摘要：
The present invention provides polymersomes comprising non-biodegradable amphiphilic block-copolymers and their enteral (e.g., oral) or topical use in the treatment of an ammonia or ammonia methylated analog-associated disease or disorder or symptom thereof (e.g., hyperammonemia or trimethylaminuria). More particularly, it provides a polymersome comprising (a) a membrane, which comprises a block copolymer of poly(styrene) (PS) and poly(ethylene oxide) (PEO), wherein the PS/PEO molecular weight ratio is higher than 1.0 and lower than 4.0； and (b) a core which encloses an acid. It also provides a method of making the polymersome comprising mixing the copolymer-containing organic solvent phase with an aqueous phase containing the acid.
