Zusammenfassung
Hintergrund
Muskelkrämpfe sind plötzlich auftretende, unwillkürliche, meist schmerzhafte Kontraktionen eines Muskels, selten einer Muskelgruppe. Sie können idiopathisch oder im Rahmen unterschiedlicher neuromuskulärer Erkrankungen vorkommen und teilweise aufgrund ihrer Frequenz und Dauer die Lebensqualität erheblich beeinträchtigen. Zur Behandlung gibt es bislang nur wenige gut wirksame Medikamente.
Ergebnisse
In dieser Fallserie berichten wir von 5 Patienten mit Muskelkrämpfen unterschiedlicher Genese, die gut auf die Behandlung mit Brivaracetam ansprachen.
Diskussion
Brivaracetam wird eigentlich zur Behandlung epileptischer Anfälle eingesetzt. Es bindet an das synaptische Vesikelprotein 2A (SV2A), welches auch an Nerven- und Nervenwurzeln vorkommt. SV2A reguliert die exozytotische Freisetzung von Neurotransmittern, was die Wirkung von Brivaracetam auf Muskelkrämpfe erklären könnte.
Schlussfolgerung
Es sind weitere Studien erforderlich, um die Wirkung von Brivaracetam auf Muskelkrämpfe nachzuweisen.
Abstract
Background
Muscle cramps are suddenly occurring involuntary, mostly painful contractions of a single muscle, rarely of a muscle group. They can be idiopathic or occur in various neuromuscular diseases and can sometimes substantially impair the quality of life due to the frequency and strength. Only a few drugs are available for the effective treatment of cramps.
Results
In this case series we report on five patients with cramps of different origin who responded well to treatment with brivaracetam.
Discussion
Brivaracetam is actually used for the treatment of epileptic seizures. It binds to the synaptic vesicle protein 2A (SV2A), which also occurs in nerves and nerve roots. The SV2A regulates the exocytotic release of neurotransmitters, which could explain the effect of brivaracetam on muscle cramps.
Conclusion
Further studies are needed to demonstrate the effect of brivaracetam on muscle cramps.
