Question

Two drugs producing the same clinical effects and safety profile when administered to patients are considered:

• A. Minimum Toxic Concentration (MTC)
• B. Minimum Effective Concentration (MEC)
• C. Therapeutic equivalent
• D. Therapeutic window

Hint:

Therapeutic equivalence ensures two drugs have the same clinical effect and safety, often essential in substituting generic drugs for branded ones.

Answer 1

The Correct Option is C

Step 1: Understanding therapeutic equivalence. Therapeutic equivalence refers to two drugs that produce the same clinical effect and have a similar safety profile when administered in the same dosage form, strength, and route of administration. These drugs may differ in inactive ingredients but must demonstrate bioequivalence (similar rate and extent of absorption). 

Step 2: Explanation of incorrect options. 
- (A) Minimum Toxic Concentration (MTC): Refers to the lowest drug concentration at which toxic effects occur, unrelated to equivalence. 
- (B) Minimum Effective Concentration (MEC): Refers to the lowest concentration required to produce a therapeutic effect, unrelated to equivalence.
- (D) Therapeutic window: Refers to the range between MEC and MTC, indicating drug safety, not equivalence.
