Abstract

Microencapsulated virginiamycin-type antihotic compsns. for oral admin. comprise 1-30% of >=1 virginiamycin-type antibiotic coated with spermaceti contg. 1-5% of sodium lauryl sulphate. The bitter antibiotics are not liberated from the microcapsules until they reach the stomach so their unpleasant taste is not apparent. Sodium lauryl sulphate itself has no bitter taste, and unlike many similar surfactants is compatible with the antibiotics. Preferred compsns. contain about 15% antibiotic, and 2-4% sodium lauryl sulphate.
