Cyproheptadine /ˌsaɪprɵˈhɛptədiːn/, sold under the brand name Periactin or Peritol, is a first-generation antihistamine with additional anticholinergic, antiserotonergic, and local anesthetic properties.

Medical uses

Periactin (cyproheptadine) 4 mg tablets

Cyproheptadine is used to treat allergic reactions (specifically hay fever).^[4] It is also used to treat vasomotor mucosal edema, including vasomotor rhinitis and edema of the throat.
Has shown effectiveness in the treatment of nightmares including nightmares related to post traumatic stress disorder.^[5]^[6]
Has been used in the management of moderate to severe cases of serotonin syndrome, a complex of symptoms associated with the use of serotonergic drugs,^[7] such as selective serotonin reuptake inhibitors and monoamine oxidase inhibitors),^[8]^[9]^[10] and in cases of high levels of serotonin in the blood resulting from a serotonin-producing carcinoid tumor.^[11]^[12]
Can also be used as a preventive measure against migraine in children and adolescents.^[13]^[14]^[15]^[16]^[17] In Australia this is the only indication for which cyproheptadine is subsidised by the PBS.^[7]
Can relieve SSRI-induced sexual dysfunction^{[medical citation needed]} and drug-induced hyperhidrosis (excessive sweating).^[18]
Also used in the treatment of cyclical vomiting syndrome^[19]
Use of the drug can stimulate the appetite and may lead to weight gain, which is helpful for underweight people.^[20]
According to a small study, cyproheptadine hydrochloride has been found to improve sleep, calmness, as well as mood and energy levels, and to improve both negative and (sometimes even) positive psychotic symptoms in a subgroup of chronic schizophrenics who do not respond (either completely or sufficiently) to other therapies.^[21]
Cyproheptadine may improve akathisia in patients on antipsychotic medications.^[22]
In clinical trials in which cyproheptadine was used as an adjunct to antipsychotic treatment for patients with schizophrenia, an improvement in negative symptoms was seen.^[23]

Adverse effects

Adverse effects include^[1]^[2]

Sedation and sleepiness (often transient)
Dizziness
Disturbed coordination
Confusion

Hepatic (liver) side effects such as:

- Hepatitis

- Jaundice

- Hepatic failure

- Hepatic function abnormality

Epigastric distress
Anorexia
Nausea
Vomiting
Diarrhea
Anticholinergic side effects such as:

- Blurred vision

- Constipation

Urinary frequency
Early menses
Thickening of bronchial secretions
Tightness of chest and wheezing
Fatigue

Weight gain

Research has shown a suppression of growth hormone with doses of 8–12 mg per day taken for 5 days.^[24]

Overdose

Supportive measures such as gastric lavage or induced emesis are usually recommended in cases of overdose. The symptoms are usually indicative of CNS depression (or conversely CNS stimulation in some) and excess anticholinergic side effects. The LD₅₀ in mice is 123 mg/kg and 295 mg/kg in rats.^[1]^[2]

Pharmacology

Cyproheptadine is known to be an antagonist (or inverse agonist depending on the site in question) of the receptors listed in the table below.

Receptor/Transporter Protein	Binding affinity (K_i[nM]) towards cloned human receptors unless otherwise specified^[25]

Acronyms used:

Pharmacokinetics

Cyproheptadine is well-absorbed following oral ingestion, with peak plasma levels occurring after 1–3 hours.^[26] Its half-life when taken orally is approximately 8 hours.^[3]

Veterinary use

Cyproheptadine is used in cats as an appetite stimulant and as an adjunct in the treatment of asthma.^[27]^[28] Possible adverse effects include excitement and aggressive behavior.^[27] The elimination half-life of cyproheptadine in cats is 12 hours.^[28]

Cyproheptadine has been used successfully in treatment of Pituitary Pars Intermedia Dysfunction (PPID) in horses.^[29]
