Soluble microneedle acupuncture patches containing melittin liposomes for the percutaneous treatment of rheumatoid arthritis.

Bee venom acupuncture (BVA) offers therapeutic potential for rheumatoid arthritis (RA) but faces challenges from pain and allergies linked to live bee stings. A key hurdle is melittin (Mel), bee venom's main anti-inflammatory component, which degrades rapidly when orally ingested, leading to decreased efficacy and increased toxicity. This study proposes a solution by encapsulating melittin in liposomes to enhance stability and lessen side effects, expanding its clinical applicability.
