Abstract
A solid sustained-release preparation in the form of a needle-like or bar-like shape, which consists essentially of an active ingredient and a pharmaceutically acceptable biodegradable carrier (e.g. proteins, preferably collagen, gelatin, and a mixture thereof). The sustained release preparation can be administered to the body or implanted into the body by injection or an injection-like method and can release the active ingredient at an effective level for a long period of time when administered.
