A set of extended ATC codes are being presented here in order to code both more specific on subtypes of the drugs, e.g. saquinavir hard and soft gel, but also to enable coding of drugs that are at their trial stage and have not yet been assigned an ATC code. To do this the drug will be assigned the code elements as far down the levels as possible. Given two examples to illustrate this:

Saquinavir - Hard Gel

J05AE01-SQH

Saquinavir - Soft Gel

J05AE01-SQS

Saquinavir - not specified

J05AE01

This will ensure the fidelity needed to distinguish between hard and soft gel and not specified, but also for analysis easily include all records which coding starts with J05AE01, regardless if the drug is hard or soft gel.

See the ​ATC Index for the individual codes. The extended ATC codes are listed below along with a subset of ATC codes relevant to ART.
