Kriterijai | INCLUSION CRITERIA: Active duty military Current in their medical screening EXCLUSION CRITERIA: Upper respiratory tract infection or influenza Have had a reaction to Ibuprofen, aspirin or other Non-Steroidal Anti-inflammatory Drugs (NSAIDs). Stayed the night at an altitude of greater than 6,700 feet within the last 7 days Headache at baseline Have altitude sickness or more than one mild symptom of any severity on the Lake Louise Questionnaire including headache, poor appetite, nausea, vomiting, fatigue, weakness, dizziness, and/or poor sleep (insomnia) Low blood oxygen or low oxygen saturation (<90%) Pregnant or cannot exclude the possibility of being pregnant, or have missed menses by over 7 days. Have taken any of the following in 48 hours preceding enrollment: acetazolamide/Diamox, steroids (dexamethasone/Decadron, prednisone), theophylline, or diuretics such as Lasix Have taken any of the following within 12 hours preceding enrollment: Ibuprofen/Motrin, Naprosyn/Naproxen/Aleve, aspirin, or Acetaminophen/Tylenol. Have taken any other medication that may be known to have potential for drug-drug interactions with ibuprofen, including (but not limited to): ACE-inhibitor antihypertiensives, thiazide diuretics, furosemide, lithium, methotrexate, and H-2 Agonists. Have any medical conditions which may make participation hazardous (*by self-report which can be clarified before enrollment with the study physicians as necessary), including: - Heart disease - Congestive heart failure, heart attack in the last month or severe coronary artery disease, or significant heart valve problems or other congenital problems. - Lung disease - Restrictive lung disease, chronic obstructive pulmonary disease (COPD), severe obstructive sleep apnea, or pulmonary hypertension of any cause. - Neurological disorders - Hydrocephalus, history of brain tumor, history of severe brain trauma or coma, pseudotumor cerebri, or severe uncontrolled headaches/migraine disorder (as diagnosed by a doctor). - Gastrointestinal - Known stomach ulcer or history of gastrointestinal bleeding. - Blood disorders - Anemia, leukemia, or other coagulopathies of any kind. - Kidney disease - Kidney failure or other known kidney disease. General - The Principal Investigator and co-investigator reserve the right to exclude a potential participant with conditions that in their judgment are not listed above, but which would reasonably represent concern for the participant's health and welfare, including (but not limited to) conditions that may directly antagonize mechanisms of acclimatization to altitude, organ failure, metastatic/malignant neoplasm, space-occupying brain lesions or diagnoses typically known to raise intracranial pressure, and disorders that are likely to antagonize adequate respiration, blood oxygenation, and/or circulation. |
