neonate | up to 1 month after birth |
infant | 1 mon to 2 years |
child | 2 - 12 years |
adolescent | 13 - 19 years |
adult | 20 - 70 years |
elder | older than 70 years |
pharmacogenomics | a field of study that defines the hereditary basis of individual differences in absorption, distribution, metabolism, and excretion (the ADME processes) |
acute viral hepatitis | an inflammatory condition of the liver caused by viruses |
cirrhosis | a chronic liver disease causing loss of function |
hyperthyroidism | a condition in which thyroid hormone secretions are above normal, often referred to as an overactive thyroid. |
hypothyroidism | a condition in which thyroid hormone secretions are below normal, often referred to as an underactive thyroid. |
obstructive jaundice | an obstruction of the bile duct that caused hepatic waste products and bile to accumulate in the liver |
adverse drug reaction | an unintended side effect of a medcation that is negative or in some way injurious to a patient's health. |
anaphylactic shock | a potentially fatal hypersensitivity reaction producing severe respiratory distress and cardiovascular collapse. |
carcinogenicity | the ability of a substance to cause cancer. |
hypersensitivity | an abnormal sensitivity generally resuting in an alleric reaction. |
idiosyncrasy | an unexpected reaction the first time a drug is taken, generally due to genetic causes. |
complexation | when two different molecules associate or attach to each other. |
displacement | a drug that is bound to a plama proten is removed when another drug of greater binding potential binds to the same protein |
enzyme induction | the increase in hepatic enzyme activity that results in greater metabolism of drugs. |
enzyme inhibition | the decrease in hepatic enzyme activity that results in reduced metabolism of drugs. |
additive effects | the summation in effect when two drugs w/ similar pharmacological actions are taken. |
antidote | a drug that antagonizes the toxic effect of another |
potentiation | when one drug w/ no inherent activity of its own increases the activity of another drug that produces an effect. |
synergism | when 2 drugs w/ similar pharmacological actions produce greater effects than the sum o individual effects.actions |
drug-drug interactions | do not alter the drugs' disposition but interact at the site of action. |
drug-diet interactions | when elements of ingested nutrients interact w/ a drug and this affects the disposition of the drug. |
