Health Canada status: CANCELLED POST MARKET

What is EXTRA STRENGTH CALCIUM CARBONATE 1000 MG?

EXTRA STRENGTH CALCIUM CARBONATE 1000 MG 1000 MG contains CALCIUM CARBONATE : 1000 MG. It is listed in the Health Canada Drug Product Database under DIN 02248373, held by VITA HEALTH PRODUCTS INC, supplied as TABLET for ORAL administration. Health Canada currently lists it as cancelled post market, status dated 31-Jul-2006. 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.

Is there a generic Calcium Carbonate 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.

6 holders have a Canadian DIN containing Calcium Carbonate, across 16 DINs, of which 0 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.

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.

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.

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.
