What is the primary use of a cream in medication?

The primary use of a cream in medication is for skin protection. Creams are semi-solid emulsions that are typically applied topically to the skin. They serve various purposes such as moisturizing the skin, providing a barrier against irritants, and delivering medication directly to a localized area. This topical application allows for the direct treatment of skin conditions, such as rashes, dermatitis, or infections, while simultaneously protecting the skin from external factors.

In contrast to other forms of medication, creams are particularly effective for conditions requiring localized treatment without the need for systemic absorption. This allows for higher concentrations of a drug at the site of application, which can enhance its therapeutic effects while minimizing systemic side effects.
