Clobetasol 500microgram / Neomycin 5mg / Nystatin 100,000units/g ointment

Erosive pustular dermatosis (EPD) is a chronic inflammatory skin disorder that usually affects mature individuals. It predominantly affects the scalp and can lead to scarring alopecia. Risk factors include actinic damage and androgenetic alopecia. A traumatic insult to the skin is considered a vital trigger of the condition. EPD is a diagnosis of exclusion; thus, several neoplastic, infectious, vesiculobullous, and inflammatory conditions should be ruled out. Biopsy and clinicopathologic correlation are required to differentiate between EPD and these entities. A dysregulated, chronic immune response is considered central to the etiopathogenesis of EPD. We performed an evidence-based systematic review of the management options. There were predominantly studies with level IV and V evidence and only two with level III. Despite the responsiveness of EPD to potent topical steroids, such as clobetasol propionate, recurrence occurs after treatment withdrawal. With the available data, tacrolimus 0.1%, curettage-assisted aminolevulinic acid-photodynamic therapy, and systemic retinoids can be considered second-line options for EPD with a role in maintenance regimens. However, controlled data and more powerful studies are needed to make solid recommendations.

Neomycin sulphate is official in IP 2018, USP 2004 and BP 2003; which includes Microbial assay (Cylinder Plate assay) for the estimation therefore chemical derivatization of Neomycin Sulphate is done using 1-Fluoro-2, 4-Dinitrobenzene (DNFB); also known as Sanger’s reagent, to make it detectable by UV with good accuracy and precision. A fixed dose combination of Neomycin Sulphate, Clobetasol Propionate and Chlorocresol (preservative) in cream formulation is used to treat different types of Skin infections. The literature review reveals that methods like UV, HPLC, HPTLC, GC-MS etc. have been reported for Neomycin Sulphate and Clobetasol Propionate individually and along with other drugs. But no reported method found in combination for Neomycin sulphate and Clobetasol propionate. A simple, accurate, precise and economical UV spectrophotometric i.e. Area Under Curve Method (AUC) was developed. All the dilutions of drugs were prepared in Methanol: Acetonitrile (50:50). Area under curve was integrated in the wavelength range of 235.0- 245.0 nm, 252.0-262.0 nm and 223.0-233.0 nm for CSP, NMS and CCS respectively. The AUC method for Clobetasol Propionate (CSP), Neomycin Sulphate (NMS) and Chlorocresol (CCS) was found to be linear over the range of 0.8-1.2 μg/ml, 8.0-12.0 μg/ml and 1.6-2.4 μg/ml respectively. The result of analysis was analysed and validated statistically and recovery study was found within range of 98-102%. The % RSD was not more than 2.0 % which indicates good precision. All the validation parameters were carried out according to ICH Q2 (R1) guidelines.

Background/Objectives: Aerobic vaginitis (AV) and bacterial vaginosis (BV) are vaginal infections requiring the fast elimination of pathogens. The frequent confusion of these infections may justify the use of a rapidly acting broad-spectrum antibiotic treatment. Methods: This study investigated the bactericidal kinetics of the neomycin-polymyxin B-nystatin (NPN) combination compared to those of two reference antibiotics (clindamycin and metronidazole) against 22 bacteria commonly implicated in AV and BV. Results: NPN exhibited bactericidal activity against the aerobic Gram-positive bacteria, with particularly high bactericidal activity being observed against streptococci, S. aureus, and C. amycolatum after 1 h at low dilutions and after 4 h for all dilutions. Enterococci were less sensitive to NPN. Clindamycin demonstrated poor rapid bactericidal activity against all Gram-positive bacteria tested. NPN manifested high bactericidal activity against all aerobic Gram-negative bacteria tested, whereas clindamycin showed bactericidal activity only after 4 h at a 1/2 dilution. With respect to the four anaerobic strains tested, NPN demonstrated high bactericidal activity at all tested dilutions with concentration-dependent effects. Metronidazole exhibited lower or no rapid bactericidal activity. Conclusions: These results suggest that NPN has very fast bactericidal action against the main bacteria involved in AV and BV compared to clindamycin and metronidazole, highlighting its potential in managing bacterial vaginal infections.

The aim of study is production of new local drug consisting of Nystatin, Neomycin sulfate, Dexamethasone ointment are veterinary medicinal preparations used in the treatment of exogenous fungi and infections in small and large animals that cause by (candida albicans) and affected by gram positive and gram negative bacteria like (Staphylococcus aureus, Escherichia coli, Haemophilus influenza, Klebsiella-Enterobacter species, Neisseria species, and Pseudomonas aeruginosa). Nystatin is considered one of the safe drugs when treating external fungal infections in field animals. Neomycin works by inhibiting protein synthesis in the bacterial cell and thus leads to the killing of bacteria either dexamethasone works to stop infections in the affected area of ​​animals. In order for this product to be both research and applied, many of the initial pharmaceutical compositions were prepared until the final and stable composition was reached in this form. (90-110% permissible limit of activity). This process included several stages of collecting information on the substances included in the formula, active substances and additives, and then preparing the formula according to the specifications. International pharmacology using pharmacopoeia, followed by a study of stability and resistance of the preparation at room temperatures, then sending samples for field examination to the veterinary department and for the lack of cases for other animals where it was used on cases of fungal infections and skin infections in small animals (Cats). The treatment period was 5-10 days, and it brought very good results, according to the field evaluation form attached to the research. Outcomes of study its good and new research and very important to treatment skin infection in small animals.

Background. Atopobium vaginae is an important component of the complex abnormal anaerobic vaginal microflora in vaginal dysbiosis and is believed to be at least partially responsible for known adverse gynecological and obstetric outcomes. Resistance of A. vaginae to traditional therapy (metronidazole and clindamycin) is described.Objective of the study: to evaluate the effectiveness of topical therapy with the combined drug ternidazole–neomycin sulfate–nystatin–prednisoloneof vaginal dysbiosis associated with A. vaginae in diagnostically significant concentrations in non-pregnant and pregnant women of reproductive age with a history of reproductive failure.Materials and methods. 78 women of reproductive age with vaginal dysbiosis associated with A. vaginae in diagnostically significant concentrations were under observation. 37 infertile women had recurrent implantation failures and 41 pregnant women with infertility treated in cycles of assisted reproductive technologies. Control groups consisted of 30 fertile non-pregnant women and 30 pregnant women after natural conception with vaginal normocenosis. Comprehensive quantitative assessment of the vaginal anaerobic microbiota was performed using real-time polymerase chain reaction.Results. A. vaginae in diagnostically significant concentrations in the vaginal microbiota in the vast majority of cases is accompanied by the presence of Gardnerella vaginalis and other co-pathogens, mixed infections. Every second woman has aerobic-anaerobic dysbiosis, which makes it advisable to use combined topical drugs. The use of ternidazole–neomycin sulfate–nystatin–prednisolone vaginal tablets resulted in the absence of facultative and obligate anaerobes, Ureaplasma (urealiticum + parvum) and Candida spp. in the vaginal microbiota in diagnostically significant concentrations in women of treated groups. The average relative content of none of the studied conditionally pathogenic microorganisms after treatment did not exceed -3 CFU.Conclusions. The combined vaginal drug ternidazole–neomycin sulfate–nystatin–prednisolone is a highly effective, safe and compliant remedy for restoring vaginal health in non-pregnant and pregnant women with a history of reproductive failure and vaginal dysbiosis associated with the presence of A. vaginae in diagnostically significant concentrations.
