Mednax, a Fort Lauderdale health care company, said Tuesday that it increased the borrowing capacity of its revolving credit facility to $800 million.

Mednax operates physician practice groups specializing in anesthesia and pediatric specialties.

Its previous credit facility was for $500 million. The company said it will use the expanded credit facility, along with cash flow, to fund anesthesia acquisitions and for other corporate purposes.

The company also extended the maturity date of the credit facility through 2017 and maintained interest rates similar to those under the prior facility.

The new facility was provided by a syndicate of 14 financial institutions.
