Nanosuspensions: These are colloidal dispersions of drug nanoparticles stabilized by surfactants. They enhance solubility by providing a large surface area for dissolution. Lipid-based Nanocarriers: These include liposomes, solid lipid nanoparticles, and nanostructured lipid carriers that encapsulate poorly soluble drugs, enhancing their solubility and bioavailability. Polymeric Nanoparticles: Drugs are encapsulated within or attached to polymers, which can enhance solubility and provide controlled release. Cyclodextrin Complexes: Cyclodextrins are cyclic oligosaccharides that can form inclusion complexes with drugs, increasing their solubility and stability.
