NASHVILLE, Tenn., Feb. 10, 2016 /PRNewswire/ -- Cumberland Pharmaceuticals Inc. (NASDAQ: CPIX) today announced the publication of an open label multicenter study adding to the growing body of literature that supports Vaprisol^® (conivaptan) Injection. The study evaluated both 20 and 40 mg/day doses of conivaptan in hyponatremic patients. The new publication is currently available as open access articles in the journal Drug Design, Development and Therapy.

Hyponatremia is an electrolyte disturbance in which sodium ion concentration in blood plasma is lower than normal.  This can be associated with a variety of critical care conditions including congestive heart failure, liver failure, kidney failure and pneumonia. This study was conducted at 26 U.S. and 2 international centers. A total of 251 patients were enrolled in the study.

Both doses of conivaptan were efficacious in increasing the patients' sodium concentrations over 4 days of treatment with no observed increase in the frequency of adverse events using the higher dose. The majority of patients obtained a clinically significant increase in their sodium concentration by 24 hours after initiation of conivaptan therapy. Patients receiving the higher dose had a faster rate of increase, absolute increase and longer duration of effect. The pharmacokinetic parameters of both doses were similar to what has been reported previously, exhibiting greater-than-dose-proportional plasma concentrations.
