Comparative Bioequivalence Study of 2 Clevidipine Formulations in Healthy Chinese participants: A Single-Dose, 2-Period Crossover Trial.

Clevidipine emulsion is an intravenous antihypertensive agent indicated for acute blood pressure control when oral therapies are contraindicated or ineffective. To address this gap in availability, a randomized, 2-period, 2-sequence crossover trial was conducted to evaluate the bioequivalence and safety of a generic clevidipine emulsion versus the reference product in 32 healthy Chinese adults. Participants received a 30-minute intravenous infusion of 3 mg of clevidipine (test or reference formulation) in each study period, with serial blood samples collected from the contralateral arm relative to the infusion site for pharmacokinetic analysis.

Effects of Food on the Pharmacokinetics and Safety of a Novel c-Met Inhibitor SPH3348: A Single-Center, Randomized, Open-Label, Single-Dose, 2-Period, 2-Sequence Crossover Study.

This randomized, open-label, 2-period crossover study evaluated food effects on SPH3348 pharmacokinetics (PK) and safety in 16 healthy participants receiving a single 480-mg dose under fasting and high-fat fed conditions. PK profiling involved serial blood sampling at 15 predefined time points per period, while safety assessments included continuous monitoring of adverse events throughout the study. PK analysis revealed pronounced food-dependent alterations.

Pharmacokinetic Study of Cefditoren Pivoxil in Breast Milk and Blood of Lactating Women.

To provide a theoretical basis for the rational use of cefditoren pivoxil in lactating women by conducting a pharmacokinetic study of cefditoren in the blood and milk of these women. Twelve participants meeting the inclusion criteria took cefditoren pivoxil tablets 200 mg after a meal, and the breast milk was collected over certain time periods with their volumes recorded. Blood samples were also collected at certain time points for pharmacokinetic analysis.

Design and synthesis of new alfa-naphthoflavanones as potent and selective CYP1B1 inhibitors.

Natural Flavanones are abundant in human diet and a few of them exhibited chemopreventive effects against xenobiotic procarcinogens through the inhibition of tumour specific CYP1B1 enzyme. Herein, a series of new alfa-naphthoflavanones were synthesised and evaluated for their enzymatic inhibitory potency and selectivity of CYP1B1 over its isoenzyme CYP1A1. The most active compound displayed highest inhibitory potency against CYP1B1 with the IC value of 0.

Guidelines for the clinical application of the pill for the prevention and treatment of breast hyperplasia diseases.

Context: The Xihuang pill (XHP) is a traditional Chinese medicine formulation that has been historically used in the prevention and treatment of proliferative breast diseases. However, there is a lack of guidelines that offer recommendations for its clinical use.

Objective: The task force from the Chinese Guangdong Pharmaceutical Association aims to develop evidence-based guidelines for XHP to prevent and treat proliferative breast diseases.

The complete chloroplast genome of provided insights into the phylogeny and species identification of .

is an important species within the family Aristolochiaceae, most of which contain nephrotoxic aristolochic acid. The inadvertent use of Aristolochiaceae plants as raw ingredients in the manufacturing of patent medicine poses a significant risk warranting considerable attention. In this study, we assembled and analyzed the complete chloroplast genome of , which is a 159 867 bp long circular molecule.

[Guideline for clinical comprehensive evaluation of Chinese patent medicine (2022 version)].

Currently,the research or publications related to the clinical comprehensive evaluation of Chinese patent medicine are increasing,which attracts the broad attention of all circles. According to the completed clinical evaluation report on Chinese patent medicine,there are still practical problems and technical difficulties such as unclear responsibility of the evaluation organization,unclear evaluation subject,miscellaneous evaluation objects,and incomplete and nonstandard evaluation process. In terms of evaluation standards and specifications,there are different types of specifications or guidelines with different emphases issued by different academic groups or relevant institutions.

A phase I, single-sequence, open-label study to evaluate the drug-drug interaction between hetrombopag and cyclosporine in healthy Chinese subjects.

Aims: This study aims to evaluate the drug-drug interaction (DDI) between hetrombopag and cyclosporine in healthy Chinese subjects.

Methods: Twenty-six eligible subjects enrolled in this single-centre, single-sequence, open-label, DDI study with 3 treatment periods, receiving 5 mg hetrombopag once on Day 1, 100 mg cyclosporine twice daily from Day 11 to Day 15 and 5 mg hetrombopag + 100 mg cyclosporine on Day 16. Serial blood samples were collected for pharmacokinetic evaluation.

A Single-dose, Two-Period Crossover Bioequivalence Study Comparing Two Liraglutide Formulations in Healthy Chinese Subjects.

Liraglutide, a glucagon-like peptide 1 receptor agonist, is indicated as an adjunct to diet and exercise to improve glycemic control in patients with type 2 diabetes. The original liraglutide products are costly, which limits patient access to this therapeutic treatment. Herein, a biosimilar was developed that is highly similar to the reference drug in molecular structure and bioactivity, and is expected to have similar pharmacokinetic (PK) and safety profiles in clinical studies.

Effectiveness and safety of Danmu extract syrup for acute upper respiratory tract infection in children: A real-world, prospective cohort study.

Aim: To evaluate the effectiveness and safety of Danmu Extract Syrup for the treatment of acute upper respiratory tract infection (AURI) in children.

Methods: In this prospective cohort study, we enrolled children with AURI in the pediatric outpatient department and emergency department of West China Second Hospital. According to the treatment, they were divided into two groups: Danmu Extract Syrup Group (Danmu Group) and Xiaoer Chiqiao Granule Group (Chiqiao Group).

Clinical pharmacist participation in selecting and dosing targeted drugs for a patient with ALK-positive non-small cell lung cancer: a case report.

Ceritinib and alectinib are recommended as the second-line therapies in the 2019 Chinese Society of Clinical Oncology (CSCO) guidelines for patients with anaplastic lymphoma kinase (ALK) positive non-small-cell lung cancer (NSCLC) in whom the first-line therapy has failed, but no optimal second-line treatment has been identified. Before 2018, the approved dose of ceritinib in the United States and many other countries was 750 mg/d fasted. In China, the approved dose was 450 mg/d fed although the dose of 750 mg/d fasted is still used in clinical practices.

Characterization of the Complete Chloroplast Genome of Buddleja lindleyana.

Background: Buddleja lindleyana Fort., which belongs to the Loganiaceae with a distribution throughout the tropics, is widely used as an ornamental plant in China. There are several morphologically similar species in the genus Buddleja, but the lack of comprehensive molecular and phylogenetic studies makes it difficult to distinguish related species, which hinders further studies of this genus.
