MARKHAM, ON, Nov. 7 /PRNewswire-FirstCall/ - AlphaRx (OTC BB:ALRX) ispleased to announce pre-clinical data on Vansolin(TM), a Vancomycin compoundencapsulated in the company's Nano Drug Delivery Platform intended for thetreatment of nosocomial pneumonia.

In the recent clinical trial, mice treated with Vansolin(TM) in a MurineModel of Pneumonia showed better efficacy than Vancomycin, achieving 100%survival rate vs. 30% in the Vancomycin treatment group. With these results,Vansolin(TM) is now on track to enter into human trials in 2008.

These results support The Company's belief that encapsulating Vancomycininto AlphaRx's nano-particle formulation may increase its efficacy. Accordingto published research papers, in vitro uptake of Vancomycin nanoparticles bywhite blood cells is 20 times greater than free drug. The Company anticipatesthat in vivo, after IV infusion, white blood cells will readily absorbVansolin nanoparticles and transport them to the site of inflammation andinfection, thereby increasing the local concentration of Vancomycin andultimately increasing its bactericidal effect.

What's more, in the Murine Model of Pneumonia, Vancomycin encapsulated inthe company's Nano Drug Delivery platform administrated by injection of 1mg/kg, is more effective than injecting 10 mg/kg, in a conventionalformulation in terms of mortality. The 90% reduction in dosage is significant,in that it may reduce potential toxicity effects of Vancomycin and may reducetreatment days from 10 days to 3 days.

Currently, the Company has four nano products in the development pipelinewith an estimated annual market sales potential of over US$6.0 billiondollars.
