The measurement will be made according to the instructive BE-IT-005 Medición de signos vitales)
* Normal electrocardiogram \[ECG\]. No abnormalities are allowed, even though they are not relevant (PR, QRS, QT, QTcF should be within normal range; no conduction abnormalities are allowed, etcetera (etc)
* All values in blood and urine tests should be within the normal range or showing no clinically relevant deviation as judged by the Investigator
* Participants with thyroid panel results within normal range (T3 and T4 total and free, as well as thyroid-stimulating hormone (TSH) should be within the normal range)

* History of cardiovascular, renal, liver, metabolic, gastrointestinal, neurological, endocrine, hematopoietic (any type of anemia) conditions, mental disorder or organic abnormalities that may affect the pharmacokinetic study of the study drug
* Any medical or surgical condition, including findings in the medical history or clinical assessment prior to the study, that in the opinion of the investigator poses a risk or contraindication for the participants participation in the study and may affect the study objectives, conduct or analysis
* History or presence of alcohol abuse (average daily intake not higher than 3 units or weekly intake not higher than 21 units; 1 unit is equivalent to 340 mililiter (mL) of beer, 115 mL of wine or 43 mL of prepared drinks), psychoactive substances or chronic use of drugs
* Participants who have been exposed to agents knows by inducing or inhibiting the liver enzymatic systems or who have taken potentially toxic drugs within the last 30 days to the study start-up
* Participants who take drugs affecting the metabolism of the thyroid hormone, such as: oral contraceptives, hormonal implants, parenteral hormones, steroids, anabolic drugs, androgens, etc., or any drug affecting the levothyroxine's bioavailability such as the proton pump inhibitors or multivitamins, nutritional supplements or herbal products that may affect the study, except for the occasional use of paracetamol
