Is there a generic Methazolamide 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 Methazolamide, across 5 DINs, of which 1 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 |
|---|---|---|---|---|
| AA PHARMA INC | 1 | 1 | METHAZOLAMIDE | Sourceable in Canada |
| STORZ, DIVISION OF WYETH-AYERST CANADA INC. | 2 | 0 | NEPTAZANE TABLETS 25MG USP, NEPTAZANE TABLETS 50MG | No marketed DIN |
| WYETH-AYERST CANADA INC. | 2 | 0 | NEPTAZANE TABLETS 25MG, NEPTAZANE TABLETS 50MG | 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.

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.

Is Methazolamide in shortage in Canada?
A Canadian shortage report is on file for a product containing this molecule: Resolved — reported by AA PHARMA INC, last seen 26 May 2026. A shortage on one presentation does not always affect every DIN of the molecule — the alternatives below list what else is marketed in Canada. Nexara can confirm current availability and identify substitutions or import options where permitted.
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.

Nexara Health supplies this product to licensed Canadian buyers — pharmacies, hospitals, clinics, licensed distributors, and clinical trial sponsors or their CROs.

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.
