In the state of fasting and fed single oral administration, the two kinds of vortioxetine hydrobromide tablets have good bioequivalence.
Bone-related infections represent a significant challenge in orthopedic practice, and the penetration efficacy of antimicrobials into bone tissue serves as a critical determinant of therapeutic outcomes. This review systematically summarizes the bone penetration characteristics of clinically used antimicrobial agents. Current evidence indicates that most β-lactam antibiotics demonstrate bone penetration rates ranging from 10% to 50%, while fluoroquinolones exhibit higher penetration at 30%-100%. Vancomycin and teicoplanin display penetration rates between 10% and 40%. Notably, clindamycin, linezolid and rifampicin achieve penetration rates exceeding 30%. Multiple factors influence drug penetration characteristics, including anatomical bone site variations, local blood perfusion status, patients’ pathophysiological conditions, as well as administration routes and dosage regimens.
The clinical isolation rate of carbapenem-resistant Acinetobacter baumannii (CRAB) has been increasing year by year, yet effective antimicrobial agents against this pathogen remain severely limited. Sulbactam-durlobactam, a novel β-lactam combination agent, has demonstrated promising in vitro antibacterial activity against CRAB. In May 2023, the U.S. Food and Drug Administration approved its use for patients aged 18 and older to treat hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia caused by susceptible isolates of the Acinetobacter baumannii-calcoaceticus complex, providing a new therapeutic option. This article reviews the mechanism of action, pharmacokinetics, pharmacodynamics, and clinical studies of sulbactam-durlobactam based on literature, aiming to offer insights for clinical practice.
Vancomycin is the first-line drug for treating infections caused by methicillin-resistant gram positive bacteria in patients with malignant hematological diseases. However, due to significant differences in the physiological and pathological characteristics of these patients compared to the general population, the pharmacokinetic behavior of vancomycin in the body may undergo significant changes. These changes may lead to unpredictable therapeutic effects, increased safety risks, and the evolution of bacterial resistance. Personalized dosing strategies may offer potential solutions to address these issues. Nevertheless, at present, there is a lack of unified, guideline-based, or consensus-driven reference standards for personalized dosing in these patients, particularly adult patients, and relevant research data remain insufficient. This review systematically summarizes the current status of pharmacokinetic studies on vancomycin in adult patients with malignant hematological diseases and focuses on the analysis of population pharmacokinetic models and their application progress. Additionally, this paper provides a detailed discussion of the current technical approaches available for vancomycin personalized dosing, including techniques based on therapeutic drug monitoring, clinical decision support systems, novel technical methods, and the latest dynamic dosing techniques developed by our research team based on individualized dosing models. Through an organized review of existing research, this paper identifies the challenges faced in achieving broader implementation of personalized dosing. It is hoped that this study will provide valuable insights for achieving personalized vancomycin dosing in patients with malignant hematological diseases, thereby advancing clinical practice and technological development in this field.

AS-IV can effectively improve intestinal and liver injury in rats with UC induced by TNBS. The mechanism may be related to repairing intestinal mucosal barrier, inhibiting inflammatory response and improving liver antioxidant function.
A 76 years old female patient was hospitalized twice for pulmonary infection and bronchiectasis with infection. During her first admission to the respiratory department for pulmonary infection, she received intravenous cefoperazone sodium/sulbactam sodium combined with bronchodilators for 11 days and was discharged following clinical improvement, with no documented adverse drug reactions (ADRs). During her second presentation to the emergency department for bronchiectasis exacerbation, the patient developed cyanosis and profuse sweating 13 minutes after intravenous cefoperazone/sulbactam administration. Despite successful resuscitation and subsequent transfer to the intensive care unit (ICU), emergency physicians failed to recognize this event as a suspected drug hypersensitivity reaction or document it in the medical records. After 11 days of meropenem therapy and symptomatic management in the ICU, she was transferred back to the respiratory department. Respiratory physicians initiated antibiotic de-escalation by readministering cefoperazone/sulbactam, which precipitated respiratory distress, profuse sweating and systemic discomfort within 19 minutes, followed by loss of consciousness and cardiopulmonary arrest. The patient died after 48 hours of unsuccessful resuscitation. This case serves as a reminder that the sensitization period for drugs can persist from several days to several months. The absence of ADRs with previous use does not entirely preclude the risk of subsequent administration. The recognition of hypersensitivity is critical, necessitating enhanced vigilance among healthcare professionals regarding ADRs. The documentation of ADRs and handover procedures during transfers between departments should not be overlooked to ensure medication safety.
To explore the clinical efficacy of fusidic acid ointment in patients with acne vulgaris who underwent non-ablative fractional 1 565 nm laser treatment.
Patients with common acne who received non-peeling fractional 1 565 nm laser treatment were divided into treatment group and control group. Treatment group was treated with fusidic acid ointment, 3 times a day, while control group was not treated with additional treatment.The lesion severity, skin sebum secretion, skin stratum corneum water content, clinical efficacy, matrix metalloproteinase 1 (MMP-1), matrix metalloproteinase tissue inhibitor-1 (TIMP-1), MMP-1/TIMP-1 ratio, skin elasticity indicators (R2, R5, R7), facial acne comprehensive grading system (global acne grading system, GAGS) score and acne-specific quality of life questionnaire (Acne-QOL) score were compared between the two groups.
