    Abstract: PURPOSE: To improve the bioavailability of L-686,708 which is poorly soluble to water although effective for the synthesis, action, and release inhibition of SRS-A, i.e., leukotriene in mammals, therapy of asthma, therapy of ocular inflammation, etc. CONSTITUTION: This complex is composed of a cyclodextrin and 3-[N-(p- chlorobenzyl)-3-(t-butylthio)-5-(quinolin-2-ylmethoxy)indol-2-yl]-2,2 dimethylpropanoic acid (L-686,708) sodium salt in the molar ratio of (1-5):1 (optimally, 2.5:1). This complex has bioavailability as high as 26 times that of a mere mixture of the cyclodextrin and the sodium salt as a result of improved solubility to water.
