    摘要: This invention relates to a vaginal/ano-rectal applicator for the uniform delivery of any topical formulations to treat and/or prevent any infection and/or abnormal conditions of mucosa cavity caused by any pathogen and/or disease. The present applicator comprises a longitudinally extending body that has proximal and distal ends. The proximal end is located close to the external site of a mucosal cavity accessible to a user. The body has external perforations, made as a series of slots or holes, for uniform distribution of any formulation to be delivered to the user's mucosal cavity. Upon insertion of the applicator and expulsion of the formulation in the mucosal cavity, the formulation, which is contained in a reservoir, travels through a diffusion channel having a small volume, prior to being expelled through the perforations.

    摘要: A method is disclosed for the treatment of viral diseases comprising the administration of antiviral agents encapsulated in liposomes. Also provided are formulations of liposomes for the treatment of viral diseases and more particularly for the treatment of infections caused by viruses like human immunodeficiency virus (HIV) and cytomegalovirus (CMV). These formulations of liposomes are composed of specific classes of lipid components and contain an entrapped drug effective against the viral disease. These liposomal formulations of antiviral drugs allow high cellular penetration in different cell lines, good in vitro antiviral efficacy against HIV and CMV replication, efficient in vivo targeting of HIV reservoirs and a marked improvement of the pharmacokinetics of drugs.
