Document Summary
Two types of drug market, prescription drugs and over the counter drugs. Important things to consider: safety, counter indications. Dose makes the drug (recommended dose = good; too much = bad) Find out what effect is and how often it happens (need both to evaluate risk) Counter indications: when should you not use drug? (i. e. conditions -> don"t take drug with heart condition, drug combinations (drugs react with each other, foods, natural remedies. Aspirin most popular comes from salix/willow tree. Willow bark first used to cure fever/sacilin was extracted from willow powder. Need 1. 5kg of willow bark to get 30g of sacilin (doesn"t provide enough) Sacilin can be broken down into salicylic acid (provides same effect with less needed for effect) Sacilicylic acid could be taken from coal tar (coal tar also used as cloth dye) Natural: take drugs from stuff in nature. Synthetic: product made from petroleum or oil.
