- Delamanide is known to have an excellent bactericidal action against tuberculosis bacteria, multidrug-resistant tuberculosis bacteria, and atypical mycobacteria (for example, Patent Documents 1 to 3).
- the currently marketed delamanide formulation improves the solubility of delamanide and improves drug absorption by dissolving delamanide in an organic solvent together with a polymer and then spray drying.
- this method requires a large cost for the treatment of the organic solvent and requires solvent recovery, which causes problems such as environmental burden.
- the inventors of the present invention have studied a method for micronizing delamanide by a method that is as cheap as possible and has a low environmental load.
- submicron particles easily aggregate due to cohesive force (eg intermolecular force, capillary force, electrostatic force, etc.) that acts after pulverization, and generate secondary particles. It was not easy to prevent agglomeration.
- delamanide is extremely hydrophobic, it was difficult to grind in water.
- the present inventors have found that by mixing delamanide and a specific surface stabilizer and performing wet pulverization, it is possible to efficiently pulverize to submicron particles and to suppress secondary particle generation, and further improvements are made.
