Nicorandil is a new antianginal agent that potentially may be used to treat the cardiovascular side effects of diabetes. It is both a nitric oxide donor and an opener of ATP-sensitive K(+) (K(ATP)) channels in muscle and thereby causes vasodilation of the coronary vasculature. The aim of this study was to investigate the domains of the K(ATP) channel involved in nicorandil activity and to deter...

Nicorandil, a drug approved for the treatment of ischaemic heart disease, is believed to have a dual properties. The intrinsic mechanism of the drug (selective activation of KATP channels at the sarcolemmal and mitrochondrial level) allows coronary and peripheral vasodilatation with subsequent reduction of preload and afterload. Secondly, because of the role KATP channels in ischaemic precondit...

Nicorandil is a medication used for treatment and prevention of angina pectoris. Its mode of action involves both arterial and venous vasodilation. Although there are numerous known side effects, one of the more unusual, adverse reactions is ulceration of the external genitalia. This case reports the finding of penile preputial ulceration secondary to the use of Nicorandil. The authors make som...

The purpose of this study was to obtain a nicorandil pulsatile release tablet that has a well-regulated release lag time. When nicorandil is used as an antiangina drug, administration time control is important. A pulsatile release tablet is one of the effective approaches to modified release to reduce daily administration frequency. In this study, a pulsatile release tablet of nicorandil was fo...

In guinea-pig cardiomyocytes, a cAMP-dependent Cl(-) current (I(Cl,cAMP)) flows through a cardiac isoform of the cystic fibrosis transmembrane conductance regulator (CFTR), which belongs to a family of the ATP-binding cassette (ABC) proteins. Although several K(+)-channel openers and sulfonylurea ATP-sensitive K(+) (K(ATP))-channel blockers reportedly inhibit I(Cl,cAMP), effects of nicorandil o...

The association of the anti-anginal drug nicorandil with oral and anal ulceration is becoming more widely recognised, but there are no reports of isolated nicorandil-induced rectal ulceration. Awareness of this condition is poor, and patients often undergo unnecessary surgery for a condition which resolves on stopping the medication.We report a case of nicorandil-induced rectal ulceration causi...

OBJECTIVES The purpose of this study was to determine whether ATP-sensitive potassium (K(ATP)) channel agonists exert a beneficial effect on the structural, functional, and molecular features of the remodeling heart in infarcted rats. BACKGROUND Myocardial K(ATP) channels have been implicated in the ventricular remodeling after myocardial infarction by inhibition of 70-kDa S6 (p70S6) kinase. ...

BACKGROUND Contrast-induced nephropathy (CIN) remains to be a potentially serious complication of radiographic procedures and is the third leading cause of the acute kidney injury (AKI) among hospitalized patients. This clinical trial was performed to assess the preventive effect of oral nicorandil on CIN in high-risk patients undergoing cardiac catheterization. METHODS In this prospective, r...

OBJECTIVE As an important prognostic factor of coronary artery bypass grafting (CABG), graft vasospasm can be observed in all currently used graft conduits. Radial artery (RA) vasospasm is more prone to occur in comparisons with internal mammary artery (IMA) and great saphenous vein (GSV). There is still controversy about which antispasmodic agent is superior to different grafts, especially to ...

Nicorandil, an adenosine triphosphate (ATP)-sensitive potassium (K(ATP)) channel opener, has been shown to exert a significant protective effect against ischemic heart injury. In the present study, we investigated the anti-apoptotic effects of nicorandil on rat mesenchymal stem cells (MSCs) subjected to hypoxia and serum deprivation (H/SD), as well as the potential underlying mechanisms. Apopto...
