Actions and Spectrum:Â
tinidazole is an antiprotozoal and antibacterial medication used to treat infections caused by protozoa and anaerobic bacteria. It works by disrupting the target organism’s DNA synthesis and replication processes, leading to its deathÂ
tinidazole has a broad spectrum of activity against anaerobic bacteria and protozoa, including:Â
Frequency definedÂ
1-10%Â
Weakness/fatigue/malaise (1-2%)Â
Dysgeusia (4-6%)Â
Headache (<1%)Â
Dizziness (<1%)Â Â
Anorexia (2-3%)Â
Dyspepsia (1-2%)Â
Vomiting (1-2%)Â
Constipation (<1%)Â
Nausea(3-5%)Â
Frequency not definedÂ
Leukopenia/neutropenia urineÂ
Tongue & AtaxiaÂ
Candida paresthesiaÂ
DiarrheaÂ
Darkened neuropathyÂ
Numbness overgrowthÂ
Convulsions discolorationÂ
Transient peripheral & transientÂ
Black box warning:Â
The U.S. Food and Drug Administration (FDA) has issued a black box warning for tinidazole regarding the potential risk of carcinogenicity in laboratory animals. Long-term animal studies have shown that high doses of tinidazole can cause liver tumors in mice and ratsÂ
Contraindications/caution:Â
Contraindications:Â
tinidazole is contraindicated in patients with a known hypersensitivity to the drug or its components. Additionally, tinidazole should not be used in patients with a history of hypersensitivity to other nitroimidazole derivatives, such as metronidazole. It is also contraindicated in the following conditions:Â
Caution:Â
Several cautions should be considered before using tinidazole. These include:Â
Pregnancy consideration: CÂ
Lactation: It can be excreted into breast milk, and its use during breastfeeding is not recommendedÂ
Pregnancy category:Â
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.  Â
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data available with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.   Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.   Â
Category N: There is no data available for the drug under this categoryÂ
Pharmacology:Â
tinidazole is a synthetic nitroimidazole antibiotic that is structurally related to metronidazole. It exerts its pharmacological effect by disrupting anaerobic microorganisms’ DNA synthesis and replication processes, leading to their deathÂ
Pharmacodynamics:Â
tinidazole is a synthetic antiprotozoal agent effective against Trichomonas vaginalis, Giardia duodenalis (G. lamblia), and Entamoeba histolytica. It works by disrupting these protozoa’s DNA synthesis and replication processes, leading to their deathÂ
tinidazole is ineffective against most strains of vaginal lactobacilli, which are beneficial bacteria that maintain a healthy vaginal environment. However, tinidazole can disrupt the average balance of vaginal flora and increase the risk of secondary infections, such as vaginal candidiasisÂ
Pharmacokinetics:Â
AbsorptionÂ
tinidazole is rapidly and completely absorbed after oral administration, with a bioavailability of approximately 100%. It can be taken with or without food, and food does not significantly affect absorption. Peak plasma concentrations are achieved within 2-4 hours after a single oral doseÂ
DistributionÂ
 tinidazole has a high volume of distribution (Vd) of approximately 50 L, indicating that it is widely distributed throughout the body. It is highly protein-bound (>99%), primarily to albumin. Â
MetabolismÂ
tinidazole is metabolized in the liver by oxidation and conjugation to form hydroxylated and glucuronidated metabolites. The metabolites are eliminated mainly in the urine and feces. The elimination half-life of tinidazole is approximately 12-14 hours. Â
Elimination and ExcretionÂ
tinidazole and its metabolites are eliminated mainly in the urine and feces, with approximately 50-60% of the dose excreted and 20-25% in the feces. Renal elimination is the primary route of elimination, and dosage adjustments are recommended for patients with renal impairmentÂ
Administration:Â

Generic Name: tinidazoleÂ

Why do we use tinidazole?Â
tinidazole is a synthetic antiprotozoal agent that is used to treat a variety of infections caused by protozoa, including:Â
