Targeted Drug Delivery: Trends and Perspectives

Area of Science:

• Pharmaceutical Sciences
• Biomedical Engineering

Background:

• Conventional drug delivery systems face limitations in drug degradation and off-target effects.
• Effective drug delivery requires precise targeting to the intended site and appropriate dosage.
• Targeted drug transport aims for localized action, minimizing systemic exposure and enhancing safety.

Purpose of the Study:

• To review and discuss advanced drug targeting techniques for improved therapeutic outcomes.
• To highlight mechanisms enabling precise drug delivery to specific anatomical locations.
• To underscore the benefits of targeted delivery, including reduced side effects and enhanced patient compliance.

Main Methods:

• Exploration of various drug targeting strategies, including enzyme mediation, pH-dependent release, and receptor targeting.
• Review of specialized vehicles designed for focused drug transport.
• Analysis of techniques for achieving localized drug interaction with diseased tissues.

Main Results:

• Targeted drug delivery systems enable the precise delivery of therapeutic agents to desired sites of action.
• Advanced methods minimize drug degradation and ensure optimal dosage at the target site.
• Intelligent systems reduce the likelihood of dose dumping and dosage form failure.

Conclusions:

• This review covers current and emerging drug targeting techniques for delivery to specific sites like the colon and brain.
• The findings suggest that novel drug targets can be identified and leveraged for successful targeted therapies.
• Further research into advanced targeting strategies is crucial for optimizing drug delivery and treatment efficacy.
