  • Composition for inhibiting transmission of hepatitis B virus
    Patent number: 5334588
    Abstract: The present invention relates to methods of inhibiting transmission of Hepatitis B virus using compositions comprising silver sulfadiazine and preferably further comprising a biguanide such as chlorhexidine and/or a detergent such as sodium deoxycholate. It is based, at least in part, on the discovery that silver sulfadiazine alone or in combination with chlorhexidine or sodium deoxycholate was shown to inhibit Hepatitis B virus DNA synthesis. The inhibitory effect of silver sulfadiazine was enhanced by combining silver sulfadiazine with either chlorhexidine or sodium deoxycholate.
