Growing evidence suggest that Alzheimer's disease (AD), the most common cause of dementia among the elderly is a metabolic disorder associated with impaired brain insulin signaling. Hence, the diabetic drug can be a therapeutic option for the management AD. The researches in this area are ongoing and Pioglitazone (PIO) is one of the most investigated diabetic drug in AD. Eventhough PIO treatment was found to improve AD significantly in the preclinical models, the poor blood-brain barrier (BBB) permeability and serious peripheral side effects limited its success in the clinical trials...

The purpose of this research was to develop a fiber optic (FO) dissolution method for quantification of multiple actives in combination pharmaceutical tablets. FO dissolution allows direct API quantification in the vessel, obviating the need for error-prone facets of traditional dissolution methods. However, FO dissolution is potentially challenged by overlapping UV spectra, matrix effects, UV-active excipients, API interactions with excipients and media, and undissolved components attenuating the UV signal...

Novel fatty acid-bile acid conjugates (1a-1k) were designed and synthesized by coupling of the fatty acids to the 3-OH of bile acids using lysine for linkage. In the conjugates, the 24-COOH of the bile acids was kept intact to preserve liver-specific recognition. The ability of the newly synthesized conjugates (at 100 mg/kg dosage) to reduce total cholesterol (TC) and triglyceride (TG) levels in mice fed with high-fat diet (HFD) was evaluated. Conjugates of stearic acid with cholic acid and palmitic acid with ursodeoxycholic acid (at dosages of 50, 100, and 200 mg/kg) were further evaluated to determine their ability to reduce aspartate aminotransferase (AST), alanine aminotransferase (ALT), TC, and TG levels in mice fed with HFD...

In the present study, in order to improve the solubility and bioavailability of poorly water-soluble dexibuprofen, a novel dexibuprofen-loaded solid dispersion was developed using the spray-drying technique. The controlled-release dexibuprofen formulation was developed by combining the immediate-release dispersion powder and the sustained-release formula. The solid dispersion composed of dexibuprofen/poloxamer 407/hydroxypropyl methylcellulose (HPMC) 2910 (50 cps)/sodium lauryl sulfate (SLS) (10/1/4/0.1 mg) was selected as the immediate-release formulation due to its increased solubility and dissolution rate...

Bicalutamide (BCT), an anticancer drug, suffers from dissolution rate limited bioavailability and poor micromeritic properties. Spherical crystallization involves formation of spherical agglomerates with enhanced dissolution properties, obviating the need of further granulation process. The present investigation was focused on spherical agglomeration of BCT by quasi emulsion solvent diffusion method. All the responses were subjected to principal component analysis to scrutinize the critical attributes. Further for optimization, X1; influence of phase ratio, X2; amount of PEG 6000 and X3; stirring speed on critical dependent variables was studied by employing the Box-Behken experimental design...

Pulmonary infections the most common cause of death globally. However, the development of mucosal vaccines that provide protective immunity against respiratory pathogens are limited. In contrast to needle-based vaccines, efficient vaccines that are delivered via non-invasive mucosal routes (such as via the lungs and nasal passage) produce both antigen-specific local mucosal IgA and systemic IgG protective antibodies. One major challenge in the development of pulmonary vaccines using subunit antigens however, is the production of optimal immune responses...
