ANSWER: b) Inderal
DESCRIPTION
Myasthenia Gravis is muscle weakness with fatigue which may
ultimately leads to the paralysis of the associated muscle. It is characterized
by the lack of binding of acetylcholine to the postsynaptic receptors of the
neuromuscular junction. The most common sign is the drooping of the eyelid that
is ptosis. Inderal contains propranolol which is a non-selective β-blocker; it
must be taken in caution with patients having Myasthenia Gravis. The use of the
drug for the short term is not proved to be risky however chronic long-term use
of the drug needs monitoring. Even calcium channel blockers must be used with
caution in Myasthenia Gravis.
