Answer 1

The second most common drug eruption after exanthematous drug eruptions is known as urticaria. It is characterized by the development of wheals, which are raised, itchy welts on the skin that typically last for a few hours.

Step-by-step explanation:

The subject of this question is Medicine.

This condition is known as urticaria which is a type of skin eruption.

It is characterized by the development of wheals, which are raised, itchy welts on the skin that typically last for a few hours.

These wheals occur due to the leakage of plasma from small blood vessels into the surrounding connective tissue of the dermis.

For example, allergists use skin testing to identify allergens in type I hypersensitivity reactions.

In skin testing, allergen extracts are injected into the epidermis, and a positive result of a soft, pale swelling at the site surrounded by a red zone (called the wheal and flare response) occurs.
