there are many reports for involvement of atp-sensitive potassium channels in pancreatic, cardiac and vascular smooth muscle cells. this study examined the effect of single doses of k+ channel openers diazoxide, minoxidil and k+ channel blockers chlorpropamide, glibenclamide on serum concentration of aldosterone in male rats. blood samples were obtained 60 minutes after drug treatment and serum...
background: renal ischemia reperfusion (ir) injury has been a major source of concern during the past decades and angiotensin converting enzyme (ace) inhibitors have been successfully used to prevent this injury. there have been some controversial reports about the involvement of katp channels in the mechanism of action of ace inhibitors. in this study, we examined the effect of katp channel bl...
objective(s): electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. the leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. the aim of this study is to research the effect of atp-dependent potassium (katp) channel blocker (gl...
The characteristics of specific binding of the ATP-sensitive K(+) (K(ATP)) channel blocker [3H]glibenclamide to forebrain membranes (P(2) fraction, 4 degrees C) obtained from morphine-naive and -tolerant mice were evaluated. Morphine tolerance was induced by osmotic minipumps that released 45 mg/kg/day of morphine subcutaneously for 6 days. This treatment enhanced the antinociceptive ED(50) of ...
OBJECTIVE To compare the efficacy and safety profile of adding inhaled human insulin (INH) (Exubera) or glibenclamide to metformin monotherapy in patients with poorly controlled type 2 diabetes. RESEARCH DESIGN AND METHODS We conducted an open-label, parallel, 24-week multicenter trial. Patients uncontrolled on metformin were randomized to adjunctive INH (n = 243) or glibenclamide (n = 233). ...
Sulfonylurea derivatives glibenclamide and tolbutamide are selective blockers of ATP-sensitive K+ (KATP) channels. However, their ability to prevent cellular K+ loss and shortening of action potential duration during ischemia or hypoxia in the intact heart is modest compared with their efficacy at blocking KATP channels in excised membrane patches. In the isolated arterially perfused rabbit int...
Sulfonylurea and glinide drugs display different effects on insulin granule motion in single beta-cells in vitro. We therefore investigated the different effects that these drugs manifest towards insulin release in an in vivo long-term treatment model. Diabetic GK (Goto-Kakizaki) rats were treated with nateglinide, glibenclamide or insulin for 6 weeks. Insulin granule motion in single beta-cell...
Background: Glibenclamide is a lipophilic drug widely used in type 2 diabetes treatment. However, its low bioavailability limits its use. Thus, novel formulations should be applied to improve the drug’s bioavailability. Objectives: This study aimed to develop alternative carriers for oral delivery of glibenclamide. For this purpose, two biocompatible polymers, poly(e-caprolactone) and poly(but...
background: medicinal plants with biologically active components such as antioxidant and antidiabetic are useful sources of novel therapeutics. in iran, traditionally believed that the aqueous extract of berberry fruit (berberis integerima f.) improved health, especially in people with diabetes. objective: in this study, in vitro phytochemical and antioxidant activities of b. integerrima and b....
an environmentally benign rp-hplc approach for rapid analysis of glibenclamide in pure form, developed nanoemulsion and commercial tablets was developed and validated in present investigation. the green chromatographic identification was performed on lichrosphere 250 x 4.0 mm rp c8 column having a 5µm packing as a stationary phase using a combination of ethanol: methanol (50:50 % v/v) as a mobi...
