Telemetric

Capsules

The application of telemetric capsules offers various opportunities in oral biopharmaceutics.  Due to the recent progress in developing supporting techno-logies and the improved accessibility of certified commercial products, the interest into this in vivo technique has increased in the last years . We are using wireless motility capsules to characterize the transit conditions of oral dosage forms in the GI tract of humans and animals. By this, we are able to determine luminal pH, temperature and pressure values in high temporal resolution. These data form the basis of our biorelevant in vitro tools.
