QUESTIONS AND 100% CORRECT

ANSWERS|2025/2026

Pharmacotherapeutics - ANSWER-Using drugs to treat, care, relieve, prevent, or diagnose diseases

Pharmacokinetics - ANSWER-How body effects drugs metabolism and action:

Absorption, duration of action and effect, distribution in the body, method of excretion

Pharmacodynamics - ANSWER-How drugs and their actions affect the body at cellular level

Drugs can have four different names - ANSWER-Chemical Generic Official Brand, trade, or proprietary

Chemical name - ANSWER-Describes its chemical make up, describes atomic or molecular makeup

Generic name - ANSWER-Given by the developer, often same as chemical name, before a job becomes officially an approved medication, IDs active ingredient

Official name - ANSWER-Name listed in the US pharmacopeia (USP) We can see if they have gone through all the processes if they are listed in this manual Sometimes the same as generic name

Blood flow to area of absorption Body surface area Lipid solubility of a medication G.I. hypermotility Drug molecule size

Route of administration - ANSWER-Drugs may have more than one Different areas absorb differently

Ability to dissolve - ANSWER-Form Drugs acidity or alkalinity

Blood flow to area of absorption - ANSWER-Large amount of blood vessels absorbs quickly Few blood vessels like in fatty tissue absorbs slower

Body surface area - ANSWER-Faster in contact with large surface areas Drug in contact with body tissues Intestines large surface area

Lipid solubility of a medication - ANSWER-High fat, or lipid Not in vascular compartment long Food plays a role Medication's that have a high fat or lipid content absorb more easily and cross cell membranes faster than those to have less

GI hypermotility - ANSWER-May not be absorbed because of being pushed through the body too quickly (vomiting, etc)
