An emulsion composition comprising (1) a compound (I) represented by the formula (I) wherein each symbol is as defined in the specification (2) an anionic synthetic phospholipid in a proportion of about 0.0001 about 5% (W/V) relative to the composition in total, and (3) a naturally-occurring phospholipid in a proportion of about 0.1 about 10% (W/V) relative to the composition in total is provided. 

Stable emulsion composition

A sustained-release preparation comprising a bioactive substance having an acidic group and a biodegradable polymer having an optionally protected basic group which improves the rate of incorporation of the bioactive substance, suppresses its leakage early after adminstration, and exhibits constantly suppressed release for an extended period of time.

Sustained-release preparation

A sustained-release preparation comprising a bioactive substance having an acidic group and a biodegradable polymer having an optionally protected basic group which improves the rate of incorporation of the bioactive substance, suppresses its leakage early after administration, and exhibits constantly suppressed release for an extended period of time.
