Drugs and the Brain outlines the important types of drugs, including anaesthetics, antipsychotics and antidepressants, which are used to influence activity in the brain. You will learn how these drugs act on neurotransmitters and the side effects that their actions can cause.


Unit title Unit code Requirement type Description

Clinical Drug Development BIOL21302 Co-Requisite Recommended
BIOL21312 Pre & Co-requisites are BIOL10822


To describe

  • the aetiology and symptomology of a range of brain disorders
  • the range of mechanisms by which drugs can interfere with neurotransmission in the central nervous system (CNS)
  • how neurotransmitter activities can be modified by drugs leading to the rational treatment of CNS disorders
  • how an understanding of neurotransmitters and mechanisms of drug action can lead to more selective treatment of CNS disorders.

Learning outcomes

After completing the unit and recommended reading, students should have an understanding of:

  • basic mechanisms of brain disorders
  •    important classes of drugs used in medicine and/or biological research to influence central neuronal activity, particularly in humans
  •    the mechanisms of action of these drugs in terms of their effects on major neurotransmitters
  •    mechanism-related drug side-effects


  •     Introduction to neuropharmacology
  •  The central synapse: neurotransmitter systems as targets for drug therapy
  •  Accessing the central synapse: the blood-brain barrier to drugs
  •  Pharmacology of movement disorders such as Parkinson’s disease
  •  Pharmacology of general anaesthetics and local anaesthetics
  •  Pharmacology of antipyretic-analgesic drugs
  •  Pharmacology of opioid analgesic drugs
  •  Pharmacology of antiepileptic drugs
  •  Pharmacology of anxiolytic drugs
