Patent number: 5595987Abstract: The present invention relates to a method of using zatebradine by intravenous (IV) injection to retard or eliminate arrhythmias due to abnormal spontaneous activity in subendocardial Purkinje fibers. More specifically, the present invention relates to the use of zatebradine to reduce intracellular Na.sup.+ activity in Purkinje fibers and block I.sub.f current. Arrhythmias due to abnormal spontaneous activity in subendocardial Purkinje fibers occur 24 hours after occlusion of the left anterior descending (LAD) coronary artery in canine heart. These Purkinje fibers in the infarcted hearts are depolarized and have elevated intracellular Na.sup.+ activity. The major current underlying normal automaticity in these fibers is the I.sub.f current. Zatebradine reduces intracellular Na.sup.+ activity in Purkinje fibers by 4 mM. In vivo, 0.25-1.0 mg/kg intravenous injections of zatebradine slow ventricular rhythms by 24%. Although zatebradine also slows sinus nodal rate, it precipitates a more severe arrhythmia.Type: GrantFiled: July 22, 1994Date of Patent: January 21, 1997Assignee: The Trustees of Columbia University in the City of New YorkInventors: Steven Lasker, Richard Klein

Patent number: 5252337Abstract: A controlled release formulation of a calcium channel blocker for oral administration contains non-pareil seeds loaded with a calcium channel blocker, particularly diltiazem, nifedipine, or verapamil, and then microencapsulated in ethylcellulose by phase separation techniques. The resultant microcapsules provide an approximately zero order release rate, preferably over 12 to 16 hours. These microcapsules may be filled into gelatin capsules.Type: GrantFiled: June 25, 1991Date of Patent: October 12, 1993Assignee: Eurand America, Inc.Inventor: Thomas C. Powell

Patent number: 5219621Abstract: A diltiazem pellet formulation for oral administration comprises a core of diltiazem or a pharmaceutically acceptable salt thereof in association with an organic acid, and a multi-layer membrane surrounding the core and containing a major proportion of a pharmaceutically acceptable film-forming, water insoluble synthetic polymer and a minor proportion of a pharmaceutically acceptable film-forming, water soluble synthetic polymer. The number of layers in the membrane and the ratio of the water soluble to water insoluble polymer being effective to permit release of diltiazem from the pellet at a rate allowing controlled absorption thereof over a twelve hour period following oral administration. The pellet has a dissolution rate in vitro which when measured in a dissolution apparatus (Paddle) according to U.S. Pharmacopoeia XXI in 0.05 M KCl at pH 7.0 results in not more than 35% of the total diltiazem being released after 2 hours of measurement.Type: GrantFiled: July 22, 1992Date of Patent: June 15, 1993Assignee: Elan Corporation, PlcInventors: Edward J. Geoghegan, Seamus Mulligan, Donald E. Panoz
