Cell experiment: | MRSA clinical isolates are used in this study and the MIC50 for Robenidine (compound 1) is determined using a modified MIC assay. The antimicrobial dilutions of Robenidine are completed in 100% DMSO, with 2 μL added to each well. The assay is performed in a total volume of 200 μL in 96-well plates. Robenidine is tested in final concentrations of 0.7 to 345.3 μM. Plates are incubated for 20 to 24 h at 37°C before determination of the MIC[1]. |
Animal experiment: | The rabbits are divided into four groups (n=8, each group). The rabbits in the control group are fed anticoccidial-free rations throughout the study. Rabbits in the other group are fed rations containing Robenidine (ROB) (66 ppm) for 20 consecutive days. At the end of the 20th day of feeding, a single dose of Florfenicol (FFC) is injected intravenously at 25 mg/kg body weight (b.w.) into the left auricular vein of each rabbit in all groups. Blood (approximately 1 mL) samples are collected into heparin-coated tubes from the right auricular vein of each rabbit at 5, 10, 15, 30, and 45 min and 1, 1.5, 2, 4, 6, 8, and 12 h after administration of FFC. The plasma is harvested after centrifugation at 3,000 g for 10 min and stored at -20°C until analysis[2]. |

Safety and efficacy of Robenz® 66G (Robenidine hydrochloride) for chickens for fattening and turkeys for fattening
EFSA J2019 Mar 5;17(3):e05613.PMID:32626244DOI:10.2903/j.efsa.2019.5613.
Following a request from European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of Robenz® 66G (Robenidine hydrochloride (HCl)) when used as a feed additive for chickens for fattening and turkeys for fattening. The coccidiostat Robenz® 66G is considered safe for chickens for fattening at the highest proposed level of 36 mg robenidine HCl/kg complete feed with a margin of safety of approximately 2.5. This conclusion is extrapolated to turkeys for fattening. Robenidine HCl is active against Gram-positive but not against Gram-negative bacteria. It is not expected that the use of robenidine HCl as a feed additive would induce resistance or cross-resistance to antimicrobials used in human and animal therapy. The use of robenidine HCl from Robenz® 66G at the highest proposed level of 36 mg/kg complete feed in chickens and turkeys for fattening is considered safe for the consumer. The existing maximum residues limits for both avian species are confirmed. Robenidine HCl is not a skin or eye irritant and not a skin sensitiser. The risk via inhalation is considered negligible. The use of robenidine HCl from Robenz® in feed for chickens for fattening and turkeys for fattening up to 36 mg/kg complete feed does not pose a risk to either the terrestrial or the aquatic compartment. A risk for bioaccumulation cannot be excluded. The risk for secondary poisoning is not likely to occur. The FEEDAP Panel concludes that 36 mg robenidine HCl/kg complete feed from Robenz® 66G has the potential to effectively control coccidiosis of chickens for fattening under field conditions but cannot conclude on the efficacy of robenidine HCl in turkeys for fattening. The existing 5-day withdrawal period to avoid off-flavours in edible tissues should be maintained.
Assessment of the feed additive consisting of Robenidine hydrochloride (Cycostat® 66G) for rabbits for breeding and rabbits for fattening for the renewal of its authorisation (Zoetis)
EFSA J2023 Mar 9;21(3):e07863.PMID:36908564DOI:10.2903/j.efsa.2023.7863.
Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the feed additive consisting of Robenidine hydrochloride (Cycostat® 66G) for rabbits for breeding and rabbits for fattening for the renewal of its authorisation. Since the potential aneugenic activity of Robenidine hydrochloride cannot be excluded, the FEEDAP Panel is not in the position to conclude on the safety of the additive for the target species and the consumer. In the absence of data, the FEEDAP Panel cannot conclude on the safety of Robenidine hydrochloride for the environment. Robenidine hydrochloride has potential for bioaccumulation; however, a risk for secondary poisoning for worm/fish-eating birds and mammals is not likely to occur. No concern for groundwater is expected. Robenidine hydrochloride is not a skin or eye irritant and not a skin sensitiser. Due to the lack of data on the genotoxicity (aneugenicity) of the substance, the exposure to the additive of the unprotected users should be minimised. Owing to the lack of sufficient data, the FEEDAP Panel cannot conclude that Robenidine hydrochloride from Cycostat® 66G is still efficacious against recent Eimeria spp. strains in rabbits.
Determination of robenidine in shrimp and chicken samples using the indirect competitive enzyme-linked immunosorbent assay and immunochromatographic strip assay
Analyst2021 Jan 21;146(2):721-729.PMID:33231576DOI:10.1039/d0an01783c.
In this study, the monoclonal antibody-based indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) and an immunochromatographic strip assay were developed for the rapid screening of Robenidine hydrochloride (ROBH) in samples. The 50% inhibitory concentration (IC50) of ROBH was 0.927 ng mL-1, and the standard curve showed a linear correlation coefficient of 0.99932. There was no cross-reaction between ROBH and other commonly used anticoccidial drugs, which indicated that the monoclonal antibody had high specificity. The recoveries of ic-ELISA were in the range of 87.8% to 102.0%. The immunochromatographic strip assay displayed cut-off values of 10, 5 and 10 ng g-1 for shrimp, chicken breast and chicken liver samples, respectively. In addition, the results can be obtained within 10 min by naked eye observations. And in sample analysis, the results of ic-ELISA and the immunochromatographic strip assay were in accordance with those of LC-MS/MS. Thus, the ic-ELISA and immunochromatographic strip assay are effective methods for the detection of ROBH in shrimp, chicken breast and chicken liver samples.

Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of BIO-THREE® when used as a feed additive for chickens for fattening, chickens reared for laying, turkeys for fattening, turkeys reared for breeding, all avian species for rearing/fattening to slaughter and all avian species reared for laying or breeding to point of lay. The product under assessment is based on viable cells/spores of Bacillus subtilis FERM BP-07462, Enterococcus lactis FERM BP-10867 and Clostridium butyricum FERM BP-10866. Based on the tolerance study provided, the Panel concluded that the additive is safe for the target species under the conditions of use. The additive is safe for the consumers of products derived from animals receiving the additive. The additive is not irritant to skin and eyes. The additive is a respiratory sensitiser. No conclusions could be drawn on its potential to be a skin sensitiser. The use of the product as a feed additive is of no concern for the environment. The FEEDAP Panel was not in the position to conclude on the efficacy of BIO-THREE® for the target species. BIO-THREE® is compatible with diclazuril, decoquinate and halofuginone. No conclusions could be drawn on the compatibility of BIO-THREE® with monensin sodium, salinomycin sodium, narasin, Robenidine hydrochloride and maduramicin ammonium.
Automated high-pressure liquid chromatographic assay of Robenidine hydrochloride
J Assoc Off Anal Chem1975 Jul;58(4):822-7.PMID:1150616doi
High-pressure liquid chromatography has been applied to the separation and analysis of Robenidine hydrochloride in the presence of its chemical precursors. It provides a rapid and specific method for the analysis of robenidine in technical material as well as feed premixes and is capable of distinguishing the intact drug from its degradation products. The chromatographic system employs a mixture of methanol, acetic acid, and methylene chloride as the mobile phase and a controlled pore glass as the stationary phase. Sample manipulation has been automated in 2 ways. In the first, manually prepared samples are automatically injected onto the column for separation and quantitation. In the second, a totally automated sample handling system, weighed samples are extracted, diluted, filtered, and then injected onto the column, all in a sequential manner. These procedures are capable of giving quantitative results at a rate of 10 samples/hr with a relative standard deviation of 1.13%.
