Moreover, the laboratories branch also contributes to post-market monitoring and the evaluation of a range of therapeutic products for market authorisation of drug.
  • Manufacturing quality branch guarantees that manufacturers engaged in the production of medicines, along with tissue, blood, and cellular therapies, meet the required quality standards.

What is the role of the TGA?

The TGA monitors the ongoing benefits and risks of therapeutic goods once they are authorised for application. Moreover, the agency can take any action if the benefits are not realised, or additional risks become noticeable.

The probable regulatory measures are distinct from minimal intervention, like labelling modifications, to withdrawing the therapeutic good from the market.

The TGA manages an overall control via the following main processes-

  • Pre-market evaluation as well as approval of registered products aimed for distribution in Australia.
  • Development, maintenance, and monitoring of the system for registering any new therapeutic product.
  • Licencing of producers in agreement with global standards of the good manufacturing practices (GMPs).
  • Post-marketing monitoring via sampling, reporting of adverse events, surveillance activities as well as response to public enquiries.
  • Assessment/review of medicine for its import and export.

Risk management approach of the TGA to regulate therapeutic goods

The Therapeutic Goods Administration is responsible for making sure that the therapeutic goods accessible for supply in Australia are safe and appropriate for their expected objective. These include therapeutic goods Australians depend on every day, like sunscreens & vitamins through to medicines to treat severe diseases including prescription medicines, surgical implants, vaccines, and blood products.

In quintessence, this means that the agency-

  • Identifies, reviews, and assesses the risks caused by any therapeutic goods.
  • Applies any necessary measures for treating the risks caused by a therapeutic good.
  • Monitors and analyses the risks over time.

Therapeutic goods are not free of risks completely, and the associated risks could be mild, moderate, or severe. The function of the agency is based on applying scientific along with some clinical expertise to make any decision. By this way, the agency ensures that the benefits to users outweigh any risks associated with the use of a specific therapeutic product, medical devices, or any other medicine.

For instance, some blood pressure medications might have some side effects, such as persistent cough or throat tickle. However, the associated risks by blood pressure medicine are outweighed by the advantages of lowering the chances of a stroke or heart attack. Moreover, the risk-benefit approach ensures that the medicine or products the users take are safe for their intended purpose, while still giving access to products that play an essential role in health needs.

The Therapeutic Goods Administration works closely with consumers, health professionals, industry along with international counterpart to ensure the safety of any therapeutic product or medicine.
