Effect of honey on plasma concentration of diltiazem after oral and intravenous administration in rabbits, has been studied. For oral study, single dose of diltiazem (5 mg/kg, p.o.) along with saline was administered to New Zealand white rabbits (n=8). Blood samples were collected at 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6 and 8 hr after drug administration from marginal ear vein. After a washou...

a mixture of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride is used for the symptomatic treatment of common cold. in this study, a derivative spectrophotometric method based on zero-crossing technique was proposed for simultaneous determination of acetaminophen, diphenhydramine hydrochloride and pseudoephedrine hydrochloride. determination of these drugs was perf...

The effect of pretreatment with graded concentration of diltiazem on the inotropic responses to amrinone were studied on isolated atria of rabbit. The responses to amrinone were modified by diltiazem in a biphasic manner; initial potentiation followed by inhibition. The potentiation is proposed to be due to synergistic rise in cytosolic calcium ion concentration by diltiazem and amrinone. The i...

An in vivo study has been carried out to evaluate the synergism of diltiazem and nifedipine on the antihypertensive activity and the effect of ketotifen fumerate and potassium nitrate on this phenomenon of synergism in rabbit. It has been found that the lowering of blood pressure by concurrent administration of diltiazem and nifedipine was not equal to the sum of lowering of blood pressure by i...

Article history: Received on: 02/03/2015 Revised on: 12/04/2015 Accepted on: 03/05/2015 Available online: 27/07/2015 The aim of this study is to investigative the stability of poly(ethylene oxide) (PEO) matrix tablets containing diltiazem hydrochloride (DTZ) after five-year storage at room temperature. DTZ matrix tablets containing different molecular weights (MW) of PEO and electrolytes (sodiu...

The main objective of the present study was to develop matrix-moderated transdermal systems of Diltiazem HCl using various proportions of Ficus reticuleta fruit mucilage. Physical evaluation was performed such as moisture content, moisture uptake, tensile strength, flatness and folding endurance. In-vitro penetration studies were performed in a Keshary-Chien diffusion cell. The matrix-type tran...

The present investigation describes the design and evaluation of monolithic gastro retentive dosage forms of diltiazem. Hydrophilic cellulose derivatives, Sodium alginate, Sodium carboxy methyl cellulose, Polyox, Methocel K100M in combination with Methocel E6LV are used as the rate controlling polymers. Sodium bicarbonate was incorporated as gas generating agent. Tablets were prepared by employ...

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...
