Longer half life= less frequent doses
CAUTION WITH PTS WITH LIVER AND OR KIDNEY DISEASE- Takes linger to get rid
of drugs
Pharmaceutic Phase
Dissolution of the drug

Enters systemic circulation
Exposes body tissue to effects of drug
, Certain drugs may have affinity for certain organs or tissues

Antagonist
Blocks drug; Join with receptors to prevent action of agonist; Narcan blocks effects of
morphine overdose
Adverse drug reactions
undesirable drug effects
