Summary:The technical field of the invention relates to pharmaceutical compositions of 9-(1,3-dihydroxy-2-propoxymethyl) guanine (ganciclovir) that are stable and contain more than 1% water content. One pharmaceutical composition includes ganciclovir having more than about 1% water content, and one or more pharmaceutically acceptable excipients. The ganciclovir retains at least about 97% of its initial purity after one month, at least about 96% of its initial purity after two months, and at least about 95% of its initial purity after three months when stored at 40 DEG C and 75% RH. In particular, the water content may be between about 2% and about 6%. Le domaine technique de la présente invention se rapporte à des compositions pharmaceutiques de 9-(1,3-dihydroxy-2-propoxyméthyl) guanine (ganciclovir) qui sont stables et contiennent plus de 1 % d'eau. Une composition pharmaceutique renferme du ganciclovir ayant une teneur en eau supérieure à environ 1 % et un ou plusieurs excipients pharmaceutiquement acceptables. Le ganciclovir conserve au moins environ 97 % de sa pureté initiale après un mois, au moins environ 96 % de sa pureté initiale après deux mois et au moins environ 95 % de sa pureté initiale après trois moins lorsqu'il est conservé à 40 DEG C et avec une humidité relative (HR) de 75 %. La teneur en eau peut se situer entre environ 2 % et environ 6 %.
