Allocation: RANDOMIZED
Intervention model: PARALLEL
Primary purpose: BASIC_SCIENCE

Brief summary: The goal of this clinical pilot study is to evaluate the pharmacokinetic profile of magaldrate in a group of 10 healthy women, after the administration of a 10 mL drug suspension containing 500 mg of sodium alginate, 267 mg of sodium bicarbonate, 800 mg of magaldrate and 120 mg of simeticone. The main question it aims to answer is the amount of magnesium and/or aluminum, if any, absorbed into the plasma from this oral administration.

Participants will take the medication 30 minutes after a standard breakfast. Both groups of participants will take the standard meal but one group will take the medication and the other one won't.

Researchers will compare the levels of both ions in plasma in a group to see if there is any absorption, quantifying the basal plasma levels and comparing with the levels obtained after the meal and the medication, when it applies.

* Have any current symptoms or illness, acute or chronic, under monitoring or treatment, significant at the discretion of the investigator/responsible physician
* Electrocardiographic findings not recommended at the doctor's discretion to participate in the study
* Have the results of the laboratory tests performed in the clinical evaluation of recruitment outside the values considered normal, in accordance with the reference values stipulated by the clinical analysis laboratory, unless they are considered not clinically significant by the researcher /responsible doctor
