Supersaturation in HIF showed to be stable up to a certain degree for different poorly soluble drugs. In HIF as well as in FaSSIF and FeSSIF, supersaturation appeared to be compound and medium specific. Supersaturation stability was found to be inversely proportional to the solubility in the corresponding media. Food intake affected itraconazole supersaturation positively. On the contrary, etravirine and loviride supersaturation decreased upon food intake. Supersaturation experiments in FaSSIF and FeSSIF showed similar results as in HIF for etravirine and loviride, whereas itraconazole supersaturation behaved differently in HIF versus simulation media. The present study illustrates, for the first time, that supersaturation can be created and maintained in HIF, even in the absence of excipients.
