【Task】 To provide a sustained-release gel composition capable of imparting durability of the effect of a volatile drug. [Solution] A polymer compound soluble in alcohol and a compound of formula (I) [Chemical 1] [Wherein, R 1 is a C1-C10 alkyl group which may have a substituent, a C2-C10 alkenyl group which may have a substituent, and C3-C8 which may have a substituent. A cycloalkyl group, an aryl group which may have a substituent, or an aralkyl group which may have a substituent; M 1 represents a metal atom; and X represents a hydroxyl group or a hydrolyzable group. M represents the valence of M 1 , and n represents any integer of 0 or (m−2) or less. ] A sustained-release gel composition comprising an organic / inorganic composite formed from a compound represented by formula (I), a volatile drug, and an alcohol. |
