As for the case of intravenous injection, it only takes about 3 to 5 minutes.
When the compound Promethazine enters the body, the rate of binding to plasma proteins will be about 76 to 93%. At the same time, the drug will be widely distributed to tissues in the body. Although concentrations of the drug are lower in the brain than in other organs of the body, these concentrations are still higher than those in plasma. For pregnant women, when the drug enters the body, it will easily cross the placenta. However, there is no evidence of the distribution of the drug in breast milk.
When Promethazine compounds enter the body, they will be strongly metabolized in the liver and produce mainly promethazine sulphoxide and N-dimethyl promethazine. After entering the body, the drug is eliminated via urine, feces, and compounds are excreted mainly in the form of promethazine sulphoxide and glucuronide form.
Promethazine when entering the body has antiemetic, or anticholinergic effects, or against motion sickness or local numbness. Furthermore, the drug has a mild antitussive effect or may reflect a potential for respiratory depression. In addition, Promethazine also acts as an H1-receptor blocker by competing with histamine for H1-receptor sites on effector cells. However, it is unlikely to block histamine release. Therefore, the drug Pipolphen is only able to block the reaction caused by histamine.
