One DIN can cover more than one pack size, and the pack — not the DIN — is what gets priced, shipped and invoiced. Before an order line is unambiguous Nexara needs the strength, the pack size and the presentation.
What can be used instead?
Other Canadian products sharing ATC code C01DA14 ISOSORBIDE MONONITRATE. 3 of 8 DINs in this group are currently marketed — marketed products are listed first, because that is what can actually be bought. These tables describe supply, not clinical equivalence: substitution rests with the prescriber or pharmacist, and interchangeability is determined provincially.

Who else supplies ISOSORBIDE MONONITRATE worldwide?
Nexara tracks national medicine registries and published price lists across multiple markets. ISOSORBIDE MONONITRATE appears in 2801 registered pack listings across 13 markets, published on 12 different national price bases. Where a Canadian route is closed, that is where an alternative route of supply starts — subject to the import rules in both countries.
Registered listings are not stock. Ask us to confirm what can actually be sourced for your order.
How much does ISOSORBIDE MONONITRATE cost around the world?
ISOSORBIDE MONONITRATE is listed on 2 national price registers Nexara tracks, across 6 pack listings published on 2 different price bases. What each country publishes is set out below.
| Market | What that country publishes | Brands listed | Pack listings | As of |
|---|---|---|---|---|
| Greece | producer price (ex-factory) | 5 | 5 | 03 Sep 2026 |
| Bahrain | retail (max) | 1 | 1 | 01 Sep 2026 |
Why there are no figures here. These bases are not comparable. A Brazilian ex-factory ceiling, a Belgian pharmacy public price and a Japanese reimbursement rate answer three different questions, and none of them is what a product lands in Canada for. Putting them side by side would mislead in both directions, so Nexara publishes where a molecule is listed and on what basis, and quotes the delivered Canadian price per order.
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.
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.
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.
