  • Nateglinide is a low water-soluble active agent. Therefore the dispersion of the formulations comprising this active agent in the body takes a long time.
  • nateglinide should act within a short time after intake in order to quickly decrease blood sugar level which particularly increases after meals. Thus the formulations comprising nateglinide should disperse within a short time.
  • nateglinide is structurally an amino acid derivative. This kind of molecules may cause various degradation products by reacting with some excipients or solvents used basically in pharmaceutical technology. As a result, the amount of active agent in the formulation decreases and thus the efficiency of treatment is affected negatively.

Surprisingly, the inventors have observed that when the mixture comprising nateglinide and at least one pharmaceutically acceptable excipient is granulated with a granulation solution comprising a binder agent in the range of 1-5% by weight, the nateglinide formulations obtained disperse within a short time, for example in less than 10 minutes, and no degradation product occurs.
