Abstract:
Fluoroquinolones has been rarely associated with exacerbation of myasthenia gravis (MG). We present a case of MG following a treatment with prulifloxacin, a new broad-spectrum oral fluoroquinolone. Fluoroquinolones of any generation may interfere with neuromuscular transmission and should be avoided in patients with MG.
Insights
Fluoroquinolones, including prulifloxacin, can rarely worsen myasthenia gravis (MG). Patients with myasthenia gravis should avoid fluoroquinolone antibiotics due to potential neuromuscular transmission interference.
Area of Science:
- Neurology
- Pharmacology
Background:
- Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disease.
- Fluoroquinolones are broad-spectrum antibiotics with known potential side effects.
Observation:
- A rare case of myasthenia gravis exacerbation occurred after treatment with prulifloxacin, a novel oral fluoroquinolone.
- This highlights a potential adverse drug reaction within the fluoroquinolone class.
Findings:
- Fluoroquinolones, regardless of generation, may disrupt normal neuromuscular transmission.
- Prulifloxacin use was temporally associated with a significant worsening of MG symptoms in this patient.
Implications:
- Clinicians should exercise caution when prescribing fluoroquinolones to patients diagnosed with myasthenia gravis.
- Avoiding fluoroquinolones in MG patients is recommended to prevent potential exacerbations and preserve neuromuscular function.

01:20Myasthenia Gravis: Overview and Treatment
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...

01:15Myasthenia Gravis: Diagnostic Tests
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
01:26Chemical Synapses
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

01:28Disorders of the Skeletal Muscle
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
