• A. Introduced into tissues
• B. taken orally
• C. Used in place of suppository
• D. Placed on the skin to release the drug

Hint:

Implants are strictly sterile and must be biocompatible to avoid tissue rejection.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Implantable drug delivery systems are sterile devices designed to be inserted into the body to release drugs at a controlled rate.

Step 2: Detailed Explanation:
Implants are placed directly into body tissues (such as subcutaneous, intramuscular, or specific organ sites) via minor surgical procedures or trocars.
Once in the tissue, they slowly release the drug over days, months, or even years, maintaining localized or systemic levels.
Examples include contraceptive rods or specialized chemotherapy delivery devices.

Step 3: Final Answer:
An implant is a device surgically introduced into tissues for sustained drug release.
