Type 2 diabetes is a leading cause of morbidity and mortality among non-communicable diseases and additional animal models that more closely replicate the pathogenesis of human type 2 diabetes are needed. The goal of this study was to develop a model of type 2 diabetes in guinea pigs in which diet-induced glucose intolerance precedes β cell cytotoxicity, two processes that are critical to the development of human type 2 diabetes. Guinea pigs developed impaired glucose tolerance after eight weeks of feeding a high fat, high carbohydrate diet, as determined by oral glucose challenge...

PURPOSE: Current practices applied to mouse pharmacokinetic (PK) studies often use large numbers of animals with sporadic or composite sampling that inadequately describe PK profiles.  The purpose of this work was to evaluate and optimize blood microsampling techniques coupled with dried blood spot (DBS) and LC-MS/MS analysis to generate reliable PK data in mice.  In addition, the feasibility of cross-over designs was assessed and recommendations are presented. METHODS: The work describes a comprehensive evaluation of five blood microsampling techniques (tail clip, tail vein with needle hub, submandibular, retro-orbital, and saphenous bleeding) in CD-1 mice...

PURPOSE: To investigate whether weight change in the first year after initiating an oral hypoglycemic agent (OHA) for type 2 diabetes treatment is associated with mortality in a national cohort. PROCEDURES: We prospectively followed Veterans Health Administration patients with type 2 diabetes initiating treatment with an OHA and not receiving any other diabetes pharmacotherapy for at least one year. Information on OHAs, weight, co-morbidities, other medications, demographics, and laboratory measurements was obtained from electronic medical records...

OBJECTIVE: This review focuses on hypoglycemia in patients with end stage renal disease (ESRD). It discusses pathophysiology of glucose metabolism in the kidney, the impact of dialysis on glucose and insulin metabolism and the challenges of glucose monitoring in ESRD. The clinical relevance of these changes are reviewed in relation to altered blood glucose targets and modification of antidiabetes therapy to prevent hypoglycemia. Based on current data and guidelines, recommendations for the outpatient and inpatient setting are provided for diabetes management in ESRD...

Despite the substantial body of research investigating the use of liposomes, niosomes and other bilayer vesicles for drug delivery, the translation of these systems into licensed products remains limited. Indeed, recent shortages in the supply of liposomal products demonstrate the need for new scalable production methods for liposomes. Therefore, the aim of our research has been to consider the application of microfluidics in the manufacture of liposomes containing either or both a water soluble and a lipid soluble drug to promote co-delivery of drugs...

Ingestion of sulfonylureas is life-threatening in toddlers and children due to its strong and prolonged hypoglycemic effect. The authors present a 15-mo-old boy with accidental ingestion of Glipizide who presented with encephalopathy, seizure and severe hypoglycemia. The management included parenteral dextrose and octreotide administration to maintain euglycemia, followed by complete neurological recovery within 24 h. Sulphonylurea intoxication should be considered in previously healthy toddlers and children presenting with hypoglycemia especially if any caregiver is on sulfonylurea drugs...

An 8-yr-old male golden lion tamarin ( Leontopithecus rosalia ) was diagnosed with diabetes mellitus based on hyperglycemia and persistent glycosuria. Initial treatment consisted of the oral antihyperglycemic medications glipizide and metformin that resulted in decreased blood glucose concentrations; however, marked glycosuria persisted. Insufficient improvement on oral antihyperglycemic therapy and poor feasibility of daily subcutaneous insulin therapy led to an investigation into an alternative therapy with extended-release exenatide, a glucagon-like peptide-1 (GLP-1) mimetic, at a dosage of 0...

In the present work, a simple, rapid and reliable ultra high performance liquid chromatography -tandem mass spectrometric (UHPLC-MS/MS) method was developed and validated to simultaneously determine epalrestat (EPA) and puerarin (PUE) in rat plasma for evaluation the pharmacokinetic interaction of this two drugs. Both the analytes and glipizide (IS) were extracted using protein precipitation method. The separation was performed on C18 reversed phase column using acetonitrile and 5 mmol/L ammonium acetate in water as mobile phase with a gradient elution program...

BACKGROUND: It is unclear whether people with type 2 diabetes mellitus on insulin monotherapy who do not achieve adequate glycaemic control should continue insulin as monotherapy or can benefit from adding oral glucose-lowering agents to the insulin therapy. OBJECTIVES: To assess the effects of insulin monotherapy compared with the addition of oral glucose-lowering agents to insulin monotherapy for people with type 2 diabetes already on insulin therapy and inadequate glycaemic control...

OBJECTIVE: Many Emergency Medicine Services (EMS) protocols require point-of-care blood glucose testing (BGT) for any pediatric patient who presents with seizure or altered level of conscious. Few data describe the diagnostic yield of BGT when performed on all pediatric seizures regardless of presenting mental status. We analyzed a large single center dataset of pediatric patients presenting with prehospital seizures to determine the prevalence of hypoglycemic seizures and the utility of repeat BGT in the emergency department (ED)...

OBJECTIVE: Stimulation of the ß-cell metabolism by glucose and other fuels triggers insulin release by enhancing the mitochondrial ATP production and acutely amplifies the secretory response by increase in mitochondrial export of metabolites. We aimed to narrow down the uniform final reaction steps mediating fuel-induced acute amplification of insulin secretion. MATERIAL/METHODS: Insulin secretion and metabolic parameters were measured in isolated mouse islets exposed to the sulfonylurea glipizide in high concentration (closing all ATP-sensitive K(+) channels) during the entire experiment...

Spray dried dispersions (SDDs) of glipizide, a BCS Class II model drug, were prepared using various grades of hydroxypropyl methylcellulose acetate succinate (HPMCAS) and copovidone S-630 as carriers. The SDDs appeared as a single amorphous phase with up to 60% drug loading level as revealed by X-ray powder diffraction (XRPD), modulated differential scanning calorimetry (mDSC) and scanning electron microscopy (SEM). Supersaturated micro-dissolution testing of various SDDs in fasted state simulated intestinal fluid showed prolonged supersaturation state (up to 180min) with solubility increases of 5...

Among various metabolic disorders, diabetes mellitus is one of the most common disorder. Present study was designed to evaluate the effectiveness of aqueous extract of Bauhinia variegata leaves (AE) in animal models of type I and type II diabetes. Type I diabetes was induced by streptozotocin at the dose of 55mg/kg (i.p.) in male Sprague Dawley rats while type II diabetes was induced by high fat diet and streptozotocin at the dose of 35mg/kg (i.p.). Diabetic animals were treated with AE at the dose of 250, 500 and 1000mg/kg...

In this study, the amorphization of glipizide was systematically investigated through high-energy ball milling at different temperatures. The results of solid-state amorphization through milling indicated that glipizide underwent direct crystal-to-glass transformation at 15 and 25°C and crystal-to-glass-to-crystal conversion at 35°C; hence, milling time and temperature had significant effects on the amorphization of glipizide, which should be effectively controlled to obtain totally amorphous glipizide. Solid forms of glipizide were detailedly characterized through analyses of X-ray powder diffraction, morphology, thermal curves, vibrational spectra, and solid-state nuclear magnetic resonance...

This case report outlines a very rare case of glipizide-induced severe proximal myopathy in a 61-year-old diabetic man. After taking 10 mg glipizide for 5 months, diabetes was well controlled but the patient presented with progressive proximal muscle weakness in all the four limbs. Clinical examination and relevant investigations suggested it to be a case of proximal myopathy and might be drug induced. De-challenge was done and was treated resulting in reversal of the diseased state. After 3 more months, controlled re-challenge was done and there was recurrence of proximal muscle weakness...
