2. What is a clinical trial?

 

Clinical trials are studies to see how well medicines or treatments work when they are used to treat different types of illness and conditions.

 

These studies give us important information about how well the medicine works and if there are any side-effects.

 

Medicine can be tablets, liquids, creams or injections to treat eczema (dry-skin), asthma (wheeze), infections (colds and viruses) or other sicknesses. 

 

We sometimes want to know how well medical devices such as plasters, dressings, thermometers or breathing masks work on children.
