Background: Off-label drug use exists widely in medical practice and is also an area which easily triggers controversy between patients and medical institutions. Previous studies have identified the reasons why off-label drug use long exists. However, there is no multidimensional analysis on real judicial precedents about off-label drug use. This study aimed to investigate the dispute points on off-label drug use based on real cases in China, and proposed suggestions based on newly-leased Physicians Law. Methods: Our study is a retrospective study with all the 35 judicial precedents on off-label drug use extracted from China Judgments Online from 2014 to 2019. This study mainly used the methods of statistical analysis, inferential analysis, exemplification, literature summarization and comparative analysis. Results: According to the analysis of the 35 precedents of jurisdictions from 11 different aspects, it can be seen that the second-instance and retrial rates of this kind of cases are high, and the disputes between patients and medical institutions are fierce. In judicial practice of off-label drug use, medical institutions are determined whether to bear civil liability according to the constituent elements of medical tort liability: the rate of medical institutions' bearing liability for off-label drug use is not high, and medical institutions are not directly identified as infringing acts and they don't bear tort liability. The clear provisions about off-label drug use in Law of the People's Republic of China on Physicians which was implemented in March 2022 confirm this at the legislative level. Conclusions: By analyzing the current judicial practice of China's off-label drug use cases, and summarizing the dispute points between medical institution and patients, the constituent elements of tort liability, and the rules of evidence etc., suggestions are proposed to further regulate off-label drug use and promote safe and rational drug use.

Background: The high cost and prolonged timeline of new drug discovery and development are major roadblocks to creating therapies for infectious diseases. Candida albicans is an opportunistic fungal pathogen that is the most common cause of fatal fungal infections in humans and costs $2-4 billion dollars to treat in the US alone. Methods: To accelerate drug discovery, we screened a library of 1581 existing FDA approved drugs, as well as drugs approved abroad, for inhibitors of C. albicans. The screen was done on YPD yeast growth media as well as on the serum plate assay developed in this study. Results: We discovered that fifteen drugs, all which were originally approved for treating various infectious and noninfectious diseases, were able to kill Candida albicans. Additionally, one of those drugs, Octodrine, displays wide-spectrum anti-microbial activity. Compared to other selected anti-Candida drugs, Octodrine was shown to be one of the most effective drugs in killing serum-grown Candida albicans without significantly affecting the survival of host macrophages and skin cells. Conclusions: This approach is useful for the discovery of economically viable new therapies against infectious diseases. [ABSTRACT FROM AUTHOR]

Background Many common drugs have not been licensed for use in children. Methods This study evaluated the incidence of unlicensed and off-label prescriptions at the Department of Pediatrics during a period of six months. A total of 8,559 prescriptions for 4,282 children were processed. Results Off-label and unlicensed prescriptions were found in 9.01% and 1.26% of all prescriptions, respectively. Unlicensed prescriptions were significantly more common in boys (1.5%) than in girls (1.0%) (p = 0.037). There was no significant difference between off-label prescriptions in boys (9.0%) and in girls (9.1%) (p = 0.89). The prescription of unlicensed drugs was significantly more frequent in school age children (p < 0.0001). The most commonly prescribed unlicensed drugs were angiotensin-converting enzyme inhibitors; among off-label drugs, antihistamines and bronchodilators. Conclusions This study shows that the incidence of unlicensed and off-label drug prescriptions in our patients is not as high as in other studies. [ABSTRACT FROM AUTHOR]
