Osmotically controlled drug delivery system with associated drugs

Area of Science:

• Pharmaceutical Sciences
• Drug Delivery Technologies
• Biopharmaceutics

Background:

• Conventional drug delivery systems exhibit limited control over drug release rates and target site concentrations, leading to unpredictable plasma levels.
• Controlled or modified-release systems aim for sustained drug delivery, with oral administration being the most preferred route.
• Challenges in oral drug delivery include low bioavailability due to poor solubility or permeability, necessitating advanced formulation strategies.

Purpose of the Study:

• To review novel technologies, fabrication methods, and recent clinical research in osmotic drug delivery systems.
• To highlight the advantages of osmotic systems for improving drug bioavailability and achieving zero-order release kinetics.
• To emphasize the suitability of osmotic drug delivery for drugs with bioavailability limitations.

Main Methods:

• Literature review of scientific publications, patents, and clinical trial data.
• Analysis of fabrication techniques for osmotic drug delivery systems.
• Synthesis of information on new technologies and their clinical applications.

Main Results:

• Osmotic drug delivery systems provide zero-order release kinetics, independent of physiological factors and initial drug concentration.
• These systems are highly effective in overcoming bioavailability challenges associated with poorly soluble or permeable drugs.
• Recent advancements have expanded the therapeutic applications and fabrication possibilities of osmotic systems.

Conclusions:

• Osmotic drug delivery represents a superior approach for achieving controlled and predictable drug release, enhancing therapeutic outcomes.
