Data Shows Maxorb(R) Extra Ag Capable Of Sustaining Antimicrobial Activity For Up To 21 Days

Medline Industries,
Inc., the nation’s largest privately held manufacturer and
distributor of medical supplies, today announced that the U.S. Food
and Drug Administration (FDA) has granted 510(k) clearance supporting
the claim that Maxorb(R) Extra Ag is capable of sustained
antimicrobial activity for up to 21 days.(1) Maxorb Extra Ag is a
non-woven, soft-gelling, highly absorbent carboxymethylcellulose
(CMC) calcium alginate dressing containing antimicrobial ionic

“Maxorb’s 21 days of sustained antimicrobial efficacy is five times
longer than the initial duration established in 2004 and is longer
than many other ionic silver dressings’ claim,” said Debashish
Chakravarthy, PhD, FAPWCA, Vice President of Technology for Medline
Advanced Skin and Wound Care. “The data also highlights Maxorb’s
ability to act as an antimicrobial barrier to microbes in the
dressing, an ability that was less evident in a 100% CMC-silver
product that was compared to Maxorb Ag.”

A key benefit of Maxorb’s extended and sustained antimicrobial
efficacy is that it increases the potential wear time of the
dressing. In a multinational survey, practitioners consistently rated
dressing removal as the time of greatest pain for patients. Forty
percent said that the worst part of living with an ulcer was pain at
dressing change.(2) Maxorb’s increased wear time means the wound can
remain undisturbed for a longer period, thus extending the time
between potentially painful cyclic events.

About Maxorb(R) Extra Ag

Made of a combination of non-woven alginate and CMC fiber, Maxorb
Extra Ag is seeded with an ionic silver compound called silver sodium
hydrogen zirconium phosphate. Exposure to the sodium in wound exudate
stimulates the continuous release of silver ions, providing
antimicrobial protection over a broad spectrum of bacteria and fungi,
including MRSA and VRE. As wound fluid is absorbed by the alginate,
it forms a gel, which assists in maintaining a moist environment for
optimal wound healing. The added presence of CMC improves the
absorbency, gelling and fluid handling ability as well as adding
improved wet strength.

It is indicated for use in postoperative (surgical) wounds,
first-and-second degree burns, trauma wounds, leg ulcers, pressure
ulcers, graft and donor sites, diabetic ulcers and partial-and-full
thickness wounds. While using Maxorb Extra Ag, systemic antimicrobial
therapy should be considered when wound infection is evident. Maxorb
Extra Ag wound dressings may be used, under medical supervision, in
conjunction with systemic antibiotics.

Medline has also added a new 8″x12″ (20 x 30.5cm) size dressing to
accommodate large surface area wounds.
