Objective: The objective of the present work was to formulate a gastroretentive dosage form of Valacyclovir, an anti viral drug. Methods: Valacyclovir gastroretentive mucoadhesive tablets were prepared using polymers such as Carbopol 974P and hydroxy propyl methyl cellulose (HPMC) K4M, in different proportions by wet granulation technique. Compatibility studies were performed by FTIR spectrosco...

The purpose of the study was to prolong the gastric residence time and increase the bioavailability of atenolol by designing its floating tablets and to study the influence of different polymers on its release rate. It was selected as a model drug, because it is poorly absorbed from the lower GIT. The tablets were prepared by direct compression technique, using different polymers such as hydrox...

The aim of the present work was to develop a gastroretentive floating tablet of Atenolol and investigate the effects of both hydrophilic and hydrophobic retardant on in vitro release. Atenolol is an antihypertensive drug with an oral bioavailability of only 50% because of its poor absorption from lower gastrointestinal tract. The floating tablets of Atenolol were prepared to increase the gastri...

Venlafaxine is a unique antidepressant that differs structurally from other currently available antidepressants. Short biological half life, low bioavailabilty and frequent administration of drug led rational for development of extended release formulation of Venlafaxine that releases the drug and maintian the plasma drug concentration for more than 12h.Polymers like Hydroxy propyl methyl cellu...

Bi-layered [1] tablet refers to tablet which contain subunits. In bi-layer [2] tablets, one layer tablet provides immediate release and the other layer acts as sustained release. Sumatriptan is a new class of anti-migraine [3] drugs that selectively activate 5-HT1B/1D receptors and are called triptans. Our objective is to formulate and evaluate the bi-layer tablets of sumatriptan succinate of d...

A baby full term born of LSCS to a otherwise healthy mother was referred for ophthalmology department. On ophthalmological torch light examination, the patient had equal upper and lower lid bilateral ectropion. There missing eye lashes noted. The anterior segment evaluation found be within normal limit without evidence corneal opacities. Lamellar ichthyosis termed as Collodion is infrequent dis...

Edible films and coatings in foods can be used to increase shelf-life and improve organoleptic characteristics of foods by avoiding deterioration of food components and therefore promoting preservation of the final product. This study is the first to investigate the use of different size fillers for the purpose of preparing edible composite films with fillers < 1.0 microm in size. For this purp...

in recent years, great efforts have been devoted to the design of drug delivery systems. many polymeric excipients have been studied in order to make drug release fit the desired profiles. the aim of this work was to design a theophylline oral suspension, as sustained release pharmaceutical preparation in order to decrease the plasma level fluctuations and adverse effects of theophylline. micro...

The main aim of this study was preparation and evaluation of extended - release system ofthe anxiolytic substance. Alprazolam is a short-acting benzodiazepine with general propertiessimilar to those of diazepam. Our studies focused on development of extended drug deliverysystem based on Hydroxy Propyl Methyl Cellulose (HPMC 4000cps) as retard agent andPolyvinylpyrrolidone (PVP k30) as binder us...

The goal of this study was to design and evaluate extended - release system of the hypnotic agent, Zolpidemtartrate usefulness for the treatment of insomnia. The half-life of this drug is about 1.9 - 3 hours that indicatingit a candidate for the extended release formulation. Our investigation relates to development of extendeddrug delivery system based on Hydroxy propyl methyl cellulose (HPMCK4...
