Pregabalin API: uses, applications and what to check on the specification sheet

A plain-language guide for formulators and procurement teams evaluating Pregabalin suppliers — indications, grade differences, impurity considerations and the documentation to ask for.

What Pregabalin is used for

Pregabalin (CAS 148553-50-8) is a gamma-aminobutyric acid (GABA) analogue in the gabapentinoid class, acting on the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system. Formulators use it in medicines for neuropathic pain (including diabetic peripheral neuropathy and postherpetic neuralgia), as adjunctive therapy for partial-onset seizures, and in fibromyalgia and generalized anxiety disorder formulations depending on the approved indication in a given market. It is marketed globally under the brand name Lyrica, and buyers researching “Lyrica API” are typically looking for this same compound. For full specification and sourcing detail, see our Pregabalin API product page.

Grade differences that actually change your filing

Pharmacopoeial grade (IP/BP/USP/EP) is not a formality — it determines which impurity limits, assay methods and identification tests your regulatory filing needs to reference. Confirm which grade you actually need before requesting a quote, since sourcing the wrong grade means re-filing later, not just a paperwork correction.

Regulatory status buyers often miss

Pregabalin carries Schedule V controlled-substance status under the US Controlled Substances Act — the least restrictive DEA schedule, but one that still affects manufacturing, distribution and import/export controls for US-bound supply. Scheduling status varies by destination market (the UK, for instance, classifies it differently), so confirm requirements for your specific export market rather than assuming US status applies universally. This is exactly the kind of detail that should be checked before, not after, you commit to a supplier — see our API sourcing and process overview for the full list of what to verify.

Impurity profile and route consistency

Route of synthesis affects the impurity profile you will see on a Certificate of Analysis — a supplier who changes synthetic route between batches without notifying you can introduce impurity shifts that trigger your own out-of-specification investigations downstream. Ask directly whether the route is fixed and whether you would be notified of any change.

Packaging and storage in practice

Standard packing is 1 kg, 5 kg and 25 kg HDPE drums with double LDPE liners; other configurations are available on request. Pregabalin should be stored in a tightly closed container, protected from light and moisture, at controlled room temperature. Confirm the exact pack size and any specific handling needs at enquiry stage.

Documentation to request before the first PO

• A Certificate of Analysis specific to the batch you would receive, not a generic specification sheet
• Current GMP certification type and scope — see our quality & certifications page for what to verify and how
• DMF or equivalent filing status if you are sourcing for a regulated export market — our documentation and DMF detail explains what to ask for (a DMF is filed for Pregabalin covering the IP, BP and USP grades)
• Confirmed scheduling / controlled-substance handling documentation for your specific destination market

If you are also sourcing other CNS / neurology APIs

If Pregabalin is one of several neurology-focused APIs you are sourcing, our Lacosamide API specifications guide and Metaxalone API sourcing guide cover the same level of documentation and specification detail for two other compounds commonly sourced alongside it.

A short checklist before you commit

• Grade confirmed against your filing requirements
• Regulatory / scheduling status confirmed for your specific export market
• Sample CoA reviewed, not just a specification sheet
• Route consistency and change-notification policy confirmed

Frequently asked questions

Is Pregabalin the same compound as Lyrica? Lyrica is the original brand name; the active pharmaceutical ingredient itself is Pregabalin, supplied as bulk API rather than a finished formulation.

Is Pregabalin API sourcing affected by its controlled-substance status even for domestic Indian use? Controlled-substance scheduling is generally market-specific — Schedule V status applies to US-bound supply; confirm requirements separately for your actual destination market rather than assuming a single global standard.

What is the difference between buying Pregabalin as a standard catalogue product versus a custom order? A standard order sources an already-manufactured, validated specification; a custom requirement (different grade, different scale) may fall under a contract manufacturing or CDMO conversation instead.

Can I request a sample before placing a bulk order? Yes — evaluation samples are issued with a batch Certificate of Analysis so your QC team can test against your own specification before committing to a bulk order.
