FPM in Inhaler and Nasal Spray

Foreign Particle Matter control plays a particularly significant role in inhalable drug quality control. rap.ID and the users of Single Particle Explorer technology can look back on 15 years of experience in the IPAC-RS best-practice approach for the control and enumeration of foreign particulate matter in MDI, DPI and nasal spray formulations.

FPM in Inhaler and Nasal Spray 15 years of experience in Foreign particle studies in the Dry Powder Inhaler formulation

Fast and efficient Foreign Particulate Matter studies

rap.ID provides thorough Foreign Particulate Matter identification, method development and validation in MDI and DPI, as well as Nasal Spray formulations, within an extremely short timeline.  This allows you to streamline your new drug application, with regards of  FPM assessment  using rap.ID´s services. You can rely on experience based on more than 15 successfully approved New Drug Applications

from rap.ID data. rap.ID´s experience ranges from method development and validation for the enumeration, to the identification of foreign particulate matter. It starts with a free of charge proposal on a FPM study following the ICH guidelines and industries best practice.

Whilst maintaining a close discussion with the client, rap.ID develops a method to control the level of FPM in your product. With this method preliminary validations are used, ensuring that all the parameters are determined such as: linearity, accuracy, precision, repeatability and intermediate precision of the method.

Succsessfull investigations and validations
