Hydrophilic excipients like polyvinylpyrrolidone (PVP) are often used to improve the dissolution of poorly soluble drugs by increasing their wettability.
Enteric coatings protect the drug from being released in the acidic environment of the stomach and ensure it is released in the intestines where the pH is higher.
Matrix systems are a popular technique for sustained-release formulations, allowing the drug to be released slowly over time.
Nanoparticles enhance the bioavailability of drugs by improving solubility, targeting specific tissues, and enabling controlled release.
The thin-film hydration method is widely used to prepare liposomes, ensuring proper encapsulation of the drug within the lipid bilayer.
Surfactants reduce the surface tension between the drug particles and the liquid medium, improving dispersion and stability of the suspension.
