An important condition for obtaining a high-quality drug is the determination of critical points and parameters of the production process, which is divided into several successive stages. The aim study of the critical parameters of the production of tablets and capsules with vegetable raw materials. For this purpose, validation studies of technological processes were carried out for tablets with dry extract of Scutellaria baicalensis and hard gelatin capsules with vegetable raw materials. The subject of our research was the technological process of obtaining tablets based on dry extract of the roots and rhizomes of Baikal skullcap and hard gelatin capsules based on crushed raw materials. We have identified critical process parameters for each stage. Validation tests were carried out for certain critical process parameters and acceptance criteria were calculated. Quality control of finished tablets based on dry extract of Baikal skullcap and finished hard gelatin capsules based on crushed roots and rhizomes of Baikal skullcap was performed according to the following indicators: appearance, identification, average weight, mass uniformity, disintegration, dissolution, abrasion, microbiological purity, quantitative determination . The obtained validation data of experimental-industrial series meet the acceptance criteria, and the developed technology is reproducible and promising for further validation. On the basis of the obtained results, it can be concluded that the established critical values of the parameters of the production processes and their conditions of carrying out allow for stable and reliable production of semi-finished and finished products that meet the quality standards in accordance with regulatory documents.

: In the current virus infection and pandemic situation, the extremely convenient gold nanoparticles sensor (AuNPs) dependent antibody & antigen detection kits are very important assays for infection detection. Various laboratories & manufactures across the globe are utilizing different kits development & manufacturing process but development of kits and large scale manufacturing are two different things. A manufacturing process needs to be controlled for financial, quality and regulatory compliance. The best way to control the process is by statistical method. The process produces products that contain variables as critical quality attributes (dependent variables) are predicted over the processing time. There are distinct immune –chromatographic point to care diagnosis devices and kits available with different quality attributes like antigenantibody proteins, aptamers, markers (nanoparticles, latex beads, and fluorescence) and devices performance attributes etc. Such attributes add uncertainty to the durability of such instruments. The gold nanoparticles are one of key attribute, which certainly defines the performance of kits (sensitivity, specificity and uniformity). To establishing the manufacturing process capability, the static tolerance intervals are critical for the synthesis of gold nanoparticles, protein conjugation and nitrocellulose membrane coating. . In the immune test kits, critical process parameters (independent variable) that affect dependent responses can be controlled statistically by fitting purpose methodology. The manufacturing process is to be established in the state on engineering control by setting up the critical process parameters. Statistically, the manufacturers can predict and handle out-of-specification (OOS) results even if the process is inconsistent and unstable. This article provides scientific tools to the reader to determine whether or not a gold nanoparticles based immune-chromatographic development process is statically capable for scale-up.

In the present study custom screening design was employed to observe the effect of four critical process parameters on particle size and polydispersity index of the liposomal formulation made by ethanol injection method. The four process parameters selected were lipid ratio, rate of injection, phase volume ratio and rotational speed of magnetic stirring. Eight different liposomal formulations were prepared using the design. The formulations were subjected to particle size analysis. The analysis was done at a significance level p<0.05 and found that the process parameters had significant effect on the particle size and polydispersity index of the formulations. The design was optimized for the individual responses with an overall desirability of more than 50%. Three batches of liposomes were formulated at optimized process parameters which matched the target as predicted by the design. Therefore, it can be concluded that the design was effective in production of nano sized stable monodisperse liposomes by ethanol injection method. Dhaka Univ. J. Pharm.
