Seftolozan/tazobaktam yeni kuşak sefalosporin ve β-laktamaz inhibitörü kombinasyonu olan bir antibiyotiktir. On sekiz yaş ve üzerindeki erişkinlerde meydana gelen komplike üriner sistem enfeksiyonları ve metronidazol ile kombine edilerek komplike intraabdominal enfeksiyonların tedavisinde Amerikan Gıda ve İlaç Dairesi onayı almıştır. Başlıca etki spektrumu çoklu ilaç dirençli (ÇİD) Pseudomonas aeruginosa ve diğer aerobik Gram-olumsuz bakterilerdir (GNB). Başlıca karakteristik özellikleri: (1) P. aeruginosa’nın penisilin bağlayan proteinlerine yüksek afinitesi olması, (2) dış membran penetrasyonunun yüksek olması ve bu nedenle efluks pompası aktivitesinden daha az etkilenmesi, (3) AmpC β-laktamaz, primitif b-laktamazlar (TEM-1, TEM-2, SHV-1 ve OXA-1) ve genişlemiş spektrumlu β-laktamaz olumlu bakterilere etkili olmasıdır. Buna karşın, metallo-β-laktamaz ve Klebsiella pneumoniae karbapenemazları enzimleri üreten patojenlere etkisizdir. Seftolozan/tazobaktamın özellikle tedavi seçeneğinin kısıtlı olduğu ÇİD GNB’nin neden olduğu enfeksiyonların tedavisinde faydalı olacağı düşünülmektedir. Bu yazıda, henüz ülkemizde kullanıma girmemiş olan bu antibiyotiğin farmakokinetik özellikleri, antimikrobiyal spektrumu ve güncel çalışmalardaki verileri derlenmiştir.
