A fixed-dose combination (FDC) vaginal suppository/tablet designed for the broad-spectrum treatment of mixed vaginal infections, particularly bacterial vaginosis (BV) and vulvovaginal candidiasis (VVC). Clindamycin targets anaerobic bacteria, Tinidazole targets protozoa and anaerobic bacteria, and Clotrimazole provides antifungal coverage against Candida species. This combination addresses the polymicrobial etiology of many vaginal infections, offering a convenient, single-application therapy.
Adult: One vaginal suppository/tablet (100mg each component) inserted intravaginally, preferably at bedtime, for 3 to 7 consecutive days as prescribed. A typical course is 3 days for uncomplicated infections, extended to 5-7 days for recurrent or severe cases.
Note: 1. Wash hands before and after use. 2. Remove suppository/tablet from foil wrapper. 3. Lie on back with knees bent. 4. Use applicator or finger to gently insert the suppository deep into the vagina. 5. Use during menstruation is not recommended, but if necessary, treatment can be initiated. 6. Avoid sexual intercourse during treatment. 7. Use sanitary pads to protect clothing from medication leakage/staining; avoid tampons.
This combination exerts a triple-action mechanism: 1) Clindamycin inhibits protein synthesis in susceptible anaerobic bacteria by binding to the 50S ribosomal subunit. 2) Tinidazole causes cytotoxic damage to microbial DNA after intracellular reduction of its nitro group, disrupting the helical structure. 3) Clotrimazole inhibits the synthesis of ergosterol, a critical component of fungal cell membranes, leading to increased permeability and cell death.
Pregnancy: Category C (US FDA). Tinidazole is contraindicated in the first trimester. Clindamycin and Clotrimazole are generally considered safer but should be used only if clearly needed and under strict medical supervision in the 2nd and 3rd trimesters. Avoid in first trimester.
Driving: May cause dizziness or vertigo. Patients should be cautioned about operating machinery or driving if they experience these effects.
| Warfarin and other Coumarin Anticoagulants | Tinidazole may potentiate anticoagulant effect, increasing INR and bleeding risk. | Major |
| Alcohol and Alcohol-containing products | Disulfiram-like reaction with Tinidazole (flushing, tachycardia, nausea, vomiting). | Major |
| Phenobarbital, Phenytoin | May increase metabolism of Tinidazole, reducing its efficacy. | Moderate |
| Lithium | Tinidazole may increase lithium serum levels, risk of toxicity. | Moderate |
| Cyclosporine | Clindamycin may increase cyclosporine levels. | Moderate |
| Neuromuscular blocking agents (e.g., Tubocurarine) | Clindamycin may enhance neuromuscular blockade. | Moderate |
| Other Vaginal Products (creams, douches) | May physically interfere with absorption or efficacy. Use at separate times. | Minor |
