INTRODUCTION: In Germany, incidence rates of basal cell (BCC) and squamous cell carcinoma (SCC) rose significantly from 1998 to 2010. Ultraviolet (UV) light exposure, immunosuppressants and drugs with photosensitising potential are known to increase the risk to develop BCC and SCC. The aim of our study was to analyse the adverse drug reaction (ADR) reports from Germany referring to BCC and SCC and to compare them to BCC and SCC occurring in the general population. METHODS: We analysed all validated spontaneous ADR reports referring to BCC (n = 191) and SCC (n = 75) from Germany contained in the European ADR database EudraVigilance prior to 6 March 2019...

BACKGROUND: Cloperastine is a pivotal antibechic widely prescribed to treat cough caused by respiratory diseases. The present trial evaluated the pharmacokinetics (PK), bioequivalence (BE) and safety effects of the generic test (T) tablet of cloperastine after single-dose administration of cloperastine, compared with the original reference (R) tablet of cloperastine. OBJECTIVE: The purpose of this trial was to compare the PK, BE and safety of a test 10 mg versus the reference 10 mg formulation of cloperastine under fasting and postprandial conditions in healthy Chinese volunteers...

OBJECTIVE: We aimed to assess the bioequivalence, safety, and tolerability of Chinese- and French-manufactured Glucophage® immediate-release (GIR) tablets under fasted and fed conditions in healthy volunteers. A bioequivalence study was proposed to support the manufacturing transfer. METHODS: This was an open-label, randomized, two-period, two-sequence, crossover study. Subjects were randomly assigned to receive the test product (one 500 mg GIR tablet manufactured in China) or reference product (one 500 mg GIR tablet manufactured in France)...

BACKGROUND AND OBJECTIVE: Pharmacokinetic or pharmacokinetic-pharmacodynamic models have been instrumental in facilitating the clinical use of propofol in target-controlled infusion systems in anaesthetic practice. There has been debate over which model should be recommended for practice. The covariates model is an updated pharmacokinetic model for propofol. The aim of this study was to prospectively validate this model in an adult population. METHODS: Twenty-nine patients were included, with a range of ages to assess model performance in younger and older individuals...

BACKGROUND AND OBJECTIVES: Aspirin is a common drug for the treatment of pre-eclampsia. We aimed to explore whether quercetin as a supplement to aspirin could enhance the therapeutic outcome in pre-eclampsia rat models. We further aimed to evaluate the nucleotide-binding oligomerization domain-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome as a potential pre-eclampsia-related molecular mechanism, which can be affected by quercetin treatment. METHODS: Rat pre-eclampsia models were established using an intravenous lipopolysaccharide injection after gestation...

BACKGROUND: Chromogenic anti-factor Xa activity (AXA) assay is used to measure the pharmacodynamics of factor Xa inhibitors, including edoxaban. Although AXA concentrations in patients with non-valvular atrial fibrillation using edoxaban have been reported, the impact of renal function on AXA concentrations with edoxaban use in patients with non-valvular atrial fibrillation has not been fully assessed. METHODS: Trough and peak AXA concentrations were measured in 93 patients with non-valvular atrial fibrillation taking edoxaban (73...

AIM: The purpose of this study was to evaluate the extended physicochemical and biological stability of Sandoz Rixathon®/Riximyo® (SDZ-RTX) after exposure to out-of-fridge (OOF) conditions.
