Health Canada status: CANCELLED POST MARKET
What is DARVON-N?
DARVON-N 100 MG contains DEXTROPROPOXYPHENE NAPSYLATE : 100 MG. It is listed in the Health Canada Drug Product Database under DIN 00261432, held by PALADIN PHARMA INC., supplied as CAPSULE for ORAL administration. Health Canada currently lists it as cancelled post market, status dated 23-Dec-2010. 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 DARVON-N used for?
Darvon-N is indicated for the relief of mild to moderate pain.
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 Dextropropoxyphene 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.
3 holders have a Canadian DIN containing Dextropropoxyphene, across 3 DINs, of which 0 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 |
|---|---|---|---|---|
| NOVOPHARM LIMITED | 1 | 0 | NOVO-PROPOXYN CAP 65MG | No marketed DIN |
| PALADIN PHARMA INC. | 1 | 0 | DARVON-N | No marketed DIN |
| PENDOPHARM DIVISION OF PHARMASCIENCE INC | 1 | 0 | 642 TAB | 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 | 100 MG |
|---|---|
| Dosage form | CAPSULE |
| Route | ORAL |
| Pack configuration (monograph) | null |
| Storage | 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.

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
0 of 3 Canadian DINs for this molecule are currently marketed. Marketed products are listed first.
| Product | Strength | Form | Holder | Health Canada status | DIN |

2 · Same class — other molecules in ATC N02AC
| Molecule | Canadian brands | DINs | Marketed | Sourceable |
|---|---|---|---|---|
| Dextropropoxyphene, Comb Excl Psycholept | 692 TAB · 692 TABLET · DARVON N COMPOUND PULVULE 405 · NOVO-PROPOXYN COMPOUND CAP | 4 | 0 | Not in Canada |
| Dextropropoxyphene | 642 TAB · DARVON-N · NOVO-PROPOXYN CAP 65MG | 3 | 0 | Not in Canada |
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 DARVON-N called?
The same molecule, Dextropropoxyphene, 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 |
|---|---|---|
| Doxyfene | Latin | South Africa |
| Distalgesic | Latin | South Africa |
| Doloxene Plain | Latin | South Africa |
| Lentogesic | Latin | South Africa |
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.
