Zusammenfassung:	Provided are methods for preparing antimicrobial elastomeric articles comprising the exposure of the articles to reduced humidity environments. In one embodiment the method comprises the following steps: coating an elastomeric article heated to 55°C ± 5°C with an antimicrobial coating composition to form an antimicrobial elastomeric article; exposing the antimicrobial elastomeric article to an environment comprising about 10.3 g/m3 or less absolute humidity; and packaging the antimicrobial elastomeric article in a packaging system; wherein the antimicrobial elastomeric article, when aged in the packaging system for 7 days at 70°C, has an antimicrobial efficacy such that the number of microorganisms present on a surface of the antimicrobial elastomeric article is reduced by at least 4 log10 within 5 minutes, wherein the steps of coating and exposing may be reversed. Examples of the antimicrobial elastomeric articles include gloves, condoms, probe covers and catheters. A preferred antimicrobial coating composition comprises the antimicrobial agent chlorhexidine gluconate.
