This invention provides liposomic composition, containing as active ingredient (-)-N-.alpha.-dimethyl-N-(2-propynylphenylethylamine) (selegilin) and/or salt thereof. This composition contains: 0.1-40% by weight of selegilin and/or a salt thereof, 2 to 40% by weight of lipids, preferably phospholipids, 0 to 10% by weight of cholesterol, 0 to 20% by weight of an alcohol, 0 to 25% by weight of a glycol, 0 to 3% by weight of an antioxidant, 0 to 3% by weight of a preserving agent, 0 to 2% by weight of a viscosity influencing agent, 0 to 50% by weight of cyclodextrin or a cyclodextrin derivative and 30 to 90% by weight of water. This invention relates to pharmaceutical composition, containing the liposomic composition described and if desired, usual filling and diluting agents and other auxiliaries, preferably in oral, parenteral or transdermal form. This invention provides the process for the preparation of liposomic compositions containing selegilin and/or salt thereof. Accordingly liposomic composition of this invention may be administered for the treatment of Alzheimeir's disease, Parkinson's disease, depression, stroke, motion sickness or myelitis.

The invention relates to two phase pharmaceutical compositions comprising as active ingredient a MAO inhibitor and an uptake inhibitor together with usual pharmaceutical auxiliaries. The compositions can be used for the treatment of neurodegenerative diseases. As active ingredient optionally N-(1-phenyl-isopropyl)-N-methyl-propinylamine or N-(4-fluoro-phenyl)-isoprop-1-yl-N-methyl-propinylamine or their salts, optically active isomers or metabolites are used both as MAO inhibitor and as uptake inhibitor.

The invention relates to inclusion complexes of N-ethoxycarbonyl-3-morpholino-sydnonimine or its salts formed with a cyclodextrin derivatives, preparation thereof and pharmaceutical compositions containing the same. The inclusion complex of N-ethoxycarbonyl-3-morpholino-sydnonimine or its salt formed with cyclodextrin derivative is prepared by a) reacting the N-ethoxycarbonyl-3-morpholino-sydnonimine or its salt and the cyclodextrin derivative in a solvent medium, and if desired recovering the complex from the solution by dehydration, or b) high energy milling of the N-ethoxycarbonyl-3-morpholino-sydnonimine or its salt and the cyclodextrin derivative.

The invention relates to inclusion complexes of 3-morpholino-sydnonimine or its salts or its tautomer isomer, process for the preparation thereof and pharmaceutical compositions containing the same. The inclusion complex of 3-morpholino-sydnonimine or its salt formed with cyclodextrin derivative is prepared by a) reacting the 3-morpholino-sydnonimine or its salt in an aqueous medium with a cyclodextrin derivative and the complex is isolated from the solution by dehydratation, or b) high energy milling of 3-morpholino-sydnonimine or its salt and a cyclodextrin derivative.

The invention relates to novel compounds of the general formula (I), ##STR1## The compounds of the invention antagonize the effects of constrictive mediators, e.g. histamine, acetylcholine or serotonin; they show an antiallergic action and possess an antiinflammatory effect. Thus, these compounds can therapeutically be used as bronchodilators as well as antiallergic or antiinflammatory drugs, particularly in the treatment of bronchial asthma.
