Korlym: how international patients access US-sourced specialty supply
Korlym (mifepristone) is coordinated by Reserve Meds for international patients through US-sourced, named-patient cross-border supply, working with your treating doctor.

Quick orientation
Korlym (mifepristone) is sponsored by Corcept Therapeutics and received first US FDA approval in 2012. It is delivered as oral, once daily. The US label covers control of hyperglycemia secondary to hypercortisolism in adult patients with endogenous Cushing syndrome who have type 2 diabetes mellitus or glucose intolerance and have failed surgery or are not surgical candidates. Mechanistically, Mifepristone in Cushing syndrome works as a glucocorticoid receptor antagonist.

Mechanism of action
Mifepristone in Cushing syndrome works as a glucocorticoid receptor antagonist. Unlike osilodrostat or levoketoconazole, it does not lower circulating cortisol; instead, it blocks the cortisol receptor in target tissues. The downstream effect in this population is improved glycemic control even though serum cortisol may remain elevated, which means standard cortisol-level monitoring does not apply.
Why Korlym routes via cross-border NPP internationally
Korlym is a US-specific brand with a narrow Cushing-with-hyperglycemia indication. Local formularies across MENA and South Asia generally stock racemic ketoconazole or, in larger centers, somatostatin analogues; Korlym is rarely listed. Adult endogenous Cushing patients with diabetes who are not surgical candidates often find no in-country route to a glucocorticoid-receptor antagonist and route to Korlym via named-patient import.
The patterns that produce cross-border demand for Korlym are consistent across destination countries: meaningful registration lag relative to the US label, indication-specific dosing complexity that makes substitution clinically risky, payer denial patterns that exclude newer or expanded indications, and the global specialty distribution model in which the originator manufacturer routes specialty supply through a small number of authorized US wholesalers. Reserve Meds sits inside that authorized supply lane, not outside it.
How Reserve Meds coordinates supply
Every Korlym case follows the same doctor-directed, document-first workflow:
- The treating physician issues a prescription and clinical justification letter.
- Reserve Meds clinical and regulatory review assesses indication fit and destination-country pathway eligibility.
- Country-specific named-patient or personal-import documentation is prepared, translated where required, and submitted to the destination-country regulator under the local lawful import framework.
- Supply is sourced from a US-licensed pharmaceutical wholesale partner with full serial traceability (a federal track-and-trace requirement) and unbroken chain of custody from US warehouse forward.
- Cold-chain handling is validated where applicable; temperature is monitored end-to-end with audit logs.
- Shipment is coordinated to the patient's treating physician or hospital pharmacy, not directly to consumers.
Reserve Meds does not handle controlled substances. We do not promise pharmacy assistance program enrollment, manufacturer copay support, or insurance reimbursement; those are different commercial frameworks aimed at US-domiciled patients.
Common cross-border destinations
Korlym cross-border demand concentrates in markets where US specialty supply is the most reliable path to the labeled indication. We publish destination-country deep-dives for selected countries; every other destination is coordinated case by case on the same workflow, with your treating doctor.
Across each of these destinations, three structural patterns repeat. First, the local regulator maintains a named-patient or personal-import framework precisely so clinicians can reach a labeled US therapy for individual patients whose case cannot wait for full local registration. Second, that framework is document-driven, which means the work of cross-border access is the work of preparing a defensible clinical and regulatory dossier rather than chasing inventory. Third, the destination-country specialist (the treating physician) signs the case in; Reserve Meds operates on top of that signature, not in place of it.
Real cost picture
Medicine price: quote on request. You get a written quote for your case before you commit. It is oral and not cold-chain critical, so logistics are simple. Reserve Meds quotes a firm price after the endocrinology dossier and monitoring plan are reviewed.
A formal Reserve Meds quote breaks out: drug cost; cold-chain 3PL handling where applicable; IOR, customs, and destination-country regulatory fees; certified translation of physician documentation; and the Reserve Meds coordination fee, quoted in writing for your case before you commit. No hidden charges. A written custom quote is issued after physician documentation is reviewed, before you commit.
Reserve Meds does not charge intake deposits. Patients pay the firm-quoted amount in full only after accepting the quote, with a defined refund posture for procurement failure or gross negligence as set out in the engagement documentation. Delivery or transit-failure outcomes are handled via insurance and replacement coordination rather than refund, because once a US procurement chain is committed, the drug is committed.
Manufacturer context and global distribution
Korlym is manufactured by Corcept Therapeutics. Like most US specialty therapies, it is routed through a narrow set of authorized specialty wholesalers under DSCSA (Drug Supply Chain Security Act) track-and-trace rules. That is the same supply lane US specialty pharmacies use; cross-border named-patient access works by attaching destination-country regulatory documentation to a shipment that originates inside that authorized lane, not by sourcing outside it. Counterfeit and parallel-trade exposure is concentrated outside that lane, which is precisely why Reserve Meds will not source from secondary or grey-market channels regardless of price.
Serial-number traceability is preserved end-to-end. Every Korlym pack or vial carries the US wholesaler's lot and serial-number documentation forward into the destination-country regulatory submission, which is what allows the destination regulator to verify provenance on inspection.
What your physician provides
For Reserve Meds to coordinate Korlym, the treating physician provides an endocrinologist-issued prescription, a clinical justification letter that documents endogenous Cushing syndrome with diabetes or glucose intolerance and surgical status, an explicit confirmation that the patient is not pregnant and is using effective contraception (a US boxed warning area), a hypokalemia and adrenal-insufficiency monitoring plan, and license verification. Reserve Meds does not substitute for treating-physician judgment, does not prescribe, and does not advise on individual patient suitability; that is the treating physician's role.
Common questions
Does Korlym lower cortisol?
No. Korlym blocks the glucocorticoid receptor in target tissues. Serum and urine cortisol typically remain elevated on therapy, so traditional cortisol monitoring does not apply.
Is Korlym used for Cushing patients without diabetes?
The US label is specifically for Cushing syndrome patients with type 2 diabetes or glucose intolerance who have failed surgery or are not surgical candidates. Other use is off-label.
What is the major contraception requirement?
Mifepristone is contraindicated in pregnancy. Effective contraception is required, and the destination regulator will typically incorporate this into named-patient documentation.
How is hypokalemia managed?
Korlym can cause hypokalemia. Potassium monitoring and supplementation are part of the standard monitoring plan.
Can Korlym be combined with cortisol-synthesis inhibitors?
Combination management is specialist-directed only.
Indicative timing
Time-to-first-dose for Korlym is dominated by destination-country regulatory turnaround on the named-patient or personal-import submission, not by US procurement (which is typically days, not weeks, for an authorized specialty wholesaler with serialized stock). In every market, a dossier that is complete on first submission avoids the most common delays. We give you a written timeline estimate for your case before you commit. Reserve Meds frames every Korlym timeline as an indicative range with a defined gating event (regulator acknowledgement), not as a guaranteed delivery date.
Subsequent cycles are materially faster than the first cycle because the regulatory file, physician credentials, and import authorization are already on record. For chronic-use therapies like Korlym, the first cycle carries the regulatory overhead; the rest is logistics.
Where Reserve Meds fits in
Reserve Meds is the named cross-border coordinator. A dedicated patient coordinator owns the case from intake through delivery, the clinical and regulatory teams handle the document chain, and a DSCSA-compliant specialty wholesaler is the source of every vial or pack. We work in service of the treating-physician relationship, not around it.
Patients deal with one case coordinator from intake through delivery. Physicians deal with a clinical-and-regulatory contact who speaks the language of the destination regulator and of US specialty pharmacy. That single-point-of-contact structure is deliberate: cross-border specialty access fails most often at the seams between parties, not inside any single step, and Reserve Meds is built to own the seams.
