Abstract
Experiments have been performed which test the stability of thymoxamine in aqueous solution at room temperature and above. It was determined that dimethyl-beta-cyclodextrin slows the hydrolysis degradation of thymoxamine while other beta-cyclodextrin analogs either accelerate the hydrolysis degradation or have no effect on the rate of hydrolysis degradation. Cytological experiments have been performed which show that chemical formulations containing thymoxamine and up to 5% by weight dimethyl-beta-cyclodextrin have the same toxicity as chemical formulations with thymoxamine alone.
