It was announced today that OraPharma, Inc. has been acquired by Water Street Healthcare Partners. They are a private equity firm that focuses on health care. OraPharma's flagship product is Arestin, a locally delivered antibiotic used in periodontal therapy. If you haven't tried this for your patients, its time to do your homework. The thing I have always liked about OraPharma is the amount of research they have done to prove up their claims. We have all seen different attempts at delivering antiobiotics to help reduce periodontal pockets, but this one really sticks (no pun intended). It will be interesting to see what direction Water Street Healthcare takes with the strong foundation they already have.
