The storage rules a prescription drug travels under

What this rule is, and what it is not

The part applies to any person, partnership, corporation or business firm in a state that engages in wholesale distribution of human prescription drugs in interstate commerce.

Its stated purpose is to implement a 1987 statute by providing minimum standards, terms and conditions for the licensing by state licensing authorities of persons who engage in wholesale distribution in interstate commerce.

That phrasing matters. The rule is addressed to what a state licensing law has to contain. Its operative sections open with the words that the state licensing law shall include the following minimum requirements.

The licensing requirement itself is stated plainly. Every wholesale distributor in a state who engages in wholesale distributions of prescription drugs in interstate commerce has to be licensed by the state licensing authority before doing so.

The information a license application carries is specified too. It covers the licensee's name, full business address and telephone number, all trade or business names used, and the addresses, telephone numbers and contact persons for every facility used for storage, handling and distribution.

Ownership has to be named rather than summarized. The type of ownership is stated. For a partnership that means the name of each partner. For a corporation, the name and title of each officer and director along with the state of incorporation. For a sole proprietorship, the full name of the proprietor.

The building, and the security around it

Facilities where prescription drugs are stored, warehoused, handled, held, offered, marketed or displayed have to meet five conditions.

They have to be of suitable size and construction to facilitate cleaning, maintenance and proper operations. Storage areas have to be designed to provide adequate lighting, ventilation, temperature, sanitation, humidity, space, equipment and security conditions. There has to be a quarantine area. They have to be kept clean and orderly, and free from infestation by insects, rodents, birds or vermin of any kind.

The quarantine area has a specific job. It holds prescription drugs that are outdated, damaged, deteriorated, misbranded or adulterated, or that are in immediate or sealed secondary containers that have been opened.

Security is treated separately and in detail. Facilities have to be secure from unauthorized entry, with outside access kept to a minimum and well controlled, the outside perimeter well lit, and entry into areas where drugs are held limited to authorized personnel. An alarm system has to detect entry after hours.

One clause reaches beyond doors. A security system has to provide suitable protection against theft and diversion, and where appropriate, against theft or diversion facilitated or hidden by tampering with computers or electronic records.

Personnel are covered in a single sentence. State licensing authorities are to require that people employed in wholesale distribution have appropriate education or experience to take responsibility for positions related to compliance.

Temperature, and where the number comes from

The storage paragraph is short and points elsewhere for its numbers.

All prescription drugs have to be stored at appropriate temperatures and under appropriate conditions in accordance with requirements in the labeling of those drugs, or with requirements in the current edition of an official compendium.

Where no storage requirement has been established for a drug, the rule gives a default. The drug may be held at controlled room temperature, as defined in an official compendium, to help ensure that its identity, strength, quality and purity are not adversely affected.

The number is only half of it. Appropriate manual, electromechanical or electronic temperature and humidity recording equipment, devices or logs have to be used to document proper storage.

That is the sentence that turns a temperature into evidence. Without a log there is a claim about storage and nothing behind it, and the paragraph attaches the recordkeeping duty to all stored drugs.

The facility conditions carry the same theme from the other side. Storage areas have to be designed to provide adequate temperature and humidity along with lighting, ventilation, sanitation, space, equipment and security, which makes the environment a design requirement rather than an operating habit.

Looking at what arrives and what leaves

Two inspection duties bracket the warehouse, one inbound and one outbound.

On receipt, each outside shipping container is visually examined for identity and to prevent the acceptance of contaminated drugs or drugs otherwise unfit for distribution. The examination has to be adequate to reveal container damage that would suggest possible contamination or other damage to the contents.

Each outgoing shipment is carefully inspected for identity of the products, and to ensure that no drugs damaged in storage or held under improper conditions are delivered.

Returns get the strictest sentence in the part. Where the conditions of a return cast doubt on a drug's safety, identity, strength, quality or purity, the default is destruction or return to the supplier. It is displaced only where examination, testing or other investigation proves the drug meets appropriate standards.

A separate rule covers containers that have been opened at all. Any prescription drug whose immediate, sealed outer or sealed secondary container has been opened or used is identified as such, and quarantined and physically separated until it is destroyed or returned.

The rule then says what to weigh in making that judgment. Two things are named among others. The conditions under which the drug was held, stored or shipped before or during its return. And the condition of the drug and its container, carton or labeling as a result of that storage or shipping.

The records, and the clock on producing them

Inventories and records of all transactions regarding receipt and distribution or other disposition have to be established and maintained.

Three fields are named. The source of the drugs, including the name and principal address of the seller or transferor and the address of the location from which they were shipped. The identity and quantity of the drugs received and distributed or disposed of. And the dates of receipt and distribution or other disposition.

They are kept for three years after creation, and made available for inspection and photocopying by authorized federal, state or local law enforcement officials.

Availability has a deadline attached. Records kept at the inspection site, or immediately retrievable by computer or other electronic means, have to be readily available during the retention period. Records kept at a central location and not electronically retrievable have to be made available within two working days of a request.

Written policies and procedures sit on top of that. They cover receipt, security, storage, inventory and distribution, and they include four named procedures. One distributes the oldest approved stock first. One handles recalls and withdrawals. One prepares for a strike, fire, flood or other emergency. And one segregates and disposes of outdated drugs, with written documentation of the disposition kept for two years.

Two more duties close the section. A distributor maintains a list of the officers, directors, managers and other people in charge of distribution, storage and handling, with their duties and a summary of their qualifications. And it permits the licensing authority and law enforcement officials to enter and inspect its premises and delivery vehicles, and to audit its records and written procedures, at reasonable times and in a reasonable manner.
