A new drug delivery system for H2 receptor antagonist Ranitidine hydrochloride, was developed utilizing both the concepts of adhesiveness and of flotation, in order to obtain a unique drug delivery system which could remain in the stomach for a much longer period of tim Floating-Mucoadesive tablets of Ranitidine hydrochloride were developed to prolong its release and improve bioavailability. Ra...

A rapid, simple, sensitive and selective analytical method was developed by using reverse phase ultra performance liquid chromatographic technique for the simultaneous estimation of bambuterol hydrochloride and montelukast sodium in combined tablet dosage form. The developed method is superior in technology to conventional high performance liquid chromatography with respect to speed, resolution...

A stability-indicating reversed-phase high performance liquid chromatography (RP-HPLC) method was developed for the determination of betaxolol hydrochloride, a drug used in the treatment of hypertension and glaucoma. The desired chromatographic separation was achieved on a Nucleosil C18, 4 μm (150 × 4.6 mm) column, using isocratic elution at a 220 nm detector wavelength. The optimized mobile ph...

A new simple high performance thin layer chromatographic method for simultaneous determination of antidiabetic drugs, metformin hydrochloride and sitagliptin phosphate in bulk and tablet dosage form were investigated. Chromatographic separation of the drugs were performed on aluminum plates precoated with silica gel 60 F254 as the stationary phase and the solvent system consisted of acetone:met...

A series of pyridine-bridged 2,6-bis-carboxamide Schiff's bases has been prepared starting from 2,6-pyridinedicarbonyl dichloride (1) and L-alanine or 2-methyl-alanine methyl ester.The coupling of acid chloride 1 with L-alanine methyl ester hydrochloride -or 2-methylalanine methyl ester hydrochloride gave the corresponding 2,6-bis-carboxamide pyridine methyl esters 2a,b.Hydrazonolysis of 2 with...

The quantitative analysis of tizanidine hydrochloride in both pharmaceutical dosage form and bulk medication has been developed validated using an easy, affordable, quick, unique isocratic HPLC approach. Tizanidine was separated isocratically Waters symmetry C18 ODS as the stationary phase (250×4.6 mm, 5μm particle size), a flow rate 1.0 ml/min, UV detector to track eluate at 230 nm. drug its d...

A new apoprotein has been isolated from delipidated human very low density lipoproteins by Sepharose 6B chromatography in 6 Y guanidine hydrochloride. This water-insoluble protein was noted to be unique to the plasma very low density and chylomicron fractions. This protein was shown to be homogeneous by urea-DEAE-cellulose chromatography, rechromatography in a guanidine-Sepharose system, sodium...

This work describes a novel L-lactate biosensor based on the immobilization of dehydrogenase enzyme screen-printed electrode modified with ternary composite gold nanoparticles, electrochemically-reduced graphene oxide, and poly (allylamine hydrochloride). The was stabilized by crosslinking glutaraldehyde. Applied working potential, pH NAD+ concentration were optimized. reports specific sensitiv...

In man amiloride hydrochloride (MK-870) has been shown to be an orally effective diuretic which causes a positive potassium balance. It also enhances the saluretic effects of hydrochlorothiazide and ethacrynic acid and in addition prevents the negative potassium balance caused by these diuretics (Wilson et al., 1966; Gombos et al., 1966). Gombos et al. also studied its effects in 10 hypertensiv...

This study has selected the medium-chain saturated fatty acid pelargonic as raw material for first time, and added surface catalyst Tween 80 to aqueous solution form acid–Tween composite vesicles by a tension method. The compound vesicle was used encapsulate five heterocyclic drugs (cefazolin sodium, chlorpromazine hydrochloride, gemcitabine metronidazole, isoniazid), all of which have disadvan...
