Critical exploration of spray drying technology for new drug development

Spray drying
technology is a key technology widely used in the development of new drugs. It rapidly dries drug particles by injecting drug formulations in the form of tiny sprays into a hot air stream for rapid preparation and improved stability.

Four major advantages of spray drying in the preparation of new drugs:

·Spray drying technology

can be applied not only to the preparation of solid dispersions but also to the preparation of nanodispersions. In recent years, nanotechnology has been widely used in drug development. Since nanoparticles have a larger specific surface area and excellent bioavailability than conventional particles, better-targeted delivery and controlled release properties of drugs can be achieved. By controlling the particle size and solvent properties during the spraying process, spray drying technology can prepare nanoscale particles, which provide strong support for targeted delivery and controlled release of drugs.

• ·Maintaining drug stability is critical in the development of new drugs. Photosensitive and thermosensitive drugs are often susceptible to degradation and inactivation by light and heat. Spray drying technology can be utilized to prepare dry powder forms with no or low water content, thereby reducing exposure to water and improving stability. Additionally, the addition of a protective agent or coating treatment is one of the advantages of using this technology to further protect the active ingredient of the drug.

Spray drying technology is well known for its high preparation efficiency and scalability. The technology is easy to use with simple equipment processes and enables continuous production, which significantly improves preparation efficiency. In addition, spray drying technology is applicable to a wide range of pharmaceutical dosage forms, including solid particles, emulsions, suspensions, and films, making it widely scalable and adaptable.

As an important new drug development technology, spray drying technology not only improves the bioavailability and solubility of drugs but also protects the active ingredients and enhances stability. It provides strong support for new drug development and plays an important role in clinical applications.
