DrugDrug NameDrug Description
DB00748CarbinoxamineCarbinoxamine is a first generation antihistamine that competes with free histamine for binding at HA-receptor sites. This antagonizes the effects of histamine on HA-receptors, leading to a reduction of the negative symptoms brought on by histamine HA-receptor binding. The product label for carbinoxamine as an over the counter cough and cold medicine is being modified to state "do not use" in children under 4 years of age in order to prevent and reduce misuse, as many unapproved carbinoxamine-containing preparations contained inappropriate labeling, which promoted unapproved uses (including management of congestion, cough, the common cold, and the use in children under 2 years of age), which can potentially cause serious health risks.
DB00434CyproheptadineA serotonin antagonist and a histamine H1 blocker used as antipruritic, appetite stimulant, antiallergic, and for the post-gastrectomy dumping syndrome, etc. [PubChem]
DB01075DiphenhydramineDiphenhydramine, also known commercially as Benadryl, is a first generation antihistamine that is used primarily for the treatment of seasonal allergies. However, it also has antiemetic, antitussive, hypnotic, and antiparkinson properties. As histamine receptors exist both peripherally and in the central nervous system, diphenhydramine has been shown to cause sedation due to its competitive antagonism of histamine H1 receptors within the central nervous system. While its use in in allergies has largely fallen out of favour due to this sedative effect, diphenhydramine has been repurposed for use within many OTC (over the counter) cough-and-cold medications that have been marketed for "night time" use. Diphenhydramine is also used in combination with [DB14132] as the anti-nausea drug [DB00985] where it is utilized primarily for its antagonism of H1 histamine receptors within the vestibular system [A1540]. Diphenhydramine has also been shown to be implicated in a number of neurotransmitter systems that affect behaviour including dopamine, norepinephrine, serotonin, acetylcholine, and opioid [A1539]. As a result, diphenhydramine is being investigated for its anxiolytic and anti-depressant properties.
DB00668EpinephrineEpinephrine injection is used for emergency treatment of severe allergic reactions (including anaphylaxis) to insect bites or stings, medicines, foods, or other substances. It can also be used in the treatment of idiopathic anaphylaxis (unknown cause) or exercise-induced anaphylaxis. When given intramuscularly or subcutaneously it has a rapid onset and short duration of action [FDA label]. In addition to the above function, epinephrine is the primary drug administered during cardiopulmonary resuscitation (CPR) to reverse cardiac arrest [A37697], [A37699]. This drug has been available since 1987 in the USA, however many new products have been approved under various names over the last several decades [L4355], [L4356], [L4358]. On August 16, 2018, Teva Pharmaceuticals USA gained approval to market its generic epinephrine auto-injector in 0.3 mg and 0.15 mg strengths [L4353].
