Fluidasa is a medication designed to relieve respiratory distress. It is used in cases of acute and chronic bronchitis, in both adults and children.
The active ingredient is called mepifilina, a combination of two substances: a xanthine and an H1 antihistamine. Together they act as a bronchodilator, helping the bronchi to relax and allowing air to pass more easily.
It also helps air flow more easily to the lungs. Each milliliter of the syrup contains 5 mg of mepifilline. It also includes sorbitol, sweeteners, and preservatives, such as parahydroxybenzoates.
Who is it suitable for?
It is indicated for people with bronchitis, whether occasional or chronic. It can be used in both children and adults, always following the appropriate dosage. Fluidasa is not a mucolytic. Its purpose is to combat bronchoconstriction, when the bronchi narrow and make it difficult to breathe.

What dose is recommended?
The amount depends mainly on weight and age. In general, the daily dose is divided into four administrations. Children under 5 years: 1 to 2 measures of 5 ml, three or four times a day.
