: Inductively coupled plasma is a new technique employed for the determination of elemental impurities in pharmaceutical ingredients viz. raw materials, drug substance, and drug product dosage forms. New US FDA and EMA regulations came into effect from Jan 2018 as industry standard requirements for the determination of inorganic elemental impurities using ICP-OES/AES or ICP-MS analytical techniques. The method development was optimized for the determination of the listed elements as per USP <232> <233> elemental impurities-limits and procedures. It also demonstrates the validation of the method and verification/transfer of the method which also provides an insight into the presence of free elemental atomics of the gaseous form of the sample (drug substance, drug product or excipients), thus helping in determining the concentration of the element of interest. Also, the regulatory guidance is very general and does not explain the sample specifications for the individual element concentrations. Thus, this review emphasizes the routine instrumental maintenance, analytical method development challenges, trends in the performance of analytical method validation and verification/ transfer activities of the various pharmaceutical dosage forms outlined with acceptance criterion.

A highly selective, specific, precise sensitive and reliable ICPMS method has been developed and validated by using ICP-MS for the determination of multielement in Sucroferric oxyhydroxide. The described ICP-MS method provides specific detection and quantification of minor and trace elements from 0.3J(30%) to 2J(200%) of its individual specification of each element i.e Ag, As, Au, Ba, Cd, Co, Cr, Cu, Hg, Ir, Li, Mo, Ni, Os, Pb, Pd, Pt, Rh, Ru, Sb, Se, Sn, Tl,  and V.The analytical method found to be Linear for each individual element with working concentration range from 30%, 50%, 100%, 150% and 200% i.e 0.3J, 0.5J, 1J, 1.5J and 2J with correlation coefficient not less than 0.990.The % recoveries of elemental impurities of each individual elements at three different concentrations with spiking in samples were found to be an acceptable range as 70% to 150%.The method was found to be precise and robust and its relative standard deviation was below 20%.The actual observed relative standard deviation in Precision was found to be in an acceptable range. Therefore developed method can be use for routine quantitative analysis of elemental impurities like Ag, As, Au, Ba, Cd, Co, Cr, Cu, Hg, Ir, Li, Mo, Ni, Os, Pb, Pd, Pt, Rh, Ru, Sb, Se, Sn, Tl, and V to ensure the quality of drug product.

Microwave Assisted Digestion

Fast and simple closed-vessel microwave-assisted digestion procedure was developed for decomposition of three pharmaceutical dosage forms of ibuprofen such as tablets, suspension and gel, prior to elemental impurity analysis by one robust and precise ICP-OES method. Samples were digested by four-step microwave program consisting of a 10 min temperature gradient to 180°C, maintained at 180°C for 10 min, followed by 5 min ramping time to 210°C with holding time of 10 min on 210°C. Subsequently, ICP-OES method was developed and validated for simultaneous determination of selected elemental impurities. Results of recovery studies range between 77% and 105% for each element in all analyzed formulations. Correlation coefficients of the regression equations were higher than 0.999 for all analyzed elements. Validation results reveal that the proposed method is specific, accurate, and precise and could be applied for simultaneous quantitative analysis of multi element solutions in different pharmaceutical dosage forms of ibuprofen.

A simple and precise RP‐HPLC method was developed and validated for the determination of pioglitazone hydrochloride in pharmaceutical dosage forms. Chromatography was carried out using Kromosil- C18 ODS column (250 x 4.6 mm; 5 μm), mixture of acetate buffer: methanol (40:60 v/v) as the mobile phase at a flow rate 1.0 mL/min. The analyte was monitored using UV detector at 254 nm. The retention time for pioglitazone HCl was 3.063 min. The proposed method was found linear in the concentration range of 20.0‐70.0 μg/ml with correlation coefficient of r2=0.9999. The developed method has been statistically validated and found simple and accurate. The mean recoveries obtained for pioglitazone HCl were in the range 99.20-101.59%. Due to its simplicity, rapidness, high precision and accuracy of the proposed method it may be used for determining pioglitazone HCl in bulk and dosage forms.
