Uses of drugs (6)

- Therapeutic uses (for the treatment of diseases) [e.g. ibuprofen, fluoxetine]
- Experimental tools in biomedical research aimed at understanding physiological processes as well as elucidating the underlying causes of diseases in an effort to improve treatment. (to study the function of a cell or protein]. (e.g. PYR1, Phalloidin)
- Non-medical purposes -drugs that are used in the past for therapeutic purposes but are also used widely abused for non-medical purposes (e.g. amphetamines, cocaine and morphine)

11

Similarities of pharmacology and toxicology

both look at drugs

Pharmacology

a branch of science concerned with the study of drugs and medicines. This includes their discovery, development/manufacture, effects, side effects and fate in the body, as well as uses. The study of drugs and their interactions with living systems.

13

Pharmacology comes from the Ancient Greek word...

pharmakon

14

Pharmacy

discipline that is concerned with the preparation and dispersing of drugs

15

Divisions of pharmacology

- pharmacokinetics
- pharmacodynamics
- therapeutics

16

Pharmacokinetics

the study of the fate of drugs and medicines in the body (what does the body do to drugs, how is it taken, how does the body clear it)

17

Pharmacodynamics

the study of the actions of drugs and medicines in the body (what do drugs and medicines do in the body and how do they achieve their effects in the body) [where it acts, what the effects are]

18

Therapeutics

the use of drugs and medicines in the treatment of diseases
