Pharmacodynamics and pharmacokinetics

Pharmacodynamics

Rhinza is a combination medicine, its list of effects is the sum of the effects of the components of the drug.

Paracetamol possesses analgesicandantipyretic effect. Relieves pain in the head, back, joints, throat, pain arising from colds, and also reduces fever.

Paracetamol inhibits enzymes cyclooxygenase-1 and cyclooxygenase-2reduces synthesis prostaglandinsand affects the center of thermoregulation of the nervous system. In the inflamed tissues is blocked by special enzymes, therefore inactivation cyclooxygenase-1 and -2 they are insignificant, this explains the unimportant anti-inflammatory effect. However, paracetamol effectively stops the production of prostaglandins in the cells of the nervous system, as a result it only reduces the elevated temperature and does not affect the normal body temperature. Paracetamol does not affect the gastric mucosa unlike other nonsteroidal anti-inflammatory drugs. Receiving paracetamol in therapeutic doses does not affect the water-mineral metabolism and other types of metabolism.

Phenylephrine refers to alpha-adrenomimetikam. Reduces the lumen of blood vessels, resulting in swelling and hyperemia of the mucous membranes of the nasopharynx, nose and sinuses.

Chlorphenamine is a histamine receptor blocker and has antiallergic action, and also reduces swelling and hyperemia of the mucous membranes of the nasopharynx, nose and sinuses, helps to weaken exudative manifestations.

Caffeine has a stimulating effect on the nervous system, which reduces fatigue and drowsiness, leads to an increase in mental and physical performance. Strengthens and accelerates the anesthetic effect of paracetamol.

Pharmacokinetics

Paracetamol is rapidly absorbed from the middle parts of the digestive system, it is actively associated with plasma proteins. The highest concentration in the blood - 1 hour after consumption. Paracetamol can penetrate blood-brain barrierand placenta.

Instructions for use Rinza

The instructions for Rinza clearly indicate how to take the pills, and it does not differ in the multiplicity and mode of administration from the instructions for Rinza vulture powder.

  • pallor of the skin, lack of appetite, nausea, diarrhea, discomfort in the stomach,
  • level up bilirubindecreasing value prothrombin,
  • hepatotoxic effect - pain in hypochondrium on the right, weakness, sweating, jaundice, hepatomegaly, increased liver enzymes,
  • in rare cases may develop hepatonecrosis with the addition of hepatic encephalopathy (deterioration of cognitive functions and indicators of higher nervous activity), disseminated intravascular coagulability syndromemetabolic acidosis hypoglycemia, rhythm disturbances, convulsive state, comaswelling of the brain collapse.

More rarely, liver dysfunction can develop with lightning speed while simultaneously adding renal failure. When taking very large doses are possible: disorientation, agitation, sleep disturbance, dizziness, heart rhythm disturbances, development of pancreatitis. With long-term intake of large doses of the drug may develop aplasticanemia, neutropenia, agranulocytosis, pancytopenia, leukopenia, thrombocytopenia.

Symptoms of an overdose of phenylephrine hydrochloride: dizziness, confusion, arrhythmia, tremor of the limbs, nervousness, anxiety.

Symptoms of an overdose of chlorfenmine maleate: dilated pupils, photophobia, dry mouth, hyperthermiaintestinal atony, bradycardia, arterial hypotension.

Symptoms of overdose caffeine: headache, tremor, excitability, the appearance of extrasystoles.

Overdose treatment: gastric lavage, taking activated carbonsymptomatic therapy (methionineafter 8 hours and N-acetylcysteine after 12 hours of overdose), monitoring of external respiration and cardiac activity. If seizures occur, they recommend taking it. diazepam.

Interaction

It is necessary to avoid combination of taking Rinza with other drugs containing phenylephrine, paracetamol, chlorphenamineor caffeine.

Rinza enhances the effect beta blockers, MAO inhibitors andsedatives drugs. When taking Rinza with antidepressants, antipsychotics and anti-parkinsonian drugs, urinary retention, dry mouth, and constipation may appear.

Paracetamol reduces the effectiveness of diuretic drugs and increases the possibility of toxic effects on the liver while taking it with barbiturates, carbamazepine, difenin, rifampicin.

Barbiturates reduce the antipyretic effect of paracetamol. The speed of absorption in the digestive tract of paracetamol may increase when combined with metoclopramide and domperidone. The effects of paracetamol are enhanced by its combination with ascorbic acid, codeine, chlorphenamine, scopolamine, propiphenazone and caffeine. Taking paracetamol with nonsteroidal anti-inflammatory drugsincreases the risk of renal complications. One of the main components of the drug phenylephrine hydrochloride exhibits adrenomimetic properties when combined with tricyclic antidepressants.

The use of Rinza tablets reduces the ability guanethidine reduce the pressure. Sharing phenylephrine hydrochloride with digoxin in pills and other cardiac glycosides can lead to development arrhythmias and even heart attack. Phenylephrine reduce efficacy beta blockers and other antihypertensive drugs (for example, reserpine and methyldopes).

Chlorphenamine Maleate enhances the sleeping pill barbiturates, neuroleptics, tranquilizers, anesthetics, narcotic analgesics.

Caffeine as part of Rinza improves bioavailability other analgesic antipyreticenhances the effects of some derivatives xanthine,alpha- andbeta adrenomimetics, psychoactive drugs. Cimetidine, isoniazid, hormonalcontraceptives potentiate the effect of caffeine. Caffeine reduces the effect of taking opioid analgesics, sedativesfunds for anesthesia and drugs that depress the central nervous system. Caffeine reduces the concentration of lithium in the blood.

Special instructions

Do not exceed the dose specified in the instructions. Do not use with sedatives, sleeping pills and other drugs containing paracetamol or other substances present in the composition of Rinza.

The drug is prescribed exclusively by a doctor if the patient has: hypertension, prostate adenoma, rhythm disorders, pheochromocytoma, urinary delay.

If the drug must be used for a long time, monitoring of the functional state of the liver and the blood condition is obligatory.

During the period of use of the drug should not abuse coffee, strong tea, other tonic drinks, as there may be problems with sleep, as well as the appearance of irritability, heart palpitationsdizziness arrhythmias.

The use of Rinza may affect the result.doping control.

If the temperature rise persists for more than three days, you should contact your doctor.
