Comparative evaluation of efficacy of 10% povidone iodine gel with 2% metronidazole and 1% ornidazole with 0.25% chlorhexidine gel as local drug delivery system in adjunt to nonsurgical periodontal therapy in chronic periodontitis: A randomized, single blind, split-mouth study

Background: Periodontitis is a multi-factorial chronic inflammatory disease of attachment apparatus of teeth with microorganisms playing a major role. To address periodontal disease various strategies have been adopted to target these periodonto-pathogens. Various antimicrobial drugs (systemic as well as local) are effectively used to control the disease. However due to various side effects ofsystemic administration of the drugs like gastro intestinal disturbances, development of resistant organisms, high dosage of the drug required, local delivery of the drug is a better option as the drug is directly delivered at the site of infection with minimum dosage and maximum response achieved thus eliminating all the undesired effects of the drug. Aim: To evaluate the efficacy of 10% povidone iodine with 2% metronidazole and 1% ornidazole with 0.25% chlorhexidine gel as local delivery systems for the reduction in the pocket depth, changes in CAL, gingival inflammation. Materials and methods: A total of 20 patients diagnosed with mild- moderate chronic periodontitis were divided into two groups in a split-mouth study design - Group I and Group II with each group containing 20 sites with probing depth of >5 mm, CAL ?3 mm. In Group I, 10% povidine-iodine gel with 2% metronidazole was delivered inside the pocket and Group II, 1% ornidazole with 0.25% chlorhexidine was used as a local delivery system in adjunct to scaling and root planning. In both groups, medications were delivered at weekly interval for a period of 4 weeks. Baseline and 4 weeks measurements were done and compared for probing pocket depth (PPD), clinical attachment levels (CAL) and gingival inflammation. Results: The results obtained were statistically analyzed. Both groups showed statistically significant improvements in terms of clinical parameters. However, there was statistically insignificant difference when compared between the two groups. The results clearly demonstrate that both povidone iodine with metronidazole and ornidazole with chlorhexidine are also useful in controlling the acute phase of the periodontal disease in adjunct to scaling and root planning (SRP). Conclusion: Both drugs when used as an adjunct to scaling and root planning enhances probing pocket depth reduction, change in clinical attachment levels and gingival inflammation in mild- moderate chronic periodontitis cases.

Comparative Evaluation of Ornigreat Gel and Placebo (Hexigel 0.25%) as a Local Drug Delivery System in Association with Scaling and Root Planing in Patients with Chronic Periodontitis – An In vivo Study

Aim: The aim of the study was to evaluate the comparative effect of Ornigreat gel and Hexigel as a local drug delivery system in association with scaling and root planing (SRP) in patients with chronic periodontitis. Materials and Methods: A double-blind trial was conducted to test the comparative efficacy of the two commercially available Ornigreat gel and Hexigel at Indira Gandhi Govt. Dental College and Hospital, Jammu. These indices were recorded at baseline (“0 day”), 15th day, 30th day, 60th day, and 90th day in 40 sites, >4 mm pockets in 11 patients among which 20 sites received Ornigreat gel and other 20 sites receive Hexigel following SRP were compared. Results: The results of the study showed that the combination of SRP and Ornigreat gel therapy was more effective in reducing the mean values of gingival index and sulcus bleeding index though not statistically significant, but the values of plaque index showed statistical significance on the 60th day and 90th day, and the probing pocket depths showed statistically significant difference from the 15th day to the 90th day at P < 0.05 in comparison with Hexigel. Conclusion: The Ornigreat gel could be an efficient local drug delivery system when used in adjunct to SRP in comparison with Hexigel.

Synthesis And Biological Evaluation Of Thiosemicarbazone Analogues Of Ornidazole As Antifungal Agents

To synthesize a series of ornidazole thiosemicarbazone analogues on the basis of literature reviews of 2-Methyl-5-nitroimidazoles and thiosemicarbazones and to evaluate all the analogues in vitro for their activity against Aspergillus niger and fumigatus. Thiosemicarbazone analogues were synthesized from oxidising ornidazole with potassium dichromate and refluxing the oxidised product with substituted thiosemicarbazide using ethanol as solvent in the acidic medium overnight. All the synthesized analogues of ornidazole showed good antifungal action against fumigatus and niger except compound C-4. Unsubstituted amine analogue C-2 has shown highest percentage inhibition (96.6%, 500 μg/ml) against fumigatus while aromatic amine with or without electronegative atom analogues C-3 and C-5 has shown highest activity against Aspergillus niger which is two times than standard drug ornidazole (100%, 1000 μg/ml).

A Simple Liquid Chromatographic Method For Simultaneous Estimation Of Azithromycin, Fluconazole And Ornidazole In Bulk And Pharmaceutical Dosage Forms

Objective: The objective of the study was to develop and validate a new rapid and more sensitive Reverse Phase High-Performance Liquid Chromatography (RP-HPLC) method for the simultaneous estimation of azithromycin, fluconazole and ornidazole in bulk and pharmaceutical dosage forms. Methods: Separation was achieved with a cap cell pack C18 column (4.6 x 250 mm, 5μ) with an isocratic mobile phase containing a mixture of acetonitrile and phosphate buffer pH 4.8 [adjusted with ortho-phosphoric acid] (50:50 % v/v) at the flow rate of 1 ml/min and detection was monitored at 210 nm. Results: The retention time (Rt) of azithromycin, fluconazole and ornidazole were found to be 4.82±0.01, 5.25±0.01 and 6.33±0.01 min respectively. The precision was found with<1.5% of %RSD. The calibration curve was linear over the concentration ranging from 500-1000 µg/ml for azithromycin, 75-150 µg/ml for fluconazole and 375-750 µg/ml for ornidazole with the correlation coefficient (r2) of 0.999. The percentage recovery was found to be within the specified range i.e., 98-102 % for three drugs. Limit of detection (LOD) was found to be 5.810, 1.790 and 4.924 µg/ml, whereas Limit of quantification limits (LOQ) was found to be 9.834, 2.667 and 7.980 µg/ml, respectively. Conclusion: A simple isocratic liquid chromatographic method was developed and validated for simultaneous estimation of azithromycin, fluconazole and ornidazole in their formulations. Due to its simplicity, rapidness and specificity, it can be applied for routine quality control analysis of these drugs.

Objective: To study the therapeutic effect of compound Chinese medicine preparation of wild chrysanthemum and rhizoma drynariae combined with ornidazole in the treatment of chronic periodontitis, to explore the curative effect of this method in the treatment of chronic periodontitis, and to calarify its mechanism. Methods: A total of 112 patients with chronic periodontitis were divided into control group, ornidazole group, Chinese medicine group, Chinese medicine combined with ornidazole group (combination group) according the order of clinic time; there were 28 cases in each group. After basic periodontal treatment of the affected tooth (supragingival scaling and subgingival scaling), the periodontal pockets of the patients in control group were washed with 3% H2O2 and 0. 9%NaCl injection by turns, once a week; the patients in ornidazole group were orally administered with ornidazole one piece at a time, twice a day; the patients in Chinese medicine group were injected with compound Chinese medicine preparation of wild chrysanthemum and rhizoma drynariae into the pocket to make the medicine overflow to the edge of the gingival margin, once a week; the patients in combination group were injected with compound Chinese medicine preparation into the periodontal pocket while orally administered with ornidazole. All patients in various groups were treated for 4 weeks. The periodontal indexes including modified plaque index (mPLI), modified sulcus bleeding index (mSBI), probing depth (PD), and attachment loss (AL) of the patients in various groups were observed before and after treatment; and the levels of tumor necrosis factor-α (TNF-α) and prostaglandin E2 (PGE2) in the gingival crevicular fluid (PISF) of the patients in various groups were detected after one course of treatment. Results: There were no significant differences in the periodontal indexes and the levels of TNF-αand PGE2 in PISF of the patients before treatment between various groups (P>0. 05). Compared with control group, the level of PGE2 in PISF in Chinese medicine group was reduced (P0. 05); the mPLI, mSBI, PD and AL, the TNF-α level in PISF of the patients in combination group were significantly reduced (P<0. 05). Compared with Chinese medicine group, the mPLI, mSBI, PD and AL, the levels of TNF-α and PGE2 in PISF of the patients in combination group were significantly reduced (P<0. 05). Conclusion: The traditional compound Chinese medicine preparation of wild chrysanthemum and rhizoma drynariae combined with ornidazole has the best therapeutic effect in the chronic periodontitis, which can improve the periodontal index and reduce the levels of TNF-α and PGE2 in PISF of the patients.

A randomised double blind placebo controlled trial to assess the efficacy and tolerability of short course of ornidazole in diarrhoea predominant irritable bowel syndrome

Background: Irritable bowel syndrome is a common disorder affecting the general population. At present the treatment is mainly symptomatic as the pathophysiology is not clear. Abnormal flora especially small bowel bacterial over growth is considered as one of the causes. A short course of ornidazole is compared with placebo to assess its efficacy and tolerability in diarrhoea predominant irritable bowel syndrome.Methods: This was a randomised double-blind placebo controlled trial done in the Departments of Gastroenterology and Pharmacology at Government Medical College, Calicut. Patients were randomly assigned to two groups to receive either ornidazole or Placebo. The baseline symptoms were recorded and graded to get a global symptom score. Patients assigned to ornidazole group received 500mg twice daily orally for 5 days and the control group received identical looking placebo tablets. The patients were reassessed every week for four weeks. The patients subjective global assessment of relief and global symptom score was recorded. Statistical analysis was done using Wilcoxon signed Rank test and Mann Whitney U test.Results: This study was done in twenty patients with a mean age of 30 with comparable baseline characteristics and symptom scores (p=0.969). Ornidazole produced a highly significant reduction in the global symptom score (p<0.001) compared to placebo. It was maintained through the four weeks follow up. No serious adverse effects were reported. Two patients reported burning sensation in the stomach which was self limited.Conclusions: Ornidazole is efficacious than placebo in controlling the symptoms of diarrhoea predominant irritable bowel syndrome and is well tolerated.

A fixed dose combination of ofloxacin and ornidazole induced fixed drug eruptions

Fixed drug eruptions (FDEs) may account for 16-21% of all cutaneous drug eruptions. Recent research suggests a cell-mediated process that initiates both the active and quiescent lesions. The major categories of causative agents of fixed drug eruption include antibiotics, antiepileptics, nonsteroidal anti-inflammatory agents, sildenafil, and phenothiazines, although numerous other agents and certain foods such as cashews and licorice have also been reported as causative agents. A 38 year old male presented to the dermatology OPD with hyperpigmented and erythematous macular eruptions on the neck, chest, right arm, left scapular region, left wrist and left knee. The eruptions were associated with burning sensation and itching. He informed having taken medications for gastroenteritis the night before. The medications were Ofloxacin and Ornidazole (FDC), Omeprazole and Domperidone (FDC) and Paracetamol. He gave a history of a similar event, a year ago, with the same antimicrobial combination (Ofloxacin and Ornidazole), although the macular eruptions were restricted to the neck, arm and knee with bleb formation and severe burning sensation. Since the macular eruptions reoccurred, although with extra regions being affected, a diagnosis of FDEs was made. The most probable cause for these FDEs seems to be FDC of Ofloxacin and Ornidazole, because the patient gives history of taking Omeprazole and Paracetamol before without any FDEs. According to Naranjo’s Adverse Drug Reaction Probability Scale, the FDC of Ofloxacin and Ornidazole is a definite cause for the FDEs. (Score = 9).

Development and Evaluation of In-Situ Gel Containing Ornidazole Loaded Microspheres for Treatment of Periodontitis.

The present investigation aims at developing novel injectable in-situ gel containing ornidazole (ORDZ) loaded chitosan microspheres for treatment of periodontal disease. Microspheres were prepared by emulsification-ionotropic gelation method. Prepared microspheres were evaluated extensively for particle size, equilibrium swelling studies, bioadhesion, percentage drug release and antimicrobial activity. The mean diameter of the microspheres was found in the range of 29.1-52.65 µm. The microspheres showed good swelling properties. Percentage equilibrium swelling was dependent upon the amount of chitosan. The in vitro drug release and bioadhesion studies were dependent on the extent of crosslinking and chitosan concentration. The ORDZ–loaded microspheres showed drug encapsulation in the range of 11.02±0.98 - 32.45±0.62 % and sustained the release up to 5 days. The drug release from microspheres was diffusion controlled. The antimicrobial study indicated inhibition of growth of Staphylococcus aureus at all drug concentrations of in vitro release samples. In situ gel containing optimized microspheres extended the drug release up to 7 days. Results of the study demonstrated good bioadhesion of the in-situ gel containing microspheres as well as exhibited sustained release of drug. The in-situ gel containing ORDZ- loaded chitosan microspheres may be an efficient alternative to the other known delivery systems for treatment of Periodontitis.

OBJECTIVE: To investigate the clinical use of ornidazole injection in a wide patient population by the post-marketing hospital centralized monitoring method in order to regulate and guide its rational use, improve the drug specification, and provide a basis for the drug therapy. METHODS: A prospective, multi-center, large sample hospital centralized monitoring method was adopted. Five sentinel hospitals in Hubei Province were selected, and hospitalized patients who received ornidazole injection treatment from July 1, 2015 to October 31, 2015 were observed. The basic information of the patients was recorded, as well as the drug use and adverse events, and then statistical analysis was made. RESULTS: A total of 4396 cases were enrolled in this study, most of them were middle-aged female patients. Ornidazole injection was mainly used before surgeries to prevent infections and after surgeries for treatment of anaerobic infections, abdominal infections and pelvic infections. Irrational drug use existed in clinic, mainly concentrating at unreasonable dosing frequency, excessive dripping speed, and long duration of use. Eleven cases of adverse reactions were collected during the monitoring, indicating an incidence of adverse drug reactions of 2.5‰, and most of the adverse drug reactions occurred within 30 min post drug administration. CONCLUSION: The manufacturers should make further investigation on the dripping speed and quality standard of ornidazole injection to further improve the information in the package insert and regulate the clinical use.

Analysis of the Correlation between Ornidazole Salivary Concentration and Plasma Concentration / 中国药房

OBJECTIVE:To explore the correlation between ornidazole (ONZ) salivary concentration and plasma concentra-tions in healthy subjects,and to provide reference for clinical therapeutic drug monitoring. METHODS:24 healthy volunteers were selected. After oral administration of ONZ capsules 1.00 g,their venous blood and saliva were collected at 0.25,0.5,1.5,5.5, 10.5,24.5 and 43.5 h after medication. HPLC method was used to determine the plasma and salivary concentrations of ONZ. The correlation between the two was analyzed. RESULTS:The peak values of plasma and salivary ONZ concentrations appeared imme-diately at 1.5 h after administration and the peak values were(0.96±0.15)μg/ml and(0.93±0.15)μg/ml;salivary concentration of ONZ was lower than plasma concentration at each time points,but there was no statistical significance (P>0.05);the regres-sion equation of salivary ONZ concentration and plasma concentration was csaliva=1.176 5cplasma-0.199 4(r=0.990 1). The ratio of salivary concentration and plasma concentration of ONZ (S/P) was (0.91 ± 0.06),showing positive correlation (r=0.632-0.970, P<0.05). CONCLUSIONS:The salivary ONZ concentration is significantly correlated with plasma concentration in healthy peo-ple,so saliva can be used for therapeutic drug monitoring.

RESULTS:The linear range were 1-100μg/ml for both ornidazole(r=0.999 7)and dexamethasone sodium phosphate(r=0.999 9);RSDs of precision,stabili-ty and reproducibility tests were lower than 2.0%;recoveries were 96.50%-99.80%(RSD=1.02%,n=9) and 96.50%-99.60%(RSD=0.99%,n=9). CONCLUSIONS:The method is specific with good precision and stability and high accuracy,and can be used for the simultaneous determination of ornidazole and dexamethasone sodium phosphate in Compound ornidazole film.

Clinical effect of combination therapy of ornidazole and pefloxacin on chronic periodontitis / 中国基层医药

Objective To evaluate combination therapy effects of ornidazole and pefloxacin on chronic periodontitis.Methods 200 cases of chronic periodontitis were chosen from the Stomatological Hospital of Hangzhou as study subjects.100 cases in observation group were treated with ornidazole and pefloxacin combination treatment, while another 100 cases in control group were treated with ornidazole.The treatments lasted 7 days.The effects and inflammation -related perimeters (including hs -CRP,IL -4,IL -6,IFN -γ)in patients'serum were measured. Results Probing depth,attachment loss and inflammation -related perimeters of the observation group were improved significantly,and even were much better than the control group (probing depth:t =2.113,P <0.05;attachment loss:t =1.894,P <0.05,hypersensitive C -reactive protein:t =2.001,P <0.05;IL -6:t =1.953,P <0.05;interferon -γ:t =1.976,P <0.05).And the total effective rate of the observation group was also better than that of the control group (χ2 =24.335,P <0.01).Conclusion Combination treatment of ornidazole and pefloxacin is more effective than single treatment of ornidazole,which is worthy of widely promoted in clinical.

Comparison of the clinical effect of ornidazole and metronidazole in the treatment of trichomonal vaginitis / 中国基层医药

Objective To observe and compare the clinical efficacy of ornidazole and metronidazole in the treatment of trichomonal vaginitis.Methods We selected 64 patients with trichomonal vaginitis who were treated in our hospiatl from January 201 3 to December 201 4,and they were divided into the observation group and the control group,each group had 32 cases.The observation group was treated with ornidazole,while the control group was treated with metronidazole.The clinical efficacy,yellow leucorrhea,frequent urination,and other clinical symptoms and adverse reactions of the two groups were compared.Results The total effective rate of the ornidazole group was 96.875%,which of the metronidazole group was 81 .75%.The ornidazole group was significantly better than the met-ronidazole group,and there was significant difference (χ2 =6.869,P 0.05).After treatment,the clinical symptoms incindence:yellow leucorrhea,frequent urination,etc of the ornidazole group was significantly lower than those of the metronidazole group,and there were significant differences (χ2 =6.594,8.256,6.783,6.469,all P <0.05 ).The incidence of adverse reaction of the ornidazole group was significantly lower than that of the metronidazole group,and there was significant difference (χ2 =8.325,P <0.05).Conclusion The clinical efficacy of ornidazole for the treament of trichomonas vaginitis was significantly better than metronidazole,and the clinical symptoms improved more significantly, it has higher safety and worthy of clinical application.
