Enerisant
chemical compound
Enerisant (INNTooltip International Nonproprietary Name; developmental code name TS-091) is an experimental drug under investigation as a potential treatment for narcolepsy. It is a member of the histamine H3 receptor antagonist/inverse agonist class of medications.
Pharmacology
Pharmacodynamics
Enerisant functions as a potent and highly selective antagonist/inverse agonist of the histamine H3 receptor. This mechanism of action is similar to that of pitolisant, a currently approved H3 receptor antagonist/inverse agonist for narcolepsy; however, enerisant has demonstrated greater affinity and selectivity for the H3 receptor in preclinical studies. By blocking H3 receptors, enerisant increases histamine release from histaminergic neurons, leading to stimulation of postsynaptic histamine H1 receptors, a key mechanism in promoting wakefulness
Pharmacokinetics
Enerisant exhibits minimal metabolism in humans and is primarily eliminated unchanged via renal excretion. After oral administration, it rapidly absorbs and exhibits dose-dependent plasma concentrations. Within 48 hours, 64.5-89.9% of the administered dose is recovered unchanged in urine. Plasma protein binding is approximately 31.0–31.7% in humans.
The public source identifies “Enerisant” as chemical compound. This brief keeps that definition visible, then builds a research path around Enerisant, chemical and compound.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Enerisant”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 21, 2025. The linked authority identifier is Q27276798. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
