Joseph A., Raj D., Shanmuganathan V., Powell R.J., Dua H.S. The Bovine Corneal Opacity and Permeability test (BCOP), which allows to detect whether the tested compounds cause a moderate, severe or very severe irritation, combined with the hens egg test on the chorioallantoic membrane assay (HETCAM) covers the whole spectrum of irritation, since mild or very mild irritation signs can be detected. The resulting data showed no statistically significant differences between all the formulations; however, significant differences ( < 0.05) were observed between the studied formulation and the positive control (ethanol). Likewise, hypertonic topical ophthalmic formulations may alter the tear osmolarity and, thus, induce ocular inflammation, as described by Dutescu et al. Tukeys multiple comparison test was also performed, and no statistically significant differences were found between the TLI 20 and TLI 40 formulations, but significant differences were observed between the rest of the formulations ( < 0.05). The determination of tacrolimus was performed as previously mentioned (see Section 2.1.1. Preparation of Tacrolimus loaded micelles based on poly(-caprolactone)poly(ethylene glycol)poly(-caprolactone).

One- and Two-Stage Arrhenius Models for Pharmaceutical Shelf Life Prediction. Tacrolimus solubility with 20%, 30% and 40% (w/v) of HPCD in Balanced Salt Solution (BSS) and Liquifilm vehicles. The platinum du Nuy ring was washed with alcoholic KOH, rinsed in MilliQ water and flamed until red-hot before each measurement. The rigid doughnut-shaped structure makes it a natural complexing agent, being able to form inclusion complexes with several drugs, where their structure (or part of it) may fit in the cyclodextrin cavity [39]. Tacrolimus ophthalmic micellar solutions at 0.2 mg/mL and 1 mg/mL are physicochemically stable for up to nine months when stored at 5 C, but additional studies are still needed to evaluate in-depth the containercontent interactions that were detected, especially the impact of a compound leaching out of the used eyedropper bottle. A solubility study was carried out by adding an excess amount of the tacrolimus powder to MilliQ aqueous solutions containing increasing concentrations of HPCD (from 0 to 400 mg/mL). The experiment consisted of a selective saturation pulse train, a WET selective solvent suppression module and a 90-degree hard-pulse followed by fid (free induction decay) acquisition. Do not save this mixture for later use. Nevertheless, statistically significant differences were observed ( < 0.05) between 20% (w/v) HPCD formulations and 40% (w/v) HPCD formulations as well as between 40% (w/v) HPCD formulations and REF for times beyond 30 min post-administration. Visual aspect, colour, turbidity, micelle size and viscosity all remained unchanged through the study, as did the pH and osmolality of the solutions. An HPCD molecule type with an average of four hydroxypropyl groups per native CD unit was used to obtain the molecular model.

A.F.-F. acknowledges the support received from the Instituto de Salud Carlos III (ISCIII) through its Juan Rodes grant (JR18/00014). Therefore, in the case of the designed formulations (TBS 20, TLI 20, TBS 40 and TLI 40), the surface tension values were slightly higher than physiological parameters, but they were still at an optimal value (see Table 2). Surface tension at the surface-to-air interface was measured using the du Nuy ring method [50]. The selective saturation consisted of a train of soft Gaussian-shaped pulses of 50-ms duration with a 1-ms interpulse delay. The development of new ophthalmic topical vehicles for increasing drugs permanence on the ocular surface is important to improve drug bioavailability in the eye as well as the treatment adherence by patients [81]. The value of K1:2 is often lower than that of K1:1. ; Investigation: M.B., Y.L.B. This process may cause irreversible tissue damage and visual impairment. Tam P.M.K., Young A.L., Cheng L.L., Lam P.T.H. Jin, S.-E.; Jeon, S.; Byon, H.-J. Adding HPCD to formulations, apart from increasing the solubility and stability of tacrolimus, also gave a more viscous and stickier characteristic to the solution. The mean volume of a drop was determined to be 25.0 L and 25.7 L, respectively, for the 1 mg/mL and 0.2 mg/mL formulation, with the density being of 0.9815 and 0.98805. During the simulated test, an additional peak appeared in the 1 mg/mL tacrolimus drops emitted from the eyedroppers. Besides, high doses may cause the patient to suffer from side effects, while underdosing may cause damage or prolonged drug therapy. In a similar way, the osmolality of the 1 mg/mL formulation did not vary by more than 7.06% (54.25 mOsm/kg) and 7.25% (55.75 mOsm/kg) of the initial mean osmolality during the nine months of storage at, respectively, 5 C and 25 C and no more than 10.8% (83 mOsm/kg) during the six months of storage at 35 C.
