Abstract: A process and new oxazolinic intermediates for the preparation of 4-(8-chloro-5,6-dihydro-11H-benzo-[5,6]-clohepta-[1,2-b]-pyridin-11-ylide-ne)-1-piperidinecarboxylic acid ethyl ester (loratadine) is described. The process starts from 2-(4,4-dimethyl-4,5-dihydrooxazol-2-yl)-3-methyl-pyridine, a new intermediate to obtain loratadine. 2-(4,4-dimethyl-4,5-dihydro-oxazol-2-yl)-3-methyl-pyridine is condensed with 3-chloro-benzyl-chloride and the resultant product is treated with Grignard reagent of 4-chloro-N-methyl-piperidine. [3-(2-(3-chloro-phenyl)-ethyl]-pyridin-2-yl-]-1-(methyl-piperidin-4-yl)-methanone is obtained for subsequent hydrolysis. Starting from this last compound it is possible to obtain loratadine with known methods.

Abstract: The invention concerns a MDF cement material showing better impact strength meant as an increase in the breaking total energy, by fibers addition.

Abstract: The invention relates to pharmaceutical compositions for parenteral administration. The compositions comprise an amount of neuromuscular blocking agent effective to produce muscular relaxation, and at least one zwitterionic substance having an isoionic point not greater than 7. The zwitterionic substance is present in an amount of between about 2 and about 30 percent by weight, based on the weight of the composition. The resulting composition has a pH of less than 7.

Abstract: Bioadhesive microemulsions or liposomic dispersions containing proteinaceous substances, especially calcitonin, that allow the systemic, local or topical administration of drugs by transmucosal route are described. This type of administration shows some considerable advantages of activity, tolerability, dosage individualization and drug stability.

Abstract: Liquid bioadhesive microemulsions or liposomic dispersions containing proteinic substances, especially calcitonin, that allow the systemic, local or topical administration of drugs by transmucosal route are described. This type of administration shows some considerable advantages of activity, tolerability, dosage individualization and drug stability. The compositions contain proteinic substances, and a polyoxyethylene-polyoxypropylene thermosetting copolymer. At body temperature the viscosity of the compositions is increased and provides increase residence time at the administration site.
