  • Patent number: 9744189
    Abstract: Lithium is regarded as the gold standard comparator and benchmark treatment for mania. One of the problems associated with Lithium is its narrow therapeutic window. Recent attempts to find new drugs with similar therapeutic activities have yielded new chemical entities. However, these potential new drugs have yet to match the many bioactivities attributable to lithium's efficacy for the treatment of neuropsychiatric diseases. Consequently, an intense effort for re-engineering lithium therapeutics using cocrystallization is currently underway. The evaluation of pharmacokinetics of previously unexplored lithium salts with organic anions (lithium salicylate and lithium lactate) has found that these lithium salts exhibit profoundly different pharmacokinetics compared to the more common FDA approved salt, lithium carbonate, in rats.

  • Patent number: 9662351
    Abstract: Despite its narrow therapeutic window, lithium is regarded as the gold standard comparator and benchmark treatment for mania. Attempts to find new drugs with similar therapeutic activities have yielded new chemical entities. However, these new drugs have yet to match the many bioactivities attributable to lithium's efficacy for the treatment of neuropsychiatric diseases. Consequently, an intense effort for re-engineering lithium therapeutics using crystal engineering is underway. The evaluation of pharmacokinetics of previously unexplored lithium salts with organic anions (i.e. lithium salicylate) has found that these lithium salts exhibit profoundly different pharmacokinetics compared to the more common FDA approved salt, lithium carbonate, in rats. Remarkably, lithium salicylate produced elevated blood and brain levels of lithium beyond 48 hours post-dose without the sharp peak that contributes to the toxicity problems of current lithium therapeutics.

  • Patent number: 8906414
    Abstract: Compositions and methods of increasing the bioavailability of catechins are presented. Compositions for increasing the bioavailability of catechins include compositions where the catechin is added to a solution of ethanol and water; compositions where the catechin is encapsulated within a nanoparticle; and compositions in which a nanoparticle complex is formed between the catechin and the nanoparticle. Each of these compositions was shown to increase bioavailability of EGCG and is useful in treating diseases such as Alzheimer's and HIV-associated dementia.
