Refer to adult dosingÂ
aripiprazole: it may increase the risk of hypotension with caroverine
asenapine: it may increase the risk of hypotension with caroverine
atazanavir: it may decrease the metabolism of caroverine
atenolol: it may increase the arrhythmogenic activities of caroverine
berotralstat: it may decrease the metabolism of caroverine
betaxolol: it may increase the arrhythmogenic activities of caroverine
bexagliflozin: it may increase the risk of hypoglycemia can be increased when caroverine
bisacodyl: it may decrease the therapeutic efficacy of caroverine
bisoprolol: it may increase the therapeutic efficacy of caroverine
castor oil: it may decrease the therapeutic efficacy of caroverine
celecoxib: it may increase the risk of hyperkalemia with caroverine
celiprolol: it may increase the arrhythmogenic activities of caroverine
Actions and SpectrumÂ
caroverine is an NMDA receptor antagonist. NMDA receptors are a type of glutamate receptor in the brain that plays a role in excitatory neurotransmission. Â
By blocking these receptors, caroverine can potentially reduce excessive excitatory signalling, which is thought to be involved in conditions like tinnitus and vertigo.

Contraindication/Caution:Â

Pregnancy consideration:Â
Pregnancy category: N/AÂ
Lactation: Excretion into human milk is unknown Â
Pregnancy Categories:        Â
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.Â
<b>Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women. Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.Â
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.Â
Category N: There is no data available for the drug under this category.Â
Pharmacology Â
caroverine has calcium channel-blocking properties. This means it can inhibit the influx of calcium ions into neurons. Calcium ions play a crucial role in neurotransmission and neuronal excitability. caroverine may help reduce abnormal neuronal firing associated with conditions like tinnitus.Â
PharmacodynamicsÂ
caroverine may have interactions with other neurotransmitter systems, such as the gamma-aminobutyric acid (GABA) system, which is the primary inhibitory neurotransmitter system in the central nervous system. Â
PharmacokineticsÂ
Absorption  Â
caroverine is absorbed through the gastrointestinal tract after oral administration. Â
DistributionÂ
caroverine is distributed throughout the body.Â
MetabolismÂ
caroverine undergoes metabolism primarily in the liver. Â
Elimination and excretionÂ
caroverine is eliminated from the body through the kidneys.Â
AdministrationÂ
caroverine is taken orally in the form of capsules. Â
Also administered through intravenous and intramuscular route.

Generic Name: caroverineÂ
Why do we use caroverine?Â
caroverine has been used in the treatment of tinnitus. Â
caroverine has been considered for the treatment of vertigo and vestibular disorders.  Â
caroverine is also indicated in the treatment of smooth muscle spasms.Â
