Pharmaceutical combination composition comprising complex formulations of Ivacaftor and Lumacaftor and their salts and derivatives, process for their preparation thereof and pharmaceutical compositions containing them

摘要

Pharmaceutical combinations comprise stable complexes with controlled particle size, increased apparent solubility and increased dissolution rate comprising as active compound Ivacaftor and Lumacaftor, their salts, or derivatives thereof, which are useful in the treatment of cystic fibrosis transmembrane conductance regulator (CFTR) mediated disease. More specifically, the pharmaceutical composition comprising the complexes possesses instantaneous redispersibility, increased apparent solubility and permeability, no observable food effect which deliver the opportunity of precise dosing and ease of administration of the reconstituted complex in solution form. Further disclosed are methods of formulating and manufacturing the complexes, pharmaceutical compositions containing the complexes, and methods of treatment using the complexes and their pharmaceutical compositions.
