Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Centrally acting muscle relaxant; inhibits polysynaptic reflexes at the spinal cord level, possibly by depressing the central nervous system.
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.
250-500 mg orally once daily, may increase to 500 mg twice daily if needed. Maximum 500 mg/day.
Chlorzoxazone 500 mg to 750 mg orally three to four times daily.

Terminal elimination half-life is approximately 2–3 hours, allowing for multiple daily dosing.
10-12 hours in healthy adults; prolonged to 18-24 hours in hepatic impairment or elderly
Renal excretion of unchanged drug and metabolites accounts for approximately 50% of an oral dose; fecal excretion accounts for about 20%.
Renal excretion of unchanged drug (70-90%) and glucuronide conjugates; biliary/fecal elimination accounts for <10%
