The higher incidences of side effects of existing drugs have shifted researchers and clinicians to explore the dietary phytoconstituents for its therapeutic potentials. The present study is based on compression coated curcumin tablet for the colon. Curcumin has anti-inflammatory and antioxidant properties. Curcumin presents a bioavailability problem due to poor solubility. An inclusion complex ...

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...

Optical Coherence Tomography (OCT) and Terahertz pulsed imaging (TPI) are two powerful techniques allowing high quality cross-sectional images from within scattering media to be obtained non-destructively. In this paper, we report experimental results of using OCT and TPI for quantitatively characterizing pharmaceutical tablet coatings in the thickness range of 10—140 μm. We found that the spec...

The aim of this research was to investigate the technique for preparation of coated valproic acid and sodium valproate sustained-release matrix tablets. Different diluents were tested and selected as the effective absorbent for oily valproic acid. Effect of the amount of absorbent and hydroxypropylmethylcellulose on drug release from valproic acid-sodium valproate matrix tablets prepared with w...

The classic analysis by Anderson and Malone (Biophys J 14: 957-982, 1974) of the osmotic flow across membranes with long circular cylindrical pores is extended to a fiber matrix layer wherein the confining boundaries are the fibers themselves. The equivalent of the well-known result for the reflection coefficient sigma0 = (1 - phi)2, where phi is the partition coefficient, is derived for a peri...

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...

In the last few years, remarkable progress has been made in mobile consumer devices. Modern smartphones and tablet computers offer multi-core processors graphics processing units, which have opened up new application possibilities such as augmented reality, virtual 3D reconstruction. Augmented Reality (AR) is a key technology that going to facilitate paradigm shift way users interact with data ...

BACKGROUND Contact pressure of UHMWPE acetabular cup has been shown to correlate with wear in total hip replacement (THR). The aim of the present study was to test the hypotheses that the cup geometry, abduction angle, thickness and clearance can modify the stresses in cemented polyethylene cups. METHODS Acetabular cups with different geometries (Link: IP and Lubinus eccentric) were tested cy...

Drying is one of the widely used methods of food preservation and it is a sensitive food processing operation due to undesirable changes in the quality of dried product. In this study the effect of osmotic dyhedration and ultrasound pretreatment prior to convective drying on quality properties of apple slices was investigated. Apple slices were pretreated by osmotic dehydration in two concentra...
