Additionally, andrographolide was used in the combination with diclofenac since it has been shown to possess protective effect in the gastrointestinal tract, liver, and kidney and also has analgesic properties.17 (link),18 Doses selected for ED50 determination of both diclofenac and andrographolide were based on notes from previous literature and selected route of administration.17 (link),18 ,29 (link) All drugs were prepared in normal saline with tween-80 added for adequate dispersion of andrographolide (1 drop of tween-80 for every 10 mL of saline). Calculations for preparation of solutions were such that maximum volume of final solution administered to each 150 g rat was not more than 1.5 mL. Normal saline with tween-80 (1 drop of tween-80 per 10 mL of saline) was used as the vehicle and given at a dose not exceeding 10 mL/kg to rats. Purity of diclofenac and andrographolide samples used in this study was confirmed by NMR analysis with the aid of Bruker CMC-assist software (see
Cmc assist software
CMC-assist software is a data processing and analysis tool developed by Bruker. It is designed to assist with the characterization of complex molecular structures, including small molecules, peptides, and proteins. The software provides functionalities for the processing and interpretation of data from various analytical techniques, such as nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, and chromatography.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
