describe the purpose of these types of drugs.

2. (lo 9 - 3) keratolytics
3. (lo 9 - 3) protectives

Explanation:

• Pruritus: It is the medical term for itching. It can be a symptom of various skin conditions, allergic reactions, or internal diseases.
• Erythema: Refers to redness of the skin. This occurs due to increased blood flow in the capillaries of the skin. It can be caused by inflammation, injury, or certain medical conditions.
• Edema: Swelling caused by excess fluid trapped in the body's tissues. It can occur in various parts of the body, such as the legs, ankles, or hands.
• Keratin: A fibrous structural protein. It is the key component of hair, nails, and the outer layer of human skin. It provides strength and protection.
• Inflammation: A biological response of the body's tissues to harmful stimuli. It is a protective attempt by the body to remove the injurious stimuli and initiate the healing process. Signs include redness, heat, swelling, pain, and loss of function.
• Acne: A common skin condition that occurs when hair follicles plug with oil and dead skin cells. It can cause whiteheads, blackheads, or pimples.
• Body temperature: The measure of the body's internal heat. The normal human body temperature is around 37°C (98.6°F), but it can vary slightly.
• Sebum: An oily secretion of the sebaceous glands. It lubricates the skin and hair. Overproduction of sebum can lead to acne.
• Antipruritics: Drugs used to relieve itching. They can work by numbing the skin, reducing inflammation, or blocking the histamine response (in case of allergic itching).
• Keratolytics: Agents that cause peeling or shedding of the horny layer (stratum corneum) of the skin. They are used to treat conditions like warts, corns, calluses, and certain skin disorders where there is excessive keratin build - up.
• Protectives: Drugs or substances that create a barrier on the skin. They protect the skin from further irritation, friction, or environmental factors. For example, they can be used in diaper rash creams to protect the baby's skin from urine and feces.
