WHAT FIRDAPSE IS AND WHAT IS IT USED FOR
FIRDAPSE is used to treat symptoms of a disease of the nerves and the
muscles called Lambert-Eaton
myasthenic syndrome or LEMS in adults. This disease is a disorder
affecting the transmission of nerve
impulses to muscles, resulting in muscle weakness. It can be
associated with certain tumour types
(paraneoplastic form of LEMS) or in the absence of these tumours
(non-paraneoplastic form of
LEMS).
In patients suffering from this disease, a chemical substance called
acetylcholine, which communicates
nerve impulses to muscles is not released normally and the muscle
doesn't receive some or all of the
nerve's signals.
FIRDAPSE works by increasing the release of acetylcholine and helps
the muscle to receive the nerve
signals.
