Describe the terms: Potency
Refers to the required amount of a chemical for a given effect.
Describe the terms: Selectivity
The narrowness of a drugs range of actions on particular receptors, cellular processes or tissues.
Describe the terms: Specificity
The relation between the chemical structure of a drug and its pharmacological actions within the body.
Below are some of the pharmacologically active compounds found in plants, Give a brief description of each and name at least one example Alkaloids
Organic nitrogen containing compounds;; Examples include codeine, Morphine & Nicotine
Carbohydrates
Organic compounds Carbon, Hydrogen and Oxygen;; Examples include Starch, sugars & fibres
Glycosides
Carbohydrates that yield a sugar and non-sugar on hydrolysis; Examples include Digoxin

Glycosides | Carbohydrates that yield a sugar and non-sugar on hydrolysis; Examples include Digoxin |
Hydrocarbons | Used as a base for most drugs especially topical ointments; Examples include castor oil & waxes |

Steroids | Compounds that contain four cycloalkane rings together; Examples include cholesterol, androgens and progesterone |
Oils | Highly viscous liquids there are two kinds of oils; Fixed- leaves greasy stains eg Castor oil/Olive oil; Volatile- Does not as it evaporates eg Eucalyptis peppermint |
Define the following in relation to Drug names and classifications Chemical names | Official name of the drug(not used by the general public); Describes the drugs chemical composition and molecular structure. |
Generic names | The agreed name of each drug that has been approved by the local drug authority
What us nurses look up in MIMS |
Trade names | The particular brand of each drug eg Paracetamol would come under Panadol, Febridol etc |
List the categories into which drugs can by classified | There are several categories but the main three are; Clinical indication, By body system and by mechanism of action |

In 2003, the Australian Health Minister’s Advisory Council established categories for ranking of the abuse potential of various drugs and management of poisons in the Uniform Scheduling of Drugs and Poisons. Below describe the different schedules of drugs and list two examples of drugs within this category if applicable. Schedule 1 | Technically not in use but covers natural/herbal remidies |
Schedule 2 | Pharmacy Medicine; Examples Include Paracetamol & Nurofen |
Schedule 3 | Pharmacy Only Medications; Examples Include Codeine & Pseudoephedrine |
Schedule 4 | Prescription Only Medications; Examples Include |
Schedule 5 | Poisons(Caution); Examples Include Methylated spirits & Kerosene |
Schedule 6 | Poisons(Dangerous); Examples Include Alkaline Salts & Eucalyptus Oil |
Schedule 7 | Poisons(Extreme); Examples Include Aresenice, Cyanide & Thallium |
Schedule 8 | Controlled Drugs; Examples Include Morphine, Oxycodone & Fentanyl |
Schedule 9 | Prohibited Substances; Examples Include Cocaine, Heroine & Ecstasy |
