Properties of İdeal Drug Delivery

Targeting

• It should be -o N-on-t-oxic o Biocompatible o Biodegradable

o Physicochemical stable both in-vivo & in-vitro • Controlled and predictable drug release

• Minimal drug leakage

• Carrier should be readily eliminated without causing any change in

diseased state

• Preparation should be easy, reproductive and cost effective • Drug release should not effect drug action

Briefly;

ADVANTAGES

• Reduction of drug side-effects

• Reduced frequency of drug intake

• Reduced dose of drug • Uniform blood level of drug

• Maximizes the therapeutic

index

DISADVANTAGES

• Rapid clearance of targeted systems

• Immune reaction against carrier systems

• Insufficient localization of targeted systems in tumor cells

• Diffusion and redistribution of released drug
