Neuromuscular transmission may be negatively influenced by many drugs and agents. Some of them are targeted to this purpose
– most important are the following: depolarizing and non-depolarizing neuromuscular blocking agents (used to produce muscular
paralysis in anesthetized patients), botulinum toxin (effectively weakening appropriate muscles for treatment of spasticity and
dystonic syndromes) and cholinesterase inhibitors (used to reduce clinical symptoms in myasthenia gravis). Furthermore, several
drugs may negatively influence the neuromuscular transmission as an undesirable side effect, particularly in case of pre-existed
impaired function of neuromuscular junction (mainly in patients with myasthenia gravis). Among others, D-penicillamine, interferon
alfa, magnesium, some antibiotics, quinidine, procainamide, statins, and calcium channel blockers may present with such
an influence. Furthermore, transient worsening of myasthenia gravis may be evoked by corticosteroids.
