What is a drug?

General definition

Classes of drugs

Where a class of drug is used to refer to a specific treatment, it will be annotated. For example,

Where a drug class is mentioned, and later individual drugs that are members of that class are also mentioned, you should be careful not to co-refer the class of drug with the individual drugs. See the guideline on Co-reference

"Treatment" and general words for drugs

The definite use of general words that clearly co-refer back to an earlier mentioned drug, will be annotated and co-referred.

What is not a drug?

Drugs in headings

General references to "drugs", e.g. in headings, will not be annotated. For example, in:

Drugs as modifiers of conditions

Where a drug or class of drug is used as a modifier, it will not be annotated. For example,

Dosage and route

It is not neccesary to annotate either the dosage or the route of administration: just the drug itself.

Body substances

The patients's own body substances should not be annotated as drugs or devices.

Chemotherapy

The word "chemotherapy"

Where the word "chemotherapy" is used to refer to a specific treatment using some broad class of drugs, it will be annotated. For example,

Individual chemotherapy drugs

Where a specific drug is mentioned as part of chemotherapy, it should be annotated. For example,

Protocol names

Please do not annotate specific chemotherapy trial names and protocols as drugs: we do not want to collect them.

Co-reference

Co-reference that requires a knowledge of pharmaceuticals will be annotated. For example, in:

Devices

A device is some manufactured object or substance used in the treatment or investigation of a patient. For example,

Medical devices will be annotated as drugs / devices.
