The drug chymocycline contained an antibiotic, tetracycline, and an anti-inflammatory agent in the form of proteolytic enzymes of pancreatic origin (trypsin, chymotrypsin (pancreatin or lipase)), hence the name combining “chymo” and “cycline”. The drug was used to treat many types of infections, in odonto-stomatology, obstetric, and gynecology. The drug was made from a two-piece gelatin capsule allowing the delayed-release of the proteolytic pancreas enzyme and the antibiotic. The drug is no longer used today but tetracycline remains a major antibiotic immensely used. It is currently one of the most consumed antibiotics for human therapy, veterinary purpose, and agricultural activities.

The advertising highlighted the capacity of chymocycline to penetrate tissues. A simple pictural view of the drug capacity to cross physiological barriers, such as membranes and epithelial tissues.
