The Introductction of Promethazine Hydrochloride :
Promethazine hydrochloride (English: Promethazine, also known as Promethazine Hydrochloride or Chemalbook Phenergan) is a common cough medicine. It is the first generation antihistamine, which can competitively block histamine H1 receptor, resist histamine induced telangiectasia, and reduce its.
Promethazine is a phenothiazine derivative which differs structurally from the antipsychotic phenothiazines by the presence of a branched side chain and no ring substitution. It is thought that this configuration is responsible for its relative lack (1/10 that of chlorpromazine) of dopamine antagonist properties.
Promethazine is an H1 receptor blocking agent. In addition to its antihistaminic action, it provides clinically useful sedative and antiemetic effects.
