ODTs are becoming increasingly important in the pharmaceutical market, both for prescription and over-thecounter medications, and can significantly enhance patient compliance. As they can be swallowed without the need for water, these dosage forms are particularly convenient for children and the elderly, and they’re the delivery format of choice for people who want to take their medicine ‘on th...

Chitosan is a cationic natural polysaccharide which is derived from the chitin of crustaceans, with crabs and shrimp-shell wastes as its principal source. Its properties includes extent of deacetylation and the average molecular weight of polymer as well as low toxicity and good bioavailability make it a novel excipient in pharmaceutical formulation as a relatively new development. Together wit...

a substantially lower number of drug formulations containing new molecular entities (NMEs) in the past decade (1). In 2008, the agency approved formulations containing 21 NMEs and four biologics, slightly higher than the 2007 total of 17 NMEs and two biologics. The growth between 2007 and 2008, however, was not enough to counter the marked downward spiral of drug approvals during the past 10 ye...

These are additives used to convert pharmacologically active compounds into pharmaceutical dosage forms suitable for administration to patients [1]. Although excipients are the non-active ingredients, they are essential in the successful production of acceptable solid dosage forms such as tablets and powders. For example, the lack of filling materials would make it exceedingly challenging, if n...

This work studied artemether (ARTM) solid dispersion (SD) formulation using mixture of polymer excipient Soluplus, PEG 400, Lutrol F127, and Lutrol F68 melts at temperatures lower than the melting point of ARTM using a laboratory-size, single-screw rotating batch extruder. The effects of three surfactants PEG 400, Lutrol F127, and Lutrol F68 and parameters like mixing temperature, screw rotatin...

in t ro du C t io n Pharmaceutical dosing vehicle excipients such as Triton X-100 are often added to formulations to facilitate dissolution in dosing media. Unfortunately, these compounds can cause significant matrix effects, typically ion suppression, in LC/MS/MS analyses. The use of fast LC gradients, common in drug discovery, can result in co-elution of target analytes with these compounds. ...

The incorporation of different cyclodextrin (CD) excipients such as HPbeta-CD, beta-CD, gamma-CD or alpha-CD into polymer millirods for complexing beta-lapachone (beta-lap), a potent anti-cancer drug, significantly improved the drug release kinetics with various drug release patterns. However, such a complex system requires a mechanistically based model in order to provide a quantitative unders...

Background Doxorubicin (DOX) is an effective chemotherapeutic agent but severe side effects limit its clinical application. Nanoformulations can reduce the toxicity while still have various limitations, such as complexity, low drug loading capability and excipient related concerns. Methods An amphiphilic conjugate, doxorubicin-dichloroacetate, was synthesized and the corresponding nanoparticl...

The aim of this study was to develop and optimize a segregation-free ethyl cellulose-coated extended release multiparticulate formulation to be compressed into tablets without affecting the drug release. Standard tableting excipients (e.g., microcrystalline cellulose, lactose or sorbitol) were layered onto ethyl cellulose-coated propranolol hydrochloride pellets to form a cushion layer in order...

The polyherbal decoction, Gulugulutitakam is known for the treatment of various inflammatory conditions. For the ease of administration, this dosage form has been converted into tablets containing high amount of dry extract but it has the disadvantage of longer disintegration and dissolution parameters. In our attempt to develop tablets with improved disintegration and dissolution time, we have...
