DESIGN AND EVALUATION OF ORO – FLASH RELEASE FILMS OF AMLODIPINE BESYLATE
This work aimed to formulate amlodipine besylate Oro flash release films by solvent casting method. Various film forming polymers like Hydroxy propyl methyl cellulose (HPMC) E5, HPMC E15, sodium carboxymethyl cellulose, sodium alginate, xanthan gum were used and out of which HPMCE5 was found to be satisfactory. Propylene glycol was used as plasticizer at a range of 13-32%w/w of the film and 31%w/w...

CLINICAL EVALUATION OF A NEW FORMULATION OF 99mTc-TRODAT-1 FOR SPECT IMAGING IN PARKINSON PATIENTS AND VOLUNTEER SUBJECTS
This study was conducted to evaluate the clinical usefulness of new developed kit of 99mTc-TRODAT-1 to differentiate PD(Parkinson disease) from volunteer subjects. The 925-1111MBq (25-30 mCi) 99mTc-TRODAT-1 samples were reconstituted by boiling water bath method. Fourteen subjects (women = 6, men = 8, age range 24 - 72, mean = 54.4) have been participated in this approach. The control group includ...

DENDRIMERS FOR DRUG SOLUBILITY ENHANCEMENT– A REVIEW
Sufficient fluid solvency has been one in everything about required properties while choosing drug particles and completely uncommon bio-actives for advancement. Here and there dissolvability of a medication decides its pharmaceutical and remedial execution. Most of these days organized medicine IOTAS miss the mark or are rejected for the length of the main times of drug disclosure and improvement...

ISRADIPINE ENHANCES THE ANTICONVULSANT ACTIVITY OF CARBAMAZEPINE AGAINST MES AND PTZ INDUCED CONVULSIONS IN RATS
The aim of this study was to investigate the possible anticonvulsant effect of a Dihydropyridine calcium antagonist, Isradipine, which easily crosses the blood–brain barrier displaying high affinity and specificity for the brain L-type voltage-sensitive calcium channel, on maximal electroshock seizures and PTZ induced seizures. The seizures were induced in rats by maximum electroshock method and...

FORMULATION AND DEVELOPMENT OF BOSENTAN LOADED ONCE A DAILY TABLET FOR PULMONARY ARTERY HYPERTENSION USING LIPID MATRICES BY 32 FULL FACTORIAL DESIGN
To avoid problems of conventional therapy of drug delivery and reduced dose, sustained release matrix tablet of Bosentan was prepared using lipid base material as matrices. Primary screening of polymer was done by selecting different lipid base materials like Compritol 888 ATO, Precirol ATO 5, Eudragit RSPO, Glycerly monostearate (GMS) and cetosteryl alcohol. All the batches were prepared by direc...

SOLUBILITY AND DISSOLUTION ENHANCEMENT OF POORLY AQUEOUS SOLUBLE DRUG GEFITINIB BY SELF EMULSIFYING DRUG DELIVERY SYSTEM
The present research work was aimed at the enhancement of solubility and dissolution rate of Gefitinib by Self Emulsifying Drug Delivery Systems (SEDDS). Gefitinib is a BCS class II drug with poor aqueous solubility (oral bioavailability 60%). The saturated solubility of Gefitinib in different oils, surfactants and co-surfactants were determined. The excipients were screened and selected showing m...
