Cyproheptadine is a first-generation antihistamine that potently antagonizes the histamine H1 receptor (pKi = 9.42). It also antagonizes serotonin and muscarinic receptors at nanomolar concentrations. Cyproheptadine also inhibits the lysine methyltransferase SET7/9 (IC50 = 1 µM), suppressing the expression of estrogen receptor α in human breast cancer MCF-7 cells.

Calculation results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.

Serotonin Syndrome Triggered by Overuse of Caffeine and Complicated With Neuroleptic Malignant Syndrome: A Case Report
Cureus 2022 Feb 21;14(2):e22468.PMID:35345760DOI:PMC8942071
Serotonin syndrome is a rare complication occurring in patients with psychiatric disorders that are treated with selective serotonin reuptake inhibitors (SSRIs). There are various triggers for serotonin syndrome, including non-SSRI antidepressants. In rare cases, serotonin syndrome may be triggered by nonmedicinal foods, such as coffee. The patient described in this case report was a 65-year-old woman with a past medical history of major depression and a diagnosis of Parkinson's disease who presented to our medical center with chief complaints of nausea, vomiting, and drowsiness. She had previously been prescribed paroxetine hydrochloride hydrate for depression, and she was prescribed levodopa and carbidopa for Parkinson's disease. She also drank 20 cups of coffee in a short period of time two days prior to admission due to excessive sleepiness. She was diagnosed with serotonin syndrome based on her clinical symptomology, which included diaphoresis, mydriasis, fine tremor, myoclonus, hypertension, and tachycardia. She was treated with diazepam and Cyproheptadine hydrochloride hydrate. Later, she experienced muscle pain with increased creatinine kinase levels after she failed to take levodopa and carbidopa. These findings were suggestive of neuroleptic malignant syndrome. The patient was treated with supportive care. Excessive coffee intake triggers serotonin syndrome by promoting 5-hydroxytryptamine (serotonin) secretion. Patients with psychiatric diseases that necessitate treatment with SSRIs should be educated regarding caffeine consumption. Moreover, patients presenting with agitation and drowsiness should be evaluated for serotonin syndrome within the differential diagnosis. Patients with depression and Parkinson's syndrome should be evaluated for associated comorbidities, particularly serotonin syndrome and neuroleptic malignant syndrome.
