OTC NCT00011063 ↗ Effect of Ginkgo Biloba on Phenytoin Elimination Completed National Institutes of Health Clinical Center (CC) Phase 1 2001-02-01 This study will examine how the herbal remedy ginkgo biloba may affect the body's elimination of other medicines. Many people take ginkgo biloba to improve memory, mental alertness and overall feeling of well being. Since this product is considered a food supplement and not a drug, it is not subject to the rigorous pre-market testing required for prescription and over-the-counter (OTC) drugs. As a result, information has not been collected on possible interactions between ginkgo biloba and other medications. This study will look at how ginkgo biloba affects the elimination of phenytoin-a medication used to treat patients with seizures. Normal healthy volunteers 21 years of age or older may be eligible for this 40-day study. Candidates will provide a medical history and undergo a physical examination and routine blood tests. Women of childbearing age must use a reliable form of birth control other than oral contraceptives ("the pill"). For at least 2 weeks before the study and throughout its duration, study participants may not have any of the following: 1) medications that can affect platelet function (e.g., aspirin, Motrin, Advil, Nuprin, ibuprofen, etc.); 2) alcoholic beverages; 3) grapefruit and grapefruit juice; and 4) all medications except those given by study personnel. On day 1 of the study, subjects take one 500-mg dose of phenytoin at 8:00 A.M.. On an empty stomach. (Subjects fast the night before taking the phenytoin and are allowed to eat breakfast 2 hours after the dose). Blood samples are drawn just before dosing and again at 0.5, 1, 1.5, 2, 4, 6, 8, 10, 12, 24, 32, 48, 72 and 96 hours after the dose. Blood drawn on this first study day is collected through a catheter (small plastic tube) placed in a vein to avoid multiple needlesticks. After the 12-hour sample is collected, the subject goes home and then returns to the clinic for the remaining blood draws, which are taken by direct needlestick. When the blood sampling is completed, subjects begin ginkgo therapy. The NIH Clinical Center provides participants a supply of 60-mg capsules of ginkgo to take twice a day (at 8 A.M. and 8 P.M..) for 4 weeks. At the end of the 4 weeks, subjects are given a second dose of phenytoin as described above and repeat the blood sampling procedure. Subjects continue taking ginkgo during this second phenytoin study.
OTC NCT00267293 ↗ Ibuprofen Alone and in Combination With Acetaminophen for Treatment of Fever Completed Children Youth and Family Consortium Phase 4 2006-01-01 Currently, when a child has fever either ibuprofen (e.g. Motrin, Advil) or acetaminophen (e.g. Tylenol) is given. Both Ibuprofen and Acetaminophen are approved for over the counter use for treatment of fever by the Food and Drug Administration (FDA). This study hopes to determine whether giving both medications together is better than giving one medication alone for the treatment of fever.
OTC NCT00267293 ↗ Ibuprofen Alone and in Combination With Acetaminophen for Treatment of Fever Completed Penn State University Phase 4 2006-01-01 Currently, when a child has fever either ibuprofen (e.g. Motrin, Advil) or acetaminophen (e.g. Tylenol) is given. Both Ibuprofen and Acetaminophen are approved for over the counter use for treatment of fever by the Food and Drug Administration (FDA). This study hopes to determine whether giving both medications together is better than giving one medication alone for the treatment of fever.
OTC NCT04040465 ↗ Asprin Dosing Estimator in Healthy Adults Recruiting University of Colorado, Denver Early Phase 1 2021-02-15 Understanding sources of variability in human drug dosing is important to the beneficial and safe use of any drug. Understanding and applying the science of individualizing a drug dose to a patient is called precision medicine. Aspirin is one of the oldest most utilized medications for its ability to lower fever, relieve pain, and to reduce the stickiness of platelets (tiny blood cells that help your body form clots to stop bleeding. Aspirin dosing is currently the same for all patients and is not individualized. In the last century, aspirin has shown benefit in reducing cancer, stroke, and preventing cardiovascular events after one has already had a heart attack or stroke. Previous human studies have not found consistent positive effects of aspirin when dosed by body weight. Therefore, how should aspirin be dosed in 2019? Aspirin resistance is the failure of aspirin to reduce platelet stickiness and thin the blood and most importantly, is associated with higher risk of heart attacks and strokes. Aspirin resistance may occur due to not taking aspirin on a regular basis, differences in how platelets behave in some persons, use of over the counter pain medicines like Motrin®, reduced amount of drug in the body, and/or a lack of being able to predict a dose for a certain individual. To find out the best way to dose aspirin, the investigators propose to study healthy volunteers (persons without any known disease) with different ages and body sizes to see if aspirin blood levels are tied to platelet stickiness. This information will be used to mathematically build a computer-based picture of aspirin dosing that will help physicians pick the best dose of aspirin for each patient. The investigators will then extend studies for the aspirin dose estimator to be used in other countries in people with heart problems and stroke, recording future events in a randomized (i.e., coin toss) manner, to determine if the ability of the aspirin dose estimator to prevent future heart attacks and stroke compared to people receiving aspirin doses that were chosen without the estimator.

NCT00002276 ↗ The Effects of AZT and Ibuprofen on HIV-Infected Patients With Hemophilia Completed University of Pittsburgh N/A 1969-12-31 To determine if platelet dysfunction and/or pharmacologic drug interaction occurs in patients taking both AZT and ibuprofen, which might account for enhanced bleeding tendency.
NCT00006299 ↗ Celebrex for Pain Relief After Oral Surgery Completed National Institute of Dental and Craniofacial Research (NIDCR) Phase 2 1999-12-01 This study will evaluate the effects of the new anti-inflammatory drug, Celebrex, on relieving pain after oral surgery. It is also designed to assess the drug's selective inhibition of a chemical called cyclooxygenase-2 and not its closely related form, cyclooxygenase-1. This selective inhibition allows pain alleviation without the adverse side effects (e.g., bleeding and stomach upset) often associated with anti-inflammatory drugs. Healthy volunteers who require removal of their third molars are eligible for this study. Participants will have oral surgery for tooth extraction after receiving a local anesthetic (lidocaine) in the mouth and a sedative (midazolam) through an arm vein. On the evening before and 1 hour before surgery, patients will be given a dose of either the standard anti-inflammatory drug ibuprofen (Advil, Nuprin, Motrin), or Celebrex, or a placebo (a pill with no active ingredient). After surgery, a small piece of tubing will be placed in each extraction site and tied to an adjacent tooth to hold it in place. Samples will be collected from the tubing to measure chemicals involved in pain and inflammation. Patients will stay in the clinic for up to 6 hours after surgery while the anesthetic wears off and will complete pain questionnaires. During that time, they may receive acetaminophen plus codeine (Tylenol 3), if needed, for pain. The tubing then will be removed and the patient discharged with standard pain medication.
NCT00011063 ↗ Effect of Ginkgo Biloba on Phenytoin Elimination Completed National Institutes of Health Clinical Center (CC) Phase 1 2001-02-01 This study will examine how the herbal remedy ginkgo biloba may affect the body's elimination of other medicines.

Subjects continue taking ginkgo during this second phenytoin study.
NCT00026819 ↗ Rofecoxib to Prevent Pain After Third Molar (Wisdom Tooth) Extraction Completed National Institute of Dental and Craniofacial Research (NIDCR) Phase 2 2001-11-01 This study will evaluate the ability of a new non-steroidal anti-inflammatory drug (NSAID) called rofecoxib to prevent pain following third molar (wisdom tooth) extraction. The Food and Drug Administration approved rofecoxib in 1999 to treat the symptoms of arthritis, menstrual cramps, and pain. Healthy normal volunteers between 16 and 35 years of age in general good health who require third molar (wisdom tooth) extraction may be eligible for this study. Candidates will be screened with a medical history and oral examination, including dental x-rays as needed to confirm the need for third molar removal. Participants will have all four wisdom teeth extracted, and a biopsy (removal of a small piece of tissue) will be taken from the inside of the cheek around the area behind the lower wisdom tooth. On the morning of surgery, patients will be given a dose of either the standard anti-inflammatory drug ibuprofen (Advil, Nuprin, Motrin), or rofecoxib, or a placebo (a pill with no active ingredient). Before surgery, they will be given a local anesthetic (lidocaine) in the mouth and a sedative (midazolam) through an arm vein. After the surgery, patients will remain in the clinic for up to 4 hours to monitor pain and the effects of the drug. Patients will complete pain questionnaires. Patients whose pain is unrelieved an hour after surgery may request and receive morphine intravenously (through a vein). After 4 hours, patients will be discharged with additional pain medicines (Tylenol with codeine and the study drug) and instructions for their use. They will also be given a pain diary to record pain ratings and medications taken at home. A clinic staff member will telephone patients at home the morning after surgery to ensure they are rating their pain intensity at the proper time and are taking their medications as instructed. Patients will return to the clinic 48 hours after surgery with the pain diary and pain relievers. At this visit, another biopsy will be taken under local anesthetic.
NCT00267293 ↗ Ibuprofen Alone and in Combination With Acetaminophen for Treatment of Fever Completed Children Youth and Family Consortium Phase 4 2006-01-01 Currently, when a child has fever either ibuprofen (e.g. Motrin, Advil) or acetaminophen (e.g. Tylenol) is given. Both Ibuprofen and Acetaminophen are approved for over the counter use for treatment of fever by the Food and Drug Administration (FDA).
