Metabolomics in drug research and development: The recent advances in technologies and applications

Emerging evidence has demonstrated the vital role of metabolism in various diseases or disorders. Metabolomics provides a comprehensive understanding of metabolism in biological systems. With advanced analytical techniques, metabolomics exhibits unprecedented significant value in basic drug research, including understanding disease mechanisms, identifying drug targets, and elucidating the mode of action of drugs. More importantly, metabolomics greatly accelerates the drug development process by predicting pharmacokinetics, pharmacodynamics, and drug response. In addition, metabolomics facilitates the exploration of drug repurposing and drug-drug interactions, as well as the development of personalized treatment strategies. Here, we briefly review the recent advances in technologies in metabolomics and update our knowledge of the applications of metabolomics in drug research and development.

Antimicrobial Effectiveness of Domestic Lomefloxacin Hydrochloride Eye Drops / 中国药师

Objective:To evaluate the antimicrobial effectiveness of lomefloxacin hydrochloride eye drops from 13 domestic manu-facturers. Methods:The antimicrobial effectiveness of lomefloxacin hydrochloride eye drops was tested based on the antimicrobial ef-fectiveness testing in Chinese Pharmacopoeia(2015 edition,volume 4). Results:The samples from 5 manufacturers could reach level A,those from 3 manufacturers were at level B, and those from 5 manufacturers did not comply with the specification. Conclusion:Some problems exist in the usage of antimicrobial agents in lomefloxacin hydrochloride eye drops from some Chinese manufacturers,and these manufacturers should optimize the type and concentration of antimicrobial agents according to the requirements of Chinese Phar-macopoeia combined with the corresponding prescriptions under the principle of minimum concentration while best effect.
