The enhancing effect of fatty acids on the rectal absorption of acyclovir has been evaluated in rats. Acyclovir proved to be absorbed to the extent of 3 to 9% after oral administration. After rectal administration in the absence of absorption-promoter, the bioavailability of acyclovir was 37%. Its rectal administration with 4% sodium caprate resulted in enhanced bioavailability (81 +/- 3%).
