Q

Addison’s disease is treated with which drugs?

A

Fludrocortisone has both a mineralcorticoid (aldeosterone) and glucocorticoid (cortisol) activity. Desoxycorticosterone must be used with a glucocorticoid (prednisone) because it only has mineralocorticoid (aldosterone) activity.

21
Q

A

Diuretics- useful for edema, CHF, some diseases of kidneys/liver/GI tract

Student #11 SF
McCurnin 9th ed.
pg 967

22
Q

What is the most common side effect of most antibiotics? What may be recommended in order to prevent this side effect?

A

GI upset (vomiting/diarrhea)

May recommend giving antibiotics with food to prevent GI upset

Student #11, SF
McCurnin 9th ed.
pg.960-962

23
Q

Why is it important to consider adjusting dosages for patients with kidney disease/failure?

A

The kidneys play a major role in drug excretion, so if they are diseased or failing, there will be less excretion and a higher blood concentration of drugs. This leads to higher risk for adverse reactions and/or toxicity, especially for drugs that are primarily excreted in the kidneys (fluoroquinolones, aminoglycosides, enalapril, digoxin, chloramphenicol)

Student #11 SF
McCurnin 9th ed. pg9 958

24
Q

Why is it contraindicated to use NSAIDs and steroids (glucocorticoids) concurrently?

A

Both of these anti-inflammatory drugs can cause GI ulceration, so using them together poses greater risk for severe GI ulceration and/or perforation.

Student #11 SF
McCurnin 9th ed.
pg. 972

25
Q

How are immunosuppressive drugs typically used for long-term management of immune-mediated diseases? WHy?

A

Initially, immunosuppressives will be given at higher doses to control the symptoms and stabilize the underlying disease. Then, the patient will gradually be tapered off of the drugs to the lowest possible therapeutic dose. This is done to minimize the adverse effects of long-term immunosuppressive use.

Student #11 SF
McCurnin 9th ed.
pg. 972

26
Q

What is the mechanism of action for diuretics?

A

Diuretics inhibit the reabsorption of sodium at different parts of the nephron or collecting duct.

Student #10 MS
McCurnin 10th ed.
pg. 889

27
Q

Treatment of heart disease can include the use of what drugs?

A

Diuretics to reduce fluid accumulation. Inotropic agents to improve contractility of cardiac muscles. Antihypertensives to modulate blood pressure. Antiarrhythmics to control heart rhythm abnormalities.

Student #10 MS
McCurnin 10th ed.
pg. 889

28
Q

What are the side effects of long term Glucocorticoid use?

A

Long term Glucocorticoid use can cause immunosuppression, delayed wound healing, polyuria, polydipsia, and diabetes mellitus.

Student #10 MS
McCurnin 10th ed.
pg. 894

29
Q

What are the risks for each schedule of controlled drugs?

A

Schedule I: Use not accepted in a practical setting in the US.
Schedule II: Risk of sever psychic or physical dependence in humans.
Schedule III: Risk of moderate to low physical dependence but high psychological dependence.
Schedule IV: Risk of limited physical or psychological dependence in humans.
Schedule V: No DEA limit on prescriptions.

Student #10 MS
McCurnin 10th ed.
pg. 878

30
Q

How does an animal’s metabolism eliminate drugs?

A

Enzyme systems in the GI tract, kidney, and liver inactivate drugs and/or make them more water soluble for elimination in urine or bile.

Student #10 MS
McCurnin 10th ed.
pg. 880

31
Q

What is the first-pass effect?

A

When a portion of a drug is lost during the process of absorption in the liver. Large amounts of a drug delivered PO will be metabolized before even entering the bloodstream.

CP Student #9 McCurnin 9th ed. #956

32
Q

Why is it important to consider doses of highly protein-bound drugs in patients with hypoproteinemia?

A

A portion of the drug binds to albumin and creates a larger molecule that cannot move out into tissues. Only the unbound portion of the drug is distributed and causes the desired effects. If a patient has hypoproteinemia, they have less protein available to bind to the drug. This causes a higher portion of the drug to be distributed to tissues, making adverse side effects or overdose more likely.

CP Student #9 McCurnin 9th ed. #956

33
Q

Why is the most common side effect of antibiotics vomiting and diarrhea?

A

Antibiotics can affect the normal bacterial flora in the GI tract, creating a bacterial imbalance. Specific antibiotics also directly irritate the stomach.

CP Student #9 McCurnin 9th ed. #962

34
Q

Why should long-acting glucocorticoids be avoided when possible?

A

Long-acting glucocorticoids are eliminated from the body very slowly. This prolongs side effects, suppresses the body’s production of natural glucocorticoids, and makes it difficult to taper off the dose effectively.

CP Student #9 McCurnin 9th ed. #972

35
Q

What is Furosemide’s mechanism of action?

A

It inhibits sodium, potassium, and chloride reabsorption in the Loop of Henle. Therefore more sodium is being excreted which will cause more water to be excreted as well.

CP Student #9 McCurnin 9th ed. #967, 969

43
Q

What is a steady state refer to?

A

Where the amount of drug administered is equal to the amount of drug being eliminated
