Official title
Pharmacokinetic Properties of Fondaparinux Sodium in Morbidly Obese Volunteers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Morbidly obese individuals are at high risk for potentially life threatening blood clots around the time of abdominal surgical procedures. Fondaparinux sodium (Arixtra) is an FDA- approved medication used in the prevention of deep venous thrombosis (DVT) at the time of orthopedic or abdominal surgery, as well as for the treatment of DVT and pulmonary embolism (PE). As with many medications, therapeutic dosages have not been fully investigated for the morbidly obese population. Our goal is to study the therapeutic blood levels, after 2 different dosages of the medication are given to morbidly obese volunteers. We will recruit 21 morbidly obese (Body Mass Index (BMI) \> 35) individuals who are in the evaluation process for bariatric surgery. They will be divided into 7 groups: 3 participants with BMI 35 - 39.9, 3 with a BMI of 40 - 49.9, 3 with a BMI of 50 - 59.9, 3 with a BMI \> 60, 3 with a weight of 100 - 149 KG, 3 with a weight of 150 - 199 KG and 3 with a weight of 200 - 249 KG. Participants will be administered two different doses of the medication with a 2-week interval in between, then blood will be drawn in various intervals throughout the next 48 hours to see which dose provides the best therapeutic levels. Participants will be monitored closely for any side effects or complications.
