Equetro now available for treatment of manic and mixed episodes in bipolar disorder
BASINGSTOKE, UK and PHILADELPHIA, PA, 20 April 2005 -- Shire Pharmaceuticals Group announced that Equetro (carbamazepine extended-release capsules), the only carbamazepine formulation proven effective for patients with bipolar disorder, is now available in the United States.
"The availability of carbamazepine extended-release capsules is a significant milestone in bipolar disorder therapy," said Richard H. Weisler, M.D., Adjunct Professor of Psychiatry at University of North Carolina at Chapel Hill School of Medicine, Adjunct Assistant Professor of Psychiatry and Behavioral Sciences at Duke University Medical Center, and primary investigator of two carbamazepine extended-release capsule clinical trials. "A lot of patients have trouble responding to bipolar medications, so a new treatment option means we can reach more people who suffer from bipolar disorder and help them restore balance in their lives."
Bipolar disorder causes unusual changes in mood - including overly "high" and/or irritable symptoms ("manic episodes"), and symptoms of depression. Some patients experience both manic and depressed symptoms at the same time ("mixed episodes").
Equetro has received FDA approval for the treatment of acute manic and mixed episodes associated with Bipolar I Disorder. Equetro has been shown to significantly reduce manic symptoms in bipolar patients with manic and mixed episodes. In clinical trials,* patients treated with Equetro demonstrated a low incidence of clinically significant weight gain. The unique three-bead extended release delivery system of Equetro provides patients with smooth carbamazepine levels, and convenient administration. Patients take Equetro in twice-daily doses, which can be taken with or without food, and capsules may be opened and sprinkled onto soft food.
"Bipolar disorder is a serious and debilitating psychological disorder that not only seriously affects patients, but also their family members and friends," said Matthew Emmens, Chief Executive of Shire. "We are pleased to bring this new choice of treatment to patients and hope that Equetro will help them to restore balance in their lives and improve quality of life."
Bipolar disorder is one of the six leading mental disorders worldwide, according to the World Health Organization. More than two million American adults or about 1 percent of the population age 18 and older in any given year, are afflicted with bipolar disorder, also known as manic depression. The disorder is often not recognized as an illness, and as a result people may suffer for years before they are properly diagnosed and treated.
About bipolar disorder
Bipolar disorder is characterized by episodes of mania and depression, with periods of normal mood in between. The disorder can have devastating effects on an individual's life, although proper diagnosis and early treatment can usually alter the course of the illness.
Because of the severity of the illness, bipolar disorder is disruptive to patients, their families, friends and colleagues and can damage relationships, cause poor job or school performance and suicide. Although bipolar disorder is not curable, it is treatable and recovery is possible. Early diagnosis combined with drug therapy is key to optimal treatment.
Safety Information
Equetro contains carbamazepine. Please ensure patient is not taking any other form of carbamazepine.
The most frequently reported adverse events are dizziness, drowsiness, unsteadiness, nausea and vomiting. Initiating therapy at the lowest possible effective dose can minimize adverse events. Reports of transient or persistent decreased platelet or white blood cell count are not uncommon in association with the use of carbamazepine. Although the vast majority of cases of leukopenia have not progressed to the more serious conditions of aplastic anemia or agranulocytosis, complete pretreatment hematological testing should be obtained as a baseline. Patients should be monitored and discontinuation of the drug should be considered if any evidence of bone marrow depression occurs.
Because the possibility of a suicide attempt is inherent in bipolar disorder, close supervision of high-risk patients should accompany drug therapy.
Additional Information
Equetro was approved by the FDA on December 10, 2004 for the treatment of acute manic and mixed episodes associated with Bipolar I Disorder. It is available in 100 milligram (mg), 200 mg and 300 mg dosage strengths. Equetro has a formulation patent that runs until 2011 and will have three years market exclusivity under the U.S. Hatch-Waxman Act.
