CONCLUSIONS: The clonidine adhesive patch is effective and safe for tic disorders.

Clonidine for the treatment of supine hypertension and pressure natriuresis in autonomic failure. [2006.03]
Patients with autonomic failure are disabled by orthostatic hypotension, which can be worsened by the nighttime pressure natriuresis induced by associated supine hypertension... These results are consistent with residual sympathetic tone contributing to supine hypertension in autonomic failure, which can be targeted with clonidine to decrease BP and nocturnal natriuresis.

Opioid detoxification with buprenorphine, clonidine, or methadone in hospitalized heroin-dependent patients with HIV infection. [2003.04.01]
With the growing role of intravenous drug use in the transmission of HIV infection, HIV-infected patients frequently present with comorbid opioid dependence. Yet, few empirical evaluations of the efficacy and consequences of opioid detoxification medications in medically ill HIV-infected patients have been reported...

Clinical Trials Related to Catapres-TTS (Clonidine Transdermal)

Epidural Fentanyl-bupivacaine Versus Clonidine-bupivacaine for Breakthrough Pain in Advanced Labor [Not yet recruiting]
Epidural analgesia is widely regarding as the most effective analgesic strategy for labor pain. Modern practice is to utilize dilute local anesthetics as a continuous infusion along with an opioid, e. g., our common "recipe" of 12 ml/hr of 0. 0625% bupivacaine with 2 micrograms/ml fentanyl, after the initial dose to maintain patient comfort until delivery. This dose of the infusion often provides adequate comfort without interfering with the mobility of the patient and her ability to effectively push during delivery. However, this low dose epidural infusion strategy often results in recurrence of pain after an initial pain free period.

This breakthrough pain is treated by administering small boluses of analgesics via the epidural catheter. The pain occurring in labor is initially of visceral origin and is mediated by pain fibers originating from the low thoracic and upper lumbar segments of the spinal cord. As labor progresses to the late first phase (also known as transitional stage), pain sensations originating from the distension of the pelvic floor, vagina and perineum adds a somatic component to labor pain. This type of breakthrough pain is often difficult to treat.

Although requests from patients to alleviate late stage breakthrough pain are common, no one knows the most effective strategy for pain management in this stage of labor. This study is designed to compare the efficacy of two treatments for controlling late first stage breakthrough pain during labor with an epidural infusion in place: clonidine-bupivacaine versus fentanyl-bupivacaine.

Women who have labor epidural analgesia in place will be enrolled to be randomized if and when they present with breakthrough pain in the late first stage or second stage of labor (≥ 8 cm dilated). They will receive 8 ml of a solution containing 10 mg bupivacaine and 75 micrograms of either fentanyl (an opioid or "narcotic") or clonidine (an "alpha-2 agonist known to be effective as an epidural analgesic).

Pain relief, labor progress and outcome will be assessed to compare fentanyl versus clonidine.

It is the hypothesis of this study that clonidine added to bupivacaine is a better analgesic than fentanyl added to bupivacaine for breakthrough pain in advanced labor.

The Use of Clonidine in Pain and Anxiety Associated With Acute Burn Injury in Children [Recruiting]
Some of the children who suffer acute burn injury do not have adequate pain and anxiety management with the current regimen of scheduled opiates (morphine) and benzodiazepines (lorazepam). Other children have significant side effects or contraindications, such as constipation or over sedation, when taking these medications. Clonidine is known to reduce the need for morphine in the management of postoperative pain. The addition of clonidine to the pharmacological treatment of burn wound pain offers a possible adjunct to the standard opiate and benzodiazepines regimen. Clonidine has been used in children in both on a short-term basis (such as postoperative pain management) and on a long-term basis (such as the treatment of attention deficit hyperactivity disorder (ADHD)). This study tests the hypothesis that clonidine in a dose of 5 ug/kilo every 8 hours will be a useful adjunct to the management of pain and anxiety in the acutely burned child. All children will be treated by protocol with morphine (0. 03mg/kilo) q4hr prn pain and lorazepam (0. 03 mg/kilo) q 4 hours prn anxiety. In addition, after informed consent is obtained the children will be randomized to the addition clonidine or placebo. Pain and anxiety will be assessed using standard instruments blind to the medication being used on a daily basis Also the total dose of morphine and lorazepam during the 10 days of added clonidine or placebo will be recorded.. The pain rating, anxiety ratings, total morphine dose, and total lorazepam dose will be compared between the placebo and clonidine groups with a Student's t test. Once the blind is broken the child will be allowed to remain on the clonidine if it is beneficial. The second year of the grant will expand the age groups down to younger children and also begin to gain information about the effect of clonidine on the hypermetabolic state secondary to burn injury.

PeriOperative ISchemic Evaluation-2 Trial [Recruiting]
Major surgeries not involving the heart are common, and major heart problems during or after such surgeries represent a large population health problem. Few treatments to prevent heart problems around the time of surgery have been tested. There is encouraging data suggesting that small doses of Acetyl-Salicylic Acid (ASA) and Clonidine, which are two medications, given individually for a short period before and after major surgeries may prevent major heart problems. The POISE-2 Trial is a large international study to test if ASA and Clonidine can prevent heart attacks and deaths from heart problems around the time of surgery.

Clonidine to Treat Iatrogenic-induced Opioid Dependence in Infants [Not yet recruiting]
Thousands of critically ill infants (and children) are exposed to opioids and benzodiazepines to achieve sedation and analgesia as part of routine care in neonatal and pediatric intensive care units. While the use of these agents are undisputedly beneficial in reducing pain and anxiety, improving ventilation, reducing pulmonary vascular resistance and improving outcomes; the consequence is often the development of tolerance and

physiologic dependence - similar to prenatal exposure from these same classes of drugs. The

investigators have recently reported the results of randomized placebo control trial showing that the addition of clonidine (central alpha 2 agonist) to tapering doses of opioids was efficacious and safe in treating opioid dependence in infants who had moderate to severe neonatal abstinence syndrome from prenatal drug exposure to opioids. Currently, the investigators propose to perform a double-blind, randomized placebo control trial in a cohort of critically ill infants without prenatal drug exposure at Johns Hopkins Hospital to test the overall hypothesis that early addition of clonidine to a cohort of critically ill neonates on mechanical ventilation who are receiving opioids and benzodiazepines for analgesia and sedation will be efficacious and safe in reducing both the incidence and severity of withdrawal symptoms (NICU-NAS); as well as, reducing the time to complete sedative and analgesic drug detoxification. The hypothesis will be tested by addressing 2 specific aims that will determine: 1) the efficacy and safety of clonidine in critically ill infants, and 2) pharmacokinetics and pharmacodynamics using population-based pharmacokinetics in this vulnerable infant population who have only been exposed to these drugs as part of their routine care. Many "standard of care practices" are incorporated in neonatal and pediatric care prior to evidence based studies. This proposal will fill a much needed gap in translating what the investigators have learned about basic mechanisms mediating dependence and withdrawal to proven therapies for vulnerable pediatric populations.

Pharmacological Interaction Between Clonidine and Methylenedioxymethamphetamine (MDMA) [Recruiting]
The purpose of this study is to determinate the effect of a pre-treatment with centrally acting alpha2-receptor agonist clonidine on the pharmacodynamics and pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA, "Ecstasy"). The investigators hypothesize that clonidine will attenuate the subjective and cardiovascular response to MDMA.
