Bioekvivalentnost

Poređenje profila bioekvivalentnosti 150 mg bupropiona sa produženim dejstvom koji proizvede različita preduzeća.

Bioekvivalentnost je farmakokinetički termin koji se koristi za poređenje očekivane biološke in vivo ekvivalencije lekova različitih proivođača. Ako su proizvodi bioekvivalentni oni moraju da budu identični u svakom pogledu.

Birket je 2003. definisao bioekvivalenciju na sledeći način, „dva farmaceutska proizvoda su bioekvivalentna ako su farmaceutski ekvivalentna i njihove bioraspoloživosti (brzine i stepeni dostupnosti) nakon administracije u istoj molarnoj dozi su slične u toj meri da se može očekivati da je njihovo dejstvo, u pogledu efikasnosti i bezbednosti, esencijalno isto. Farmaceutska ekvivalencija podrazumeva istu količinu iste aktivne supstance u datom obliku doziranja, pri istom načinu administracije i zadovoljavanja istih ili uporedivih standarda.“[1]

FDA definiše bioekvivalenciju kao, „odsustvo znatnih razlika u brzini i meri u kojoj aktivni ingredijent ili aktivni sastojak u farmaceutskim ekvivalentima ili farmaceutskim alternativama postaje dostupan na mestu dejstva leka kad se administira u istoj molarnoj dozi pod sličnim uslovima u podesno dizajniranoj studiji.“[2]
