Who a prescription drug may lawfully be sold to

The rules that govern the trade, not the sale to you

Most writing about buying medicine online is about the last step, from a seller to a patient. There is a whole body of law about the steps before that, and it is where a vial's history is either recorded or lost.

The regulations state their own aim. They exist "to protect the public against drug diversion by establishing procedures, requirements, and minimum standards for the distribution of prescription drugs and prescription drug samples."

Their scope covers reimportation, wholesale distribution of prescription drugs "including both bulk drug substances and finished dosage forms," and the trade in drugs bought by hospitals or donated to charities.

None of this is visible on a product page. It is the machinery that decides whether a legitimate chain of custody exists behind one.

What wholesale distribution is defined to be

The defined term is broader than the everyday word, and its exclusions are the useful part.

Wholesale distribution means "distribution of prescription drugs to persons other than a consumer or patient." So the moment a transaction is not to a patient, this rulebook is in the frame.

A list of exclusions then carves out ordinary conduct. Intracompany sales, transfers among hospitals under common control, sales for emergency medical reasons, and dispensing under a prescription are all outside the definition.

Two more exclusions are worth noticing. Distribution of drug samples by manufacturers' and authorized distributors' representatives is excluded, and so are returns conducted by a hospital, health care entity or charitable institution.

The document that has to travel with an unauthorized sale

This is the central requirement, and it turns on a single status: whether the seller is the manufacturer's own distributor.

An authorized distributor of record is defined as "a distributor with whom a manufacturer has established an ongoing relationship to distribute such manufacturer's products." An ongoing relationship needs a written agreement, for a period of time or a number of shipments.

Where the seller is not one, a document has to change hands first. Before completing the distribution, the seller "shall provide to the purchaser a statement identifying each prior sale, purchase, or trade of such drug."

The contents are itemized. The drug's names, dosage, container size, number of containers, and lot or control numbers all go in. So does "The business name and address of all parties to each prior transaction involving the drug, starting with the manufacturer." The date of each previous transaction goes in as well.

The one thing here a member of the public can ask for

Almost every duty in this part runs between businesses. One does not.

Every manufacturer has to keep a current written list of all its authorized distributors of record at its corporate offices, and keep it updated on a continuing basis.

The list has to say how far each distributor's authorization goes, specifying whether it covers "the manufacturer's full product line or only particular, specified products."

And the list is public. The manufacturer "shall make its list of authorized distributors of record available on request to the public for inspection or copying," though it may charge reasonable copying fees. That is a real, checkable action for an approved product with a named manufacturer.

Drugs that may not be resold at all

A separate prohibition covers product that entered the system at an institutional price, and it is written as a flat rule with exceptions.

No person may sell, purchase or trade, or offer to, any prescription drug that was "Purchased by a public or private hospital or other health care entity." The same prohibition covers a drug "Donated or supplied at a reduced price to a charitable organization."

The exceptions are specific rather than general. Group purchasing arrangements, transfers among entities under common control, emergency medical reasons, dispensing under a valid prescription, and government-owned facilities dealing with each other.

Returns are handled separately and conditionally. A return is exempt only where a credit memo records the parties, the product name and lot number, the quantity and the date, with a copy sent to the manufacturer and proper storage conditions documented.

What a sample is, and why the label does not decide it

A drug sample has a definition, and it is about intent rather than packaging. It means "a unit of a prescription drug that is not intended to be sold and is intended to promote the sale of the drug."

Samples have to be traceable. The lot or control number goes on the sample unit label and on the outside container, and records must be sufficient to track sample units "to the point of the licensed practitioner."

Each unit must also be labeled to show what it is, and the regulation gives its own examples: "sample," "not for sale," "professional courtesy package."

Then comes the sentence that closes the loophole. Any article that is a drug sample as defined "that fails to bear the label required in this paragraph (c) is a drug sample." Removing the marking does not change what it is.

Where samples may go, and where they may not

The delivery rules are strict, and they are all built around a licensed prescriber asking first.

A sample may go by mail or common carrier to a practitioner licensed to prescribe that drug, or at that practitioner's written request to a hospital or health care entity pharmacy.

Four conditions attach. The practitioner submits a written request before delivery. The sender verifies with the state authority that the practitioner is licensed to prescribe the product. The recipient signs a receipt on delivery. The receipt goes back to the sender.

The written request itself has to carry the practitioner's name, address, professional title and signature, their state license or authorization number, the drug name and strength, the quantity, the manufacturer, and the date.

How to use this when a source looks unusual

None of these documents is addressed to a patient, so the honest summary is that a buyer cannot audit a chain of custody from the outside. Three things still follow.

A product offered as surplus, as clinic stock, or as having come from a hospital is describing exactly the transaction the resale prohibition names. The exceptions to that prohibition are institutional, and none of them is a consumer sale.

A unit marked as a sample is not ordinary sellable stock, and an unmarked unit that was a sample remains one. The marking is evidence, not the definition.

And for an approved product with a named manufacturer, the list of authorized distributors of record is public on request. That is the single thread in this part that a reader can actually pull.
