ABSTRACT
OBJECTIVE: To establish an HPLC-UV-ESI-MSn method for the study of impurity profile of amoxicillin and clavulanate potassium tablets. METHODS: Agilent 1100 LC/MSD Trap liquid chromatography-mass spectrometry was used, and the column was Shim pack CLC-ODS RP18(4.6 mm×250 mm, 5 μm). The mobile phase A was 20 mmol·L-1 ammonium acetate (pH adjusted to 6.0), and the mobile phase B was 20 mmol·L-1 ammonium acetate-acetonitrile (20∶80) (pH adjusted to 6.0). Gradient elution was performed at a flow rate of 1.0 mL·min-1. ESI source was used. Positive and negative ion scan was conducted with a scanning range of m/z 100-1 500. The nebulizing pressure was 275.8 kPa, dry gas flow was 9 L·min-1, and post-column diversion ratio was 1∶5. Some related substances were identified by comparing the retention time in the chromatography, [M+H]+ spectrum and MS2 spectrum with those of the reference substances, while the others which do not have reference substances were deduced or speculated by analyzing the MS2 or MSn fragmentation with the help of a rule summarized from the MS2 fragmentation of amoxicillin, clavulanic acid and system suitability impurity reference substances. RESULTS: A total of 15 related substances were separated and characterized including nine known impurities like amoxicilloic acid, amoxicillin dimer, etc. and six unknown impurities. CONCLUSION: The method can be applied in the identification and qualitative analysis of the related substances in amoxicillin and clavulanate potassium tablets and is helpful for the quality control and optimization of the synthetic process.
ABSTRACT
Objective:To optimize the clinical dosage regimen of amoxicillin and clavulanate potassium extended release ( ER) tablets based on the PK/PD parameters. Methods:Totally 30 healthy subjects ( half male and half female) were randomly divided into three groups, and orally administered the ER tablets respectively under fasting condition, before the meal and after the meal, and the optimal administration time was determined by comparing the pharmacokinetic characteristics. The subjects in the three groups were ad-ministered the ER tablets respectively at low, medium and high dosage, and the optimal dosage and dosing interval were determined based on the PK/PD parameters. Results:Under fasting condition, the AUC of amoxicillin [(32.2 ±15.0) μg·h·ml-1] was sig-nificantly lower than that before the meal [(41.7 ±1.92) μg·h·ml-1] and that after the meal [(42.6 ±17.7) μg·h·ml-1]. In contrast, the AUC of clavulanate acid after the meal [(1.89 ±0.54) μg·h·ml-1] was significantly lower than that under fasting condition [(2.55 ±0.76) μg·h·ml-1] and that before the meal [(2.58 ±0.76) μg·h·ml-1] (P MIC) in 12 h was 5. 5, 7 and 10 h, and the percentage was 46%, 58% and 83%, respectively, and T> MIC in 12 h was 4. 5, 6 and 8 h, and the percentage was 38%, 50% and 67%, re-spectively when MIC was 4. 0μg·ml-1 . Conclusion:It is suggested that amoxicillin and clavulanate potassium ER tablets be taken at the start of a standard meal, 2 tablets per time, twice daily, which is sufficient to achieve T> MIC of 40% -50%.
ABSTRACT
The critical attribute was analyzed in clavulanate potassium tablet of amoxicillin according to the principle QbD. By investigation of the drug impurity profile, the cycle-closed dimer and penicilloic acid of amoxicillin were considered to be the critical impurities, and the sources and the degradation pathways of these two impurities were discussed. The research confirmed that crystal form was the critical attribute of drug substance. The drying process in the tablet granulation was regarded as the critical process parameter. The tablet formulation was also another factor in the impurity generation. This study provides a new idea for the evaluation of drug quality.
