APO-SILDENAFIL R 20 MG — DIN 02418118

SILDENAFIL (SILDENAFIL CITRATE) : 20 MG · APOTEX INC · TABLET · wholesale supply in Canada

Health Canada status: DORMANT

What is APO-SILDENAFIL R?

APO-SILDENAFIL R 20 MG contains SILDENAFIL (SILDENAFIL CITRATE) : 20 MG. It is listed in the Health Canada Drug Product Database under DIN 02418118, held by APOTEX INC, supplied as TABLET for ORAL administration. Health Canada currently lists it as dormant, status dated 25-Aug-2019. Nexara Health is a licensed Canadian wholesale distributor (DEL 3-002896-A). This DIN is not currently being marketed in Canada, so it is sourced to order where a compliant route exists rather than held in stock.

What is APO-SILDENAFIL R used for?

Treatment of primary pulmonary arterial hypertension (PPH) or PAH secondary to connective tissue disease (CTD) in adult patients with WHO functional class II or III.

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 Antihypertensives For Pulmonary Arterial Hypertension 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.

7 holders have a Canadian DIN containing Antihypertensives For Pulmonary Arterial Hypertension, across 8 DINs, of which 5 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.

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.

Health Canada DPD record Approved product monograph (PDF)

How is it administered?

Recommended dose is 20 mg three times a day (TID) taken approximately 6 to 8 hours apart with or without food.

Included because it drives pack selection and wastage. Consult the monograph.

Contraindications

Nitrate therapy, hypersensitivity, previous NAION episode, potent CYP3A4 inhibitors, sickle cell anaemia (secondary PAH), severe hepatic impairment, recent stroke/MI, unstable angina, riociguat.

Warnings and precautions

Pulmonary veno-occlusive disease, NAION (vision loss), sudden hearing loss, hypotension, priapism, bleeding disorders, and potential for serious cardiovascular events.

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.

How can I get it?

This DIN is dormant — it holds a Health Canada authorization but is not currently being marketed in Canada, so it cannot simply be ordered from Canadian stock. Where a patient need exists, supply may be possible through exceptional importation or the Special Access Programme, subject to Health Canada's requirements and the prescriber's application. Nexara can advise on the route and on marketed alternatives.

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.
