Questions and Answers

What is the difference between therapeutic and pharmacologic classifications?

Therapeutic classification organizes drugs based on their usefulness in treating diseases, while pharmacologic classification refers to how an agent works at the molecular, tissue, and body system levels.

Identify the following classifications as therapeutic or pharmacologic: beta-adrenergic blocker, oral contraceptive, laxative, folic acid antagonist, and antianginal drug.

Laxative - Therapeutic (correct)
Antianginal drug - Therapeutic (correct)
Oral contraceptive - Therapeutic (correct)
Beta-adrenergic blocker - Pharmacologic (correct)
Folic acid antagonist - Pharmacologic (correct)

What is a prototype drug, and how does it differ from other drugs in the same class?

Prototype drugs exhibit typical features of their class, helping to anticipate the actions and adverse effects of other drugs in that class.

Explain why a patient might seek treatment from an OTC drug instead of a more effective prescription drug.

Therapeutic classification

Organizes drugs based on their usefulness in treating diseases.

Pharmacologic classification

Refers to how an agent works at the molecular, tissue, and body system levels.

Prototype drug

A drug that exhibits typical features of its class and helps predict the actions and adverse effects of other drugs in that class.

Why OTC drugs are preferred

Patients might prefer OTC drugs for convenience, lower cost, or to avoid the need for a prescription.

Study Notes

Therapeutic vs. Pharmacologic Classifications

Therapeutic classification organizes drugs based on their usefulness in treating specific diseases.
Pharmacologic classification explains how an agent works on a molecular, tissue, and body system level.
Examples of classifications:
- Beta-adrenergic blocker: Pharmacologic
- Oral contraceptive: Therapeutic
- Laxative: Therapeutic
- Folic acid antagonist: Pharmacologic
- Antianginal drug: Therapeutic

Prototype Drug

A prototype drug is a standard representative of a specific class of drugs.
Understanding the prototype helps anticipate the actions and side effects of other drugs within that class.

OTC vs. Prescription Drugs

Patients may choose OTC drugs for convenience, cost savings, and accessibility, despite potentially seeking more effective prescription medications.

Generic-Equivalent Drugs

Generic drugs can be substituted for trade-name medications unless restricted by a negative formulary or a prescriber/patient request.
Advantages of substitution:
- Cost savings for patients.
- Consistent naming across manufacturers.
Disadvantages may arise due to variations in inert ingredients, potentially impacting drug efficacy and target cell accessibility.
