Tsetrin or Erius, the choice of drug

Both Eirus and Cetrin are effective antihistamines. Act almost the same way, block H1-histamine receptors. Both drugs are well absorbed from the digestive tract. Eating does not affect the volume of the substance, but lengthens this process.

The main difference is that the maximum concentration in the blood when taking Cetrin is reached 3 times faster. However, the duration of Erius is about 3 times longer. Both drugs are used in the early and late stages of allergies. Eliminate itching, swelling, redness, and other allergy symptoms. Since Tsetrin has a half-life less than that, sometimes the daily dosage is divided into 2 doses.

Cetrin is able to reduce psychomotor reactions, as well as cause drowsiness. Therefore, after taking it, it is recommended to refrain from driving a car.

Admission Erius significantly less suppresses the central nervous system. Cetrin is able to accumulate in the tissues of the body even after discontinuation of the drug.

For children, starting from 6 months old, Erius syrup is suitable. Cetrin can be prescribed only from the age of two.

The following positive aspects of Erius can be noted:

  1. It has no effect on the central nervous system.
  2. It is enough to take 1 time per day.
  3. Reception is possible for children from 6 months.
  4. It has a long action.

Positive aspects of Cetrin:

  • Affordable price.
  • It has a speed.
