Abstract
An ophthalmic composition comprising geranylgeranylacetone and a phosphate buffering agent has an advantage that the loss of the geranylgeranylacetone content during long-term storage is very little. This is because of reduced adsorption of geranylgeranylacetone to a wall of an ophthalmic container. The ophthalmic composition comprising geranylgeranylacetone and a phosphate buffering agent also has an advantage that adsorption of geranylgeranylacetone to a contact lens is little. Further, the ophthalmic composition comprising geranylgeranylacetone and a phosphate buffering agent hardly becomes white turbid even when stored at low temperature.
