1.
Sublingual: When rapid effect is needed right away
Subcutaneous: Destroy or inactivated in the GI Tract
PR
Intramuscular: Used for drugs with poor oral absorption
Topical: For local effects on skin and eyes
O
Pharmaceutics is the study of how various dosage forms influence the way in
which the drug affects the body/ Administration of dosage form, dissolution of
drug into body/ manipulating chemical compound.
FD
Pharmacokinetics is the study of what the body does to the drug, including
absorption, distribution, metabolism, and excretion/ Absorption, distribution,
metabolism, excretion.
O
Pharmacodynamics is the study of what the drug does to the body/ Drug-
receptor interaction.
C
2. The drug naltrexone is given to prevent relapse or cravings in individuals who
use opioids. It binds to opioid receptors blocking endogenous agonist and other
opioid drugs from binding and having an effect. Naltrexone is a/an
Competitive agonist (binds to the same site of agonist)
3. Due to the many chronic diseases associated with aging the elderly can have
decreased blood flow to the liver. With age, there can also be a decrease in liver
enzymes, which can increase the duration of a drug in the patient’s systems.
Which pharmacokinetic process is affected in this scenario?
Metabolism (stored in the body)/ cytochrome P-450 enzymes/ liver/ Grapefruit
and statins
