Nanocrystals: An Approachable Delivery System for Anticancer Therapeutics

Area of Science:

• Pharmaceutical Sciences
• Materials Science
• Oncology

Background:

• Hydrophobic anticancer drugs often exhibit poor aqueous solubility, limiting their bioavailability and therapeutic efficacy.
• Over 40% of new therapeutic molecules in early drug development are hydrophobic, posing a significant challenge.
• Drug nanocrystals (NCs) have emerged as a promising drug delivery system to address these limitations.

Purpose of the Study:

• To review the manufacturing processes, biological fate, and therapeutic applications of drug nanocrystals (NCs) for cancer treatment.
• To highlight the advantages of NCs, including tailored dissolution, high drug loading, extended circulation, and structural stability.
• To discuss future perspectives for NCs in cancer management.

Main Methods:

• Review of existing literature on drug nanocrystal formulation and application in cancer therapy.
• Analysis of various manufacturing approaches, including top-down, bottom-up, and combination technologies.
• Examination of the biological fate and therapeutic outcomes of nanocrystal-based anticancer drugs.

Main Results:

• Drug nanocrystals (NCs) demonstrate enhanced physicochemical properties beneficial for drug delivery.
• Numerous hydrophobic anticancer drugs, such as paclitaxel and camptothecin, have been successfully formulated as NCs.
• Various formulation technologies facilitate the development of effective nanocrystal-based cancer therapeutics.

Conclusions:

• Drug nanocrystals represent a significant advancement in overcoming bioavailability challenges for hydrophobic anticancer agents.
• NCs offer a versatile platform for improving the efficacy and delivery of cancer therapeutics.
• Further research into NCs holds promise for improved cancer management strategies.
