Diphenhydramine Action
Blocks H1 and H2 receptors which block histamine release in the respiratory tract, blood vessels, and GI tract
Diphenhydramine is a medication that is used to treat allergies, hay fever, and certain types of motion sickness. It belongs to a class of drugs called antihistamines, which work by blocking the effects of histamine, a natural chemical that is responsible for triggering allergy symptoms.
When histamine is released in the body, it binds to histamine receptors, causing the blood vessels to dilate, which results in symptoms such as itching, redness, swelling, and runny nose. This is where Diphenhydramine comes in – it blocks the histamine receptors, preventing the release of histamine and reducing the symptoms of allergies and motion sickness.
Diphenhydramine also has sedative properties, which can help with insomnia or sleep disturbances that may occur as a result of allergies or illness.
In summary, Diphenhydramine acts as an antihistamine and sedative, treating allergic reactions and motion sickness, as well as aiding in sleep.
