What is CARDURA-1,2,AND 4?
CARDURA-1,2,AND 4 4 MG contains DOXAZOSIN (DOXAZOSIN MESYLATE) : 4 MG DOXAZOSIN (DOXAZOSIN MESYLATE) : 2 MG DOXAZOSIN (DOXAZOSIN MESYLATE) : 1 MG. It is listed in the Health Canada Drug Product Database under DIN 02231762, held by ASTRAZENECA CANADA INC, supplied as KIT ; TABLET for ORAL administration. Health Canada currently lists it as cancelled pre market, status dated 27-Jul-2023. 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 CARDURA-1,2,AND 4 used for?
CARDURA (doxazosin mesylate) is indicated in the treatment of mild to moderate essential hypertension, either as sole therapy or in association with a thiazide diuretic and/or other antihypertensive agents. CARDURA is also indicated for the treatment of symptoms of benign prostatic hyperplasia (BPH) in both hypertensive and normotensive patients.
Authorized indication as written in the Health Canada product monograph. For healthcare professionals and licensed purchasers; this is not medical advice.
How much does Doxazosin cost around the world?
Doxazosin is listed on 8 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); Greece publishes a producer price (ex-factory); Romania publishes a max producer 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 | 4 | 79 | USD███.██ |
| Sweden | AIP (pharmacy purchase price) | 5 | 10 | SEK███.██ |
| Saudi Arabia | public | 8 | 8 | SAR███.██ |
| Bahrain | retail (max) | 4 | 6 | BHD███.██ |
| South Africa | single exit price | 6 | 6 | ZAR███.██ |
| Greece | producer price (ex-factory) | 4 | 4 | EUR███.██ |

| United Kingdom | hospital | 3 | 3 | GBP███.██ |
120 pack listings across 37 brand entries and 8 price bases, refreshed 03 Sep 2026. Ranges span every Doxazosin 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 Doxazosin 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.
10 holders have a Canadian DIN containing Doxazosin, across 28 DINs, of which 9 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 | 4 MG |
|---|---|
| Dosage form | KIT ; 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.

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 CARDURA-1,2,AND 4 called?
The same molecule, Doxazosin, 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 |
|---|---|---|
| Alfadil® | Latin | Sweden |
| CARDURA | Latin | Bahrain |
| DOSIN | Latin | Bahrain |
| Doxazosin Actavis | Latin | Sweden |
| Doxazosin Ebb | Latin | Sweden |

| Doxazosin STADA® | Latin | Sweden |
| Carzin Xl | 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 pre 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.
