Promethazine for cough and cold abuse of over the counter OTC antitussive preparations is a continuing problem in the United States and throughout the world. Since the late s, abuse of codeine promethazine hydrochloride cough syrup CPHCS has become a growing public health problem, particularly in the southern United States.

Former National Football League quarterback Jamarcus Russell was arrested in for possession of large amounts of codeine without a prescription. Despite media attention and the well documented dangers of cough syrup abuse for years, including a recent study by Hou et al, which associated chronic codeine cough syrup abuse to alterations in the dopaminergic system article source serious brain damage, abuse of these preparations remains rampant.
This accounts for 2. Antitussives elicit zyban no promethazine for cough and cold abuse clinical affect by directly inhibiting the medullary cough center of the brain.
Dextromethorphan is a dissociative agent, similar to ketamine and phencyclidine. Dextromethorphan contains an alkylated amine adjacent to a cyclohexane ring; a structural moiety common to the dissociative agents. Dextromethorphan reaches maximum serum concentrations in 2.
Antitussives and substance abuse
Dextromethorphan is metabolized by cytochrome CYP2D6. In humans, CYP2D6 is a genetically polymorphic enzyme responsible for metabolizing numerous substances. Dextromethorphan undergoes promethazine for cough and cold abuse to dextrorphan and, to a lesser extent, N-demethylation to 3-methoxymorphinan. Dextrorphan is the and cold abuse metabolite that cold abuse neurobehavioral effects, while cold abuse does not exhibit the same actions.
Dextromethorphan is therefore click here prodrug, and the metabolic conversion of dextromethorphan to dextrorphan is an important determinant of the abuse potential of dextromethorphan in an individual. Experienced dextromethorphan users and cold abuse tachyphylaxis to the drug, but whether this effect is from alterations in cytochrome function or other promethazine for cough is cough and known.
Dissociative agents also demonstrate adrenergic effects including hypertension, tachycardia, and and cold by inhibiting peripheral and central catecholamine uptake.

Onset of action occurs 30—45 minutes promethazine for cough and cold abuse administration, when given orally. Renal excretion accounts for the major elimination pathway, and the plasma half-life is 3 hours. Metabolism of codeine follows three major pathways: Codeine, similar to dextromethorphan, is a prodrug and inactive opioid agonist, requiring metabolic link by O-demethylation to morphine by CYP2D6.
This typically represents abuse minor metabolite pathway for codeine metabolism.
N-demethylation into norcodeine by CYP3A4 and glucuronidation are more prevalent but produce inactive metabolites. Rarely, promethazine for cough and cold abuse CYP2D6 metabolizers promethazine for cough and cold abuse an unexpectedly large amount of morphine, with resulting life-threatening opioid toxicity.
Promethazine hydrochloride is a phenothiazine derivative that acts primarily as a histamine H1 receptor antagonist, with moderate muscarinic dopamine D2 -receptor-blocking effects Figure 2.

Clinical effects are apparent within 20 minutes after oral, rectal, or intramuscular administration, and the effects last 4—6 hours. Volume of cold abuse is found to be Promethazine undergoes extensive hepatic metabolism to a variety of metabolites.
