Product Information

Lemsip Max for the temporary relief of pain, including symptoms of cold and flu, body aches and pains, sore throat, and headache. Reduces fever. The systemic availability is subject to first-pass metabolism and varies with dose between 70% and 90%. The drug is rapidly and widely distributed throughout the body and is eliminated from plasma with a T1 /2 of approximately 2 hours. The major metabolites are glucuronide and sulphate conjugates (>80%) which are excreted in urine.

Paracetamol: Paracetamol is absorbed rapidly and completely mainly from the small intestine producing peak plasma levels after 15-20 minutes following oral dosing. Phenylephrine overdose is likely to result in: nervousness, headache, dizziness, insomnia, increased blood pressure, nausea, vomiting, mydriasis, acute angle closure glaucoma (most likely to occur in those with closed angle glaucoma), tachycardia, palpitations, allergic reactions (e.g. rash, urticaria, allergic dermatitis), dysuria, urinary retention (most likely to occur in those with bladder outlet obstruction, such as prostatic hypertrophy). Additional symptoms may include, hypertension, and possibly reflex bradycardia. In severe cases confusion, hallucinations, seizures and arrhythmias may occur. However the amount required to produce serious phenylephrine toxicity would be greater than that required to cause paracetamol-related liver toxicity.relief of aches and pains, sore throat, headache, nasal congestion and lowering of temperature Legal Category: GSL. Paracetamol: Paracetamol is absorbed readily after taking the product and is detected in the plasma within 5 minutes or oral dosing. The pharmacokinetic model shows faster absorption seen over the first 30 minutes for the product compared to a standard does of two paracetamol tablets, however, the overall extent of absorption of both products remains the same. Actual mean plasma levels at each time point show the time to achieve a level of 5 µg/ml is less than 14 minutes, compared to 22 minutes for standard paracetamol tablets; the speed to achieve 10 µg/ml being 19 minutes versus 30 minutes. Tricyclic antidepressants (e.g. amitriptyline): may increase the risk of cardiovascular side effects with phenylephrine (see section 4.3). The anticoagulant effect of warfarin and other coumarins may be enhanced by prolonged regular daily use of paracetamol with increased risk of bleeding; occasional doses have no significant effect. Symptoms of paracetamol overdose in the first 24 hours are pallor, nausea, vomiting, anorexia and abdominal pain. Liver damage may become apparent 12 to 48 hours after ingestion. Abnormalities of glucose metabolism and metabolic acidosis may occur. In severe poisoning, hepatic failure may progress to encephalopathy, haemorrhage, hypoglycaemia, cerebral oedema and death. Acute renal failure with acute tubular necrosis, strongly suggested by loin pain, haematuria and proteinuria, may develop even in the absence of severe liver damage. Cardiac arrhythmias and pancreatitis have been reported.

CYP Inhibitors: Caffeine undergoes extensive metabolism by hepatic microsomal cytochrome P450, factors known to alter the activity of this enzyme system may influence caffeine clearance. Thus, caffeine elimination is enhanced in cigarette smokers and inhibited by cimetidine, disulfiram, and oral contraceptive steroids.Paracetamol: Paracetamol is absorbed rapidly and completely mainly from the small intestine, producing peak plasma levels after 15-20 minutes following oral dosing. The systemic availability is subject to first-pass metabolism and varies with dose between 70% and 90%. The drug is rapidly and widely distributed throughout the body and is eliminated from plasma with a T ½ of approximately 2 hours. The major metabolites are glucuronide and sulphate conjugates (>80%) which are excreted in urine. Information about this product, including adverse reactions, precautions, contra-indications, and method of use can be found at: Sympathomimetic amines: concomitant use of phenylephrine with other sympathomimetic amines can increase the risk of cardiovascular side effects. Indications: For the relief of symptoms associated with the common cold and influenza, including relief of aches and pains, sore throat,
