Urticaria rash symptoms urticaria hives allergies

Type I hypersensitivity (or immediate hypersensitivity) is an allergic reaction provoked by reexposure to a specific type of antigen referred to as an allergen. Type I is not to be confused with Type II, Type III, or Type IV hypersensitivities.

Exposure may be by ingestion, inhalation, injection, or direct contact.

Urticaria Rash

Cholinergic urticaria (CU) is one of the physical urticaria (commonly referred to as hives), which is provoked during sweating events.

CU was first described by Duke in 1924. The term cholinergic is derived from the finding that hives similar to those of CU can be evoked using cholinergic agonists (e.g. methacholine).

Allergy

Cold Urticaria (essentially meaning "cold hives") is an allergy where hives (urticaria) or large red welts form on the skin after exposure to a cold stimulus. The welts are usually itchy and often the hands and feet will become itchy and swollen as well. Hives vary in size from about 7mm in diameter to as big as about 27mm diameter or larger. The disease is classified as chronic when hives appear for longer than 6 weeks; they can last for life, though their course is often unpredictable. This disorder, or perhaps two disorders with the same clinical manifestations, can be inherited (familial cold urticaria) or acquired (primary acquired cold urticaria). The acquired form is most likely to occur between ages 18–25.

Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
