Cyclizine is an antihistamine drug used to treat nausea, vomiting and dizziness associated with motion sickness, vertigo and post-operatively following administration of general anaesthesia and opioids.
Contents
Indications
Nausea, vomiting and dizziness associated with motion sickness, vertigo and post-operatively following administration of general anaesthesia and opioids. It is sometimes given in hyperemesis gravidarum (morning sickness) although the manufacturer advises avoid in pregnancy. Off licence use often occurs with specialists in hospitals to treat inpatients who have become severely dehydrated in pregnancy. An off-label use is as an opioid/opiate potentiator.[1]
The drug Diconal is a combination of cyclizine with the opioid dipipanone.[2] Dipipanone is a schedule I controlled substance in the US, due to its high abuse potential.
Contraindications
Its antimuscarinic action warrants caution in patients with prostatic hypertrophy, urinary retention, or glaucoma. Liver disease exacerbates its sedative effects.[1]
Adverse effects
Common (over 10%) – Drowsiness, xerostomia (dry mouth)
Uncommon (1% to 10%) – Headache, psychomotor impairment, and antimuscarinic effects such as urinary retention, diplopia (blurred vision), dermatitis, and gastro-intestinal disturbances.
Rare – Hypersensitivity reactions (bronchospasm, angioedema, anaphylaxis, rashes and photosensitivity reactions), extrapyramidal effects, dizziness, confusion, depression, sleep disturbances, tremor, liver dysfunction and hallucinations
Formulations
As cyclizine hydrochloride 50 mg tablets and cyclizine lactate solution for intramuscular or intravenous injection (brand names: Valoid[1] in UK and Marezine, Marzine and Emoquil in US). Cyclizine HCl 25 mg is marketed as Bonine for Kids in the US.[3]
Pharmacology
Cyclizine is a piperazine derivative with histamine H1-receptor antagonist (antihistamine) activity. The precise mechanism of action in inhibiting the symptoms of motion sickness is not well understood. It may have effects directly on the labyrinthine apparatus and on the chemoreceptor trigger zone. Cyclizine exerts a central anticholinergic (antimuscarinic) action.[1]
History
Cyclizine was developed in the American division of pharmacy company Burroughs Wellcome (today GlaxoSmithKline) during a research involving many drugs of the antihistamine group. Cyclizine was quickly clinically found as a potent and long-acting antiemetic. Company named the substance – or more precisely cyclizine's hydrochloride form which it usually appears in – "marezine hydrochloride" and started to sell it in the United States under trade name Marezine. Selling was begun in France under trade name Marzine in 1965.[4][5]
The substance received more credit when NASA chose it as a space antiemetic for the first occupied moon flight. Cyclizine was introduced to many countries as a common antiemetic. It is an over-the-counter drug in many countries because it has been well tolerated, although it has not been very much studied.[4]
Recreational use
Some people using methadone recreationally combine cyclizine with their methadone dose, a combination that is known to produce strong psychoactive effects.[6] It has also been used recreationally by teenagers for its anticholinergic effects to induce hallucinations.[7]
