Health Canada status: CANCELLED POST MARKET
What is ZADITOR?
ZADITOR 0.25 MG contains KETOTIFEN (KETOTIFEN FUMARATE) : 0.25 MG. It is listed in the Health Canada Drug Product Database under DIN 02279223, held by NOVARTIS PHARMACEUTICALS CANADA INC, supplied as SOLUTION for OPHTHALMIC administration. Health Canada currently lists it as cancelled post market, status dated 17-Jan-2012. 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 ZADITOR used for?
ZADITOR* (ketotifen fumarate ophthalmic solution) is indicated for: treatment of allergic conjunctivitis.
Authorized indication as written in the Health Canada product monograph. For healthcare professionals and licensed purchasers; this is not medical advice.
How much does Ketotifen cost around the world?
Ketotifen is listed on 9 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. Bahrain publishes a retail (max); Czechia publishes a max producer price (ex-factory); Greece publishes a producer price (ex-factory). 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 |
|---|---|---|---|---|
| Saudi Arabia | public | 19 | 19 | SAR███.██ |
| Greece | producer price (ex-factory) | 8 | 8 | EUR███.██ |
| South Africa | single exit price | 3 | 5 | ZAR███.██ |
| Romania | max producer price | 4 | 4 | RON███.██ |
| Bahrain | retail (max) | 3 | 3 | BHD███.██ |
| United States | acquisition | 1 | 3 | USD███.██ |
| Czechia | max producer price (ex-factory) | 1 | 2 | CZK███.██ |
| Iceland | max wholesale | 1 | 2 | ISK███.██ |
| United Arab Emirates | public | 1 | 1 | AED███.██ |
47 pack listings across 41 brand entries and 8 price bases, refreshed 03 Sep 2026. Ranges span every Ketotifen pack in that market, so a high figure is usually a larger pack rather than the same product.
Canada publishes no comparable public list price. For a delivered Canadian price on a licensed account, verify your licence — it takes about a minute.
Is there a generic Ketotifen 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.
4 holders have a Canadian DIN containing Ketotifen, across 5 DINs, of which 2 are currently marketed. Marketed count is the number that matters: an approval that is not marketed cannot be bought.
| Market authorization holder | DINs | Marketed | Brand names | Position |
|---|---|---|---|---|
| JAMP PHARMA CORPORATION | 2 | 1 | JAMP KETOTIFEN, JAMP KETOTIFEN OPHTHALMIC | Sourceable in Canada |
| LABORATOIRES THEA | 1 | 1 | ZADITOR | Sourceable in Canada |
| NOVARTIS PHARMACEUTICALS CANADA INC | 1 | 0 | ZADITOR | No marketed DIN |
| STERIMAX INC | 1 | 0 | KETOTIFEN OPHTHALMIC SOLUTION | No marketed DIN |
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 | 0.25 MG |
|---|---|
| Dosage form | SOLUTION |
| Route | OPHTHALMIC |
| Pack configuration (monograph) | Multi dose containers: 5 mL; Single dose containers: 0.4 mL, Blocks of 5 single dose containers are each packed in a blister. Carton boxes of 30 single dose containers |
| Storage | Multi dose containers: Store between 4°C and 25°C. Single dose containers: Store between 4°C and 25°C. After opening a blister, unused single dose containers may be stored for 4 weeks. Single dose containers may be stored outside the blister in the outer carton for 3 months. |
Before an order line is unambiguous Nexara needs the strength, the pack size and the presentation.

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.

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.

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 ZADITOR called?
The same molecule, Ketotifen, 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 |
|---|---|---|
| Zaditen | Latin | South Africa |
| Ketotifen | Latin | Iceland |
| KETOTIFEN AL | Latin | Czechia |
| Adco-Ketotifen | Latin | South Africa |

| ASMAFORT | Latin | Bahrain |
| Fenobat | Latin | Saudi Arabia |
| HISTOFEN | Latin | Saudi Arabia |
| Keta | Latin | Saudi Arabia |
| PROFILAR | Latin | Bahrain |
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.
