❖ Antagonists – drugs that block a response
❖ Therapeutic index – the level of the drug between the minimum effective level and the
minimum toxic level
❖ Trough level – minimum effective level (plasma drug levels are the lowest)
❖ Loading dose – to achieve a rapid minimum effective concentration in plasma (after loading
dose is given daily dose is provided)
❖ Peak level – minimum toxic level (plasma drug level is the highest)
□ If either the peak is too low or the trough is too high, toxicity can occur
□ Most often used for antibiotics
❖ Characteristics to consider
□ Effectiveness – if not effective it should not be used
□ Safety – No drug is safe (Does the good outweigh the bad)
□ Selectiveness – No such thing as a wholly selective drug
