Methadone is a potent synthetic analgesic that works as a full µ-opioid receptor (MOR) agonist and N-methyl-d-aspartate (NMDA) receptor antagonist. As a full MOR agonist, methadone mimics the natural effects of the body's opioids, endorphins, and enkephalins through the release of neurotransmitters involved in pain transmission. It also has a number of unique characteristics that have led to its increased use in the last two decades; in particular, methadone has a lower risk of neuropsychiatric toxicity compared to other opioids (due to a lack of active metabolites), minimal accumulation in renal failure, good bioavailability, low cost, and a long duration of action.[F4685,F4688,F4691,A185885,A185900,A185903] Due to its unique mechanism of action, methadone is particularly useful for the management of hard to treat pain syndromes
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-AMP). Increased c-AMP levels are associated with relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, especially from mast cells.
