Problems solved by technology

The reproducibility and stability of the determination conditions formulated by the above studies are not very ideal in actual use, especially the sensitivity and accuracy of using a thin-layer scanner to measure the content of chlorpheniramine maleate in mango cough tablets are not good. Very good, so these methods have not been included in the specifications for this formulation
