• “All the easy drugs have been found now we have to go after the rocks”

• Majority of new development drugs have poor bioavailability.

• Solid Dispersion Improve bioavailability of insoluble drugs

• Formulators will add excipients to a formulation and spray drying will change the solid form of the substance IE making it more amorphous, and improve bioavailability.

• Make the API more amorphous add other substances Polymers IE HPMCAS, PVP, etc

• May increase Drug bioavailability 1000’s of times

• Solvent drying – Nitrogen inertion- closed cycle systems.

A biologic is manufactured in a living system such as a microorganism, or plant or animal cells. Most biologics are very large, complex molecules or mixtures of molecules. IE proteins.

These molecules are too large to pass through the walls of the digestive system.

They must be injected, inhaled, absorbed through the skin (patch), implanted devise.

Large Molecule Drugs Biologic

• Stabilization of protein by drying

Water removal

• Water is a good medium for degradation

Reactions

• Oxidation, surface adsorption

Denaturation aggregation

• In solid state Low molecular

Hydrolysis Minimized

• Storage stability better in solid state

Pyrogen a substance that causes fever.

When microbes die the cell wall are made up of Lipopolycaccharides when these enter the blood stream they cause fevers, endotoxins

Steam sterilization will not remove endotoxins

The endotoxins must be washed off the equipment
