Hi Everyone,
Last week I covered creams as a vehicle for administering medication to skin and mucous membranes. Creams are an oil and water emulsion that are formulated to stay on the skin longer than gels, but not as long as ointments. Most creams are now designed to be non-greasy and quick absorbing. So how do they differ from ointments?
Ointments are also oil and water emulsions, however, they have a higher oil content. The higher oil content creates a preparation that will adhere to the skin longer and thus provide longer medicinal contact for wounds/areas that may need increased healing time. The higher oil content may also create a "greasy" feeling when the preparation is applied as it doesn't absorb as quickly as creams. This feature of ointments can also create a protective barrier around the wound and the wound bed which may or may not need a dressing to prevent removal from rubbing against clothing or other contact agents. Ointments may not be suitable for skin areas that are usually left uncovered, such as face and hands, unless a dressing can be applied.
Stay tuned for next weeks Part 3: Gels.
Sincerely and To Your Health,
Deanna
