Akarboza je antidijabetesni lek koji se koristi za tretiranje tipa 2 diabetes mellitusa i, u nekim zemljama, predijabetesa. On je u prodaji na slobodno u Evropi i Kini kao Glucobay (Bajer AG), u Severnoj Americi kao Precose, i u Kanadi kao Prandase.^[6] Ovaj lek je blokator skroba. On inhibira alfa glukozidaze. Sastoji se od akarviozinske grupe sa maltozom na redukujućem terminusu.

Mehanizam dejstva[uredi - уреди | uredi izvor]

Akarboza inhibira enzime (glikozidne hidrolaze) neophodne za varenje ugljenih hidrata, specifično, alfa-glukozidazne enzime u obodu tankih creva i pankreatičnu alfa-amilazu. Pankreatična alfa-amilaza hidrolizuje kompleks skroba do oligosaharida u lumenu tankih creva, dok za membranu vezane intestinalne alfa-glukozidaze hidrolizuju oligosaharide, trisaharide, i disaharides do glukoze i drugih monosaharidas. Inhibicija ovih enzimskih sistema redukuje brzinu varenja kompleksnih ugljenih hidrata. Manje glukoze se apsorbuje, jer u manjoj meri dolazi do razlaganaja oligosaharida. Kod dijabetičkih pacijenata, kratkotrajno dejstvo leka je sniženje nivoa glukoze; a dugotrajni efekat je redukcija Hb_A1c nivoa.^[7] To dovodi do sniženja od oko 10% tipičnih Hb_A1c vrednosti u studijama dijabetesa.^[8]
