A non-aqueous sustained release drug delivery system, which contains, based on the total weight of the sustained release drug delivery system, about 0.1-20% of an active agent, about 0.5-50% of a drug solvent, about 1-98% of a drug sustained release agent, about 0.1-85% of a drug solubilizer, about 0.1-10% of an efficacy enhancer, about 0-1% of an antioxidant, and about 0-8% of an acid-base regulator. The non-aqueous sustained release drug delivery system can yield an improved sustained release effect, improve bioavailability, and enhance the therapeutic effect.
