Mrs. Jones, age 76, takes an aspirin as anticoagulant therapy. When the rheumatologist sees her, she is given a prescriptions for ibuprofen 800mg TID for arthritis. 1. Will taking these two medications together affect the absorption rate of either drug? Explain your answer. 2. What side effects and adverse reactions should Mrs. Jones watch for with aspirin? 3. What are some of the age related polypharmacy problems associated with chronic pain control?

Step 1
Taking aspirin and ibuprofen together may affect the absorption rate of either drug. Aspirin and ibuprofen are both nonsteroidal anti-inflammatory drugs (NSAIDs) and can compete with each other for binding sites on plasma proteins, which may alter the absorption Show more…

Problem #4: Arthritis is a painful, chronic inflammation of the joints. An experiment on the side effects of pain relievers examined arthritis patients to find the proportion of patients who suffer side effects when using ibuprofen to relieve the pain. 440 subjects with chronic arthritis were given ibuprofen for pain relief: 23 subjects suffered from adverse side effects. If more than 3% of users suffer side effects, the Food and Drug Administration will put a stronger warning label on packages of ibuprofen. Is there sufficient evidence that stronger warning labels are needed? a) Write hypotheses to test this claim; use α = 0.05. Explain why you should use a one-sided alternative. b) You may assume any necessary conditions have been met. Perform your test: If your conclusion from part b) was found to be incorrect, what type of error did you make? d) In this situation, do you think a Type I error or Type II error is more serious? Explain. e) Give a 95% confidence interval for the proportion of subjects who will suffer side effects.

A low dose of aspirin is often recommended for patients who are at risk for coronary artery disease. Low- dose aspirin contains 81 mg of acetylsalicylic acid per tablet. How many grams of acetylsalicylic acid will a patient have taken over the course of 5.0 years if he or she takes one aspiring tablet daily?

Mrs. A has been taking high doses of glucocorticoids for much of the past 2 years to control severe rheumatoid arthritis. She has now developed hypertension and type 2 diabetes and would like to stop taking the cortisone because of the unwanted changes in her appearance. How does Cushing's syndrome affect the individual? Discuss how hypertension and diabetes have developed and the potential complications of these conditions. Discuss other potential problems that Mrs. A may experience resulting from long-term use of glucocorticoids.
