Arm Intervention/treatment
Experimental: Lactase EUF
1 oral tablet of the test drug before breakfast, lunch and dinner for 42 consecutive days

Primary Outcome Measures :
  1. Hydrogen value in the expired air [ Time Frame: 03 times ]
    Hydrogen value in the expired air for 3h after the patient exposure to the standardized Lactose 25g dose with interventional exogenous Lactase (comparative and test drugs).

Secondary Outcome Measures :
  1. Signs and Symptoms Diary [ Time Frame: 42 days ]
    • Signs and Symptoms Diary, registered for the period between V0 and V1 / V1 and V2;
    • The Specific Symptom Score registered during the tests of hydrogen in the expired air;
    • Global Evaluation of the Treatment Tolerance by the patient and the investigator; Frequency of adverse events noted.
