Background

Meclizine is a histamine H1 antagonist with antiemetic and antivertigo properties. It is used in the symptomatic treatment of motion sickness and control of vertigo associated with vestibular system diseases. It also exhibits anticholinergic, central nervous system depressant, and local anesthetic effects.4 Commonly marketed under the brand name Antivert in the U.S., meclizine is available as oral tablets.

Pharmacodynamics

Meclizine works on the higher centres of the brain to reduce nausea, vomiting, or vertigo. It is effective against nausea and vomiting arising from many causes, including motion sickness and disorders affecting the vestibular system. The onset of action of meclizine is about 1 hour, with effects lasting between 8 to 24 hours.4 Meclizine is reported to cause drowsiness due to its anticholinergic actions.5

Mechanism of action

Vomiting is a centrally regulated reflex mechanism that initiates from the vomiting center and the chemoreceptor trigger zone (CTZ) located in the medulla. Motion sickness is also regulated by CTZ. The blood-brain barrier near the CTZ is relatively permeable to circulating mediators and CTZ can transmit impulses to vomiting center located in the brainstem. Different receptors responding to different factors, including histamine, 5-HT, enkephalins, substance P, and dopamine, are expressed along the brainstem to activate respective pathways and contribute to the control of vomiting. Histamine H1 receptors are expressed on the vestibular nuclei and nucleus of the solitary tract (NTS) that are activated by motion sickness and stimuli from the pharynx and stomach. When activated, H1 receptor signaling from these nuclei is transmitted to the CTZ and vomiting centre.3

Through its antagonistic action on the H1 receptors, meclizine primarily works by inhibiting signaling pathway transduction through histaminergic neurotransmission from the vestibular nuclei and NTS to the CTZ and medullary vomiting center.1 Meclizine may also decrease the labyrinth excitability and vestibular stimulation.4

Absorption

Most histamine H1 antagonists are reported to be readily absorbed following oral administration.4 Upon oral administration, the time to reach peak plasma concentrations (Cmax) of meclizine is about 3 hours post-dose, with the value ranging from 1.5 to 6 hours.6

Volume of distribution

The volume of distribution of meclizine in humans has not been fully studied. It is proposed that meclizine may be excreted into breast milk.4

Protein binding

There is limited data on the protein binding profile of meclizine.

Metabolism

There is limited human data on meclizine metabolism. According to the findings of in vitro studies, meclizine may undergo aromatic hydroxylation or benzylic oxidation mediated by the hepatic CYP2D6 enzyme.2

Route of elimination

Meclizine is excreted in the urine as metabolites and in the feces as unchanged drug.4

Half-life

Meclizine has a plasma elimination half-life of about 5-6 hours in humans.6

Clearance

There is limited data on the clearance of meclizine.

Toxicity

The oral and intraperitoneal LD50 in mouse are 1600 mg/kg and 625 mg/kg, respectively. The lowest published toxic dose (TDLo) in rats via the oral route is 800 mg/kg.MSDS

Symptoms of overdose mainly involve CNS depression with drowsiness, coma, and convulsions. Hypotension may also occur, particularly in the elderly. In children, anticholinergic effects and CNS stimulation, characterized by hallucinations, seizures, trouble sleeping, are more likely to occur. In case of overdose, symptomatic and supportive treatment is recommended. In case of recent ingestion, induction of emesis or gastric lavage should be initiated to limit further drug absorption. Although there is no known antidote to meclizine, physostigmine may be useful to counteract the CNS anticholinergic effects of meclizine.5

Antagonist
General Function
G-protein-coupled receptor for histamine, a biogenic amine that functions as an immune modulator and a neurotransmitter (PubMed:33828102, PubMed:8280179). Through the H1 receptor, histamine mediates the contraction of smooth muscles and increases capillary permeability due to contraction of terminal venules. Also mediates neurotransmission in the central nervous system and thereby regulates circadian rhythms, emotional and locomotor activities as well as cognitive functions (By similarity)

General Function
A cytochrome P450 monooxygenase involved in the metabolism of fatty acids, steroids and retinoids (PubMed:18698000, PubMed:19965576, PubMed:20972997, PubMed:21289075, PubMed:21576599). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase) (PubMed:18698000, PubMed:19965576, PubMed:20972997, PubMed:21289075, PubMed:21576599). Catalyzes the epoxidation of double bonds of polyunsaturated fatty acids (PUFA) (PubMed:19965576, PubMed:20972997). Metabolizes endocannabinoid arachidonoylethanolamide (anandamide) to 20-hydroxyeicosatetraenoic acid ethanolamide (20-HETE-EA) and 8,9-, 11,12-, and 14,15-epoxyeicosatrienoic acid ethanolamides (EpETrE-EAs), potentially modulating endocannabinoid system signaling (PubMed:18698000, PubMed:21289075). Catalyzes the hydroxylation of carbon-hydrogen bonds. Metabolizes cholesterol toward 25-hydroxycholesterol, a physiological regulator of cellular cholesterol homeostasis (PubMed:21576599). Catalyzes the oxidative transformations of all-trans retinol to all-trans retinal, a precursor for the active form all-trans-retinoic acid (PubMed:10681376). Also involved in the oxidative metabolism of drugs such as antiarrhythmics, adrenoceptor antagonists, and tricyclic antidepressants

General Function
Binds water, Ca(2+), Na(+), K(+), fatty acids, hormones, bilirubin and drugs (Probable). Its main function is the regulation of the colloidal osmotic pressure of blood (Probable). Major zinc transporter in plasma, typically binds about 80% of all plasma zinc (PubMed:19021548). Major calcium and magnesium transporter in plasma, binds approximately 45% of circulating calcium and magnesium in plasma (By similarity). Potentially has more than two calcium-binding sites and might additionally bind calcium in a non-specific manner (By similarity). The shared binding site between zinc and calcium at residue Asp-273 suggests a crosstalk between zinc and calcium transport in the blood (By similarity). The rank order of affinity is zinc > calcium > magnesium (By similarity). Binds to the bacterial siderophore enterobactin and inhibits enterobactin-mediated iron uptake of E.coli from ferric transferrin, and may thereby limit the utilization of iron and growth of enteric bacteria such as E.coli (PubMed:6234017). Does not prevent iron uptake by the bacterial siderophore aerobactin (PubMed:6234017)
