Non-opioid centrally acting analgesic API
Flupirtine Maleate API Manufacturer & Supplier in India
Apex Pharma API is a Flupirtine Maleate manufacturer and supplier based in India, producing bulk active pharmaceutical ingredient for pharmaceutical formulation companies and distributors. Flupirtine Maleate is a centrally acting, non-opioid analgesic used in pain-management formulations, and we manufacture it in-house at our Saykha GIDC plant to the documentation and quality standards B2B buyers rely on when qualifying a new supplier.
What is Flupirtine Maleate API?
Flupirtine (CAS No. 75507-68-5) is an aminopyridine-derivative compound that functions as a centrally acting, non-opioid, non-NSAID analgesic — a pharmacological profile that is genuinely uncommon among pain-management APIs. Its primary mechanism is as a selective neuronal potassium channel opener, specifically activating KCNQ/Kv7 channels, which reduces neuronal excitability; it also exhibits NMDA-receptor antagonist properties that contribute to its analgesic effect through a separate pathway. Flupirtine has been used clinically since the 1980s, first available in Europe, and is known internationally under several brand names including Katadolon.
Apex Pharma API supplies Flupirtine Maleate as the maleate salt of flupirtine, prepared to improve handling and processing. Because the compound does not carry the dependency profile associated with opioid analgesics, it has historically been of particular interest to formulators developing non-opioid pain-management products. We manufacture and supply the API itself, not the finished branded or generic product.
Flupirtine Maleate API manufacturing at Apex Pharma API
We have manufactured Flupirtine Maleate in-house since 2015 at our Saykha GIDC plant in Bharuch, on a single established route that keeps the impurity profile consistent between campaigns — an advantage that matters for a specialised molecule with a limited supplier base. Production runs in a 4 KL stainless-steel reactor, so we supply from evaluation samples through to repeat commercial volumes, and you buy directly from the plant that makes it with the QC team that released the batch on hand. Our complete product range and general sourcing process are covered on our API manufacturing page.
Applications and uses
Flupirtine Maleate API is used in the formulation of non-opioid, non-NSAID analgesic medicines for pain management. Its distinct mechanism — working through potassium-channel modulation and NMDA-receptor antagonism rather than the prostaglandin-inhibition pathway used by NSAIDs or the opioid-receptor pathway used by narcotic analgesics — makes it a pharmacologically distinct option for formulation companies building differentiated pain-management products. This is general pharmacological context for buyer understanding, not a claim about specific finished products manufactured by our customers.
Industries and customers we serve
Flupirtine Maleate API from Apex Pharma API is supplied to pharmaceutical formulation manufacturers developing analgesic products, to distributors supplying API onward within their own network, and to R&D and generic-development teams needing API for formulation trials ahead of scale-up. Our full buyer-segment breakdown is on the API manufacturing companies in India page.
Flupirtine Maleate API export and supply considerations
The market and regulatory status of flupirtine is not uniform globally and has changed over time in some regions, so a buyer sourcing Flupirtine Maleate API — whether directly or for onward export — should confirm the specific requirements and approval status of their destination market as part of their own regulatory due diligence. We supply non-regulated export markets, with export documentation prepared in-house. Share your destination and we will confirm what is required before you order.

Flupirtine Maleate API — frequently asked questions
What is Flupirtine Maleate API used for?
It is formulated into non-opioid, non-NSAID analgesic medicines for pain management, acting through a distinct potassium-channel and NMDA-receptor mechanism rather than the opioid or prostaglandin pathways.
What is the CAS number for Flupirtine Maleate?
75507-68-5. It is the maleate salt of flupirtine, an aminopyridine-derivative centrally acting analgesic.
Is Flupirtine an opioid?
No. It is classified as a non-opioid, non-NSAID analgesic, which is part of what makes it pharmacologically distinct from most other pain-management APIs.
What grades of Flupirtine Maleate API do you supply?
USP, EP and in-house specification grades, against the applicable monograph.
Is a Certificate of Analysis provided with each batch?
Yes. A batch-wise Certificate of Analysis is issued as standard with every despatch, alongside the MSDS, specification sheet and method of analysis.
Is a DMF available for Flupirtine Maleate?
DMF documentation is available on request — tell us your destination market and filing type and we will confirm what we can provide.
Does Apex Pharma API export Flupirtine Maleate?
Yes. We supply non-regulated export markets, with export documentation prepared in-house. The market and regulatory status of flupirtine varies by region, so confirm the requirements of your destination market before you order.
What is the minimum order quantity?
We supply from trial quantities upward. The commercial MOQ is confirmed against your grade and packaging requirement at quotation — it is not a fixed number across all buyers.
Can I request a sample before a bulk order?
Yes. Evaluation samples go out with a batch CoA so your QC team can check the material against your own specification before a PO is raised.
