Pravni status

MK-677 (L-163,191) je lek koji deluje kao potentan1, oralno aktivan izlučivač hormona rasta.[3][4] On oponaša GH stimulišuće dejstvo endogenog hormona grelina.[5][6] Pokazano je da povišava oslobađanje i održava povišene nivoe u plazmi nekoliko hormona među kojima su hormon rasta i IGF-1, i da nema uticaje na nivoe kortizola.[7]

On je trenutno u razvoju kao potencijalni tretman za redukciju nivoa tih hormona, kao što je nedostatak hormona rasta kod dece ili starijih odraslih osoba.[8][9][10] Klinička ispitivanja su pokazala da povećava mišićnu masu i gustinu minerala kostiju,[11][12] što ga potencijalno čini podesnim za lečenje slabosti starijih osoba.[13][14] On takođe menja metabolizam telesne masnoće tako da možda može da nađe primenu u lečenju gojaznosti.[15][16]
