The presence of the superfamily members of the ATP binding cassette (ABC) transporters is well established as the main cause of multidrug resistance, since they efflux therapeutic compounds from cells and reduce the intracellular drug levels.
The publication, entitled Daily Intraperitoneal Administration of RGZ Does Not Improve Lung Function or Alveolarization in Preterm Rabbits Exposed to Hyperoxia, was aimed at testing the efficacy of three types of Thiazolidenoides (TZN) in preterm rabbits with bronchopulmonary dysplasia.
Last month, the ICH launched a draft on Drug Interaction Studies regulatory. The guideline includes the regulations of the European, American and Japanese medical agencies and covers both in vitro and clinical studies.
It is well known that food intake changes luminal conditions (e.g. pH, motility, microbiota,…) in the stomach and the small intestine, modifying drugs bioavailability. Food-drug interactions are one of the major challenges for oral-administered drugs, even more so if considering the growing use of food supplements and functional foods.
The endothelial cells that conform the BBB limit the passage of blood circulating endogenous substrates and larger molecules to the brain. This intrinsic protective role is also a major hurdle for reasearchers developing drugs for Central Nervous System (CNS) disorders.
