Medicines Australia, on behalf of the Australian medicines industry, has donated $100,000 in cash to the Premier's Flood Relief Appeal to support those devastated by the floods in Queensland.

Chief executive Brendan Shaw extended his deepest sympathy, on behalf of the industry, to the victims of the floods.

"This has been a truly awful experience for anyone affected by these horrific floods," Dr Shaw said.

"Our thoughts and sympathy go out to all who are suffering in the face of this devastating tragedy, particularly those who have lost friends or family members."

Individual Medicines Australia member companies are making additional contributions to the disaster relief.

The organization also said it has offered the Department of Health and Ageing any assistance that may be required to ensure the supply of medicines to flood-stricken areas is maintained.

Medicines Australia represents the Australian medicines industry. Its member companies comprise more than 80 per cent of the prescription pharmaceuticals market, and are engaged in the research, development, manufacture, supply and export of prescription medicines.
