Ulixacaltamide’s Path to Standard-of-Care Status in Essential Tremor: Clinical Precision and Commercial Realities

T-type calcium channel inhibition decouples tremor reduction from systemic toxicity. See Disclaimer below * The current pharmacopoeia for Essential Tremor (ET) relies heavily on systemic blunting agents—beta-blockers and barbiturates—that reduce tremor amplitude at the cost of significant physiological depression. Ulixacaltamide (PRAX-944) represents a fundamental divergence from this paradigm. By
