Strategies to Address Low Drug Solubility in Discovery and Development
The article provides an integrated and contemporary discussion of current approaches to solubility and dissolution enhancement but has been deliberately structured as a series of stand-alone sections to allow also directed access to a specific technology where required. Expand
Incomplete desorption of liquid excipients reduces the in vitro and in vivo performance of self-emulsifying drug delivery systems solidified by adsorption onto an inorganic mesoporous carrier.
It is indicated that solidification of lipid-based formulations through adsorption onto a high surface area carrier may limit formulation (and drug) release in vivo and thereby reduce oral bioavailability. Expand
Lipid-based formulations solidified via adsorption onto the mesoporous carrier Neusilin® US2: effect of drug type and formulation composition on in vitro pharmaceutical performance.
Although Neusilin® is an effective vehicle for LBF solidification, its use is accompanied by a risk of incomplete desorption of the vehicle from the carrier, irrespective of the drug. Expand
Toward the establishment of standardized in vitro tests for lipid-based formulations, part 1: method parameterization and comparison of in vitro digestion profiles across a range of representative
The Lipid Formulation Classification System Consortium is an industry-academia collaboration, established to develop standardized in vitro methods for the assessment of lipid-based formulationsExpand
Lipid digestion as a trigger for supersaturation: evaluation of the impact of supersaturation stabilization on the in vitro and in vivo performance of self-emulsifying drug delivery systems.
The data suggest that digestion acts as a "trigger" for enhanced supersaturation and that solubilization/precipitation behavior is correlated with the degree of supersaturation on dispersion (S(M)DISP) or digestion (S (M)DIGEST). Expand
Toward the establishment of standardized in vitro tests for lipid-based formulations. 2. The effect of bile salt concentration and drug loading on the performance of type I, II, IIIA, IIIB, and IV
Across all formulations a remarkably consistent trend emerged such that the likelihood of precipitation was almost entirely dependent on the maximum supersaturation ratio (SR(M) attained on initiation of digestion, which may prove to be an effective tool in discriminating between LBFs based on performance. Expand
Toward the Establishment of Standardized In Vitro Tests for Lipid-Based Formulations, Part 3: Understanding Supersaturation Versus Precipitation Potential During the In Vitro Digestion of Type I, II,
The maximum supersaturation ratio (SRM) provides an indication of the supersaturation ‘pressure’ exerted by formulation digestion and is strongly predictive of the likelihood of drug precipitation in vitro and may also prove effective in discriminating the in vivo performance of LBFs. Expand
Lipid-Based Formulations and Drug Supersaturation: Harnessing the Unique Benefits of the Lipid Digestion/Absorption Pathway
Insight is offered into the unique manner by which lipid-based formulations (LBFs) may enhance the absorption of poorly water-soluble drugs via co-stimulation of solubilization and supersaturation through incorporation of LBF into lipid digestion and absorption pathways. Expand
In vitro digestion testing of lipid-based delivery systems: calcium ions combine with fatty acids liberated from triglyceride rich lipid solutions to form soaps and reduce the solubilization capacity
The use of high calcium concentrations does indeed force in vitro digestion of LCTs but may overestimate the extent of drug precipitation that occurs within the intestinal lumen, thereby reducing drug solubilization. Expand
'Stealth' lipid-based formulations: poly(ethylene glycol)-mediated digestion inhibition improves oral bioavailability of a model poorly water soluble drug.
The results of the current study indicate that self-assembled "stealth" LBFs have potential as a novel means of improving LBF performance and are suggested to mirror those of parenteral formulations. Expand
