-
, (2022/03/31)
There is disclosed an oral pharmaceutical composition for the treatment of multiple diseases comprising a denatonium cation salt and a sour anion selected from the group consisting of acetate (DA), citrate (DC) tartrate (CT), maleate (DM) and combinations thereof (collectively “denatonium salt”) and pharmaceutical excipients for gastric release of the denatonium salt. There is further disclosed an oral immediate release pharmaceutical composition to substantially release an API (active pharmaceutical ingredient) in the gastric area of the GI tract formulation, wherein the API comprises an effective amount of the denatonium salt. Preferably, the oral immediate release pharmaceutical formulation comprises from about 0.5 g to about 5 g of the denatonium salt delivering a daily dose of the denatonium salt from about 20 mg to about 150 mg to a human adult.

PREPARATION OF A QUATERNARY AMMONIUM HYDROXIDE AND USE THEREOF FOR THE PREPARATION OF Q QUATERNARY AMMONIUM SALT

Page/Page column 6; 7, (2008/06/13)
The invention relates to a process for the preparation of a quaternary ammonium hydroxide, in particular denatonium hydroxide, and the use thereof for the preparation of a quaternary ammo nium salt, in particular of denatonium benzoate or a denatonium fatty acid derivative. Due to its extremely bitter taste, this latter compound is applied in the art as an aversive agent, biocide, antifoulant and flavorant. It is usually prepared from a quaternary ammonium halide in an organic environment, which after isolation and purification is converted to a hygroscopic and unstable hydroxide intermediate, which in turn is immediately converted to the salt of interest in the solvent in which it is prepared. It is now found that these isolation steps can be avoided by performing the reaction at aqueous conditions. This is more straightforwardly and does not require costly precaut ions to avoid contact while handling. Moreover, the process of the invention allows to produce the quaternary ammonium salt from a lignocaine compound in a one-pot synthesis involving mostly water.
