Different occupational exposure limits require different safety measures to handle APIs. DOTTIKON's experience ensures a safe handling of all processes involved.

To handle active substances, DOTTIKON has state-of-the-art containment concepts on all scales (e.g. closed charging / handling / discharging, full protection suit, monitoring, WIP/CIP cleaning, and cleaning validation). These concepts are applied by highly skilled and regularly trained staff.

Quality Management

cGMP and other higher industry quality standards are an integral part of the comprehensive quality system of DOTTIKON's independent Quality Management department.

DOTTIKON meets the high quality requirements of its customers thanks to the strict adherence to a quality system based on the process approach of ISO 9001:2015, which includes cGMP according to ICH Q7 as well as safety, health and environmental (SHE) protection.

DOTTIKON is authorized by Swissmedic (Swiss Agency for Therapeutic Products) to manufacture and sell active pharmaceutical ingredients (APIs) including liquid and solid dosage forms. It is subject to regular inspections by the Regional Medicines Inspectorate of North-Western Switzerland. The most recent audit was completed in February 2022.

The Quality Management system is based on a 3-level hierarchy

  1. Quality manual with a general overview and the perspectives of quality management
  2. Processes and general instructions for the main business processes
  3. Standard operating procedures with detailed description of each operational step

As part of the company's Quality Management, the Quality Control unit is responsible for testing raw materials, intermediates and final products to ensure compliance with specifications. The process analytics unit is responsible for in-process tests as well as release of cleaning results. The Quality Assurance unit monitors compliance with cGMP requirements such as review of batch records. Activities such as cleaning and process validation are performed by the responsible Quality Management project manager.

Active Substance Master Files (ASMF) or Drug Master Files (DMF) are prepared in the new eCTD format and are registered with the respective authorities worldwide

  • In Europe with the EMA (European Medicines Agency) in the 'centralized procedure' and with the several national authorities in the 'national procedure'
  • In USA with FDA as Drug Master File Type II
  • In Japan with PMDA (Pharmaceutical and Medical Devices Agency)
  • In several other countries such as Australia, New Zealand and Canada

DOTTIKON's most recent FDA inspection was completed in December 2022.

Recycling & Waste Treatment

Recycling & Waste Treatment includes recycling, thermal recovery, and high-temperature incineration of waste streams, as well as waste water treatment and purification.

The high-temperature waste processing plant is one of the most modern incineration plants in the world.
It was built to incinerate waste that cannot be treated in any other type of plant

  • Incineration of 8'000 to 9'000 tons of waste per year (solid, liquid, and gaseous waste)
  • Continuous plant operation (24 hours per day, 7 days per week)
  • Computer-assisted operation and control of all process parameters

The on-site waste water pre-treatment plant consists of activated carbon adsorption of organic impurities, followed by neutralization and sedimentation. The used carbon is reactivated for reuse.

Based on the quality management system according to ISO 9001:2015, DOTTIKON ensures that the safety, health and environmental requirements of authorities and customers are consistently met.
