About Z-Index
Z-Index maintains and updates the G-Standaard, the official Dutch drug database used by all healthcare stakeholders in the Netherlands. The G-Standaard contains comprehensive information on all products dispensed by or used in pharmacies, facilitating efficient and accurate data exchange across the healthcare system.
The Dutch Drug Database: G-Standaard
The G-Standaard provides detailed information on:
- Licensed medicines
 - Unlicensed medicines (e.g. raw materials and compounded preparations)
 - Vitamins and dietary supplements
 - Homeopathic medicines
 - Medical devices
 
Over 100,000 healthcare products are registered in the G-Standaard. Each product entry includes essential information such as pharmacovigilance data, pricing, logistics, and reimbursement policies of various health insurers.
Healthcare professionals use the G-Standaard in a variety of ways:
- Physicians consult the G-Standaard to find available medicines and prescribe accurate dosages.
 - Pharmacists use it to check for potential drug interactions (pharmacovigilance) and verify insurance reimbursements. It also supports direct invoicing to insurers.
 - 
Pharmacists, wholesalers, and manufacturers rely on the database to place orders and manage inventory.
 
Z-Index’s Role in the G-Standaard
 
Z-Index acts as a trusted intermediary, ensuring that the data in the G-Standaard is accurate, up to date, and accessible through software vendors. To maintain data quality, Z-Index works closely with manufacturers, wholesalers, scientific institutions, regulatory bodies, and the government, both as data providers and end users.
Pharmacotherapeutic information in the G-Standaard is supplied by the Medicines Information Centre (Geneesmiddel Informatie Centrum) of the Royal Dutch Pharmacists Association (KNMP).
G-Standaard Data Entry Portal for Manufacturers
The G-Standaard Data Entry Portal allows registered manufacturers to submit new healthcare products or update existing ones. Updated information is distributed via the G-Standaard’s monthly production cycle, ensuring it reaches all relevant prescribing, dispensing, and ordering systems in the Dutch healthcare market.
More details can be found in the Instruction Manual.
Z-Index adheres to a strict monthly production schedule to guarantee timely integration of updates. Software vendors use these updates to ensure healthcare IT systems - used by pharmacies, general practitioners, hospitals, and insurers - are always current. This process relies on all data providers, including over 700 manufacturers, to follow the production schedule closely.
