What is Promethazine?
Active Ingredients: Promethazine HCl
Promethazine HCl Tablets are a drug used to treat symptoms caused by allergic rhinitis and allergic conjunctivitis. This medication is also indicated for use as an antiemetic agent in the active and prophylactic treatment of motion sickness. When combined with other medications, promethazine may be used to treat anaphylaxis.
Promethazine HCl is also used for sedation or the control of nausea or vomiting associated with certain types of anesthesia or surgery.
Promethazine HCl is classified in the family of medicines known as phenothiazines. It is an H1-antagonist with anticholinergic, sedative, and antiemetic effects and some local anesthetic properties.
This drug is well absorbed after oral administration and clinical effects are apparent within 20 minutes after administration. The effect generally lasts 4 to 6 hours. This effect may also last for up to 12 hours. Promethazine is metabolized by the liver to various compounds, including promethazine sulfoxide, and minorly to desmethyl promethazine and a hydroxy metabolite. This medication is excreted through the urine.
This product is also available in the form of syrup.

Oral premedication for the prevention of hypersensitivity reactions to paclitaxel
This is a prospective study that evaluates the availability and safety of the administration of promethazine and dexamethasone per os in the premedication of paclitaxel hypersensitivity reactions.
It includes 180 eligible cancer patients: 100 patients received paclitaxel weekly while 80 patients received paclitaxel every 3 weeks. All these patients received premedication with promethazine 25mg per os, dexamethasone 2-20mg per os, and cimetidine 300mg intravenously. Out of the 100 patients, hypersensitivity reactions occurred only in one patient (1%). Out of the 80 patients hypersensitivity reactions occurred in 3 patients (4%), while there were no adverse hypersensitivity reactions in 96% of patients.
The conclusion of this study is that premedication with promethazine and dexamethasone reduces hypersensitivity reactions in patients and shortens the time of treatment for patients and treating staff.
