Recent studies have discussed the role of antibiotic treatment in the conservative management of acute appendicitis and whether antibiotics are a safe option to replace appendicectomy, which has been the gold standard treatment of acute appendicitis for many years. The bibliographic databases Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane, Embase, Medline, and PubMed comparing conservative versus surgical treatment of acute appendicitis were systematically searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Twenty-one studies consisting of systematic reviews and meta-analyses involving 44,699 participants were identified. At least 17,865 participants were treated with antibiotics. Our studies compare antibiotic versus appendicectomy among acute appendicitis patients ranging from 7 to 94 years of age. In most studies, patients received parenteral antibiotics for a total of one to three days, and oral antibiotics such as oral cephalosporin plus metronidazole, oral amoxicillin/clavulanate, oral fluoroquinolones plus Tinidazole upon hospital discharge for a total of 7 to 10 days. The total course of antibiotics for both parenteral and oral regimes ranged from 2 to 16 days, with 10 days being the commonest duration. The recurrence rate following initial antibiotic treatment at one-year follow-up ranged from 13% to 38%, while the mean duration of recurrence ranged from three to eight months. The majority of the patients with recurrence underwent appendicectomy, while some patients were either given a repeat or different course of antibiotics due to the possible presence of antibiotic resistance; however, only 2.4% of the patients were successfully treated upon completion of the second course of antibiotics. Most of the studies concluded that appendicectomy remains the gold standard treatment for uncomplicated acute appendicitis, given its higher efficacy and lower complication rates. Although antibiotic treatment cannot be routinely recommended, it can be considered an appropriate alternative in selected patients with uncomplicated appendicitis who wish to avoid surgery and also acknowledge the risk of recurrence and the potential need for subsequent surgery at the same time.

Within the penile microbiome, bacteria associated with seroconversion, immunology, and cells (BASIC species) enhance HIV susceptibility in heterosexual uncircumcised men by inducing foreskin inflammation and HIV target cell recruitment. This phase 1/2 clinical trial randomizes HIV-uninfected Ugandan men (n = 125) to either oral tinidazole, topical metronidazole, topical clindamycin, or topical hydrogen peroxide to define impact on ex vivo foreskin HIV susceptibility, penile immunology, and BASIC species density. Antimicrobials are well tolerated, and 116 (93%) participants complete the protocol. Topical metronidazole and oral tinidazole reduce the inner foreskin tissue density of HIV-susceptible CD4+ T cells (predefined primary endpoint). Antimicrobials also have varying but substantial effects on reducing prepuce inflammation and BASIC species density, reducing density of foreskin T cell subsets, and increasing foreskin epithelial integrity. Immune alterations correlate strongly with changes in the abundance of BASIC species. Clinical interventions targeting the penile microbiota, particularly topical metronidazole, may reduce HIV susceptibility in uncircumcised men.

How the body processes this drug — absorption, distribution, metabolism, and elimination
Tinidazole is the major drug-related constituent in plasma after human treatment, along with a small amount of the 2-hydroxymethyl metabolite.
Tinidazole is excreted in the urine mainly as unchanged drug (approximately 20-25% of the administered dose).
Approximately 12% of the drug is excreted in the feces.
