Abstract: The present application relates to compositions which influence the central nervous system and which are especially useful in the treatment of hyperkinesis and rigidity. These compositions contain as active ingredient 1,3-dimethyl-5-aminoadamantane in the form of the free base or a pharmaceutically-acceptable salt thereof, together with a methylxanthine compound, e.g., caffeine or theophylline, in an amount up to about fifteen milligrams of the methylxanthine compound per each milligram of the 1,3-dimethyl-5-aminoadamantane compound. These compositions are useful in the treatment of central nervous system disorders, particularly of Parkinson's disease, depressions, spasticity, rigidity, hyperkinesis, and the like. The compositions possess unpredictable beneficial properties of a synergistic nature. The application also relates to the treatment of such central nervous system ailments or conditions with a combination of the said two active agents either concurrently or together in the same dosage form or unit.

Abstract: Certain 1,3,5-trisubstituted adamantane compounds having central nervous system activity, especially anti-Parkinsonism activity, method of preparing same, and pharmaceutical compositions thereof, method of influencing the central nervous system therewith.

Abstract: The application discloses a novel improved process for the production of .alpha.-[2-(p-chlorophenoxy)-isobutyl]-.beta.-nicotinoyl glycol ester, a known compound having a lipid-lowering effect, by the reaction of .alpha.-[2-chlorophenoxy)-isobutyryl]-.beta.-ethyl chloride ester with an alkali salt of nicotinic acid, preferably sodium nicotinate, preferably in a high-boiling polar or dipolar aprotic solvent, especially dimethylformamide, most preferably at a temperature of about 120.degree. - 180.degree. C., and most advantageously in refluxing dimethylformamide. An unpredictable increase in yields of the desired product over yields attainable by previously-available processes is thereby obtained.

Abstract: A spermicidally-active suppository having advantageous properties comprising spermicide, a water-soluble polyethylene glycol suppository base, foaming agent, and foam-stabilizing agent, having a relatively low percentage by weight of foam-developing agent, wherein the spermicide is in alkylphenoxypolyethoxyethanol, the suppository base comprising about 65 to 85 percent by weight of a water-soluble polyethylene glycol which is meltable at body temperature, and the foaming agent comprising about 10 to 20 percent by weight of a mixture of tartaric acid and sodium bicarbonate, and a method of producing the same, are disclosed.
