Question

OROS is a technology developed for/as:

• (A) Oral release rapid onset system
• (B) Orally rapid disintegrating tablets
• (C) Osmotic controlled oral drug delivery system
• (D) Transdermal drug delivery system

Answer 1

The Correct Option is C

Explanation:
OROS is a technology developed for osmotic controlled oral drug delivery system.The osmotic-controlled release oral delivery system, OROS, is an advanced drug delivery technology that uses osmotic pressure as the driving force to deliver pharmacotherapy, usually once-daily, in several therapeutic areas. Oral route is one of the most extensively used routes of drug administration because of its obvious advantages of ease of administration, improved patient compliance and convenience. The main clinical benefits of OROS are their ability to improve treatment tolerability and patient compliance. These advantages are mainly driven by the capacity to deliver drugs in a sustained manner, independent of the drug chemical properties, of the patient’s physiological factors or concomitant food intake.Hence, the correct option is (C).

Answer 2

OROS (Osmotic-controlled Release Oral delivery System) as a technology for osmotic-controlled oral drug delivery. Several advantages of OROS, include:
1. Osmotic-controlled Release: OROS utilizes osmotic pressure to deliver drugs in a controlled manner over time.
2. Once-daily Administration: Typically, OROS systems are designed to provide once-daily dosing, which improves patient compliance.
3. Advantages of Oral Administration: The oral route is preferred due to ease of administration, improved patient compliance, and convenience.
4. Sustained Release: OROS systems can sustain drug release regardless of drug properties, physiological factors of patients, or food intake.

So, the correct option is (C): Osmotic controlled oral drug delivery system
