To assess the influence of pretreatment with cimetidine on changes in hepatocellular integrity after halothane anaesthesia, 53 patients were allocated randomly to receive either cimetidine 1600 mg orally or placebo tablets before anaesthesia. Plasma concentrations of glutathione S-transferase (GST) were measured as an index of hepatic damage. Data from 45 patients were available for analysis. Plasma GST concentration increased significantly 3 h after induction of anaesthesia in both groups (P less than 0.01, both groups) and at 6 h in the cimetidine group (P less than 0.05). Pretreatment with cimetidine did not influence the magnitude of increase in GST concentration. There was no difference between the groups in the frequency of abnormal GST concentrations at any time. Cimetidine does not appear to prevent release of GST from the liver by halothane anaesthesia in man.

Introduction: Cadonilimab (AK104) is an innovative human programmed cell death-1 (PD-1)/cytotoxic T lymphocyte antigen-4 (CTLA-4) bispecific antibody. Compared with the combination therapy of PD-1 and CTLA-4 blockers, less cellular toxicity of cadonilimab was significantly manifested. As one of the characteristic adverse effects of cadonilimab, infusion-related reactions (IRRs) represent fever, chills, rash, decreased blood pressure, and other symptoms.

Transporter-mediated drug-drug interactions (DDIs) are of concern in antimicrobial drug development, as they can have serious safety consequences. We used positron emission tomography (PET) imaging-based pharmacokinetic (PK) analysis to assess the effect of different drugs, which may cause transporter-mediated DDIs, on the tissue distribution and excretion of [F]ciprofloxacin as a radiolabeled model antimicrobial drug. Mice underwent PET scans after intravenous injection of [F]ciprofloxacin, without and with pretreatment with either probenecid (150 mg/kg), cimetidine (50 mg/kg), or pyrimethamine (5 mg/kg).

Background: The mechanisms of emergence from general anesthesia remain to be elucidated. Recent studies indicate that the central histaminergic system plays a critical role in maintaining wakefulness. In addition, the neural pathways that regulate the wake-sleep cycle are involved in general anesthesia.

Background: Rumex nepalensis(RN) Spreng has been used to treat ulcer disease in Ethiopian folk medicine. This study aimed to determine the anti-ulcer activity of hydroalcoholic root crude extract and solvent fractions of in rats.
Methods: The effect of crude hydromethanolic extract and solvent fractions at doses (100, 200, 400 mg/kg/day) and repeated dosing (200 mg/kg/day for 10 and 20 days) was examined on ulcers in rats in pyloric ligation-, cold restraint stress-, and acetic acid-induced ulcer models.
