OPTIMINE TAB 1MG 1 MG — DIN 00355666

AZATADINE MALEATE : 1 MG · SCHERING-PLOUGH CANADA INC · TABLET · wholesale supply in Canada

Health Canada status: CANCELLED POST MARKET

What is OPTIMINE TAB 1MG?

OPTIMINE TAB 1MG 1 MG contains AZATADINE MALEATE : 1 MG. It is listed in the Health Canada Drug Product Database under DIN 00355666, held by SCHERING-PLOUGH CANADA INC, supplied as TABLET for ORAL administration. Health Canada currently lists it as cancelled post market, status dated 04-Aug-2009. 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.

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.

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.

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.
