Secnidal DS Tablet 1000 mg is selective against many anaerobic Gram-positive and Gram-negative bacteria and protozoa. It is a single-dose oral treatment for bacterial vaginosis, which is a common vaginal infection in women aged 15 to 44 years. The antimicrobial therapy is only intended to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria .

Secnidal DS Tablet 1000 mg is a nitroimidazole antimicrobial drug that displays selectivity against many anaerobic Gram-positive and Gram-negative bacteria and protozoa . In vitro studies demonstrates the effectiveness of the drug against Bacteroides fragilis, Trichomonas vaginalis, Entamoeba histolytica and Giardia lamblia . There is no significant bacterial or protozoal resistance reported from secnidazole treatment .

Secnidal DS Tablet 1000 mg enters the bacterial cell as a prodrug without an antimicrobial activity. The drug is converted to an active form via reduction of nitro groups to radical anions by bacterial enzymes. The radical anions are thought to interfere with bacterial DNA synthesis of susceptible isolates .

Secnidal DS Tablet 1000 mg is rapidly and completely absorbed after oral administration . Following a single oral dose of 2 g in healthy adult female subjects, the mean (SD) secnidazole peak plasma concentration (Cmax) of 45.4 (7.64) mcg/mL and mean (SD) systemic exposure (AUC0-inf) of 1331.6 (230.16) mcg x hr/mL was reached. Median (range) time to peak concentration (Tmax) was 4.0 (3.0-4.0) hours .

The apparent volume of distribution of secnidazole is approximately 42-49 L .

The plasma protein binding of secnidazole is < 5-15% .

The predominant route of elimination is renal elimination. Following a single oral dose of 2g secnidazole, approximately 15% of the drug is excreted as unchanged compoung in the urine .

The plasma elimination half-life for secnidazole is approximately 17 hours .

The total body clearance of secnidazole is approximately 25 mL/min. The renal clearance of secnidazole is approximately 3.9 mL/min .

Oral LD50 in mouse, rabbit and rat is 300 mg/kg, 3200 mg/kg and 980 mg/kg, in a respective order . Secnidal DS Tablet 1000 mg was positive in the Bacterial Reverse Mutation Assay, but was negative for the rat micronucleus test and mouse lymphoma test. No parental toxicity or signs of reproductive toxicity were observed in female rat fertility studies at doses of up to the maximum tolerated dose of 300 mg/kg/day .
