Bracketed Stability Evaluation of Methimazole USP in PLO Gel Mediflo™30 Pre-Mixed.
Extemporaneously compounded Methimazole 1% and 10% in PLO Gel Mediflo™30 Pre-Mixed were studied to assess physical, chemical and microbial stability over time. The formulations were stored at room temperature in tightly closed, light resistant plastic containers. Chemical stability was evaluated using a validated, stability indicating HPLC analysis and physical stability was evaluated through observation of organoleptic appearance and pH measurement at predetermined time points. Lastly, antimicrobial effectiveness testing was conducted per USP <51> guidelines. The results indicate that compounded Methimazole remained within the stability criteria for the duration of the study and can be assigned an extended beyond-use-date of 120 days under the studied conditions.
期刊介绍：
The International Journal of Pharmaceutical Compounding (IJPC) is a bi-monthly, scientific and professional journal emphasizing quality pharmaceutical compounding. IJPC is the only publication that covers pharmaceutical compounding topics relevant and necessary to empower pharmacists to meet the needs of today"s patients. No other publication features hands-on, how-to compounding techniques or the information that contemporary pharmacists need to provide individualized care.
