藥物的效用有時候因人而異,其中一道原因,可以歸究於每個人體內的腸道細菌品種有所不同所致。389Please respect copyright.PENANAotDg8VJHYe

(圖2)口服藥物要抵達血管循環系統的話,無可避免將會途經我們的腸道。389Please respect copyright.PENANAMJZ8o6ZgCa
而我們腸道的細菌有能力改造或代謝藥物,因而改變藥物結構及其效用。389Please respect copyright.PENANAycIlvoIcIi

(圖3)有科學家找來人體最為常見的76種腸道細菌品種,與271款不同界別常用的藥物共同放在一起12小時。389Please respect copyright.PENANAUZTRnj8tBL
389Please respect copyright.PENANAZ1eDJIORI9
389Please respect copyright.PENANAn5dBgQnkLE
最終發現,271款藥物中,有多達176款藥物的濃度在被至少一種腸道細菌影響下,濃度減少了20%;389Please respect copyright.PENANAqh8mvnG6VS
而這些腸道細菌品種每款可以代謝11-95款藥物不等。389Please respect copyright.PENANAMg7ljAf5my

用上老鼠作動物模型,科學家更能找出所屬細菌哪一條基因負責消化/代謝藥物,引證腸道細菌影響藥物吸收的理念。389Please respect copyright.PENANAk3CtaIIFCA
389Please respect copyright.PENANAG3E9gcPGpZ
倘若你腸道恰巧住有細菌A,而細菌A又有能力吸收你所口服的藥物,那麼藥效便有可能會大大減低。389Please respect copyright.PENANAKvJ5cNoRqs

血液注射而非口服的藥物將有機會不受此限,因為藥物並不需一定要經過腸道裡頭。389Please respect copyright.PENANAqjN1ohMq9I
