Benzenesulphonyl semicarbazides contg. heterocyclic acylamino groups attached to the benzene ring pref. in the para position, of general formula I possess oral anti-diabetic (blood sugar lowering) activity to a much greater degree than Tolbutamide. R'R"-isoxazolyl (or isothiazolyl or pyrazolyl) -(CH2)n -CO NRY.C6H4SO2-NH.CO.NH.NR3R4B where R = H or alkyl

A therapeutic tablet for lowering the blood sugar level comprises a slightly soluble hypoglycaemic sulphonyl urea compound and diotyl sodium sulphosuccinate. Specified sulphonyl urea compounds include those of general formula wherein R is methyl or chlorine, and R1 is alkyl, alicyclic, or heterocyclic e.g. tolbutamide, N-4-methyl-benzene sulphonyl-N1-cyclopentyl urea, N-4-methyl-benzene sulphonyl-N1-hexamethyleneimino urea. Inert non-caloric diluents may be added.

In a process for coating liquid or solid particles with a liquid polymer phase in non-aqueous solvent systems, the particles are dispersed in an organic solvent solution of the polymer, to which solution an organic non-solvent for said particles and said polymer is added, which non-solvent is miscible with said organic solvent, thereby causing the polymer to separate out from solution and deposit around the dispersed particles, a mineral silicate being intermittently added during the addition of...

A therapeutic tablet for lowering the blood sugar level comprises a sulphonyl urea compound of general formula wherein R is methyl or chlorine and R1 is an alkyl, alicyclic, or heterocyclic group, and polyvinyl pyrrolidone. Specified sulphonyl urea compounds are tolbutamide, N-4-methyl-benzenesulphonyl - N1 - cyclopentylurea and N-4-methyl - benzenesulphonyl - N1 - hexamethyleneimino urea. Polyvinyl pyrrolidone may be added as an aqueous solution to the sulphonyl urea comp...

The invention comprises compounds of the general formula in which (a) R1 and R2 are methyl, R, R3, R4 and R5 are H and n is 1

Membranes formed by the coacervation of a material comprising at least one gelable hydrophilic colloid having amino groups and peptide linkages (e.g. proteins and polyamines) are treated with an aqueous solution of an alum of general formula M1M111(S)2.12H2O wherein M1 is ammonium or a monovalent metal, M111 is a trivalent metal and S represents a sulphate or selenate radical. The membranes may be formed by simple or complex coacervation of one or more of the above colloids by any process on to ...
