Acetaminophen is distributed into most body tissues. It crosses placenta and is present in breast milk. Plasma protein binding is negligible at usual therapeutic concentration but increases with increasing concentrations. The elimination half-time varies from about 1 to 3 hours. Acetaminophen is metabolised predominantly in the liver and excreted in the urine mainly as the glucuronide (about 60-80%) and sulfate (about 20-30%) conjugates. Less than 5% is excreted as unchanged acetaminophen. A minor (below 4%) metabolite is usually produced in very small amounts by cytochrom P450.

\n<\/div>\n
\nSymptoms:
\nAcetaminophen toxicity may be due to a single toxic dose, or repeated large doses of acetaminophen (eg 7.5 \u2013 10 g daily, for 1-2 days), or for long-term administration. Dose-related hepatic toxicity is the most severe acute toxicity resulting from overdosage and possibly death.
\nNausea, vomiting and abdominal pain (normally settle within 24 hours of ingestion). After 24 hours symptoms may include right subcostal pain and tenderness, usually indicates development of hepatic necrosis. Liver damage is greatest 3-4 days after ingestion and may lead to encephalopathy, haemorrhage, hypoglycaemia, cerebral oedema and death.
\nTreatment:
\nTreatment is based on plasma concentration. Acetylcysteine protects the liver if administered within 24 hr after ingestion (most effective if given within 8 hours). Dose: 140 mg\/kg orally (loading) followed by 70 mg\/kg every 4 hours for 17 doses. Activated charcoal or gastric lavage may be treated to decrease absorption of acetaminophen.
\nPhenylephrine HCl:<\/strong>
\nSymptoms:
\nPhenylephrine overdosage lead to hypertension, headache, convulsions, cerebral haemorrhage, palpitation, systolic, paresthesia. Bradycardic often occurs soon.
\nTreatment:
\nHypertension can be overcome by taking \u03b1-adrenergic blockers such as phentolamin 5-10 mg, intravenously; if necessary, repeatable. Hemodialysis is often not helpful. Attention to symptomatic treatment and general support, medical care.
\nChlorpheniramine maleate:<\/strong>
\nSymptoms:
\nThe estimated lethal dose of chlorpheniramine is 20 to 50 mg\/kg body weight.
\nThe symptoms and signs of overdosage include sedation, paradoxical stimulation of CNS, toxic psychosis, epilepsy, apnoea, convulsion, muscarinic effects, dystonic reactions, cardiac collapse and arrhythmia.
\nTreatment:
\nSymptomatic treatment and support of living function. Should monitor particularly to cardiac, respiratory, renal and hepatic functions, fluid and electrolyte balance.
\nGastric lavage should be performed or emesis with ipecacuanha syrup. After that, activated charcoal and cathartics may be administered to reduce absorption of chlorpheniramine.
\nIf hypotension and arrhythmia should be treated vigorously. Convulsion may be treated with intravenous diazepam or phenytoin. Haemoperfusion may be used in severe cases.<\/p>\n

\nATC code: R05
\nAcetaminophen is the active metabolite of phenacetin, exhibits analgesic action by peripheral blockage of pain impulse generation. It produces antipyresis by inhibiting the hypothalamic heat-regulating centre. Acetaminophen is used to relieve pain and reduce fever, it may replace aspirin; however, acetaminophen is ineffectively used to treat inflammation. Acetaminophen has effects to relieve pain and fever about as well as aspirin after an equivalent dose. Acetaminophen reduces body temperature in fever patients but it rarely reduces body temperature in normal people. Acetaminophen has rarely effects on cardiovascular and respiratory system after an oral dose. It has no changes of acid-base balance, it does not cause irritation, stomach bleeding or erosion compared to use of aspirin or salicylate. The toxicity in overdosage with acetaminophen is thought to be the production of a metabolite, N-acetyl-p-benzoquinoneimine in the liver.
\nPhenylephrine hydrochloride has similar effect to \u03b11-sympathetic activity which has direct effect on \u03b11-adrenergic receptors causing vasoconstriction and increased blood pressure. Phenylephrine hydrochlorid cause reflex bradycardia, decreasing circulating blood volume and renal blood flow as well as blood flow to many tissues and organs.
\nThe mechanism of action of phenylephrine on \u03b1-adrenergic is by inhibiting cAMP (cAMP: cyclic adenosin -3\u2019, 5\u2019-monophosphate) production via the inhibition of adenyl cyclase enzyme while the \u03b2-adrenergic action is by simulating adenyl cyclase activity.
\nWhen given in nasal mucous membrane, phenylephrine shrinks local blood vessel thus reducing nasal congestion and sinusitis caused by cold.
\nChlorpheniramine maleate is a first-generation antihistamine. It competes with histamine for H1-receptor sites on effector cells in the gastrointestinal tract, blood vessels, and respiratory tract. Its sedative effects are relatively weak compared to other first-generation antihistamines.<\/p>\n
\n<\/div>\n
\nPhenylephrine hydrochloride is irregularly absorbed from the gastrointestinal tract and undergoes first-pass metabolism by monoamine oxidase in the gut and liver. It is almost entirely excreted in the urine.
\nChlorpheniramine maleate is well absorbed after oral doses, and appears in plasma within 30 to 60 minutes. Peak plasma concentration is achieved within 2.5 to 6 hours after oral. Bioavailability is 25-50%. About 70% chlorpheniramine in the circulation is bound to plasma protein. Chlorpheniramine is rapidly and extensively metabolised, metabolites include desmethy-didesmethyl-clorphenamine, and some substances are unknown. Chlorpheniramine is mainly excreted in the urine as unchanged or metabolized form and in the faeces with a small amount. The half-life is 12-15 hours, and may range 280 to 330 hours in chronic renal impairment.<\/p>\n
