Abstract: Optically active naphthyl alpha-substituted alkyl ketones, are a class of ketones useful as intermediates in the production of optically active alpha-naphthylalkanoic acids which exhibit anti-inflammatory, analgesic and anti-pyretic activity.

Abstract: A non-stinging aqueous anti-inflammatory steroid formulation suitable for intranasal administration comprises: an anti-inflammatory steroid in an amount between about 0.01% and about 0.05% (w/v); propylene glycol in an amount between about 2% and about 10% (w/v); PEG 400 in an amount between about 10% and about 25% (w/v); polysorbate 20 in an amount between about 1% and about 4% (w/v); an effective amount of a preservative; an effective amount of a stabilizer; an effective amount of an antioxidant; water; and pH buffering agent sufficient to adjust the pH of the resulting solution to between about 3.5 and about 7.

Abstract: This invention concerns a new process of preparing optically active .alpha.-arylalkanoic acids and their precursors. These .alpha.-arylalkanoic acids, esters, amides, nitriles, oxazolines and metal salts are stereoselectively prepared by forming the metal or metal halide of the corresponding acid, ester, amide, oxazoline, nitrile, or metal salt and treating the compound so prepared with an aryl halide in the presence of a chiral (optically active) transition metal catalyst of the formula (LL*)QZT wherein Q is a transition metal selected from palladium and nickel; Z and T are independently halogen; and LL* is a chiral tertiary diphosphine compound capable of acting as a bidentate ligand with Q to form a 5-membered ring, optionally in the presence of a dipolar aprotic solvent or mixtures thereof, for a time sufficient to form the corresponding optically active .alpha.

Abstract: Pharmaceutically useful optically active .alpha.-arylalkanoic acids or esters, ortho esters, or amides thereof are stereoselectively prepared by contacting an aryl magnesium Grignard reagent with an optically active .alpha.-substituted acyl halide to form the optically active aryl .alpha.-substituted alkyl ketone, which is ketalized and rearranged to the desired optically active .alpha.-arylalkanoic acid or the corresponding ester, ortho ester or amide. In an alternate embodiment, the aryl .alpha.-substituted alkyl ketone is reduced to the corresponding alkanol, which is rearranged to the .alpha.-arylalkanal. The alkanal so produced is converted to the desired optically active .alpha.-arylalkanoic acid by conventional methods.

Abstract: A method of contraception and a pharmaceutical package for effecting the method are disclosed. The method comprises a three phase sequence of estrogen/progestogen administration which is a daily sequence of unit dosages over a repeating cycle, which dosage sequence comprises, for one cycle:(a) administering, as phase one, about 20-40 .mu.g of ethinyl estradiol, (or of other estrogen in an amount sufficient to result in an equivalent effect) and about 0.3-0.8 mg of norethindrone (or of other progestogen in an amount sufficient to result in an equivalent effect) each day for 5-8 days, followed by;(b) administering, as phase two, the same dosage of estrogen and twice the dosage of progestogen each day as was administered each day in phase one, for 7-11 days, followed by;(c) administering, as phase three, the same dosage of estrogen and the same dosage of progestogen each day as was administered each day in phase one, for 3-7 days, followed by;(d) administering, as phase four, no therapeutically active dosage, i.
