Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dantrolene inhibits calcium release from the sarcoplasmic reticulum by binding to the ryanodine receptor (RyR1), thereby reducing intracellular calcium concentration and decreasing muscle contraction.
Caffeine is a central nervous system stimulant that acts as an antagonist at adenosine receptors (A1 and A2A subtypes), thereby reducing the inhibitory effects of adenosine. Dihydroergotamine is an ergot alkaloid with partial agonist activity at serotonin 5-HT1B/1D receptors, leading to vasoconstriction of cranial blood vessels. Thioridazine is a typical antipsychotic with high affinity for dopamine D2 receptors and moderate affinity for serotonin 5-HT2A, alpha1-adrenergic, and histamine H1 receptors.
Initially 25 mg orally once daily for 7 days, then 25 mg three times daily for 7 days, then 50 mg three times daily for 7 days, then 100 mg three times daily; maximum 400 mg/day in divided doses. For malignant hyperthermia crisis: IV bolus 1 mg/kg, repeated as needed up to 10 mg/kg cumulative dose.
Chlorzoxazone 500 mg to 750 mg orally three to four times daily.

Terminal elimination half-life: 8.7-14.4 hours in adults; longer with hepatic dysfunction.
10-12 hours in healthy adults; prolonged to 18-24 hours in hepatic impairment or elderly
Renal: ~65% as unchanged drug; biliary/fecal: ~15% as metabolites; remainder metabolized and eliminated via urine.
Renal excretion of unchanged drug (70-90%) and glucuronide conjugates; biliary/fecal elimination accounts for <10%
