All of the following statements regarding Dronabinol are correct except?

Appeared in: INI-CET EXAM -2025

Explanation

  • The statement that Dronabinol is excreted unchanged in the urine is incorrect.
  • Dronabinol is a highly lipophilic drug that undergoes extensive first-pass metabolism in the liver by the cytochrome P450 enzyme system.
  • It is converted into active and inactive metabolites.
  • These metabolites, not the unchanged drug, are then excreted from the body, primarily via the feces and to a lesser extent in the urine.

Why Other Options Were Wrong

  • Option A: This is a correct statement. While not a primary FDA-approved indication for Dronabinol itself, cannabinoids as a drug class are recognized for their analgesic properties and are used in the management of chronic and neuropathic pain.
  • Option C: This is a correct statement. Dronabinol is a synthetic form of delta-9-tetrahydrocannabinol (THC), the primary psychoactive component of cannabis. Its therapeutic effects are mediated by acting as an agonist at cannabinoid receptors, primarily the CB₁ receptors found in the central nervous system.
  • Option D: This is a correct statement. Dronabinol is FDA-approved for the treatment of anorexia associated with weight loss in patients with Acquired Immunodeficiency Syndrome (AIDS). It acts as an appetite stimulant in this population.

  • Visual 2: Diagram - A simple diagram of the endocannabinoid system showing the CB1 and CB2 receptors to illustrate the drug's mechanism of action.
Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pharmacology of Dronabinol as background academic context rather than a clinical decision trigger.
  • Nurses administering Dronabinol must monitor for common side effects, including CNS effects like drowsiness, dizziness, confusion, and euphoria. Patients should be cautioned against driving or operating heavy machinery.
  • Cardiovascular effects such as tachycardia and hypotension can occur, requiring monitoring of heart rate and blood pressure, especially in patients with pre-existing heart conditions.
  • Patient education is crucial. The nurse should explain that the drug is intended to help with appetite or nausea and discuss potential psychoactive effects.
How to Approach the Question
  • First, identify that the question uses the word 'except'. This means you are looking for the statement that is FALSE.
  • Read the stem of the question to identify the core subject: the drug Dronabinol.
  • Evaluate each option independently based on your knowledge of pharmacology.
  • Option A: Recall the uses of cannabinoids. Are they used for pain? Yes.
  • Option B: Consider the pharmacokinetics. Are drugs, especially lipophilic ones, often excreted unchanged? No, they are usually metabolized first. This should be a red flag.
  • Option C: Think about the drug class. Dronabinol is a cannabinoid. How do they work? By acting on cannabinoid receptors.
Concept Tested & Keywords
  • Concept Tested: Pharmacology of Dronabinol
  • Stem keywords: Dronabinol, pharmacology
  • Lead-in keywords: except
  • Negative lead-in flag: This is a negative-lead-in question, asking you to identify the INCORRECT statement.
