Antihistamine: Mechanism of action and classes Antihistamines are antagonist or inverse agonist of histamine receptors(HRs) which can help manage the symptoms associated with allergies. This research report aims to explore the mechanism of action and the classes of antihistamines. The report also attempts to answer the hypothesis that increased antihistamine levels will affect the immune function and the allergic response. Antihistamines counteract the action of histamines by binding to HRs…

Pet Allergy Overview Over 60% of households owns some type of pet with a large majority of those animals being cats and dogs. Sadly, millions of those pet owners have pet allergies. Pet allergies are typically referred to as allergic rhinitis. You are not allergic to your actual pet but to the protein that is found in their saliva, urine, dead skin, and dander. This protein aggravates asthma sufferers and causes allergic reactions in others. Are There Hypoallergenic Pets? Many allergy…

the pretty flowers and baby bunnies, comes the dreaded seasonal allergies. For myself, this means rubbing my eyes until it looks like I’ve just watched a heartbreaking romantic comedy, sneezing so powerfully that it physically hurts, and itching my nose and giving myself a lovely (insert sarcasm here) horizontal crease. Allergies drive me crazy, but at the same time, I’m amazed at how it works and the reason behind having allergies. When a foreign substance, such as flower pollen in the case…

these symptoms were due to the increase of allergen presence the school environment contained. Allergens are one of the main factors that increase the occurrence of an asthmatic episode; allergens include peers with pets, mold, perfumes, smoke, and food all of which are greater risks in highly populated areas (Hsu et. al, 2016). Other factors including poor air quality in the school, poorly cleaned school environment, and stress also increase…

While these symptoms are similar to those of allergic rhinitis (hay fever), non-allergic rhinitis does not involve the immune system which overacts to allergens (American Academy of Allergy, Asthma & Immunology, 2016). Non-allergic rhinitis also rarely causes itchy nose, eyes or throat which would not explain John’s itchy eyes. Although this condition is similar to AR and provides explanation to some of John’s symptoms, it fails to…

Pharmacodynamics Pharmacodynamics refers to the mechanisms of drug action. Loratadine is a “non-sedating” tricyclic anti-histamine that possesses competitive, selective, peripheral H1-receptor antagonistic activity. The onset of the anti-histaminic effect occurs 1-2 hours after the administration of the drug and the peak effect occurs between 8-12 hours. Loratadine is known as a long-acting anti-histamine as its anti-histaminic effect can persist for up to 24 hours. Histamine is produced from…
