Prescribing-label excerpts

Cyproheptadine Hydrochloride

Reference for: Cyproheptadine Hcl. Source presentation: solution. Source route: oral.

The source label presents its clinical-pharmacology findings together. These selected passages retain the source’s study context; the full label provides the complete discussion.

Clinical pharmacology

Cyproheptadine is a serotonin and histamine antagonist with anticholinergic and sedative effects. Antiserotonin and antihistamine drugs appear to compete with serotonin and histamine, respectively, for receptor sites.

Pharmacokinetics and Metabolism:After a single 4 mg oral dose of 14C-labeled cyproheptadine HCI in normal subjects, given as tablets or syrup, 2-20% of the radioactivity was excreted in the stools. Only about 34% of the stool radioactivity was unchanged drug, corresponding to less than 5.7% of the dose. At least 40% of the administered radioactivity was excreted in the urine. No detectable amounts of unchanged drug were present in the urine of patients on chronic 12-20 mg daily doses of cyproheptadine syrup. The principal metabolite found in human urine has been identified as a quaternary ammonium glucuronide conjugate of cyproheptadine. Elimination is diminished in renal insufficiency.

Selected passages from the cited U.S. prescribing label. The studies concern the source product and populations named in each passage; they do not establish Walter-product bioequivalence, an approved indication, or the kinetics of another fixed combination. Tables and the full prescribing information remain available in the source.

Common questions

Before you request a quotation.

Cyproheptadine Hcl 2 mg / 5 ml Syrup

What is listed in the catalogue?

The catalogue lists Cyproheptadine Hcl 2 mg / 5 ml as syrup in its respiratory & allergy navigation area and non-beta-lactam manufacturing stream.

How do you confirm manufacturing availability?

Send Walter your requirement for Cyproheptadine Hcl 2 mg / 5 ml Syrup. The team reviews the applicable product permission and unit, formulation and equipment fit, testing, packaging and production schedule before confirming the manufacturing scope in writing. Request the relevant product and facility documents with your enquiry.

What do I need for a quotation?

Share the exact composition and strength, syrup presentation, target market, initial quantity, preferred pack and timing. Identify whether this is a new product, development brief or transfer.

The quotation must confirm MOQ, inclusions, prerequisites and lead time for the proposed product and site.

What is needed for Indian and export markets?

For India, share the intended brand or institutional supply requirement, pack sizes, initial order quantity and artwork needs for Cyproheptadine Hcl 2 mg / 5 ml Syrup. Confirm the applicable product permission, manufacturing unit and labelling requirements with the team.

For export, identify each destination country, proposed pack, language and registration or dossier requirements. Ask which product-specific quality and stability documents are available. Container compatibility and destination-market requirements need review; a catalogue record does not establish export registration or a shelf-life commitment.
