This invention provides compositions for controlled localized depositing of one or more drugs within a subject. More particularly, described herein are compositions comprising a) a polyethylene glycol (PEG) composition having a first low molecular weight PEG (Mw between 200-500 Da) and a second low molecular weight PEG (Mw between 500-2000 Da) and b) a mucoadhesive polymer. Alternatively, composition may comprise a) a polyethylene glycol (PEG) composition having a first low molecular weight PEG (Mw between 200-500 Da) and a second low molecular weight PEG (Mw between 500-2000 Da), b) a water insoluble polymer and c) a mucoadhesive polymer. Furthermore, the composition may further comprise one or more drugs. Also provided are methods of manufacturing and administering the compositions described herein, which are used as biodegradable, injectable mucoadhesive low-viscosity pastes. |
