Cost-Effectiveness Analysis of Metronidazole versus Metronidazole with Diloxanide furoate in the Treatment of Amoebiasis in Ethiopia
Clinicoecon Outcomes Res 2021 Jul 1;13:611-617.PMID:34234483DOI:10.2147/CEOR.S312821.
Introduction: Amoebiasis is one of the world's most prevalent and fatal infectious diseases. Several surveys revealed that amoebiasis is one of the most widely distributed diseases in Ethiopia. The combination of metronidazole with Diloxanide furoate represents a new approach for the treatment of the infection. Objective: This study aimed to analyze the cost-effectiveness of diloxanide plus metronidazole compared with metronidazole alone in the treatment of amoebiasis in Ethiopia. Methods: An analytical decision model was used to analyze costs and effectiveness from a societal perspective by taking adult amoebic patients as the study population with a time horizon of two months. The potential impacts of uncertainty in single parameters were explored in one-way sensitivity analyses. Results: Metronidazole with diloxanide had a higher cost and effect compared to metronidazole alone with an incremental cost-effectiveness ratio (ICER) of 8 US$ per amoebic case cured. The result was sensitive to the decrease in the effectiveness of metronidazole with diloxanide. Conclusion: This study revealed the addition of diloxanide to standard treatment to be a more effective and more costly treatment strategy. Therefore, a decision for choosing the medication should be based on the ability of patients to pay for the treatment.
Diloxanide furoate binary complexes with 尾-, methyl-尾-, and hydroxypropyl-尾-cyclodextrins: inclusion mode, characterization in solution and in solid state and in vitro dissolution studies
Pharm Dev Technol 2018 Sep;23(7):723-731.PMID:28758845DOI:10.1080/10837450.2017.1362435.
The purpose of this study was to investigate the effect on solubility and dissolution rate of binary complexes of 尾-(尾CD), methyl-(M尾CD) and hydroxypropyl-尾-cyclodextrin (HP尾CD) with Diloxanide furoate (DF). The complexation in solution was evaluated by phase solubility studies and 1H nuclear magnetic resonance (NMR). Enhanced water solubility of DF was obtained with the DF:M尾CD system (61-fold). The mode of inclusion was supported by NMR experiments, which indicated that real inclusion complexes were formed between DF and M尾CD or HP尾CD. Solid state analysis was performed using infrared and thermal methods, which suggested the formation of true inclusion complexes of DF with two derivatized cyclodextrins, M尾CD and HP尾CD, and an exclusion complex with 尾CD when the systems were prepared by freeze-dried technique. Dissolution studies conducted in simulated gastric fluid (2 h) and subsequent simulated intestinal fluid (next 4 h) showed increased dissolution rate of DF from the freeze-dried systems with 尾CD, M尾CD, and HP尾CD (85; 77 and 75% of dissolved drug at 5 min, respectively) and 100% of the drug dissolved at 150 min for the three systems. The enhancement of the solubility and the dissolution of DF observed make these complexes promising candidates for the preparation of oral pharmaceutical formulations.
Diloxanide furoate for treating asymptomatic Entamoeba histolytica cyst passers: 14 years' experience in the United States
Clin Infect Dis 1992 Sep;15(3):464-8.PMID:1520794DOI:10.1093/clind/15.3.464.
Diloxanide furoate is used for treating asymptomatic or mildly symptomatic persons who are passing cysts of Entamoeba histolytica. The Centers for Disease Control (Atlanta) released this drug for 4,371 treatment courses from 1977 through 1990. Of the 2,815 report forms (64%) returned, 656 adverse effects were reported for 390 treatment courses (14%); they included flatulence (260), diarrhea or cramping (100), nausea (93), headache (17), disorientation or dizziness (9), and diplopia (4). During 1984-1990 uniform collection of data allowed more detailed analysis of toxicity and efficacy; fewer adverse effects were reported for persons aged 20 months to 10 years than for persons aged greater than 10 years (6 of 206 [3%] vs. 89 of 763 [12%], relative risk = 0.27, 95% confidence interval = 0.12 less than relative risk less than 0.61). Parasitological cures were achieved during 497 (86%) of the 575 treatment courses (52%) administered to asymptomatic persons who were passing cysts, who had received a full 10-day treatment course, and for whom results of a follow-up stool examination (greater than or equal to 14 days post-treatment) were available. Diloxanide furoate is safe and effective for treating asymptomatic persons who are passing E. histolytica cysts and may be particularly well tolerated in children.
Simultaneous determination of Diloxanide furoate and metronidazole in presence of Diloxanide furoate degradation products
J AOAC Int 2011 Sep-Oct;94(5):1427-39.PMID:22165007DOI:10.5740/jaoacint.10-286.
Three methods are presented for the simultaneous determination of Diloxanide furoate (DLX) and metronidazole (MTR), used for their antiprotozoal and antiamoebic effect, in the presence of DLX alkaline degradates and in pharmaceutical formulations, without previous separation. The first method is chemometric-assisted spectrophotometry, in which principal component regression and partial least squares were applied. These two approaches were successfully applied to quantify each drug in the mixture using the information included in, the absorption spectra in the range of 225-320 nm. The second method is TLC-densitometry, in which the binary mixture and degradates were separated on silica gel plates using a chloroform-acetone-glacial acetic acid (9.5 + 0.5 + 0.07, v/v/v) mobile phase and the bands were scanned at 254 nm. The last method is HPLC, in which DLX, MTR, and degradates were separated using the mobile phase acetonitrile-0.05 M dibasic potassium phosphate (25 + 75, v/v), adjusted to pH 4 with orthophosphoric acid, at a flow rate of 1 mL/min, on a C18 analytical column. Detection was at 254 nm. The proposed methods were successfully applied for the analysis of DLX and MTR in pharmaceutical formulations, and the results were statistically compared with a reported spectrophotometric method.
Enhancement of site specific delivery of Diloxanide furoate as an antiamoebic drug
Eur J Pharm Sci 2016 Apr 30;86:50-7.PMID:26952868DOI:10.1016/j.ejps.2016.03.001.
The basic aim of the present research work is to deliver the Diloxanide furoate (DF) at specific area using pectin microspheres. The microspheres were prepared by spray drying method and cross-linked by zinc acetate. Different concentrations of polymer (pectin 0.5-3%) and cross-linking agent (0-3% w/v in a mixture of ethanol:water) are taken to optimize the entrapment efficiency, swelling behavior, size and first 6h in-vitro release in simulated gastric fluids. Optimized formulation was characterized in the terms of in-vitro release, in-vivo drug disposition in various organs and in the blood of Sprague-Dawley albino rats and in-vivo gastrointestinal tract transit behavior using X-ray imaging method on albino rabbits. Findings suggested that microspheres containing a concentration of polymer (2% w/v) have average size of 100-500 渭m, entrapment efficiency 85.82 卤 0.5 with swelling index 18.77 卤 5.21. In-vitro results and in-vivo gastric transit behavior (using X-ray imaging) have shown no release in first 3-6h that proved the colon specific delivery of DF. The results also suggested that the above approach have not only site specific delivery, but it improves the conversion of active drug by increasing the enzyme mediated hydrolytic degradation of DF due to the presence of polysaccharide polymer:water gel complex.
