Muscle Cramps and Spasms: Drug Therapy

Therapy goal for muscle spasms

Prophylaxis of muscle spasms.

Therapy recommendations

Therapy goal for spasticity

  • Functional improvement
  • Pain relief

Therapy recommendations

  • Baclofen, tizanidine (mystification/antispasticity), first-line agents.
  • Small studies showed a positive effect for progabide, L-dopa, clonidine* as well as cannabis (spasticity in multiple sclerosis),). The indication is usually given when there is pronounced spasticity* * and only slight impairment of voluntary motor function.
  • Pronounced functional effects are not achievable with all known agents to date.
  • Botulinum toxin (indications see below).

* Side effects Cinchonism: thrombocytopenia (decrease in platelets/platelets), DIC (disseminated intravascular coagulopathy), HUS (hemolytic uremic syndrome), hypersensitivity reactions, tinnitus, dizziness, gastrointestinal (nausea, vomiting, diarrhea/diarrhea); very rare (with long-term prescription): Fatal ventricular arrhythmias due to delay of repolarization in the conduction system of the myocardium, detectable by prolongation of the QT interval on ECG: mortality risk in patients < 50 years. : adjusted hazard ratio of 3.06 (2.51-3.73).

* * Tolperisone (muscle relaxants) is approved only for the treatment of poststroke spasticity in adults. Outside of this approved indication, for example, there is a risk for hypersensitivity reactions (up to and including anaphylactic shock) without proven benefit.

Indications for botulinum toxin (according to national and European consensus groups).

  • Early rehabilitation for spast. Flexion tone of the arms
  • Severe adductor spasticity
  • Spasticity in children with kindl. Cerebral palsy → improvement of walking, standing and function of the hands.
  • Spastic pointed foot/inversion, not remediable by splints, physical therapy as well as oral medication.

Other indications for botulinum toxin.

  • Blepharospasm (eyelid spasm).
  • Wrinkle correction
  • Focal hyperhidrosis – excessive sweating on certain parts of the body.
  • Spasm hemifacialis – spasm of the part of the facial muscles supplied by the facial nerve.
  • Therapy-resistant spastic urinary bladder dysfunction.
  • Cervical dystonia (torticollis)

Supplements (dietary supplements; vital substances)

Suitable dietary supplements should contain the following vital substances:
