Sporadic amyotrophic lateral sclerosis (ALS) is believed to be a complex disease in which multiple exogenous and genetic factors interact to cause motor neuron degeneration. Elucidating the association between medical conditions prior to the first symptoms of ALS could lend support to the theory that specific subpopulations are at risk of developing ALS and(More)
The human body is critically dependent on the ventilatory control system for adequate uptake of oxygen and removal of carbon dioxide (CO2). Potent opioid analgesics, through their actions on μ-opioid receptor (MOR) expressed on respiratory neurons in the brainstem, depress ventilation. Opioid-induced respiratory depression (OIRD) is potentially life(More)
BACKGROUND Opioid-induced respiratory depression is potentially lethal. GAL021 is a calcium-activated potassium (BKCa) channel blocker that causes reversal of opioid-induced respiratory depression in animals due to a stimulatory effect on ventilation at the carotid bodies. To assess in humans whether GAL021 stimulates breathing in established opioid-induced(More)
Opioid-induced respiratory depression (OIRD) is a potentially fatal complication of treatment with opioids. Little is known about patient- and case-related factors associated with OIRD. One-hundred-and-five available case reports on OIRD in 134 patients (12 years and older) in the perioperative, obstetric or emergency care setting, published since 1980,(More)
BACKGROUND Respiratory depression is a potentially fatal complication of opioid use, which may be exacerbated by simultaneous ethanol intake. In this three-way sequential crossover dose-escalating study, the influence of coadministration of oral oxycodone and intravenous ethanol was assessed on resting ventilation, apneic events and the hypercapnic(More)
Doxapram is an analeptic that induces ventilatory stimulation and increases blood pressure and cardiac output (CO). Its mechanism of action is the blockade of background K+ -channels expressed on type 1 carotid body cells. In the randomized controlled trial, the authors explored the role of the increase in CO by doxapram (plasma concentration (Cp)(More)
Opioid-induced respiratory depression (OIRD) is a serious and potentially life-threatening complication of opioid overdose, abuse, and misuse. An option to avert OIRD is to treat patients on strong opioids with respiratory stimulants that do not interact with the opioid system and consequently do not compromise opioid analgesic efficacy. The BK-channel(More)
