Medicine Supply & Shortage Intelligence | Alcatia Pharma

What Information Does a Pharmaceutical Wholesaler Need to Source a Medicine?

Written by Alcatia | Aug 10, 2026, 3:42:06 PM

When a medicine becomes difficult to obtain, the first instinct is often simply to ask:

“Can you source this product?”

But for a pharmaceutical wholesaler or specialist importer to investigate the requirement properly, a product name alone is rarely enough.

The exact strength, pharmaceutical form, quantity, timing and product requirements can completely change what supply options are available.

A clear sourcing request allows the wholesaler to search the right markets, identify appropriate stock more quickly and avoid wasting time investigating products that will not meet the pharmacy or procurement team's requirements.

This guide explains the information Alcatia Pharma needs when you ask us to source a medicine, and why each detail matters.

Having difficulty sourcing something?

 

What information should you provide when asking a wholesaler to source a medicine?

For most sourcing enquiries, the essential information is:

  • Medicine or active ingredient
  • Strength
  • Pharmaceutical form
  • Quantity required
  • Required-by date
  • Whether the requirement relates to a current shortage
  • Whether licensed or unlicensed supply is required, if known
  • Organisation and contact details

Additional information such as manufacturer, pack size, minimum shelf life or storage requirements can make the search considerably more precise.

The more complete the requirement, the easier it is to determine whether a viable source exists.

1. Medicine name or active ingredient

Start with the exact medicine you require.

This could be:

Generic name:
Aztreonam

Active ingredient:
Aztreonam

Brand name:
Where a particular branded medicine is required

Ideally, provide both the generic and brand name where relevant.

This helps avoid ambiguity, particularly where several products share similar names or where different manufacturers market the same molecule in different countries.

If you have the details of the product you normally purchase, include them.

2. Strength

Strength is essential.

For example:

Aztreonam 1 g

is a significantly more useful sourcing request than:

Aztreonam

The same medicine may be available in several strengths, and a shortage may affect one strength while another remains available.

Examples include:

  • 5 mg tablets
  • 20 mg/ml oral solution
  • 500 mg capsules
  • 1 g powder for solution for injection
  • 100 micrograms/dose inhaler

Where relevant, include the concentration as well as the total quantity in the container.

3. Pharmaceutical form

Tell the wholesaler exactly what dosage form is required.

Examples include:

  • Tablets
  • Capsules
  • Oral solution
  • Suspension
  • Cream
  • Ointment
  • Eye drops
  • Pre-filled syringe
  • Vial
  • Ampoule
  • Powder for solution for injection
  • Solution for infusion
  • Inhaler
  • Suppository

This matters because different formulations are not automatically interchangeable.

An internationally available tablet does not solve a requirement for an injectable medicine, even where the active ingredient and strength appear similar.

For injectable medicines, additional detail about the formulation or presentation can be particularly important.

4. Quantity required

Specify approximately how much stock you need.

This might be:

20 packs

or:

200 vials

rather than simply saying that you need the medicine urgently.

Quantity matters because international availability can vary significantly.

A supplier may be able to provide ten packs immediately but not 500. Conversely, a manufacturer or larger wholesaler may only consider supply above a particular volume.

Knowing the quantity at the beginning allows the sourcing team to focus on suppliers capable of fulfilling the actual requirement.

Packs, units or doses?

Where possible, be explicit.

For example:

50 packs of 10 vials

is clearer than:

50

If you only know the clinical requirement rather than the pack configuration, provide that information and the sourcing team can investigate the available pack sizes.

5. Required-by date

This is one of the most important pieces of information in any medicine sourcing enquiry.

Tell the wholesaler when you need the stock.

For example:

Required within 48 hours

Required by 21 August

Required within two weeks

International sourcing may involve:

  • supplier lead times;
  • regulatory processes;
  • export arrangements;
  • transport;
  • customs;
  • temperature-controlled distribution; and
  • final delivery.

A product may technically be available but not be capable of reaching the customer within the required timeframe.

Providing a realistic required-by date helps distinguish a viable sourcing option from one that is simply too slow.

6. Is the medicine currently in shortage?

Tell the supplier whether the request relates to a known UK medicine shortage.

Useful information can include:

  • a Medicine Supply Notification;
  • National Patient Safety Alert;
  • manufacturer communication;
  • wholesaler allocation;
  • discontinued product notice; or
  • another known supply restriction.

This provides context for the enquiry and can help the sourcing team understand whether alternative or international supply routes may be relevant.

You can still submit an enquiry if the medicine is not listed on a national shortage notice.

Local and regional supply difficulties often occur before, or without, a formal national notification.

7. Do you need licensed or unlicensed supply?

If you know the answer, tell us.

Typical responses might be:

Licensed UK supply only

Unlicensed import can be considered

Unsure

It is completely acceptable to select unsure.

You do not need to determine the appropriate regulatory route before contacting a specialist pharmaceutical wholesaler.

In many cases, the first stage of the search is establishing what supply routes actually exist.

If licensed UK stock is available, that may be the appropriate route to investigate first.

Where licensed supply cannot meet a genuine clinical need, an imported unlicensed medicine may sometimes become relevant, subject to the appropriate clinical, regulatory and local governance processes.

8. Manufacturer or brand requirements

If a particular manufacturer is required, state this clearly.

For example:

Manufacturer X only

or:

Any manufacturer can be considered

This distinction can dramatically widen or narrow the search.

During a shortage, procurement teams may sometimes be willing to consider an alternative manufacturer provided the product passes the appropriate quality and clinical assessment.

In other cases, the manufacturer may be essential because of:

  • patient requirements;
  • device compatibility;
  • excipients;
  • formulation;
  • continuity of treatment; or
  • local formulary restrictions.

If the manufacturer is a preference rather than an absolute requirement, make that clear too.

9. Pack size

Pack size is another useful detail.

For example:

30 tablets per pack

10 vials per pack

100 ml bottle

Overseas products frequently have different pack configurations from their UK equivalents.

A medicine normally supplied as a UK pack of 28 tablets might be marketed elsewhere in packs of 30, 50 or another quantity.

Knowing whether the pack size is essential or flexible helps the wholesaler assess more possible options.

10. Minimum shelf life

If your organisation has a minimum acceptable shelf-life requirement, include it from the beginning.

For example:

Minimum six months remaining shelf life on delivery

This is particularly important during shortages because the available international stock may already be part-way through its commercial shelf life.

Without a minimum requirement, a sourcing team may identify technically available stock that your organisation would subsequently be unable to accept.

If your normal shelf-life requirement can be relaxed for urgent shortage supply, indicate this where appropriate.

11. Storage and transport requirements

Tell the supplier about any specific storage requirements.

Examples include:

  • ambient;
  • refrigerated 2°C to 8°C;
  • frozen;
  • protection from light; or
  • another controlled condition.

Cold-chain products require different sourcing and logistics arrangements from ordinary ambient medicines.

International transportation can therefore have a significant impact on both lead time and cost.

For temperature-sensitive medicines, the sourcing team also needs to determine whether the proposed supply chain can maintain the required conditions throughout transit.

12. Country or market restrictions

Sometimes a procurement team may have restrictions relating to where a medicine can be sourced.

If so, tell the supplier.

For example:

  • EEA markets preferred;
  • specific countries acceptable;
  • particular markets excluded; or
  • no restriction subject to appropriate regulatory and quality assessment.

This can affect the number of viable supply options.

If you do not have a particular geographic requirement, there is usually no need to specify one. A specialist importer can search the appropriate international markets.

13. Product documentation requirements

For an imported or otherwise unfamiliar product, your pharmacy or quality team may require supporting documentation.

Depending on the product, this could include information relating to:

  • manufacturer;
  • marketing authorisation;
  • country of authorisation;
  • product specification;
  • storage requirements;
  • packaging;
  • labelling;
  • shelf life; or
  • supply-chain provenance.

If you know that particular documents will be required before the product can be approved, state this early.

It allows the sourcing team to establish whether the prospective supplier can provide them before significant time is spent progressing the enquiry.

14. Organisation details

A sourcing enquiry should identify the organisation requiring the medicine.

For example:

  • NHS hospital trust;
  • private hospital;
  • community pharmacy;
  • pharmaceutical wholesaler;
  • clinic;
  • healthcare provider; or
  • another authorised healthcare organisation.

The sourcing team will normally also need a named contact with a work email address and telephone number.

This is particularly important where an enquiry becomes urgent and questions need to be resolved quickly.

15. Any additional constraints

Medicine sourcing often involves requirements that are difficult to capture in a standard form.

Include anything that could determine whether a product is acceptable.

For example:

  • preservative-free formulation required;
  • latex-free device required;
  • specific route of administration;
  • particular container type;
  • English-language packaging preferred;
  • specific excipients must be avoided;
  • minimum number of doses;
  • specific brand currently used;
  • split delivery acceptable;
  • equivalent presentation can be considered.

These details can prevent the sourcing team from investigating stock that your organisation would ultimately reject.

The five most important pieces of information

If time is limited, provide at least these five things:

1. Medicine

What product do you need?

2. Strength

What exact strength or concentration?

3. Form

Tablet, vial, capsule, solution or another presentation?

4. Quantity

How much do you need?

5. Required-by date

When does it need to arrive?

With these details, a pharmaceutical sourcing team can usually begin investigating the requirement.

Everything else helps narrow the search.

Example of a weak sourcing request

Can you source aztreonam urgently?

There is not enough information here to conduct an efficient search.

The sourcing team would immediately need to ask:

  • Which strength?
  • Which formulation?
  • What quantity?
  • When is it required?
  • Is imported unlicensed supply acceptable?

Every additional round of questions costs time.

Example of a strong sourcing request

A much more useful enquiry would be:

Medicine: Aztreonam
Strength: 1 g
Form: Powder for solution for injection
Quantity: 100 vials
Required by: 18 August
Reason: Current UK supply shortage
Supply route: Unlicensed import can be considered
Minimum shelf life: Six months preferred

The sourcing team now has enough information to begin searching appropriate markets immediately.

What happens after a sourcing request is submitted?

Once Alcatia receives a requirement, the first step is to assess the request and investigate the available supply routes.

Depending on the medicine, this might include:

  1. Checking whether licensed UK stock can be identified.
  2. Reviewing alternative supply channels.
  3. Searching international markets.
  4. Identifying suitable manufacturers or products.
  5. Establishing available quantities.
  6. Checking indicative shelf life.
  7. Determining likely lead times.
  8. Reviewing the relevant regulatory route.
  9. Obtaining pricing.
  10. Gathering product information for the customer's assessment.

Where a potential option is identified, Alcatia can provide the relevant information to allow the procurement and pharmacy teams to determine whether the product meets their requirements.

A sourcing request does not itself guarantee supply. Availability can change quickly, particularly during widespread shortages.

Why precise sourcing requests matter during shortages

During a medicine shortage, multiple organisations may be searching for the same stock at the same time.

International quantities can therefore change rapidly.

The time spent clarifying a vague request can matter.

Providing the exact product requirement from the outset means a sourcing team can move more quickly from:

“What exactly do you need?”

to:

“Here are the potential supply options.”

For procurement teams dealing with shortages regularly, establishing a standard internal sourcing request template can therefore make the process significantly more efficient.

What if you do not know all the information?

Submit the enquiry anyway.

You may know that your usual wholesaler cannot supply the product without yet knowing:

  • whether an alternative manufacturer is acceptable;
  • whether unlicensed supply can be considered;
  • which overseas markets have stock; or
  • what pack sizes may be available.

That should not prevent the search from starting.

Provide everything you know and identify areas where there is flexibility.

A specialist wholesaler can then investigate the potential options and come back with the additional product information your team needs to make a decision.
