8 Clinical Trials for Various Conditions
This research study will evaluate the effect of liver disease on the pharmacokinetics (the breakdown of the drug in the body) of parallel-group, multiple oral doses nalbuphine extended release (NAL ER), tablets in people with liver disease (mild, moderate and severe), compared to people with normal liver function. The study will also test the safety and tolerability of the NAL ER, when it is given to subjects with mild, moderate and severe liver disease, compared to subjects with normal liver function. This protocol will also study the effects of this drug on itching in liver disease subjects if they report some itching prior to taking part in this study.
The primary objectives of the study are to evaluate the effects of two doses of nalbuphine HCl ER tablets on the change from baseline in the worst itch Numerical Rating Scale (NRS) in patients with prurigo nodularis and to evaluate the safety and tolerability in the study population.
The primary objective of the study is to evaluate the overall safety of nalbuphine HCL ER tablets during a treatment period of up to 24 weeks.
The primary objectives of the study to evaluate the effects of two doses of nalbuphine HCl ER tablets on the change from baseline in the worst itch Numerical Rating Scale (NRS) in hemodialysis patients with moderate to severe uremic pruritus and to evaluate the safety and tolerability in the study population.
This is an open-label, sequential 2 cohort, intramuscular injection study in healthy volunteers. The study will enroll approximately 24 healthy volunteers to examine the safety, pharmacokinetics, and bioavailability after intramuscular injection of NALDEBAIN ER Injection and nalbuphine injection.
In previous clinical studies of post-surgical pain the investigators found that nalbuphine (Nubain), a narcotic pain killer, relieves pain more effectively when combined with low-dose naloxone (Narcan), a drug that is used to treat narcotic overdose. This finding was particularly true in men. The purpose of this study is to find out if nalbuphine combined with naloxone is more effective in relieving experimentally produced pain than either drug alone. A second reason for this study is to find out if study medications work more effectively in women or in men. Subjects will come to the University of California at San Francisco (UCSF) Clinical Research Center (CRC) for 4 study visits. The first visit will be a 2-hour screening to assess the subject for study eligibility. During the other three visits, the investigators will use a thermal stimulating device to produce temporary, non-injurious skin sensitivity that subjects will feel as painful. Changes in pain will be measured following the intravenous (i.v.) administration of study drugs. Three drug combinations will be administered, a different one each visit: 1) nalbuphine 5 mg and naloxone 0.4 mg , 2) naloxone 0.4 mg and saline (an inactive solution), nalbuphine 5 mg and saline. These drug combinations will be administered in random order; all subjects will receive all three combinations.
Patients with chronic masticatory muscle pain (i.e., pain greater than three months) or patients with burning mouth syndrome participate in this study. The aim of the study is to compare the pain killing effectiveness of nalbuphine, a narcotic pain killer, administered with either placebo or naloxone, a drug used to treat opiate overdose. A second goal is to determine if there are sex differences in these two drug regimens. Drugs will be administered with single-use intranasal spray devices. All participants will receive two sprays (one spray per nostril). One of the two sprays will be nalbuphine (5 mg). The other spray will be naloxone in half the participants and placebo in the other half.
Intrapartum epidural analgesia has been associated with adverse breastfeeding outcomes. One potential mechanism involves transfer of epidural fentanyl across the placenta and neonatal blood-brain barrier, where it can subsequently attenuate neonatal exhibition of feeding behaviors, such as latching and swallowing, during the immediate postpartum period. Vigorous feeding behavior during the first days of life is a significant predictor of long-term breastfeeding success at 3 and 6 months. In a randomized, controlled, double-blinded study, neonatal Neurologic and Adaptive Capacity Scores (NACS) were significantly lower when mothers received \>150 mcg epidural fentanyl versus bupivacaine-only analgesia, and mean umbilical cord fentanyl concentration was significantly higher in the \>150 mcg versus \<150 mcg group. The investigators hypothesize that epidural fentanyl-bupivacaine analgesia is significantly associated with decreased breastfeeding rates at hospital discharge and with neonatal deficits in latching onto the breast and swallowing during the first three hours of life, and that a significant dose-response relationship exists with respect to total micrograms fentanyl infused. The investigators will perform a prospective cohort study of all parturients age 18+ at UHCMC over a three-month period, excluding those with multiples gestation, Cesarean section, or neonatal intensive care unit admission. From patient charts, the investigators will record the following variables: number of neonates delivered; type of delivery (spontaneous vaginal / operative vaginal / Cesarean section); whether the neonate was admitted to the intensive care unit; the mother's age, height, weight, gravity, parity, intention to breast-feed at the time of hospital admission, number of children previously breast-fed, and ethnicity; gestational age at the time of delivery; administration of oxytocin for labor augmentation and in what quantity; duration of active labor; antibiotic administration; neonatal APGAR scores at 1 and 5 minutes postpartum; and whether opioids or antibiotics were administered before and/or after the delivery and at what exact time. We will also record whether each patient received an epidural during labor and, if so, the duration of this epidural infusion and the total micrograms fentanyl delivered; neonatal feeding behavior as quantified by the LATCH scores assigned to each breast-feeding interaction that occurs on the postpartum care floor; whether the mother is breast-feeding her baby at the time of discharge from the hospital, and if not, then her primary reason for not doing so (as communicated during the standard postpartum lactation consultation); and how long mother and baby stayed in the hospital post-delivery.
