Abstract
Lipid-based formulations (LBFs) are isotropic mixtures typically comprising lipids, surfactants, and/or co-solvents, in which drugs are pre-solubilized. After oral administration, LBFs are piggybacked into endogenous lipid digestion pathways. This triggers drug super-saturation and improves absorption. However, super-saturation poses a risk of drug precipitation, which generally leads to poor drug absorption. Furthermore, a series of aqueous colloidal species including digestion products (typically fatty acids and monoglycerides) and endogenous molecules (bile acids and phospholipids) increase the drug solubilization capacity of the intestinal fluid (compared with that of the normal intestinal fluid). However, the solubilization/precipitation behavior may change according to the LBF composition (e.g., the drug loading amount and type of formulation excipients), which may ultimately lead to differences in oral absorption. This review summarizes the results of the evaluation and prediction of the effect of LBFs composition on oral absorption and provides an in-depth understanding of the drug absorption mechanisms when using LBFs.

Abstract
PURPOSE To investigate the compatibility between hard gelatin and HPMC capsules with a range of different isotropic lipid based formulations containing multiple excipients. METHODS The miscibility was investigated for 350 systems applying five different oils (Labrafac ™ lipophile WL1349, Maisine® CC, Captex 300 EP/NF, olive oil, and Capmul MCM EP/NF), five different surfactans (Labrasol ® ALF, Labrafil M 2125 CS, Kolliphor ® ELP, Kolliphor ® HS 15, Tween 80) and three different cosolvents (propylene glycol, polyethylene glycol 400, and Transcutol ® HP). For the isotropic systems capsule compatibility was investigated in both gelatin and HPMC capsules at 25°C at 40% and 60% relative humidity by examining physical damages to the capsules and weight changes after storage. RESULTS The miscibility of lipid based vehicles was best when the formulation contained monoglycerides and surfactants with a hydrophilic-lipophilic balance value <12. Gelatin capsules in general resulted in a better compatibility when compared to HPMC capsules for the evaluated formulations. Addition of water to the formulation improved the capsule compatibility for both capsule types. The expected capsule mass change could partly be predicted in binary systems using the provided data of the single excipients weighted for its formulation proportion. CONCLUSIONS The capsule compatibility was driven by the components incorporated into the formulations, where more was compatible with gelatin than HPMC capsules. Prediction of the mass change from individual excipient contributions can provide a good first estimate if a vehicle is compatible with a capsule, however, this needs to be proved experimentally.

Abstract
![]()
The concept of using
precipitation inhibitors (PIs) to sustain
supersaturation is well established for amorphous formulations but
less in the case of lipid-based formulations (LBF). This study applied
a systematic in silico–in vitro–in vivo approach to assess the merits of
incorporating PIs in supersaturated LBFs (sLBF) using the model drug
venetoclax. sLBFs containing hydroxypropyl methylcellulose (HPMC),
hydroxypropyl methylcellulose acetate succinate (HPMCAS), polyvinylpyrrolidone
(PVP), PVP-co-vinyl acetate (PVP/VA), Pluronic F108,
and Eudragit EPO were assessed in silico calculating
a drug–excipient mixing enthalpy, in vitro using a PI solvent shift test, and finally, bioavailability was
assessed in vivo in landrace pigs. The estimation
of pure interaction enthalpies of the drug and the excipient was deemed
useful in determining the most promising PIs for venetoclax. The sLBF
alone (i.e., no PI present) displayed a high initial drug concentration
in the aqueous phase during in vitro screening. sLBF
with Pluronic F108 displayed the highest venetoclax concentration
in the aqueous phase and sLBF with Eudragit EPO the lowest. In vivo, the sLBF alone showed the highest bioavailability
of 26.3 ± 14.2%. Interestingly, a trend toward a decreasing bioavailability
was observed for sLBF containing PIs, with PVP/VA being significantly
lower compared to sLBF alone. In conclusion, the ability of a sLBF
to generate supersaturated concentrations of venetoclax in
vitro was translated into increased absorption in
vivo. While in silico and in vitro PI screening suggested benefits in terms of prolonged supersaturation,
the addition of a PI did not increase in vivo bioavailability.
The findings of this study are of particular relevance to pre-clinical
drug development, where the high in vivo exposure
of venetoclax was achieved using a sLBF approach, and despite the
perceived risk of drug precipitation from a sLBF, including a PI may
not be merited in all cases.

Abstract
PURPOSE Lipid-based formulations (LBF) have shown oral bioavailability enhancement of lipophilic drugs, but not necessarily in the case of hydrophobic drugs. This study explored the potential of lipid vehicles to improve the bioavailability of the hydrophobic drug nilotinib comparing a chase dosing approach and lipid suspensions. METHODS Nilotinib in vivo bioavailability in rats was determined after administering an aqueous suspension chase dosed with blank olive oil, Captex 1000, Peceol or Capmul MCM, respectively. Absolute bioavailability was determined (relative to an intravenous formulation). Pharmacokinetic parameters were compared to lipid suspensions. RESULTS Compared to the lipid suspensions, the chase dosed lipids showed a 2- to 7-fold higher bioavailability. Both long chain chase dosed excipients also significantly increased the bioavailability up to 2-fold compared to the aqueous suspension. Deconvolution of the pharmacokinetic data indicated that chase dosing of nilotinib resulted in prolonged absorption compared to the aqueous suspension. CONCLUSION Chase dosed LBF enhanced the in vivo bioavailability of nilotinib. Long chain lipids showed superior performance compared to medium chain lipids. Chase dosing appeared to prolong the absorption phase of the drug. Therefore, chase dosing of LBF is favourable compared to lipid suspensions for 'brick dust' molecules such as nilotinib. Graphical Abstract The potential of bio-enabling lipid vehicles, administered via chase dosing and lipid suspensions, has been evaluated as an approach to enhance oral bioavailability of nilotinib.

Abstract
PURPOSE Lipid suspensions have been shown to be a suitable bio-enabling formulation approach for highly lipophilic or 'grease ball' drug molecules, but studies on 'brick dust' drugs are lacking. This study explored the utility of lipid suspensions for enhancing oral bioavailability of the rather hydrophobic drug nilotinib in vivo in rats. METHODS Four lipid suspensions were developed containing long chain triglycerides, medium chain triglyceride, long chain monoglycerides and medium chain monoglycerides and in vivo bioavailability was compared to an aqueous suspension. Additionally, in vitro lipolysis and wettability tests were conducted. RESULTS Nilotinib lipid suspensions did not show a bioavailability increase compared to an aqueous suspension. The bioavailability was lower for triglyceride suspensions, relative to both monoglyceride and an aqueous suspension. The long chain monoglyceride displayed a significantly higher bioavailability relative to triglycerides. In vitro lipolysis results suggested entrapment of nilotinib crystals within poorly dispersible triglycerides, leading to slower nilotinib release and absorption. This was further supported by higher wettability of nilotinib by lipids. CONCLUSION Monoglycerides improved oral bioavailability of nilotinib in rats, relative to triglycerides. For 'brick dust' drugs formulated as lipid suspensions, poorly dispersible formulations may delay the release of drug crystals from the formulation leading to reduced absorption. Graphical Abstract An aqueous and four lipid suspensions have been evaluated in in vitro and in vivo to gain insights into the potential benefits and limitations of lipid suspensions.

Abstract
The objective of this work was to design and characterize liquid and solid self-emulsifying drug delivery systems (SEDDS) for poorly soluble atorvastatin. To optimize the composition of liquid atorvastatin-SEDDS, solubility tests, pseudoternary phase diagrams, emulsification studies and other in vitro examinations (thermodynamic stability, droplet size and zeta potential analysis) were performed. Due to the disadvantages of liquid SEDDS (few choices for dosage forms, low stability and portability during the manufacturing process), attempts were also made to obtain solid SEDDS. Solid SEDDS were successfully obtained using the spray drying technique from two optimized liquid formulations, CF3 and OF2. Despite liquid SEDDS formulation, CF3 was characterized by lower turbidity, higher percentage transmittance and better self-emulsifying properties, and based on the in vitro dissolution study it can be concluded that better solubilization properties were exhibited by solid formulation OF2. Overall, the studies demonstrated the possibility of formulating liquid and solid SEEDS as promising carriers of atorvastatin. SEDDS, with their unique solubilization properties, provide the opportunity to deliver lipophilic drugs to the gastrointestinal tract in a solubilized state, avoiding dissolution—a restricting factor in absorption rate of BCS Class 2 drugs, including atorvastatin.

Abstract
PURPOSE To investigate if drug solubility in pharmaceutical excipients used in lipid based formulations (LBFs) can be predicted from physicochemical properties. METHODS Solubility was measured for 30 structurally diverse drug molecules in soybean oil (SBO, long-chain triglyceride; TGLC), Captex355 (medium-chain triglyceride; TGMC), polysorbate 80 (PS80; surfactant) and PEG400 co-solvent and used as responses during PLS model development. Melting point and calculated molecular descriptors were used as variables and the PLS models were validated with test sets and permutation tests. RESULTS Solvation capacity of SBO and Captex355 was equal on a mol per mol scale (R (2) = 0.98). A strong correlation was also found between PS80 and PEG400 (R (2) = 0.85), identifying the significant contribution of the ethoxylation for the solvation capacity of PS80. In silico models based on calculated descriptors were successfully developed for drug solubility in SBO (R (2) = 0.81, Q (2) = 0.76) and Captex355 (R (2) = 0.84, Q (2) = 0.80). However, solubility in PS80 and PEG400 were not possible to quantitatively predict from molecular structure. CONCLUSION Solubility measured in one excipient can be used to predict solubility in another, herein exemplified with TGMC versus TGLC, and PS80 versus PEG400. We also show, for the first time, that solubility in TGMC and TGLC can be predicted from rapidly calculated molecular descriptors.
