Pirbuterol is a beta-2 adrenergic bronchodilator. In vitro studies and in vivo pharmacologic studies have demonstrated that pirbuterol has a preferential effect on beta-2 Adrenergic receptors compared with isoproterenol. While it is recognized that beta-2 adrenergic receptors are the predominant receptors in bronchial smooth muscle, data indicate that there is a population of beta-2 receptors in the human heart, existing in a concentration between 10-50%. The precise function of these receptors has not been established. The pharmacologic effects of beta adrenergic agonist drugs, including pirbuterol, are at least in proof attributable to stimulation through beta adrenergic receptors of intracellular adenyl cyclase, the enzyme which catalyzes the conversion of adenosine triphosphate (AlP) to cyclic-3†,5†-adenosine monophosphate (c-
Pitolisant is a selective antagonist or inverse agonist of the histamine H3 receptor used to treat type 1 or 2 narcolepsy. Narcolepsy is a chronic neurological disorder that affects 1 in 2,000 individuals and is characterized by excessive daytime sleepiness, abnormal REM sleep manifestations, sleep paralysis and hypnagogic hallucinations. About 60-70% of patients with narcolepsy experience cataplexy, which is a sudden loss of muscle tone triggered by positive or negative emotions. Histaminergic neuron signalling in the brain plays a role in maintaining wakefulness; by blocking histamine autoreceptors, pitolisant enhances the activity of histaminergic neurons, as well as increasing the signalling of other neurotransmitters in the brain. In a European clinical trial of adult patients with narcolepsy, there was a reduction in the Epworth Sleepiness Scale (ESS) score from pitolisant therapy compared to placebo. The therapeutic effectiveness of pitolisant was comparable to that of [modafinil]. Pitolisant therapy was also effective in treating refractory sleepiness in adolescent patients with narcolepsy, where it decreased ESS score and increased the mean sleep onset latency. Adolescent patients with cataplexy also experienced a slight improvement in the frequency and severity of symptoms ; however, the safety of use in adolescent or paediatric patients have not been established with pitolisant. Commonly marketed under the trade name Wakix, oral pitolisant was approved by the EMA in 2016 for the treatment of narcolepsy with or without cataplexy. FDA approved the use of pitolisant in 2019 for excessive daytime sleepiness (EDS) associated with narcolepsy in adults.
