Abstract
Novel photocleavable drug conjugates for forming drug depots comprise drugs attached to photocleavable groups. In one embodiment, the drug is linked via photocleavable group(s) to a polymer chain to form a photocleavable drug-polymer conjugate that generally forms the depot matrix. In another embodiment, the drug is crosslinked via photocleavable group(s) to themselves to form a photocleavable drug conjugate that generally forms the depot.
