Ray of hope to improve HIV drug therapies

Washington : A new research, through the use of nanotechnology, now aims to improve the administration and availability of drug therapies to HIV patients.

The research, led by the University of Liverpool, examined the use of nanotechnology to improve the delivery of drugs to HIV patients.

Nanotechnology is the manipulation of matter on an atomic, molecular, and supra-molecular scale. Nano-medicine is the application of nanotechnology to the prevention and treatment of disease in the human body.

This evolving discipline has the potential to dramatically change medical science and is already having an impact in a number of clinically used therapies and diagnostics worldwide.

Currently, the treatment of HIV requires daily oral dosing of HIV drugs, and chronic oral dosing has significant complications that arise from the high pill burden experienced by many patients across populations with varying conditions leading to non-adherence to therapies.

Recent evaluation of HIV patient groups have shown a willingness to switch to nanomedicine alternatives if benefits can be shown. Research efforts by the Liverpool team have focused on the development of new oral therapies, using Solid Drug Nano-particle (SDN) technology which can improve drug absorption into the body, reducing both the dose and the cost per dose and enabling existing healthcare budgets to treat more patients.

Presently, no clinically available oral nano-therapies exist for HIV populations and conventional paediatric HIV medicines are poorly available. The programme examined one current paediatric formulation that utilizes high ethanol concentrations to solubilize lopinavir, a poorly soluble antiretroviral.

Through the use of a rapid small-scale nanomedicine screening approach developed at Liverpool, the researchers were able to generate a novel water dispersible nano-therapy, hence removing the need to use alcohol in the paediatric medicine.

According to study leader Andrew Owen, “The fruits of our interdisciplinary research are beginning to be realised. Our approach has the potential to overcome challenges with current anti-retroviral therapy, which include administration of high doses needed to achieve efficacious concentrations in the body, and the urgent need for better formulations for children living with HIV.”

“The wide applicability of our strategy has implications for multiple therapy development programmes and we are actively engaged in the creation of nano-medicine options to impact a range of clinical needs,” added co-researcher Steve Rannard.

The study has been published in Nature Communications.
