This invention relates to an improvement comprising coating agitated particles of substantially anhydrous antacid with a solvent-free mixture of electronegatively charged material in a non-toxic inert substantially water insoluble oil.

Dry oil coated antacid process

Simethicone is entrapped in solid, discrete particles of a matrix composition of glycerol and corn syrup solids. A mixture of these particles and a therapeutic antacid overcomes the incompatability of the simethicone and the antacid, due to the shielding action of the matrix composition.

Medicinal simethicone containing composition and its method of production

This invention describes a method of lowering the viscosity of aqueous gels of agents used in pharmaceutical preparations and of aqueous suspensions used as pharmaceutical preparations. Particular gels and suspensions and the viscosity lowering ingredients which are most useful are also described.

Method for lowering the viscosity of certain agents

A therapeutic composition of methaqualone and the like quinazolinone compounds or their acid addition salts per se or in combination with other therapeutic agents, said composition containing solubilizing adjuncts and being rapidly and readily absorbed, and methods of making and using same.
