Toward the eventual goal of developing highly stable CAMs, this study establishes a generalized framework that systematically relates elevated <i>T</i><sub>g</sub> values of CAMs to intermolecular interactions based on specific functional groups. CAMs were prepared via quench-cooling using various combinations of indomethacin, ketoprofen, flurbiprofen, flufenamic acid, aripiprazole, bifonazole, and clotrimazole. CAMs prepared with drugs containing the COOH group exhibited significant positive deviations from the <i>T</i><sub>g</sub> values predicted by the Gordon-Taylor equation (i.e., ideal mixing behavior). COOH-associated hydrogen bonding was determined to be a key factor for <i>T</i><sub>g</sub> elevation, with synergistic contributions from π-π interactions and halogen bonding. In CAMs exhibiting the largest <i>T</i><sub>g</sub> deviations, contributions from ionic bonding were crucial, and were likely favored by differences in the p<i>K</i><sub>a</sub> values of the constituent drugs. Continuity in <i>T</i><sub>g</sub> as a function of varying molar ratios indicated that stoichiometric pairing had a relatively minor contribution, while a decrease in the width of the glass transition suggested enhancement of molecular cooperativity as a possible mechanism for CAM stabilization. In contrast, non-COOH hydrogen bonding, π-π interactions, and halogen bonding on their own did not result in any meaningful <i>T</i><sub>g</sub> deviations from theoretical predictions.
