Figure 1.

Maraviroc concentrations in macaque vaginal fluid (a), plasma (b) and vaginal tissue (c, at 24 h) following vaginal administration of HEC gels containing various maraviroc loadings. Four animals were used to test each gel formulation. Key to symbols on graph (b) also applies to graph (a). When data points are missing, maraviroc levels were below the limit of quantification for that assay.
