Delivery strategies for antiparasitics

Area of Science:

• Drug development and formulation science
• Parasitology and infectious diseases
• Biotechnology and nanomedicine

Background:

• Modern drug development requires tailored strategies for infectious agents and diseases.
• Antiparasitic drug formulation presents unique challenges due to pathogen peculiarities.
• Optimizing drug delivery is crucial for enhancing therapeutic efficacy.

Purpose of the Study:

• To review rational design principles for antiparasitic drug formulations.
• To discuss various drug carrier systems and their functional properties.
• To evaluate the therapeutic efficacy of these systems against specific parasitic diseases.

Main Methods:

• Review of existing literature on drug carrier systems for antiparasitic drugs.
• Analysis of delivery systems including nano- and microparticles, liposomes, emulsions, cochleates, and bioadhesive macromolecules.
• Discussion of biopharmaceutical and pathophysiological parameters influencing drug delivery.

Main Results:

• Various carrier systems show promise for antiparasitic drug delivery.
• Efficacy demonstrated for leishmaniasis, human African trypanosomiasis, cryptosporidiosis, malaria, and schistosomiasis.
• Key parameters for successful application include route of administration and targeting intracellular pathogens.

Conclusions:

• Optimized drug carrier systems are essential for effective antiparasitic therapies.
• Rational design must consider disease-specific and pathogen-specific factors.
• Future research should focus on improving body distribution and intracellular targeting.
