Effective at preventing or relieving muscle spasms and involuntary muscle contractions.
From anti- (against) + spasmodic (from Greek spasmos, a spasm or convulsion, from span, to pull). The term developed in medicine and pharmacology as treatments were discovered for conditions causing painful muscle contractions.
Antispasmodic drugs like those used for irritable bowel syndrome affect nerves controlling muscles—it's fascinating how the same type of medication can treat both muscle cramps and digestive issues by targeting the nervous system's muscle-controlling signals.
