MSDS Information

Promethazine hydrochloride Usage And Synthesis

Overview

Promethazine (PM) ((RS)-N, N-dimethyl-1-(10H-phenothiazine-10-yl)propan-2-amine hydrochloride) is a phenothiazine derivative. It is a first-generation H1 receptor antagonist, antihistamine, and antiemetic medication and can also have strong sedative effects^[1]. Promethazine affects ligand gated ion channels such as purinergic P2 or cholinergic ACh receptors and voltage dependent ion channels such as sodium, calcium, or potassium channels.
Beside, these effects, promethazine also inhibit the brain NaþKþ-ATPase and the mitochondrial permeability transition pore. Since its first introduction in 1946, it has been used for prevention and treatment of nausea and vomiting caused by narcotic therapy, migraine episodes, cancer chemotherapy, and so forth.^[2] Meanwhile, it has become apparent that this drug interacts with many different receptors. It works by changing the actions of chemicals in brain and as an antihistamine^[2]. It is used to treat allergic symptoms such as itching, runny nose, sneezing, itchy or watery eyes, hives, and itchy skin rashes, also to prevent motion sickness, and treat to nausea and vomiting pain after surgery and as a sedative or sleep aid, especially for oncologic patients. However, second-generation oral antihistamines are the preferred first-line treatment option for allergic rhinitis and urticarial, although topical first-generation antihistamines are still prescribed by general healthcare practitioner and pharmacists too easily, without taking into account possible side effects as a first line treatment for several dermatological problems^[3–8].

Figure 1. The chemical structure of promethazine

Pharmacodynamics

PM is well absorbed from the gastrointestinal tract. Peak plasma concentrations occur after 2 to 3 hours when promethazine is administered orally (25 to 50mg) or intramuscularly (25mg). Following rectal administration of promethazine in a suppository formulation, peak plasma concentrations were observed after about 8 hours. Oral bioavailability is approximately 25%. Rectal bioavailability has been reported at 23%. Promethazine is widely distributed in body tissues and has a large apparent volume of distribution following oral and intramuscular administration. Promethazine has been reported to be 93% protein-bound when determined by gas chromatography and as 76 to 80% protein-bound when determined by HPLC. Promethazine rapidly crosses the placenta, appearing in the cord blood within 1.5 minutes when given intravenously at term. Promethazine crosses the blood brain barrier. The elimination half-life of promethazine following oral administration has been estimated to be within the range of 12 to 15 hours. After intravenous administration of 12.5mg, blood concentrations of promethazine declined bio-exponentially with a terminal elimination half-life of 12 hours^[5]. PM is metabolized principally to promethazine sulphoxide and to a lesser degree desmethylpromethazine. The major site of metabolism is the liver and that the drug is subjected to extensive first-pass hepatic biotransformation, explaining the oral bioavailability of 25%. Metabolism also occurs in the gut wall but to a lesser degree than earlier postulated. The sulphoxide metabolite has not been detected after intramuscular dosing as circulating levels are probably below analytical detection limits due to a combination of slow absorption, lower dose (50% of oral), and bypass of first-pass metabolism in the liver^[3]. Its elimination is primarily due to hepatic metabolism. No evidence was found to suggest that metabolites of promethazine are pharmacologically or toxicologically active. Promethazine has not been reliably detected in breast milk^[4].
