Health Canada status: CANCELLED POST MARKET
What is RATIO-SULFASALAZINE TAB 500MG?
RATIO-SULFASALAZINE TAB 500MG 500 MG contains SULFASALAZINE : 500 MG. It is listed in the Health Canada Drug Product Database under DIN 00685933, held by RATIOPHARM INC DIVISION OF TEVA CANADA LIMITED, supplied as TABLET for ORAL administration. Health Canada currently lists it as cancelled post market, status dated 01-Aug-2008. This Drug Identification Number is no longer authorized for sale in Canada, so Nexara does not supply it. The record is kept here because buyers still meet the number on old formularies, purchase orders and tender documents; Nexara can help identify an authorized alternative.
What is RATIO-SULFASALAZINE TAB 500MG used for?
null
Authorized indication as written in the Health Canada product monograph. For healthcare professionals and licensed purchasers; this is not medical advice.
How much does Sulfasalazine cost around the world?
Sulfasalazine is listed on 7 of the national price registers Nexara ingests. Each country publishes on a different basis, so those figures are not comparable with one another — or with a Canadian wholesale price.
What a market publishes matters more than the number it publishes. Australia publishes a ex-manufacturer; Greece publishes a producer price (ex-factory); Morocco publishes a PPV (public price). Comparing an ex-factory ceiling against a pharmacy public price tells you nothing about either, and comparing either against a Canadian landed cost tells you less.
| Market | Price basis published there | Brands | Packs listed | Range |
|---|---|---|---|---|
| United States | acquisition | 1 | 12 | USD███.██ |
| Australia | ex-manufacturer | 3 | 6 | AUD███.██ |
| United Kingdom | hospital | 3 | 3 | GBP███.██ |
| United Arab Emirates | public | 1 | 1 | AED███.██ |
| Greece | producer price (ex-factory) | 1 | 1 | EUR███.██ |
| Morocco | PPV (public price) | 1 | 1 | MAD███.██ |
| Saudi Arabia | public | 1 | 1 | SAR███.██ |
25 pack listings across 11 brand entries and 6 price bases, refreshed 08 Sep 2026. Ranges span every Sulfasalazine pack in that market, so a high figure is usually a larger pack rather than the same product.
This table is a regulatory record of where the molecule is listed. The DIN on this page is no longer authorized for sale in Canada, so Nexara does not quote it — see the alternatives above.
Is there a generic Sulfasalazine 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.
8 holders have a Canadian DIN containing Sulfasalazine, across 14 DINs, of which 5 are currently marketed. Marketed count is the number that matters: an approval that is not marketed cannot be bought.

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 | 500 MG |
|---|---|
| Dosage form | TABLET |
| Route | ORAL |
| Pack configuration (monograph) | null |

Pack detail is kept as a regulatory record. This DIN is no longer authorized for sale in Canada, so Nexara does not quote this pack.

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.

2 · Same class — other molecules in ATC A07EC
| Molecule | Canadian brands | DINs | Marketed | Sourceable |
|---|---|---|---|---|
| Mesalazine | 5-ASA · ASACOL · ASACOL 800 · MESALAMINE · +13 more | 29 | 18 | Yes |

| Olsalazine | DIPENTUM | 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 A07E
| ATC subgroup | Molecules | DINs | Marketed |
|---|---|---|---|
| A07EA | Betamethasone · Budesonide · Hydrocortisone · Tixocortol | 16 | 6 |
| A07EB | Cromoglicic Acid | 1 | 1 |
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 RATIO-SULFASALAZINE TAB 500MG called?
The same molecule, Sulfasalazine, 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 |
|---|---|---|
| Salazopyrin | Latin | Australia, Morocco |
| Pyralin EN | Latin | Australia |
| Salazopyrin-EN | Latin | Australia |
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.
Can this still be bought in Canada?
No. This Drug Identification Number is cancelled post market in Health Canada's Drug Product Database, so the product is no longer authorized for sale in Canada and Nexara does not supply it. This page is kept as a regulatory record.

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.
