The most effective agent was 2-hydroxypropyl-β-cyclodextrin (2HPCD) which solubilized alfaxalone in a linear manner as a function of concentration. At a 2HPCD concentration of 50% w/v, approximately 80 mg/mL of alfaxalone was dissolved indicating an increase in aqueous solubility of over four orders of magnitude. The cyclodextrin solution was stable to autoclaving and could be conveniently lyophilized to yield a solid product.
