Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin01:26

Directly Acting Muscle Relaxants: Dantrolene and Botulinum Toxin

723
Directly acting muscle relaxants like dantrolene and botulinum toxin (BoNT) have distinct mechanisms and applications. Dantrolene, a hydantoin derivative, acts on the ryanodine receptor (RYR1) in skeletal muscle cells. RYR1 are calcium channels present at the sarcoplasmic reticulum membrane. In response to excitation, they release calcium ions from the sarcoplasmic reticulum to the cytosol. Calcium promotes actin-myosin-mediated contraction of muscles.
The binding of dantrolene to the RYR1...

Skeletal Muscle Relaxants: Therapeutic Uses

540
Skeletal muscle relaxants are used to relax muscle tone and alleviate painful muscle contractions. However, the choice of skeletal muscle relaxants depends on the duration of the surgical procedure in order to minimize potential side effects. Skeletal muscle relaxants like neuromuscular blocking agents [NMBAs] are commonly employed as adjuvants alongside general anesthetics in clinical settings. NMBAs are also used to maintain controlled ventilation during surgery of the larynx or pharynx...

Depolarizing Blockers: Mechanism of Action01:28

Depolarizing Blockers: Mechanism of Action

1.7K
Depolarizing blockers act on skeletal muscle fibers' membranes and induce their depolarization. Most depolarizing blockers have two quaternary N+ atoms that bind the nicotinic acetylcholine receptors and cause neuromuscular blockade within minutes.
Succinylcholine is the most commonly used depolarizing blocker. Chemically, it constitutes two molecules of acetylcholine joined together by an acetate methyl group. They act on the receptors in the same way as acetylcholine. Because...

Classification of Skeletal Muscle Relaxants

2.6K
Skeletal muscle relaxants are a group of drugs that can reduce muscle stiffness and induce temporary paralysis to relieve pain. These agents can act centrally to reduce muscle tone or spasms in painful conditions such as multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or spinal injuries; they are called antispasmodics or spasmolytics.
Peripherally acting skeletal muscle relaxants interfere with the neurotransmission at the neuromuscular end plate to induce paralysis during...

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action01:17

Nondepolarizing (Competitive) Neuromuscular Blockers: Mechanism of Action

2.0K
Nondepolarizing neuromuscular blockers induce paralysis by competitively blocking nicotinic acetylcholine receptors at the muscle end plate. Examples include pancuronium, mivacurium, vecuronium, and rocuronium. These quaternary ammonium derivatives are administered intravenously, are poorly absorbed, and are excreted via the kidneys.
Competitive antagonists prevent acetylcholine from binding to its receptor, inhibiting membrane depolarization. Without conformational changes or intrinsic...

Nondepolarizing (Competitive) Neuromuscular Blockers: Pharmacological Actions

490
Nondepolarizing neuromuscular blockers prevent the membrane depolarization of muscle cells and inhibit muscle contraction. These are usually administered with anesthetics to achieve complete muscle relaxation. Upon administration, these drugs first block the small, rapidly contracting muscles of the face and hands, followed by the larger muscles of the trunk and the intercostal muscles. The diaphragm is the last muscle to be affected.
Although all competitive neuromuscular blockers are designed...

Area of Science:

  • Neurology
  • Neurosurgery
  • Movement Disorders

Background:

  • Cervical dystonia, also known as spasmodic torticollis, involves involuntary neck muscle contractions causing abnormal head posture.
  • Medical management often fails for severe cases, necessitating surgical intervention.

Purpose of the Study:

  • To present a case study of surgical treatment for severe cervical dystonia.
  • To demonstrate the technique of selective denervation using a modified Bertrand procedure.

Main Methods:

  • A 41-year-old male patient with severe right rotational torticollis underwent surgical treatment after failed medical management.
  • The surgical procedure involved selective denervation via a modified Bertrand approach, detailing anatomical landmarks and surgical planes.

Main Results:

  • The patient experienced significant improvement in head posture, with the head remaining straight post-surgery.
  • No residual pain was reported at the 1.5-year follow-up.

Conclusions:

  • Selective denervation using a modified Bertrand procedure is an effective surgical treatment for severe cervical dystonia.
  • This surgical approach can lead to sustained correction of head posture and pain relief in patients with spasmodic torticollis.
