Pharmacology is the science of drugs and their effect on living systems. You can find pharmacology present everywhere. In medicine cabinets, when you visit the dentists and when you take any type of medication. Pharmacology is also responsible for painkillers, caffeine drinks and antibiotics. It is the science of what is happening to your body and to the drug itself.
Pharmacology is crucial for: discovering new medicines to help fight diseases, improving the effectiveness of medicines, reducing unwanted side effects of medicines and understanding why individuals differ in the way they respond to certain drugs, and why some others cause addiction.
Pharmacology lies at the heart of biomedical science, linking together chemistry, physiology and pathology. Pharmacologists work closely with a wide variety of other disciplines that make up modern biomedical science, including neuroscience, molecular and cell biology, immunology and cancer biology.
