News Release

NASHVILLE, Tenn., April 7, 2020 /PRNewswire/ -- Cumberland Pharmaceuticals Inc. (NASDAQ: CPIX) a specialty pharmaceutical company, today announced an initiative to increase availability of Vaprisol^® (conivaptan hydrochloride) injection for treating hyponatremia, associated with critical care patients during the COVID-19 pandemic. Vaprisol is an FDA approved treatment for hyponatremia, a potentially life-threatening condition that can often afflict patients in the Intensive Care Unit ("ICU").

Cumberland's initiative includes special supply and financial arrangements, including favorable pricing and payment terms, for hospitals and clinics to help ensure timely access to Vaprisol during this healthcare crisis. For more information regarding this special access, contact Jim Herman, Cumberland's Senior Vice President National Accounts at jherman@cumberlandpharma.com.

"It is our hope that this enhanced access to Vaprisol will help lead to shorter ICU stays and thereby free-up potentially life-saving ICU beds that could become in short supply during the COVID-19 pandemic," said A.J. Kazimi, Chief Executive Officer of Cumberland Pharmaceuticals Inc.

Hyponatremia frequently occurs when the concentration of sodium in a patient's blood is abnormally low, which can lead to neurologic dysfunction, decreased mental function and cerebral edema, among other complications. The condition is particularly prevalent among ICU patients. On average, over 30 percent of patients admitted to an ICU have hyponatremia¹ and another 18 percent develop the condition during their ICU stay². Several studies have shown that patients with hyponatremia spend a longer time in the ICU, spend more time on mechanical ventilators and have increased mortality while in the ICU³. Vaprisol can help address hyponatremia in the first 24 hours⁴.

About Vaprisol^®

Vaprisol is an intravenous treatment for hyponatremia used in the critical care setting. 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. Vaprisol is a vasopressin receptor antagonist that raises serum sodium levels and promotes free water secretion. Vaprisol was approved by the U.S. Food and Drug Administration in 2005 for euvolemic hyponatremia and in 2007 for hypervolemic hyponatremia. For full prescribing information visit www.vaprisol.com.
