Conventional Surfactants and a Model Based on Molecular Descriptors as Alternatives to the Drug Solubility in Fasted State Simulated Intestinal Fluid
Biorelevant media, such as fasted state simulated intestinal fluid (FaSSIF), are often used to forecast in vivo behavior of oral solid formulations in the gastrointestinal tract. This study uses conventional surfactants (Tween 80 and sodium lauryl sulfate) and a model based on structural parameters (i.e., molecular descriptors) to evaluate possible alternatives to FaSSIF for solubility evaluation of three poorly soluble drugs. The solubility of enrofloxacin, lamotrigine, and phenobarbital was determined in phosphate buffer solution (PBS, pH 6.5) and FaSSIF. The molecular descriptors of drugs were computed, and a mathematical model based on logistic regression was generated to estimate solubilization in FaSSIF compared with PBS. The results demonstrated that solubility of enrofloxacin, lamotrigine, and phenobarbital in Tween 80 (0.1% w/v) was similar to their solubility in FaSSIF, and the proposed model calculated the solubilization ratio with 80% accuracy. In conclusion, Tween 80 in low concentration (i.e., 0.05%) is an appropriate low-cost alternative to FaSSIF, and the proposed model can be used to evaluate the possibility of solubilization in FaSSIF.
期刊介绍:
Dissolution Technologies is a peer reviewed quarterly
publication reporting ongoing, useful information on
dissolution testing of pharmaceuticals. It provides an
international forum for dissolution analysts to receive
and exchange information on various dissolution topics.
Dissolution Technologies welcomes submissions related
to dissolution, in vitro release, and disintegration testing.
These topics should be the major focus of the article.
Do not submit articles where the focus is formulation
development with dissolution testing as one of many
tests.
