AlphaRx Updates Binoxan Development, a Potential Non-Irritating, Twice-a-Day Eye Drop for Ocular Inflammation


MARKHAM, Ontario, Jan. 17, 2006 (PRIMEZONE) -- AlphaRx Inc. (OTCBB:ALRX), an emerging biopharmaceutical company utilizing proprietary drug delivery technology to develop novel formulations of drugs, is pleased to report positive toxicology data for ALRX IM, the active ingredient in Binoxan(tm). ALRX IM is an Indomethacin Ester, which has shown comparable biological activity to standard Indomethacin formulations in animal studies, but is substantially less toxic and less irritating than the existing non-steroidal therapy. Furthermore, as ALRX IM is more soluble than Indomethacin, when incorporated into the Company's colloidal delivery platform, it may have increased permeability and correspondingly higher efficacy.

ALRX IM breaks down into Indomethacin and its ester in equal parts in vivo. Indomethacin has superior anti-inflammatory, analgesic and antipyretic properties and is normally administered in capsular form for the treatment of systemic inflammatory diseases (arthritis, muscle pain, tendinitis, etc). The sodium salt of Indomethacin may be injected intravenously or used for topically for treatment of inflammatory conditions of the eye.
