Stability of Tacrolimus Ophthalmic Solution. The main reason for this weak interaction between the drug and cyclodextrin may be the high molecular weight and the complex molecular structure of tacrolimus that hampered an adequate adaptation to the cyclodextrin cavity. Tacrolimus concentration, pH and osmolality stability of (a) TBS 40 and (b) TLI 40 stored under three different temperature conditions: in refrigeration (4 2 C), at room temperature (25 2 C) and at oven temperature (40 2 C) during a 4-month stability test. Molecular modeling of tacrolimus/HPCD interaction. In these STD spectra, the on-irradiation was placed in a certain proton signal of tacrolimus that is sufficiently separated in frequency from any HPCD signal to prevent them being directly saturated. An estimation of tacrolimus chemical stability during long-term storage can also be made: it would take approximatively 58 months for tacrolimus concentrations to decrease by 5% when stored at 5 C. The intimate contact and the presence of hydroxyl radicals in the polymer can promote the establishment of weak interactions with the mucin layer (i.e., hydrogen bonds) [82]. To ensure that it was not a tacrolimus degradation product, the different parts of the silicone membrane of the ophthalmic multidose device (Novelia.
