They have antagonistic actions on M3 and M5 receptors in the eye. C. They cause dilation of the pupils. D. They interfere with retinal signaling.

Answer 85

Correct Answer: B. They have antagonistic actions on M3 and M5 receptors in the eye. Explanation: Antimuscarinics are contraindicated in such patients due to their antagonistic actions on M3 and M5 receptors in the eye, which can induce or precipitate acute angle-closure glaucoma. Memory Tool: Think "M3 and M5 = No Eye" to remember that these receptor actions contraindicate the use of antimuscarinics in narrow-angle glaucoma. Reference Citation: Paragraph 30, CUA guideline on adult overactive bladder Rationale for Inclusion: Knowing contraindications, especially for special populations like those with glaucoma, is crucial for safe prescribing.

Correct Answer: C) Decrease in lean body mass leads to decreased Vd and T½ for lipophilic agents. Explanation: A decrease in lean body mass in the elderly leads to a decrease in volume of distribution (Vd) and half-life (T½) for lipophilic agents like tricyclic antidepressants. Memory Tool: "Less mass, less space for lipophilic agents to hide—Vd and T½ drop." Specific Reference Citation: (Table 3, Parameter: Distribution, Age-associated changes) Rationale: Understanding how age affects distribution is essential for proper dosing and avoiding side effects, such as dizziness in this patient.

Question 153

Question 3: Topic - Clearance and Tolterodine Clinical Vignette: You are considering prescribing Tolterodine for a 70-year-old patient with overactive bladder. You need to consider how age affects the drug's clearance. Multiple-Choice Options: A) Increase in renal clearance B) No change in renal clearance C) Decrease in renal clearance D) Fluctuating renal clearance

Answer 153

Correct Answer: C) Decrease in renal clearance Explanation: In the elderly, there is a decrease in renal clearance, which could affect the clearance of Tolterodine. Memory Tool: "Older kidneys slow down—Tolterodine lingers longer." Specific Reference Citation: (Table 3, Parameter: Clearance, Age-associated changes) Rationale: Understanding age-related changes in renal clearance is key to ensuring that drugs like Tolterodine are both effective and safe in elderly patients.

Question 154

Question 4: Topic - Hepatic Metabolism and Phase I Reactions Clinical Vignette: A 68-year-old female patient has been taking a tricyclic antidepressant for urinary incontinence. She reports feeling more sedated recently. You wonder if age-related hepatic changes could be the culprit. Multiple-Choice Options: A) Increase in Phase I hepatic reactions B) Decrease in Phase I hepatic reactions C) No change in Phase I hepatic reactions D) Phase I reactions are not relevant to tricyclic antidepressants

Answer 154

Correct Answer: B) Decrease in Phase I hepatic reactions Explanation: In elderly patients, Phase I hepatic reactions like oxidation/reduction are decreased, which can affect the metabolism of tricyclic antidepressants. Memory Tool: "Age puts a brake on Phase I, making tricyclics stick around." Specific Reference Citation: (Table 3, Parameter: Hepatic metabolism, Age-associated changes) Rationale: Understanding hepatic metabolism changes in aging is essential for medication management, particularly with medications like tricyclic antidepressants that are affected by these changes.

Question 155

Question 5: Topic - Hepatic Blood Flow and First-pass Metabolism Clinical Vignette: A 72-year-old man is newly diagnosed with overactive bladder. You're considering prescribing Oxybutynin but are cautious about the drug's pharmacokinetics in the elderly. Multiple-Choice Options: A) Increased hepatic blood flow leads to increased clearance of Oxybutynin. B) Decreased hepatic blood flow leads to increased clearance of Oxybutynin. C) Decreased hepatic blood flow and hepatic mass lead to reduced clearance of Oxybutynin. D) No change in hepatic blood flow and hepatic mass with aging.

Answer 155

Correct Answer: C) Decreased hepatic blood flow and hepatic mass lead to reduced clearance of Oxybutynin. Explanation: Elderly patients have decreased hepatic blood flow and hepatic mass, leading to reduced clearance of agents with first-pass metabolism like Oxybutynin. Memory Tool: "Older liver, slower river—Oxybutynin won't flow out as quickly." Specific Reference Citation: (Table 3, Parameter: Hepatic metabolism, Age-associated changes) Rationale: Awareness of age-related changes in hepatic blood flow and mass is vital for the proper dosing and effectiveness of medications like Oxybutynin in elderly patients.

Question 156

Question 6: Topic - Cytochrome P450 and Multiple Agents Clinical Vignette: An 80-year-old male patient is on multiple medications for urinary incontinence, including Tolterodine and Solifenacin. You consider potential drug interactions. Multiple-Choice Options: A) Cytochrome P450 affects the clearance of Tolterodine but not Solifenacin. B) Cytochrome P450 affects the clearance of Solifenacin but not Tolterodine. C) Cytochrome P450 affects the clearance of both Tolterodine and Solifenacin. D) Cytochrome P450 has no effect on the clearance of either drug.

Answer 156

Correct Answer: C) Cytochrome P450 affects the clearance of both Tolterodine and Solifenacin. Explanation: Cytochrome P450 plays a role in the clearance of both Tolterodine and Solifenacin, making it crucial to consider when these drugs are co-administered. Memory Tool: "Double trouble with P450—watch out for Tolterodine and Solifenacin." Specific Reference Citation: (Table 3, Parameter: Cytochrome P450, Age-associated changes) Rationale: Understanding the role of Cytochrome P450 in drug metabolism can prevent potential drug interactions, especially in patients on multiple medications.

Question 157

Question 7: Topic - Distribution and Protein Binding Clinical Vignette: You're treating a frail, elderly patient with low albumin levels who suffers from urinary incontinence. You're considering prescribing Tolterodine. Multiple-Choice Options: A) Decreased protein binding will lead to a lower concentration of free drug. B) Decreased protein binding will lead to a higher concentration of free drug. C) Protein binding is not affected by albumin levels. D) Tolterodine is not affected by protein binding.

Answer 157

Correct Answer: B) Decreased protein binding will lead to a higher concentration of free drug. Explanation: In frail patients with low albumin, there is decreased protein binding, leading to a higher concentration of free drug, such as Tolterodine. Memory Tool: "Low albumin? Expect Tolterodine to roam free more." Specific Reference Citation: (Table 3, Parameter: Distribution, Age-associated changes) Rationale: Recognizing the impact of albumin levels on drug distribution can guide medication dosing to prevent adverse effects.

Question 158

Question 8: Topic - Hepatic Metabolism and Phase II Reactions Clinical Vignette: You're updating your pharmacology knowledge and wonder how age affects Phase II hepatic reactions like glycosylation. Multiple-Choice Options: A) Phase II reactions are increased with age. B) Phase II reactions are decreased with age. C) Phase II reactions are not affected by age. D) Phase II reactions are variably affected by age.

Answer 158

Correct Answer: C) Phase II reactions are not affected by age. Explanation: Contrary to Phase I reactions, Phase II hepatic reactions like glycosylation do not change with age. Memory Tool: "Phase II stays true, no matter how old you are." Specific Reference Citation: (Table 3, Parameter: Hepatic metabolism, Age-associated changes) Rationale: Understanding that Phase II reactions are stable with age can assist in managing medications that undergo these types of metabolic pathways.

Question 159

Question 9: Topic - Stereoselective Metabolism Clinical Vignette: You're considering using a medication with enantiomers to treat a 75-year-old patient with urinary incontinence. You ponder the stereoselective metabolism in the elderly. Multiple-Choice Options: A) Stereoselective metabolism is confirmed in the elderly. B) Stereoselective metabolism is hypothetical in the elderly. C) Stereoselective metabolism is disproven in the elderly. D) Stereoselective metabolism is irrelevant in the elderly.

Answer 159

Correct Answer: B) Stereoselective metabolism is hypothetical in the elderly. Explanation: The selectivity in metabolism of enantiomers is still hypothetical when it comes to the elderly. Memory Tool: "Enantiomers in the elderly? Still a mystery." Specific Reference Citation: (Table 3, Parameter: Hepatic metabolism, Age-associated changes) Rationale: Knowing that the effect of age on stereoselective metabolism is not fully understood can guide cautious medication selection.
