Final answer:
Pruritus can be neuropathic or inflammatory. Moisturizing creams contain substances that provide hydration, form a barrier, soothe irritation, and promote skin repair to alleviate itching and inflammation.
Step-by-step explanation:
Pruritus, also known as itching, can be classified as neuropathic or inflammatory. Neuropathic pruritus refers to itching that arises from damage to the peripheral or central nervous system. Some common pharmacological mediators of itching include histamine, prostaglandins, leukotrienes, and neuropeptides.
A moisturizing cream typically contains substances such as emollients, humectants, occlusives, and soothing agents. These substances help alleviate itching and inflammation of the skin by providing hydration, forming a barrier to prevent moisture loss, soothing irritation, and promoting skin repair.
Examples of substances found in moisturizing creams include glycerin, hyaluronic acid, ceramides, shea butter, and aloe vera. These substances have properties such as moisturizing, calming, anti-inflammatory, and wound-healing effects, which can help alleviate itching and inflammation of the skin.
