There may be some side effects such as burning of the skin, redness, itching, or peeling. Hence, it needs to be administered very carefully.  (13)

Mechanism of action of Erythromycin Thiocyanate

Erythromycin, when administered, combines with the 50s subunit of the r RNA bacteria. This attachment impairs the protein synthesis and functioning of the bacteria. It interferes with aminoacyl translocation. Hence the rRNA fails to go from the A site to the P site of the complex. This breaks the chain of nascent polypeptide attachment to the amino acid. This inhibits the further growth of bacteria and brings an end to the spread of infection.

Erythromycin also acts as a Motilin receptor agonist, in the gut. It binds with the Motilin receptor to increase gut mobility. (1)

Erythromycin Thiocyanate manufacturing process

Erythromycin Thiocyanate is extracted using a counter current extractor from the fermented broth of Saccharopolyspora erythraea. It is dissolved in solvents containing amyl acetate and ethylene dichloride. The resin column extraction is then done using column chromatography at the pilot scale. The microfiltration downstream process of Erythromycin Thiocyanate is done from the broth. It is then extracted in a resin column using butyl acetate as a solvent. This finally results in the finished product Erythromycin Thiocyanate in the powder form with an overall 90% yield. (14)
