Health Canada status: MARKETED
What is PROCYSBI?
PROCYSBI 25 MG contains CYSTEAMINE (CYSTEAMINE BITARTRATE) : 25 MG. It is listed in the Health Canada Drug Product Database under DIN 02464705, held by AMGEN CANADA INC, supplied as CAPSULE (DELAYED RELEASE) for ORAL administration. Health Canada currently lists it as marketed, status dated 17-Apr-2025. Nexara Health is a licensed Canadian wholesale distributor (DEL 3-002896-A) and can source this product for hospitals, pharmacies and clinics. Availability and lead time are confirmed per order.
What is PROCYSBI used for?
PROCYSBI (cysteamine delayed-release capsules) is indicated for the treatment of nephropathic cystinosis. PROCYSBI treatment should be initiated under the supervision of a physician experienced in the treatment of cystinosis.
Authorized indication as written in the Health Canada product monograph. For healthcare professionals and licensed purchasers; this is not medical advice.
Is there a generic Mercaptamine in Canada, and who makes it?
Every market authorization holder with a Canadian DIN for this molecule, and how many of their listings Health Canada currently shows as marketed.
Only one market authorization holder has a Canadian DIN containing Mercaptamine — 2 DINs, of which 2 are currently marketed. There is no second Canadian source today, so a supply interruption on this holder has no domestic substitute at the same molecule.
| Market authorization holder | DINs | Marketed | Brand names | Position |
|---|---|---|---|---|
| AMGEN CANADA INC | 2 | 2 | PROCYSBI | Sourceable in Canada |
Health Canada’s Drug Product Database does not flag which listing is the originator and which are subsequent-entry products, so Nexara does not label them here. Interchangeability is determined provincially, not federally — confirm for your province before a formulary switch. Nexara can confirm which of these is actually obtainable, and on what lead time, per order.
How is it supplied and stored?
Pack configuration, storage class and the handling constraints that drive cold-chain planning. One DIN can cover more than one pack size, and the pack — not the DIN — is what gets priced, shipped and invoiced.
| Strength on the label | 25 MG |
|---|---|
| Dosage form | CAPSULE (DELAYED RELEASE) |
| Route | ORAL |
| Pack configuration (monograph) | null |
| Storage | null |
Before an order line is unambiguous Nexara needs the strength, the pack size and the presentation.

Health Canada record and identifiers
The regulatory facts straight from the Drug Product Database, plus every identifier form Nexara accepts on a purchase order. A DIN written without its leading zeros is the commonest reason an order line fails to match.

What can be used instead?
Alternatives on every axis a buyer actually considers — the same molecule in another presentation, the same class, an adjacent class, or a fixed-dose combination. Every row is led by the marketed DIN count, because that is what can be bought this week.
1 · Same molecule, other Canadian presentations
2 of 2 Canadian DINs for this molecule are currently marketed. Marketed products are listed first.
| Product | Strength | Form | Holder | Health Canada status | DIN |
|---|---|---|---|---|---|
| PROCYSBI | 75 MG | CAPSULE (DELAYED RELEASE) | AMGEN CANADA INC | MARKETED | 02464713 |
2 · Same class — other molecules in ATC A16AA
| Molecule | Canadian brands | DINs | Marketed | Sourceable |
|---|---|---|---|---|
| Levocarnitine | CARNITOR · ODAN LEVOCARNITINE | 4 | 4 | Yes |
| Metreleptin | MYALEPTA | 3 | 3 | Yes |
| Mercaptamine | PROCYSBI | 2 | 2 | Yes |
| Betaine | CYSTADANE | 1 | 1 | Yes |
| Carglumic Acid | CARBAGLU | 1 | 1 | Yes |
A molecule with zero marketed DINs cannot be sourced domestically, however many approvals it holds — if one of these sits on a formulary or in an older protocol, that is the line to check.
3 · Adjacent classes in ATC A16A
| ATC subgroup | Molecules | DINs | Marketed |
|---|---|---|---|
| A16AX | Anethole Trithione · Eliglustat · Givosiran · Glycerol Phenylbutyrate · Lumasiran · +11 more | 39 | 28 |
| A16AB | Agalsidase Alfa · Agalsidase Beta · Alglucosidase Alfa · Asfotase Alfa · Avalglucosidase Alfa · +12 more | 26 | 22 |
Not clinical advice. These tables describe what can be supplied in Canada, not what should be prescribed. Substitution within or across classes is a prescriber and pharmacist decision, and interchangeability is determined provincially.
What else is PROCYSBI called?
The same molecule, Mercaptamine, is registered under other names elsewhere. Buyers and prescribers searching from outside Canada — or working from a foreign prescription or tender document — often know it by one of these:
| Name | Script | Registered in |
|---|---|---|
| Cystadrops | Latin | Iceland |
Names are taken from national medicine registers and published price lists. A product registered abroad is not authorized for sale in Canada unless it holds its own DIN; import is possible only through the routes Health Canada permits.
How can I get it?
Nexara Health supplies this product to licensed Canadian buyers — pharmacies, hospitals, clinics, licensed distributors, and clinical trial sponsors or their CROs. We confirm stock, pack size, expiry and pricing at the time of quotation. If the product is on backorder or in shortage, we identify equivalent alternatives and import options where permitted.
Ordering questions
Who can buy this from Nexara?
Licensed entities only. Nexara holds Health Canada establishment licence DEL 3-002896-A and ships only to a licensed address. Patients and unlicensed buyers are routed to a partner pharmacy.
Is there a minimum order?
Yes, set per product line and per pack multiple rather than on the order total, so you are never asked to buy a part-pack. The minimum for this line is confirmed with your quote.
What is the lead time?
Confirmed per order at quotation, and it depends on current stock position and whether the product is in shortage.
Why is there no price on this page?
Nexara quotes a delivered Canadian price per order, against a verified licence. Foreign list prices are published on incompatible bases and are not a guide to what any buyer can obtain here, so this page shows which markets list the molecule and on what basis, and nothing more.
Can Nexara supply this for a clinical trial?
Yes — comparator and background-therapy supply, including sourcing from other markets where a Canadian pack will not satisfy the protocol. Clinical trial supply.
