Abstract: A two layered cleansing tablet for the self-acting cleansing of dentures. The layers of the tablet disintegrate at controlled rates so that denture cleansing action is made more efficient and effective compared to single layered tablet structures. The present tablet employs sulfonic acid in the tablet layer which disintegrates in a first stage cleansing step and further employs ethylene diamine tetraacetate in both tablet layers. Improved denture cleansing action is achieved even with no increase in the total amount of active agents employed in a tablet.

Abstract: A fast-acting (3-5 min.) denture-cleansing tablet for use in aqueous solutions to automatically clean dentures is comprised of a mixture containing gas-forming materials, organic and inorganic calcium bonding materials, oxidizing materials, surfactant materials, carriers, lubricants and flavoring materials. Fast cleansing action and short decomposition times are obtained by including amidosulfonic acid, ethylene diamine tetraacetic acid, dialkyl thiourea, and a non-ionogenic fluorochemical material in an amount sufficient to achieve a pH in a 1% solution of such formulation in water of 6.3 to 6.5.

Abstract: Therapeutic antihypertensive compositions containing N-(2,6-dichlorophenyl)-4,5-dihydro-1H-imidazol-2-amine and N-(2-chloroethyl)-N-(1-methyl-2-phenoxyethyl)benzenemethanamine or their non-toxic, pharmaceutically acceptable salts are described as well as a method of reducing blood pressure in mammals.
