📌 COMPOSITION
Each F/C tablet contains: Spiramycin Eur.P. 750.000 I.U – Metronidazole B.P. 125 mg.
📌 DESCRIPTION
Spiramycin is a macrolide bacteriostatic antibiotic; it has a wide spectrum of activity for the treatment of infections caused by susceptible organisms such as Streptococcus Pyogenes, Methicillin‑sensitive Staphylococcus Aureus, Chlamydia Trachomatis and Mycoplasma Pneumonia.
Metronidazole, an imidazole derivative, has marked activity against anaerobic bacteria and protozoa. Metronidazole is well absorbed after oral administration; it is excreted with its metabolites mainly in the urine (60-80%) and in the faeces (6-15%) of the dose. It has a half‑life of 8 hours. Spiramycin absorption from the gastrointestinal tract is irregular and is metabolised in the liver to active metabolites; substantial amounts are excreted in the bile and 10% in the urine. It has a half‑life of 8 hours.
