Fig. 9From: Hot stage microscopy and its applications in pharmaceutical characterizationHSM micrograph showing lacidipine and PEG 10 mixture at different temperatures. a lacidipine/PEG 10 at 145 °C; b lacidipine/PEG 10 at 169 °C; c lacidipine/PEG 10 at 180 °C. Lacidipine begins to dissolve in molten PEG 10 which signifies that both are compatible with each other. Reprinted from Forster et al. 2001 with permission from the publisherBack to article page
