The tablets also contain auxiliary ingredients:

• Lactose.
• Talc.
• Starch.
• Magnesium stearate.
• Calcium stearate.
• Povidone.

Auxiliary ingredients have no therapeutic effect. They are necessary to preserve the chemical formula.

Mechanism of action

The principle of action of the drug lies in its ability to destroy viruses that provoke various acute diseases. Rimantadine hydrochloride is effective against various strains of the type A virus, which makes it possible to use a medication for the treatment of influenza provoked by this pathogen.

As a result, the symptoms are quickly eliminated and the aggravation of the condition is prevented.

The greatest efficiency is observed when prescribing a medication at an early stage of a pathological condition. It inhibits the development of viruses after their penetration into the cell, but does not have a pronounced negative effect on the cell itself, which is its advantage.

When prescribing a medicine, immediately when the first signs of a pathological condition appear, the development of the pathological process stops, and the recovery period is also shortened. In the absence of drugs with antiviral effect, the recovery period is prolonged and the risk of complications from the respiratory system increases.

The agent disrupts metabolic processes in viruses. As a result, there is a slowdown or complete cessation of the transfer of information to cell membranes. This action prevents viruses from damaging many cells.

The complex effect of the ingredients on the body makes the product quite effective and relatively safe for patients when used correctly.

When the tablet enters the digestive tract, it dissolves and the active substance is absorbed through the walls of the small intestine.

After that, the active ingredient spreads through the systemic circulation and carries out a therapeutic effect. Rimantadine circulates through the blood for a long period, which is considered its advantage and allows it to be used for the prevention of viral pathologies.

The ingredient binds well to blood plasma proteins, but its bioavailability is approximately 40%. Experts note that the concentration of the substance in the patient's nasal secretion is 50% higher than its amount in the blood. This explains the high efficiency in the prevention of influenza.

The processing of the active ingredient is carried out in the liver, where it breaks down into metabolites. The excretion of the active ingredient occurs with the help of the kidneys. This method evacuates about 85% of metabolites. The rest is excreted unchanged, mainly through the kidneys. A slight excretion of metabolites with feces is possible.

Despite the long circulation of the basic substance in the blood, its accumulation in tissues and plasma does not occur. Only in patients with severe kidney pathologies, there is a slowdown in the excretion of the ingredient and a slight accumulation of it in the body. In such disorders, the drug is prescribed less often, which is associated with an increased risk of complications.

In elderly patients, the processing of a substance in the body is also carried out slowly, which has almost no effect on the therapeutic effect provided.
