How does NICE decide whether a licensed medicine is used in the NHS?

NICE judges whether a licensed medicine is cost-effective compared with existing treatments. NICE guidance is reviewed by the Department of Health before it applies in Northern Ireland.

Who must approve a clinical trial before it starts in the UK?

The MHRA must authorise a trial of a medicine, and a research ethics committee must give a favourable opinion. The ethics committee checks that risks are justified and consent procedures are adequate.

What are the responsibilities of a pharmaceutical manufacturer?

A manufacturer must make medicines to Good Manufacturing Practice standards and test every batch for purity and strength. The manufacturer must also label products accurately and report suspected side effects to the regulator.

Questions from this subtopic

Each one with the model answer underneath.

1
What must a company provide before a new medicine is licensed in the UK?
Model answer
The company submits evidence of the medicine's quality, safety and effectiveness from laboratory, animal and clinical studies. The regulator assesses the evidence before granting a marketing authorisation.
2
What is the role of the Medicines and Healthcare products Regulatory Agency?
Model answer
The MHRA regulates medicines and medical devices in the UK. The MHRA licenses medicines, authorises clinical trials, inspects manufacturers and monitors safety after launch.
3
What is the role of the Commission on Human Medicines?
Model answer
The Commission on Human Medicines is an independent committee of experts. The commission advises government and the MHRA on the safety, quality and effectiveness of medicines.
4
How does NICE decide whether a licensed medicine is used in the NHS?
