Drug Delivery Systems and Formulation Platforms

LATITUDE offers its clients proprietary drug delivery technologies derived from our many years of experience as drug formulators. These innovative dosage forms, which have patents issued or pending, can solve your formulation challenges as well as provide new intellectual property for your API.


LATITUDE’s latest drug delivery technology is a powerful yet safe, broad-spectrum solubilizer called ClearSol™.  The ClearSol™ vehicle forms stable, one-phase aqueous solutions with about 80% of insoluble APIs tested, which is much greater than achieved by other solubilizers such as cyclodextrins (e.g., sulfobutyl ether beta-cyclodextrin), polysorbates, and organic solvents.  Furthermore, ClearSol™ formulations can be freely diluted in water or IV infusion fluids without any precipitation of the API, and can be sterile-filtered through standard 0.2-micron filters.  ClearSol™ is made up of three Generally Regarded As Safe (GRAS) excipients that are FDA-approved for injection, and safety of the ClearSol™ technology has been demonstrated in several animal models and a U.S. Phase 1 human clinical trial under an FDA-approved IND.  Details on the ClearSol™ technology can be found here.
