This occurs because atropine is a competitive antagonist of the muscarinic acetylcholine receptors (acetylcholine being the main neurotransmitter used by the parasympathetic nervous system). Therefore, it may cause swallowing difficulties and reduced secretions.   Analyse  Test ItemsStandardCharacterA white or almost white amorphous powderSpecific Optical Rotation-7.0°~9.0°Water≤3.5%SOLUBILITY 40 °C Soluble in tetrahydrofuran, 20 °Cslightly soluble in water, Insoluble inether.PARTICLE SIZE180-150μmCa %3.0~3.6Heavy Metals(ppm)≤10X-RAY Diffractionamorphous Impurity(HPLC) Atorvastatin Lactone ≤0.1%Desfluoro-atorvastatin calcium ≤0.2%Diamine –atorvastatin calcium ≤0.3%Isomer-atorvastatin calcium ≤0.2%Other individual unknown Impurity %≤0.2%Total impurities≤1.0%Assay98.0-102.0%
