ATC CODE P01AB
Antimicrobial and antiprotozoal agent. Nitroimidazole derivative.
Secdaza is a nitroimidazole antiprotozoal agent with antibacterial action; it is characterized with bactericidal (against gram-positive and gram-negative anaerobe bacteria) and amebicide (intraluminal and extraluminal) effect. Secdaza is particularly active against Trichomonas vaginalis, Entamoeba histolytica, Giardia lamblia. By entering the bacterial cell secnidazole activates on consequence of the recovery of 5-nitro group; as a result it interacts with a cellular DNA. Thus, its spiral structure damage and fibre distruction, nucleotide synthesis inhibition and cell death take place.
After oral intake Secdaza is rapidly and fully absorbed from the gastrointestinal tract. The bioavailability is about 80%. Secnidazole passes through the blood-brain barrier and enters breast milk. The elimination half-life of secnidazole is approximately 25 hours that allows simplifying the drug dosage regimen by making it more convenient for patients.

In coadministration with lithium agents Secdaza increases its blood plasma concentration.
The drug is not recommended to combine with nondepolarizing muscle relaxants (vecuronium bromide).
