The flashcards below were created by user tsbatiste on FreezingBlue Flashcards. What would you like to do?


  1. Name the routes of administration and their bioavailability value
    • IV - 1
    • IM - 0.85
    • SQ - 0.75
    • PO - 0.45-0.56
    • IP - 0.45
    • Per rectum - 0.21
  2. This is the movement of drug molecules from an area of high concentration to an area of low concentration across a semi-permeable membrane:
    Passive Diffusion
  3. Does passive diffusion require energy?
    No
  4. This is the movement of drug molecules being surrounded by a carrier molecule within the cell membrane and carried into the cell usually from an area of high concentration to an area of low concentration:
    Facilitated Diffusion
  5. Does facilitated diffusion require energy?
    yes
  6. This is the movement of drug molecules that are surrounded by carrier molecules within the cell membrane and carried into the cell against the concentration gradient:
    Active Transport
  7. Does active transport require energy?
    Yes
  8. This is where the drug molecules particularly large proteins and intact antibiotics are surrounded and/or engulfed by the cell's membrane and taken within the cell
    Pino/phagocytosis
  9. Do pino/phagocytosis require energy?
    Yes
  10. This is the movement of drug molecules from systemic circulation into tissues
    distribution
  11. This is the degree to which an administered drugs is absorbed.
    bioavailability
  12. This is the breaking up of a drug into smaller particles to be absorbed
    dissolution
  13. What form of drugs does not have a dissolution phase?
    liquid forms
  14. Describe ion trapping:
    A drug in lipophilic form penetrates the cell membrane and enters the cell.  The pH within the cell causes a dramatic shift to the hydrophilic form and the drug can no longer passively diffuse out of the cell.  However since there is a set ratio of hydrophilic to lipophilic molecules any lipophilic molecules will diffuse out of the cell causing other hydrophilic molecules to convert to lipophilic to maintain that set ratio.  Eventually this allows the drug to pass into systemic circulatiion.
  15. What are SR tablets and why aren't they used much in small animal medicine?
    Sustained Release tables are designed to dissolve slowly to allow small amounts of drug to be released into the system over a long period of time.  Since the digestive tract of canine and feline patients is much shorter than humans, the drug will not have enough time to dissolve and be absorbed
  16. Describe the first pass effect:
    Once a drug is absorbed into systemic circulation it goes to the liver via the hepatic portal system.  The liver assumes the drug is a foreign substance or xenobiotic and removes a substantial amount before allowing the remainder to reenter general circulation.
  17. This is an drug completely dissolved in a sweetened alcohol base that is only administered orally.
    Elixir
  18. An example of an elixir would be:

  42. Describe the MFO system:
    Mixed Function Oxidase system is the most common group of enzymes in biotransformation phase 1. Repeatedly used drugs cause an increase in the number of enzymes available.  This increases the rate at which these drugs are metabolized, thus causing induced metabolism
  43. Describe Biotransformation Phase I.
    After the drug exerts its effect and decomposes, it is returned back to the liver where it is either oxidized, reduced or hydrolized  by the MFO system to a generally less active metabolite
  44. Describe Biotransformation Phase II

    • Zona fasciculata: glucocorticoids (cortisone)
    • Zona reticularis: sex hormones (5%) and some glucocorticoids
  245. Name the enzyme that produces thromboxanes and prostaglandins
    cyclooxygenase
  246. Give 2 names which thromboxanes, prostaglandins and leukotrienes are collectively called.
    Eicosanoids or Autocoids
  247. This means low numbers of eosinophils and is a part of the "stress triad"
    eosinopenia
  248. This is the term for the production of glycogen in the liver
    glycogenesis
  249. This is the hormone produced in the hypothalamus that stimulates the anterior pituitary gland to release ACTH
    Corticotropin releasing factor
  250. This means decrease monocytes
    monocytopenia
  251. This means "decreased size": seen with muscles and skin in animals with exogenous corticosteroids
    atrophy
  252. This means a condition or disease "cause by the veterinarian"
    Iatrogenic
  253. This is the enzyme that produces leukotrienes
    Lipooxygenase
  254. This group of adrenocorticosteroids affects mainly the electrolytes and water balance in the body
    mineralocorticoids
  255. This is the creation of glucose from animo acids produced from protein catabolism
    Gluconeogenesis
  256. The means a "decrease of lymphocytes in circulation" and is part of the stress triad
    lymphopenia
  257. This is the chemical structure of a group that includes ibuprofen, naproxen and ketoprofen
    Propionic acid
  258. This is the series of enzymes that result in the production of eicosanoids(autocoids) after an injury
    Arachadonic acid pathway (vane model)
  259. This hormone release by the anterior pituitary gland stimulates the production of glucocorticoids in the zonal fasciculata
    Adrenocorticotropic hormone
  260. This is the dual-pathway NSAID because it blocks both COX and LOX
    Tepoxalin (Zubrin)
  261. This chondroprotective agent is a component of synovial fluid that acts as a  lubricant, increases viscosity of the fluid
    Hyaluronic acid
  262. This is an intermediate acting corticosteroid that is not a "pred"
    Triamcinolone acetate
  263. PSGAGs
    Polysulfated glycoaminoglycans
  264. These effects are associated with corticosteroids
    • Maintain capillary integrity
    • Decreased fibroblast activity
    • Decreased T-lymphocyte activity
    • Decreased scar tissue formation
    • Increased neutrophils
    • Muscle wasting and atrophy
  265. These two nutriceutical chondroprotective agents are precursors for PSGAGs
    glucosamine and chondriton sulfate
