Development of new oral cyclosporine formulation using cyclodextrin tetrapolymer (Pαβγ-CD) in attempt to enhance its stability and dissolution rate.Two spray-dried dispersion formulations containing poorly water-soluble cyclosporine (CsA) were prepared with cyclodextrin tetrapolymer in water (FH2O) and ethanol (FEOH) then characterized by scanning electron microscopy, powder X-ray diffraction, ...

The discovery and use of cyclosporine since its inception into clinical use in the late 1970s has played a major role in the advancement of transplant medicine. While it has improved rates of acute rejection and early graft survival, data on long-term survival of renal allografts is less convincing. The finding of acute reversible nephrotoxicity and nephrotoxicity in nonrenal transplants has si...

Interpatient differences in the kinetics of cyclosporine appear to result in part from interindividual differences in the catalytic activity of an enzyme termed P450 3A. We investigated the relationship between P450 3A activity, as measured by the erythromycin breath test (ERMBT), and the appropriate stable daily dose of cyclosporine as currently determined by physicians at our institution. The...

The objective of this study was to compare the binding of cyclosporine to blood proteins between four healthy subjects and five liver and eight renal transplant patients. Fresh heparinized blood was obtained, to which sufficient quantities of tritium-labelled cyclosporine and unlabelled cyclosporine were added to blood samples or red blood cell (RBC) suspensions. Concentrations of cyclosporine ...

Background & Aims: Hypertension, hyperuricaemia and nephrotoxicity are some common side-effects of Cyclosporine A (CsA) treatment in renal transplant recipients. Previous studies suggest that Calcium Channel Blockers (CCB) can increase serum level of CsA and may improve graft function in patients receiving CsA. The aim of this study was to evaluate the effects of Diltiazem and Amlodipine on cyc...

conclusions the lee is a common finding among kidney transplant recipients. serial monitoring of aminotransferases, particularly alt, should be performed in all patients after kidney transplantation. patients and methods liver enzymes and other biochemical parameters were measured in all recipients. patients were divided into three groups, according to laboratory test time since transplantation...

Cyclosporine is an effective drug in acute exacerbations of corticosteroid resistant ulcerative colitis, but its efficacy to maintain disease remission is not clear. Cyclosporine may not be as effective in Crohn's disease. However, being a rapidly acting immunosuppressant, cyclosporine may be a valuable therapeutic option in the short-term to treat corticosteroid resistant Crohn's disease and u...

PURPOSE This investigation was performed to evaluate the effect of cyclosporine alone and in combination with nifedipine on gingival overgrowth. METHODS One hundred and nineteen patients who had undergone renal transplantation at least 12 months previously were selected for the study. The patients were divided into 2 groups according to whether they had received cyclosporine alone (group 1, n...
