Primary Outcome Measures:
  • Hydrogen value in the expired air [ Time Frame: 03 times ] [ Designated as safety issue: No ]
    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:
  • Signs and Symptoms Diary [ Time Frame: 42 days ] [ Designated as safety issue: Yes ]

    • 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.
