Acetphenetidin U.S.P.

Source URL:
First marketed in 1887
Class (Stereo):
CHEMICAL (ACHIRAL)
Conditions:
Phenacetin was used as an analgesic and fever-reducing drug in both human and veterinary medicine for many years. Since a major portion of a dose of phenacetin is rapidly metabolised to paracetamol, it seems possible that phenacetin owes some of its therapeutic activity to its main metabolite, paracetamol, whereas its most troublesome side effect (methaemoglobinaemia) is due to another metabolite, p-phenetidine.
Phenacetin was shown to inhibit cyclooxygenase (COX)-3, a cyclooxygenase-1 variant while p-phenetidine potently inhibits both COX-1 and COX-2. There is sufficient evidence in humans for the carcinogenicity of analgesic mixtures containing phenacetin. Analgesic mixtures containing phenacetin cause cancer of the renal pelvis, and of the ureter. Phenacetin was withdrawn from many analgesic mixtures long before the legal ban in several countries.

First marketed in 1886
Class (Stereo):
CHEMICAL (ACHIRAL)
Conditions:
Acetanilide is a synthetic organic compound introduced clinically in 1886 as a fever-reducing drug. Its effectiveness in relieving pain was discovered soon thereafter and it was used as an alternative to aspirin for many years in treating such common complaints as headaches, menstrual cramps, and rheumatism. Unfortunately, Acetanilide exhibited an unacceptable profile of toxic effects, the most alarming being cyanosis due to methemoglobinemia. The toxic profile prompted the search for supposedly less toxic aniline derivatives such as phenacetin. After several conflicting results over the ensuing fifty years, it was established in 1948 that acetanilide was mostly metabolized to paracetamol (USAN: acetaminophen) in the human body and that it was the paracetamol that was responsible for the analgesic and antipyretic properties. Paracetamol has since replaced acetanilide usage because it is less likely to induce blood disorders. The observed methemoglobinemia after acetanilide administration was ascribed to the small proportion of acetanilide that is hydrolyzed to aniline in the body. Acetanilide is no longer used as a drug in its own right, although its primary metabolite, paracetamol, has been widely succesful.

Class (Stereo):
CHEMICAL (ACHIRAL)
Conditions:
p-Aminophenol is an active metabolite of paracetamol. p-Aminophenol is conjugated with arachidonic acid by fatty acid amide hydrolase to form AM404. AM404 exerts effect through cannabinoid receptors. p- Aminophenol is a nephrotoxic metabolite of paracetamol and phenacetin. It causes acute renal proximal tubular necrosis after administration to rats. p-Aminophenol may cause skin sensitization, dermatitis. p-Aminophenol is a synthetic dye used in hair coloring.
