Pharmacological properties

Pharmacodynamics

Dimetindene maleate is a derivative of phenindamine, an antagonist of histamine at the level of H1-receptors. It has anti-allergic and anti-itching effects. Due to the active substance of the medicinal product - dimetindene maleate - after applying the gel to the skin, itching and irritation that accompany skin allergic reactions are reduced. The preparation also has local anesthetic properties and cools the skin when applied.

When applied topically, the gel, due to its specially designed base, quickly penetrates the skin and starts acting within a few minutes. The maximum effect is achieved within 1-4 hours.

Pharmacokinetics

The systemic bioavailability of the active substance is 10%.

Clinical characteristics

Indications

Skin itching, for example, with insect bites, non-extensive sun erythema, uncomplicated small skin burns, and allergic irritation of small skin areas.

Contraindications

Interaction with other medicinal products and other types of interactions

No studies on the interaction of the medicinal product have been conducted; however, since the systemic absorption of dimetindene maleate when using the Dimetindene gel is extremely low, interaction with other medicinal products is unlikely.

In such cases, the use of the preparation is possible only under the supervision of a doctor.
