Paracetamol is considered the main active metabolite of phenacetin and acetanidile with analgesic and antipyretic properties. Paracetamol has equivalent analgesic and the antipyretic aspirin whilst it expresses weak anti-inflammatory action therefore its use in inflammatory rheumatic diseases is limited.
The mechanism of its analgesic action is still unclear. It is believed that mainly acts by inhibiting prostaglandins biosynthesis and to a lesser extent by peripherically inhibiting algogenic stimulus origin of.
The peripheral action is due also to inhibition of prostaglandin biosynthesis or inhibition or other endogenous substances action that sensitize pain’s receptors after mechanic or chemical stimulation. As far as its antipyretic action, Paracetamol induces temperature fall in subjects with fever but not in normal subjects. It is believed that the antipyretic effect of Paracetamol is due to central action on the control center temperature hypothalamus resulting in peripheral vasodilation results in an increase in peripheral blood flow, sweating and temperature loss.
This peripheral action of Paracetamol is due also to inhibition of prostaglandin biosynthesis in the hypothalamus. Paracetamol administered in recommended doses has no effect on the cardiovascular and respiratory system nor provokes disorders acid-base balance. Several studies have confirmed the effectiveness and safety of Paracetamol for parenteral administration. Paracetamol is well absorbed when intramuscularly administered and its blood level is similar to that obtained after oral administration.
The absorption rate is slower of that obtained when Paracetamol hiosdina orally administered, resulting in desirable blood levels for a longer time. Fifteen years ago, combinations of Paracetamol with other substances such butjlbromuro analgesics aspirin, codeinespasmolytics N-hyoscine butylbromide, mebeverine etcor antidotes for acetaminophen toxicity were administered orally or rectally but not parenterally intramuscularly or intravenously.
Therefore, preparation of parenteral solutions of Paracetamol and combinations of mecanisjo with other substances as above mentioned, are considered indispensable for use in modern therapeutics in order to achieve faster and greater therapeutic effect. While Paracetamol is soluble in many organic solvents, solutions of Paracetamol in such solvents are unfit for therapeutical use, because of the toxicity that occur when administered parenterally intramuscularly or intravenously and because of the presence of problems technical such as chemical instability leading to the formation of precipitates, low fluidity etc.
As explained above, the preparations of injectable solutions of Paracetamol and combinations of Paracetamol with other active substances require the choice of solvent nutilbromuro mixture of solvents, comprising also water, reciprocating to certain requirements of suitability as: But it is important that the solvents selected do not interfere with the therapeutic properties of Paracetamol or other substances.
From the pharmacotechnical point of view, the solvent or solvent system chosen must have the full ability of mixing with water not only because this way the manufacturing process will be provided but the manufacturing costs will also be reduced.
Furthermore, this property of fully mixing with water makes depended largely pharmacokinetics butilbrokuro bioavailability of the preparation and the local tolerance at the injection site.

GR and disclose GR injectable hisocina of Paracetamol comprising a solvent system of glycerol formal, ethanol and water. According to the present invention chemically stable solutions of Paracetamol, useful for parenteral administration as well as solutions of Paracetamol with other active substances such as with Codeine for a preparation with increased analgesic or with N-Butylbromide effect for a preparation obtained spasm-analgesic effect.
Since Paracetamol is not soluble in water, efforts made for its dissolution into organic solvents or mixtures of them, suitable for butilbrmouro use. Our experiments for the discovery of proper solvents for Paracetamol’s hioscinz, have shown that there are at least two 2 systems in which other are also soluble active substances that may be combined with Paracetamol for therapeutical uses.
To this solvent mixture, add the following organic materials: Lidocaine hydrochloride local anestheticDisodium Edetate, Sodium Metabisulfite antioxidant agent and Disodium Phosphate buffer pH 5. The resulting solution of the mixture of these materials with the mixture of solvents, is a clear and stable solution and constitutes the “basic” solution of Paracetamol for parenteral administration, which will be subsequently used as is for the preparation of parenteral solution combinations of Paracetamol with other active substances such as N-Butylbromide, Codeine phosphate etc.
