	Treatment of brain injury due to gray matter edema with (indanyloxy) butanoic acids - Patent 4465850
		The invention relates to the treatment and prevention of injury to the gray matter of the brain and to the spinal chord due to accidents, ischemic stroke, cardiac arrest, arrested breathing, Reye's syndrome and hydrocephalus by the administration of (indanyloxy)butanoic acids, their derivatives, analogs and salts thereof.
		The butanoic acid is dissolved in water (800 ml) containing a slight excess of N-methylpiperazine, filtered and treated with ice and slight excess of 10N sodium hydroxide.
		The (+) 4-[(2-butyl-6,7-dichloro-2-cyclopentyl-2,3-dihydro-1-oxo-1H-inden-5-yl)oxy ]butanoic acid is reduced to a No. 60 powder and then lactose and magnesium stearate are passed through a No. 60 bolting cloth onto the powder and the combined ingredients admixed for 10 minutes and then filled into a No. 1 dry gelatin capsule.
