Abstract
Abstract
Background
The combined mixture of miconazole nitrate (MIC) and nystatin (NYS) has proven its efficiency as a prodigious remedy to cure women’s frequent infections: vaginal mycosis and vaginal candidiasis.
Objective
A novel green spectrophotometric technique, namely the Fourier self-deconvolution method (FSD), was employed for the quantitative determination of MIC and NYS in their pure and pharmaceutical forms without prior separation. Moreover, the proposed technique was first employed to study the dissolution profile of the cited drugs in their pharmaceutical formulation according to FDA recommendations without excipient interference.
Method
The FSD method is based on a simple mathematical manipulation of zero-order spectra of the cited drugs, which suffered from severe overlapping, so zero-order spectra of the cited drugs were deconvoluted using the Fourier wavelet function in spectrophotometer software. The deconvoluted amplitudes for MIC and NYS were measured at 255 nm and 320 nm, respectively.
Results
Linearity ranges were 70–700 µg/mL for MIC and 1–25 µg/mL for NYS. The greenness of the proposed technique was assessed using two assessment tools, namely eco-scale scoring and green analytical procedure index (GAPI), revealing the excellent greenness of this technique. The proposed technique was validated consistent with ICH guidelines and statistically compared to the reported method with no significant differences between them.
Conclusions
The proposed technique has advantages of being simple, time-saving, and noting need any modification to be suitable for quantitative analysis of MIC and NYS in both pharmaceutical and laboratory mixtures.
Highlights
An innovative FSD method was developed for quantitative analysis of MIC and NYS in their synthetic and pharmaceutical mixtures and applied for in vitro dissolution testing of their pharmaceutical mixture, producing satisfactory results.

Abstract
Controlled-release tablets and rectal suppositories of sulfasalazine (SLF) and hydrocortisone 21-acetate (HA) were prepared as recommended dosage forms for the treatment of acute episodes of ulcerative colitis, in patients who do not respond to monotherapy. A High-Performance Liquid Chromatography (HPLC) Diode-array method with a gradient elution mobile phase was developed to evaluate the production quality of both formulations (assay and dissolution profiles in gastric and intestinal fluids). Method's validation was carried out providing good linearity (r ≥ 0.9995), precision (RSD < 1.53%), recovery (96.9% - 103.7%) and limits of detection (LODSLF = 12 ng/mL, LODHA = 15 ng/mL). Experimental design and Plackett-Burman methodology was constructed to study the robustness of the analysis. In all composite substrates, a freezing lipid precipitation approach was used as purification step. The method was optimized by applying Central Composite design mode. The in-vitro/ex-vivo permeability studies of both formulations were evaluated by a Liquid Chromatography-Electron Spray Ionization Mass Spectrometry (LC-ESI/MS) +/- mode. The analysis of sulfamethazine (internal standard, SLM, m/z 279), HA (m/z 449, [M + HCOO]-), SLF (m/z 399) and its active metabolite mesalazine (MSL, m/z 154) was performed using a C18 column and gradient elution. The validation of the method met the requirements of the International Council for Harmonization (ICH) (r ≥ 0.9997, RSD ≤ 4.62%, Recovery > 95%, LODSLF = 1.28 ng/mL, LODHA = 1.07 ng/mL, LODMSL = 3.16 ng/mL). Based on the results, important conclusions were drawn concerning the role of excipients and SLF metabolism.

Abstract
Miconazole nitrate (MIC) and nystatin (NYS) combination has proven its effectiveness as a prodigious therapy to cure women's common infections; vaginal candidiasis and vaginal mycosis. Herein, six smart UV-spectrophotometric platforms depending on minimal mathematical manipulation steps were first introduced for the simultaneous green analysis of MIC and NYS in their pure forms and commercial vaginal suppositories without any preliminary separation steps. These platforms included dual-wavelength, ratio difference, mean centering of ratio spectra, first derivative ratio, ratio subtraction, and absorption correction methods. All of the aforementioned platforms could estimate MIC in a linear range of 90-900 µg/ml. While NYS was computed directly by zero-order spectrophotometry at its λmax (304 nm) in a linear range of 1-15 µg/ml without any interference by MIC even in low or high concentrations. Dual-wavelength and zero-order spectrophotometric platforms were successfully applied to study the dissolution profile of MIC and NYS in their combined formulation in compliance with FDA recommendations without excipients interference. According to ICH guidelines, all platforms were validated regarding the accuracy, precision, and selectivity producing satisfactory results within the accepted limits. Also, the suggested platforms' results were statistically compared with each other and with those of the reported HPLC platform revealing no significant difference concerning accuracy and precision at p = .05. Accordingly, all proposed platforms are regarded as economic and eco-friendly alternatives to the expensive chromatographic platforms that utilize hazardous organic solvents during the analysis of cited drugs.

Abstract
Simultaneous determination of miconazole (MIC), mometasone furaoate (MF), and gentamicin (GEN) in their pharmaceutical combination. Gentamicin determination is based on derivatization with of o-phthalaldehyde reagent (OPA) without any interference of other cited drugs, while the spectra of MIC and MF are resolved using both successive and progressive resolution techniques. The first derivative spectrum of MF is measured using constant multiplication or spectrum subtraction, while its recovered zero order spectrum is obtained using derivative transformation. Beside the application of constant value method. Zero order spectrum of MIC is obtained by derivative transformation after getting its first derivative spectrum by derivative subtraction method. The novel method namely, differential amplitude modulation is used to get the concentration of MF and MIC, while the novel graphical method namely, concentration value is used to get the concentration of MIC, MF, and GEN. Accuracy and precision testing of the developed methods show good results. Specificity of the methods is ensured and is successfully applied for the analysis of pharmaceutical formulation of the three drugs in combination. ICH guidelines are used for validation of the proposed methods. Statistical data are calculated, and the results are satisfactory revealing no significant difference regarding accuracy and precision.

Abstract
This work presents the application of different spectrophotometric techniques based on two wavelengths for the determination of severely overlapped spectral components in a binary mixture without prior separation. Four novel spectrophotometric methods were developed namely: induced dual wavelength method (IDW), dual wavelength resolution technique (DWRT), advanced amplitude modulation method (AAM) and induced amplitude modulation method (IAM). The results of the novel methods were compared to that of three well-established methods which were: dual wavelength method (DW), Vierordt's method (VD) and bivariate method (BV). The developed methods were applied for the analysis of the binary mixture of hydrocortisone acetate (HCA) and fusidic acid (FSA) formulated as topical cream accompanied by the determination of methyl paraben and propyl paraben present as preservatives. The specificity of the novel methods was investigated by analyzing laboratory prepared mixtures and the combined dosage form. The methods were validated as per ICH guidelines where accuracy, repeatability, inter-day precision and robustness were found to be within the acceptable limits. The results obtained from the proposed methods were statistically compared with official ones where no significant difference was observed. No difference was observed between the obtained results when compared to the reported HPLC method, which proved that the developed methods could be alternative to HPLC techniques in quality control laboratories.
