-life [t½(d)] 0.16 ± 0.15 h; volume of distribution at steady state [V(d[ss])] 0.29 ± 0.10 l/kg) and rapid elimination (body clearance [ClB], 0.21 ± 0.06 l/h/kg; elimination half-life [t½], 1.18 ± 0.27 h; mean residence time 1.42 ± 0.36 h). Thirty to 60 mins after intravenous administration, cefazolin tissue concentrations ranged from 9.24 µg/ml (subcutaneous tissue) to 26.44 µg/ml (ovary). The tissue/plasma concentration ratio ranged from 0.18 (muscle) to 0.58 (ovary). Cefazolin urine concentrations were high with 84.2% of the administered dose being eliminated in the first 6 h postadministration. Conclusions and relevance Cefazolin plasma concentrations remained above a minimum inhibitory concentration of ⩽2 µg/ml up to 4 h in all the studied cats. This suggests that a single intravenous dose of 20 mg/kg cefazolin would be adequate for perioperative prophylactic use in cats.

Background6-mercaptopurine (6-MP), a key drug for treatment of acute lymphoblastic leukemia (ALL), has until recently had no adequate formulation for pediatric patients. Several approaches have been taken but the only oral paraben-free 6-MP liquid formulation named Loulla was developed and evaluated in the target population. Preclinical and clinical evaluation was performed according to a Pediatric Investigation Plan, in order to apply for a Pediatric Use Marketing Authorization.MethodsThe pre-clinical study assessed the maximum tolerated dosage-volume and evaluated local mucosal toxicity of 28 daily administrations in treated compared to controls gold hamsters. The multi-centre clinical study was single-dose, open-label, crossover trial, conducted in 15 ALL children during maintenance therapy. The bioavailability and palatability of a single 50 mg fixed dose of Loulla compared to 50 mg registered tablets were evaluated in a random order on two consecutive days. Seven blood samples over 9 hours were obtained each day at to determine 6-MP pharmacokinetic parameters, including Tmax, Cmax, AUC0–9 and AUC0–∞. A questionnaire adapted to children testing Loulla palatability and preference for either Loulla or the usual 6-MP tablet was completed. Occurrence of adverse events was determined at study visits by vital sign measurements, patient's spontaneous reporting, investigator's questioning and clinical examination.ResultsThe preclinical study in gold hamsters showed that dosage-volume of 75 mg/kg/day was well tolerated. The relative bioavailability of liquid Loulla formulation compared to the reference presentation is 76% for AUC0-9 and AUC0-∞ and 80% for Cmax. The taste of Loulla and the mouth feeling after ingestion compare favorably to the tablet. No adverse event occurred.ConclusionPharmacokinetic, palatability and safety data support the use of Loulla in children.
