Question

Which among the following drugs reduces the symptoms of allergy?

• A. Anti-histamine
• B. Steroids
• C. Adrenaline
• D. All of these

Answer 1

The correct option is D All of these

The exaggerated immune response of the immune system to certain foreign substances is called allergy. These substances are called allergens as they induce allergy. Dust mites, pollen, spores etc. are the common allergens.

There are various reasons for allergies. Allergies tend to run in families, suggesting that they have a genetic basis.

Symptoms of allergic reactions include sneezing, watery eyes, running nose and difficulty in breathing, sore throat, itching, rashes etc.

There is release of histamines and serotonin from the mast cells which causes the symptoms of allergy.

Administering drugs like antihistamine, adrenaline and steroids quickly reduces the symptoms of allergy.

Antihistamines are medicines that work against or block histamine.

Steroid preparations are known to have anti-inflammatory and immunosuppressive properties and are widely used in the treatment of allergies.

It is observed that epinephrine/adrenaline binds to specific receptors on the immune cells which helps to suppress further release of histamine.
