diagnostic uses
thallium for exercise stress tests to show uptake into active/normal muscle
radiopaque contrast agents used in certain x ray procedures like IVP
Natural source drugs (derived from plants)
digitalis (Lanoxin), scopolamine, atropine, ephedrine, galantamine (Reminyl), aspirin
digitalis
Lanoxin: very narrow therapeutic window. Derived from foxglove plant and used to increase heart contraction strength
scopolamine; atropine
from belladonna plant and used by women to dilate eyes originally
ephedrine
from ephedra species and used as bronchodilator and decongestant
galantamine
Reminyl: isolated from daffodil bulbs but only barely treats early Alzheimer’s
Natural source drugs (derived from animal sources)
thryoid hormone, estrogen (Premarin), insulin
thyroid hormone
derived from various animals for HRT
estrogen
Premarin: from pregnant mare urine. Used originally to treat hot flashes in women that were post-menopausal
insulin
used from cows and pigs originally until recombinant DNA technology could be applied so bacteria could make it
Natural source drugs (from mineral sources)
potassium, lithium, iron, calcium, technetium, thallium, barium (last three used for radiology)
dangers of using drugs from natural sources versus synthetic
melatonin from animal sources may contain prions, for example, while synthetic never would
