O le Telithromycin na fa'alauiloaina muamua i Siamani e fai ma togafitiga fa'ale-nu'u fa'atasi i aso ta'itasi mo fa'ama'i manava e aofia ai le niumonia e maua mai i nu'u, fa'atupu fa'ama'i pipisi o le bronchitis tumau, sinusitis ma'i ma tonsillitis/pharyngitis.O lenei semisynthetic derivative o le natura macrolide erythromycin o le muamua maketiina ketolide, o se vasega fou o vailaau faʻamaʻi faʻaalia se C3-ketone nai lo le vaega L-cladinose.O le mama e 14-membered antibacterial agent e puipuia ai le fa'aogaina o porotini siama e ala i le fusifusia i vaega e lua o le 50S subunit o ribosomes siama.O loʻo faʻaalia ai le malosi o le in vitro gaioiga e faasaga i faʻamaʻi pipisi masani e aofia ai Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis ma Streptococcus pyogenes faʻapea foʻi ma isi faʻamaʻi atypical.O le vaega 3-keto e tuʻuina atu le faʻateleina o le mautu oona ma faʻaititia le faʻaosoina o le macrolide-lincosamide-streptogramin B tetee lea e masani ona matauina i macrolides.O le toe suia o le C11-C12 carbamate e foliga mai e le gata ina faʻateleina le fesoʻotaʻiga mo le nofoaga o loʻo fusifusia ai ribosomal ae faʻamautu foi le faʻapipiʻi e faasaga i le esterase hydrolysis ma aloese mai le tetee ona o le faʻaumatiaina o macrolides mai le sela e ala i se pamu efflux ua faʻapipiʻiina e le mef gene i nisi o faʻamaʻi. .Telithromycin ose faʻatauvaʻa faʻatauvaʻa ma se mea faʻapipiʻi ole CYP3A4.Ae ui i lea, e le pei o le tele o macrolides e pei o le troleandomycin, e le fausia ai se faʻalavelave faʻamalosi CYP P-450 Fe2 + -nitrosoalkane metabolite faʻalavelave e ono mafai ona faʻamaʻi.O le vailaʻau e faʻafeiloaʻi lelei ma tufatufaina lelei i totonu o le pulmonary tissues, bronchial secretions, tonsils ma faua.E aliali mai e matua fa'atumauina i azurophil granules o polymorphonuclear neutrophils ma fa'afaigofie ai lona tu'uina atu i siama phagocytosed.
