Abstract

Centella asiatica (C. asiatica) is widely used in traditional medicine due to its numerous health benefits. Among its reputed advantages are improved memory, intelligence, and neural protection. Impairment of cognitive function as a center for memory processing occurs due to perinatal hypothyroidism. Although several studies have shown that C. asiatica extract may improve memory function, the effectiveness of its extract as a memory enhancer for patients with perinatal hypothyroid is less unknown. Therefore, this study aimed to determine the effects of ethanol extract of C. asiatica (EEC) leaf as a memory enhancer in perinatal hypothyroid mice model. C. asiatica leaves were extracted by the decoction method, and the ethanol extract was administered to mice. the hypothyroid mouse model was developed by administering antithyroid agents to pregnant mice from gestational day (GD) 18 to postnatal day (PND) 21. The hypothyroid mice were administered either donepezil 5 mg/kg BW/mL (positive control) or treatment group (EEC 2 mg/kg BW/mL) from PND 21 to PND 35 (14 days). The light-dark test (LDT) and memory tests of offspring were conducted on PND 36. We found that EEC improved the cognition and memory of perinatal hypothyroidism mice. This study contributes to the foundational research for developing memory-enhancing supplement preparations, mainly targeting children with perinatal hypothyroidism.

Abstract

Digoxin is a cardiac glycoside medication commonly used to control rapid heart rates in Atrial Fibrillation (AF). However, digoxin has a narrow therapeutic range and can be associated with adverse effects, including increased mortality risk, especially in the elderly. Pharmacokinetic changes occur with aging, affecting the way drugs are absorbed, distributed, metabolized, and eliminated from the body. Thus, this narrative review aimed to assess the optimization of digoxin dosing in elderly patients with AF while considering pharmacokinetic changes due to aging. We performed a comprehensive computerized search of relevant English articles and a manual examination of reference lists from primary sources formed the basis of this scoping review. This involved an extensive computerized search of relevant articles in English and a manual search of the reference lists of original articles. The review highlighted the need to carefully monitor digoxin levels in elderly patients due to changes in body composition, protein binding, hepatic clearance, renal excretion, and other factors affecting drug metabolism. Furthermore, we summarized guidelines and recommendations for optimizing digoxin dosing in elderly patients with AF. By shedding light on the intricacies of optimizing digoxin dosing in the elderly with atrial AF and emphasizing the significance of accounting for age-related pharmacokinetic changes, this review offers valuable insights for healthcare practitioners and researchers in the field. Addressing these aspects is crucial to enhancing therapeutic outcomes and minimizing potential risks associated with digoxin therapy in this vulnerable patient population

Abstract

Glyburide is a widely used oral antidiabetic agent for managing type 2 diabetes. Despite its long history, evolving insights into its pharmacokinetics (PK) and pharmacodynamics (PD) have highlighted knowledge gaps, especially in the context of genetic variability, drug-drug interactions, and use in special populations. This narrative scoping review synthesizes recent evidence to provide a comprehensive and updated understanding of glyburide’s PK/PD profiles.  A thorough literature search of studies published in English, including manual reference checks, was conducted. Glyburide exhibits complex pharmacokinetics, extensive absorption throughout the gastrointestinal tract, significant plasma protein binding, hepatic metabolism via CYP2C9 and CYP3A4 enzymes, and predominantly renal elimination. Its pharmacodynamic effects involve stimulating insulin secretion and enhancing peripheral insulin sensitivity. Common side effects include hypoglycemia and weight gain, while drug-drug interactions and monitoring are crucial for safe and effective use. Understanding glyburide’s pharmacokinetics and pharmacodynamics is key to optimizing diabetes management. Tailoring dosages based on patient factors can improve efficacy, minimize adverse effects, and enable personalized care. Further research on genetic influences, drug interactions, and its use in special populations is needed to refine treatment strategies and enhance safety and effectiveness.
