EISAI TO LAUNCH NEW FINE GRANULE FORMULATION OF TACHYARRHYTHMIA TREATMENT TAMBOCOR® SUITABLE FOR PEDIATRIC PATIENTS IN JAPAN
Tambocor® Fine Granules 10%, a new formulation of anti-arrhythmic agent Tambocor (flecainide acetate), on June 29 in Japan. Eisai received marketing and manufacturing approval for this formulation on February 16, 2015, and the product was added to Japan's National Health Insurance drug price list on June 19 of the same year.
This product is a fine granule formulation that can be adjusted to account for age and body surface area for administration to pediatric patients, and can be administered to patients who have difficulty taking tablets. In addition, Eisai has made special efforts, such as reducing the bitterness, to make Tambocor Fine Granules easy to administer.
Tambocor suppresses tachyarrythmia by blocking cardiac sodium channels and slowing down cardiac conduction. Approved and launched as Tambocor Tablets in Japan in 1991, the drug was originally indicated for the treatment of tachyarrythmia in adults, and was approved for the treatment of tachyarrythmia (paroxysmal atrial fibrillation/flutter, paroxysmal superventricular, ventricular) in pediatric patients in May 2010. Furthermore, Tambocor is the only sodium channel blocking agent in Japan to be approved for the treatment of tachyarrythmia in pediatric patients.
Pediatric arrhythmia not only causes heart palpitations, dizziness, shortness of breath and other symptoms that impact the daily lives of patients, it is also said to be one of the most common causes of sudden death among children. Regarding pediatric arrhythmia, Eisai has received approval of additional indications for pediatric patients for Tambocor Tablets in May 2010, and for the calcium channel blocker Vasolan® Tablets 40 mg and Vasolan for intravenous injection 5 mg in May 2011. By providing the easy to measure and administer Tambocor Fine Granules 10% in addition to Tambocor Tablets, Eisai will continue to make further contributions to address their needs of patients with tachyarrhythmia.
