Pharmacodynamics
The action of Pharmacitron is determined by the pharmacological properties of its components.
Paracetamol has a central effect, inhibiting the enzymatic activity of cyclooxygenase, thereby contributing to a reduction in pain and a decrease in body temperature. Minor effects on the synthesis of proinflammatory mediators (prostaglandins) in peripheral tissues, which explains the safety of the drug with respect to water-electrolyte equilibrium in the body and the absence of damaging effect on the mucosa of the gastrointestinal tract.
Pheniramine maleate - a blocker of H1-histamine and M-cholinergic receptors, has a speed that consists in suppressing the allergic reaction, removing spasms, reducing nasal phenomena - a runny nose, nasal congestion.
Phenylephrine hydrochloride - adrenostimulator, causes narrowing of arterioles, which helps to remove the edema of the mucous membrane of the pharynx and nose, reduces the secretion of tear fluid.
Ascorbic acid is a necessary component of metabolic processes and oxidation-reduction reactions, cell renewal and synthesis of steroids. Strengthens blood vessels, the immune system, activates and normalizes the processes of hematopoiesis, circulation, oxygenation.
Pharmacokinetics
Paracetamol has a good absorption rate in the upper intestine and distribution in organs and tissues. Decrease in body temperature occurs 1.5-2 hours after oral administration. The presence in the preparation of vitamin C increases the effectiveness of paracetamol and its tolerability. In the liver it is split into glucorangide and paracetamol sulfate, which are eliminated mainly in urine, like phenyramine maleate and its metabolites. Accepted orally phenylephrine hydrochloride is practically not absorbed from the digestive tract, its cleavage occurs in the intestinal wall with the participation of monoamine oxidase, and also in the liver.

In case of dysregulation (exceeding dose) and duration of administration, there is a high probability of hepatotoxicity - in the form of anemia (hemolytic or aplastic), methemoglobinemia, violations of the blood formula in the form of a decrease in its basic parameters, or nephrotoxicity of paracetamol - renal colic, the presence of glucose in urine, necrotic papillitis , inflammation of the interstitial tissue of the kidneys.
Dosing and administration
The contents of the sachet should be poured into a glass (200ml) with hot water, but not with boiling water. When will dissolve, drink. Take no more than four times during the day. After five days, stop Pharmacitron and, if necessary, switch to another antipyretic (analgesic) drug that does not contain paracetamol.
Overdose
Symptoms of exceeding the admissible dose of Pharmacitron are manifested as signs of a paracetamol overdose: the patient is pale, he does not feel hungry, he is sick, there may be vomiting, diarrhea, jaundice and other signs of necrotic changes in the liver. The severity of signs of intoxication depends on the dose taken and may appear after the use of a dose of 10 or 15 g of paracetamol (meaning adult patients). There is a jump in the enzymatic activity of hepatic transaminases, blood coagulability worsens. Such deviations in the blood can already be detected after 12 hours after taking an increased dose of the drug. The unfavorable symptoms of toxic hepatosis may appear after 24 hours, sometimes up to five days. Occasionally there is an instant development of hepatic insufficiency, complicated by necrosis of the kidney tissue.
First aid to a patient taking an increased dose of paracetamol to prevent a hepatotoxic effect consists in washing the stomach and taking enterosorbents. Eight hours after taking an increased dose of detoxification products, Unithiol or Dimaval (SH-grupp donors) and the precursors of glutathione-methionine synthesis are administered. If from the moment of taking an increased dose 12 hours pass it is recommended to introduce N-acetylcysteine. Further treatment is carried out depending on the dose taken, the time interval elapsed from its adoption, and the severity of the consequences of an overdose.
Interactions with other drugs
