Commercial tablets of Rosuvastatin Calcium exhibit unsatisfactory dissolution profiles and, consequently, problems of absorption and poor bioavailability. Rosuvastatin Calcium (RST), a poorly water-soluble 3-hydroxy3-methyl glut aryl CoA (HMG-CoA) Reductase inhibitor through inclusion complexation with hydroxy propyl β-cyclodextrin (HP-β-CD). The aim of this work was to develop Rosuvastatin Oro...

The intention of present research is to formulate and develop the meclizine hydrochloride fast dissolving tablets using sublimation method to enhance the dissolution rate. In this study an attempt was made to fasten the drug release from the oral tablets by incorporating the superdisintegrants and camphor as sublimating agent. The prepared fast dissolving tablets were subjected to precompressio...

The object of this study was to develop hydroxypropyl methylcellulose (HPMC) based cephalexin extended release tablet, which can release the drug for six hours in predetermined rate. Twenty-one batches of cephalexin tablets were prepared by changing various physical and chemical parameters, in order to get required theoretical release profile. The influences of HPMC, microcrystalline cellulose ...

Purpose: Triple solid dispersion adsorbates (TSDads) and spherical agglomerates (SA) present new techniques that extensively enhance dissolution of poorly soluble drugs. The aim of the present study is to hasten the onset of hypoglycemic effect of glimepiride through enhancing its rate of release from tablet formulation prepared from either technique. Methods: Drug release from TSDads or SA tab...

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 purpose of this research was to develop gastro-retentive delivery system of atenolol which, after oral administration should have the ability to prolong gastric residence time with desired in vitro release profile. Atenolol was chosen as a model drug because it is poorly absorbed from the lower gastrointestinal tract. The tablets were prepared by direct compression technique, using natural ...

OBJECTIVE Intentional and accidental drug intoxication is commonly seen in the emergency department. When treating intoxicated patients, accessing the amount of the ingested drug is crucial albeit often difficult. We investigated the accuracy of estimating tablet counts when participants were asked to hold tablets in their fists and hands (semi-quantitative terms). METHODS The widths and leng...

      Calcium acetate is used as an oral phosphate binder to control hyperphosphatemia in patients with chronic renal failure. Compared to calcium carbonate, control of hyperphosphatemia can be achieved at lower calcium administration with calcium acetate which likely reduces the risk of hypercalcemia. In this study, various formulations of calcium acetate tablets were prepared and their disint...

In the past decade, many strategies have been developed to enhance oral drug delivery. Different techniques were investigated, amongst those the use of permeation enhancers such surfactants and biodegradable polymers were studied more extensively. Chitosan derivatives have been studied as permeation enhancer in free soluble form and as nanoparticulate systems. The aim of the current work wa...

Anxiety is feeling of danger in a person who is threatening with something. Nowadays, anxiety is increased in different populations and, thus it is became an important problem in many countries. Melissa officinalis (Melissa) and Valeriana officinalis (Valerian) are two medicinal plants. These two plants are traditionally used as sedative herbal drugs and new studies on their pharmacological act...
