Definition His bundle electrography is a test that measures electrical activity in a part of the heart that carries the signals that control the time between heartbeats (contractions). Alternative Names His bundle electrogram; HBE; His bundle recording; Electrogram - His bundle How the test is performed The bundle of His is a group of fibers that carry electrical impulses through the center of the heart. If these signals are blocked, you will have problems with your heartbeat. The His bundle electrography is part of an electrophysiology (EP) study. You are given a mild sedative before the test. An intravenous catheter (IV line) is inserted into your arm so that you can be given medicines during the test. Electrocardiogram (ECG) leads are placed on your arms and legs. Your arm, neck, or groin will be cleaned and numbed with a local anesthetic. After the area is numb, the cardiologist makes a small cut in a vein and inserts a thin tube called a catheter inside. The catheter is carefully moved t...
Two weeks ago I told you that the FDA approved a generic version of Lyrica ® (pregabalin) made by Lupin Limited, but I wasn't able to find out when it might actually be available on the market. Now I know why I couldn't find that information. Apparently Lupin was awaiting a court decision as to whether or not on Pfizer Inc.'s patents for Lyrica were valid.
That decision came down last Thursday, July 19, 2012. Judge Gregory M. Sleet of the U.S. District Court of Delaware upheld the validity of Pfizer's patents for Lyrica, giving them exclusive rights to the medication until December 30, 2018. In addition, Judge Sleet ordered the FDA to stop approving generic forms of pregabalin until Pfizer's patents expire.
The Story Behind the Decision
In 2009, Pfizer filed a lawsuit charging patent infringement against Israel's Teva Pharmaceutical Industries, India's Sun Pharmaceutical Industries, and U.S. firms Mylan and Watson Pharmaceuticals, who all sought FDA approval ...
There is a lot of talk about research and medical advances
in the treatment of multiple sclerosis , but I would like to return to the fundamentals of MS
care and how these new treatment options fall into the framework of MS care.
There are three important arms of MS treatment:
Modifying Agents - Medications that are used to change the course of MS, but
which you may not feel any current effect from (though you may have side
effects unfortunately), but are like an insurance policy for the future. There
are 5 FDA approved medications for Relapsing forms of MS: Avonex ®, Rebif ®,
Betaseron ®, Copaxone ® and Tysabri ®. Novantrone® is a chemotherapy drug, also FDA
approved for worsening relapsing MS or secondary progressive MS.
Most of the research you read about
is aimed at disease modification: the oral medications (Cladribine, Fingolimod,
Teriflunomide, BG00012, Laquinomod, etc.); the newer injectables (Atacicept
etc.); the IV infusions ...
