Doliprane 1000mg sachet 8: Dosage and administration
Method of administration
Orally.
Pour the contents of the sachet into a glass and add a small amount of drink (eg water, milk, fruit juice). Stir and drink immediately.
Dosage
Attention: This presentation contains 1000 mg of paracetamol per unit: 2 units do not take the time .
This presentation is reserved for adults and children over 50 kg (about 15 years).
The usual dosage unit is a bag of 1000 mg per dose, to be repeated if necessary after 4 hours minimum.
It is usually not necessary to exceed 3 g of acetaminophen per day, or 3 sachets per day.
However, in case of more severe pain, the maximum dose may be increased up to 4 g per day, 4 sachets per day. Always observe an interval of 4 hours between doses.
Maximum recommended doses: see section Special warnings and precautions for use Special warnings .
Frequency of administration
Systematic decision can avoid oscillations of pain or fever:
- adults, they should be spaced at least 4 hours.
Renal
In case of severe renal impairment (creatinine clearance less than 10 ml / min), the interval between shots will be at least 8 hours.
Do not exceed 3 g paracetamol per day, or 3 sachets.

Doliprane 1 000mg bag 8: Pharmacokinetic Properties
Absorption
The absorption of oral paracetamol is complete and fast. Maximum plasma concentrations are reached on average 30 to 60 minutes after ingestion.
Distribution
Paracetamol is rapidly distributed to all tissues. Concentrations are comparable in the blood, saliva and plasma. The plasma protein binding is low.
Metabolism
Paracetamol is metabolized primarily in the liver.
The two major metabolic pathways are glucuronidation and sulfation.
The latter route is rapidly saturable at doses higher than therapeutic doses. A minor pathway catalyzed by cytochrome P 450, is the formation of a reactive intermediate (N-acetyl benzoquinone imine), which under normal conditions of use, is rapidly detoxified by reduced glutathione and excreted in urine after conjugation with cysteine and mercapturic acid.
However, when mass poisoning, the amount of this toxic metabolite is increased.
Elimination
Elimination is essentially urinary.
90% of the ingested dose is excreted by the kidneys within 24 hours, mainly as glucuronide (60-80%) and sulphate (20-30%). Less than 5% is excreted unchanged.
The elimination half-life is approximately 2 hours.
Pathophysiological changes
· Renal impairment :
in patients with renal impairment (creatinine clearance less than 10 ml / min), the elimination of paracetamol and its metabolites is delayed.
· Elderly :
the ability of conjugation is not changed.
