PREVENTION OF ACCUMULATED TOLERANCE TO STIMULANT MEDICATION FOR THE TREATMENT OF ADHD
It is proposed that dissipation of relative benefit during long-term treatment is due to long-term tolerance to stimulant medications. To improve adherence and persistence of medication use, it is advantageous to develop medications that are not undermined by long-term tolerance. Disclosed herein in certain implementations are formulations and methods relating to an alternative formulation of medication for the treatment of ADHD based on two principles: (a) retaining the initial immediate-release component of controlled-release formulations that targets a neural mechanism, which elicits acute tolerance, and (b) replacing the subsequent sustained-release component with a medication that maintains the initial benefit by targeting a different neural mechanism does not elicit tolerance, thus allowing more time for acute tolerance elicited by the initial bolus dose of stimulant medication to dissipate completely each day and avoid carry-over and accumulation that results in long-term tolerance.

POROUS SILICATE/MAGNETIC FERRITE NANOCARRIER FOR COMBINATION ANTI-CANCER THERAPEUTIC AND ANTIOXIDANT DELIVERY
A nanomedicinal composition comprising a nanocarrier and a pharmaceutical agent mixture comprising an anti-cancer therapeutic and an antioxidant. The nanocarrier comprises a porous silicate matrix and particles of a magnetic ferrite disposed in the pores of the porous silicate matrix. The pharmaceutical agent mixture is disposed in the pores and/or on the surface of the nanocarrier by a solution phase impregnation process. The nanomedicinal composition is used in a method of treating breast cancer.

Starch-based release modifying excipients and pharmaceutical compositions derived therefrom
There is provide an extended release dosage form comprising a release modifying excipient comprising high amylose starch, cross-linked hydroxypropylated amylopectin, and a pre-gelatinized common starch; wherein the release modifying excipient is substantially free of crosslinks between amylose and amylopectin and substantially free of crosslinks between amylose and amylose. It has been found that the extended release properties of conventional cross-linked high amylose starches (e.g., Contramid®) can be reproduced by intimately mixing i) cross-linked chemically modified amylopectin; ii) a high amylose, non-chemically modified starch and; iii) a pre-gelatinized common starch. Producing a release modifying excipient in this way means that no chemical cross linking between (a) amylose and amylopectin or (b) amylose and amylose has occurred—properties heretofore considered vital for Contramid® function. The release modifying excipient blends overcome problems associated with use of Contramid, and provide a flexible platform for formulation of active pharmaceutical ingredients for controlled release applications.
