Lipophilic drug compounds often exhibit poor aqueous solubility, hindering absorption and increasing drug development costs. This review revisits solubility concepts to guide the selection of effective pre-formulation and formulation strategies for improved drug delivery.
Area of Science:
- Pharmaceutical Sciences
- Drug Delivery
- Physical Chemistry
Background:
- High-throughput screening frequently identifies lead compounds with high molecular weight and poor aqueous solubility.
- Poor aqueous solubility of lipophilic compounds impedes dissolution, absorption, and increases drug development costs.
- Existing pre-formulation and formulation strategies struggle to consistently overcome solubility challenges.
Purpose of the Study:
- To revisit theoretical and mathematical concepts of solubility and dissolution.
- To provide guidance on selecting appropriate pre-formulation and formulation strategies.
- To review recent research in solubility enhancement over the past decade.
Main Methods:
- Review of fundamental principles of solubility and dissolution.
- Analysis of strategies for manipulating crystal lattice properties and activity coefficients.
- Literature survey of research on solubility enhancement techniques.
Main Results:
- A deeper conceptual understanding of solubility is crucial for effective strategy selection.
- Theoretical frameworks can guide rational decisions in pre-formulation and formulation.
- The review synthesizes current knowledge and highlights research trends in the field.
Conclusions:
- Addressing poor aqueous solubility requires a strong theoretical foundation.
- Rational selection of strategies based on solubility principles can optimize drug development.
- Continued research is essential to overcome persistent solubility challenges in drug discovery.

Theories of Dissolution: Diffusion Layer Model
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...
