This study aimed to survey the quality of the marketed oral preparations containing active ingredients with a narrow therapeutic index, including Levonorgestrel, Levothyroxine, Phenobarbital, Phenytoin, and Warfarin. A total of 32 samples (25 domestic and 7 imported) were collected from hospitals, clinics, pharmacies, pharmaceutical firms and pharmaceutical manufacturers by local health authorities over the period of January-July 2022. All samples collected were inspected for quality control testings, including identification, assay, dissolution, uniformity of dosage units, and organic impurities. The analytical methods applied in evaluation consist of the regulations of Taiwan Pharmacopeia 9th edition, the British Pharmacopoeia 2022, and in-house methods from the manufactures with authorized specifications. The results indicated that all of the 32 samples met the requirements. |
