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.
Pharmacokinetics is the study of what the body does to the drug, including
absorption, distribution, metabolism, and excretion/ Absorption, distribution,
metabolism, excretion.
Pharmacodynamics is the study of what the drug does to the body/ Drugreceptor interaction.
- The drug naltrexone is given to prevent relapse or cravings in individuals who

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

Antacids (Gaviscon) Neutralize gastric acid - Carl 57-year-old male, has come to the clinic today for a standard wellness
visit. The nurse asks Carl, what, if any, medications he is taking? He lists a
medication typically associated with arthritis. The nurse has had many patients

the nurse discuss with Carl pertaining to supplementation use and reporting
whether he takes them?
He should disclose this, and know supplements are not safe via being natural. As
dietary and herbal products can cause adverse effects, toxic effects, and allergic
reactions just like prescription and OTC medications. And can also have drug
interactions with other medications causing unwanted side effects. - Which treatment for chronic heart failure works by decreasing blood volume,
