Unpacking the Terminology: What is another name for topical cream?
A topical medication is any medicine that is applied directly to a specific area of the body, most often the skin, to treat ailments [1.3.5]. While 'cream' is a common term, it's part of a larger family of preparations. Another name for topical cream could be ointment, lotion, gel, paste, or emollient, depending on its specific formulation and consistency [1.2.2, 1.3.1].
These terms are not just synonyms; they describe different types of topical preparations with distinct properties determined by their ratio of oil and water [1.4.5]. An emollient, for instance, is a broader term for a preparation that softens and soothes the skin, which can come in the form of a cream, lotion, or ointment [1.2.1]. Other related terms include unguent, salve, balm, and liniment [1.2.2, 1.2.3].
How Topical Medications Work
The skin serves as a protective barrier, but topical medications are designed to penetrate this barrier to deliver active ingredients to a localized area or even into the bloodstream for systemic effects [1.7.4, 1.7.5]. The primary mechanism is diffusion, where the drug moves from a high concentration (the cream) to a lower concentration (the skin) [1.7.4].
The effectiveness of this process depends on several factors:
- The Drug Itself: The molecular size and properties of the active ingredient play a crucial role [1.7.4].
- The Vehicle: The base of the medication (cream, ointment, etc.) affects how the drug is released and absorbed [1.7.5]. For example, occlusive ointments form a barrier that traps moisture and can enhance penetration [1.4.2].
- Skin Condition: The integrity of the skin is a major factor. Absorption is increased in skin that is compromised by conditions like eczema, psoriasis, or burns [1.7.5].
- Application: The location on the body and whether an occlusive dressing is used can alter absorption rates [1.9.5].
Creams, Ointments, Gels, and Lotions: A Comparison
The primary difference between these topical forms lies in their oil-to-water ratio, which dictates their consistency, feel, and ideal use cases [1.4.5].
- Ointments: These are typically about 80% oil and 20% water. They are greasy, thick, and create a barrier on the skin that locks in moisture, making them ideal for very dry skin conditions like psoriasis or for protecting wounds [1.4.2, 1.5.5]. Because they stay on the skin longer, they allow for maximum absorption of medication [1.4.2].
- Creams: Creams are emulsions with a more balanced ratio, often around 50% oil and 50% water [1.4.5]. They are thicker than lotions but less greasy than ointments. This balanced formulation makes them suitable for treating dry skin, rashes, and weeping skin lesions, as they are moisturizing but also allow the skin to breathe [1.3.3, 1.4.2].
- Lotions: Lotions contain more water than oil, giving them a much thinner, non-greasy consistency [1.4.2]. They spread easily over large areas and are quickly absorbed, making them a good choice for normal or oily skin and for application on hairy areas [1.4.3, 1.5.2].
- Gels: Gels are typically oil-free and have a high water content, often with alcohol or cellulose as a base [1.3.5, 1.4.2]. They are lightweight, non-greasy, and liquefy on contact with the skin, leaving a thin film of the active ingredient. Gels are well-suited for oily skin and hairy areas like the scalp [1.3.5, 1.4.3].
- Pastes: Pastes are thick preparations that combine oil, water, and a high proportion of powder (20-50%) [1.3.6]. This makes them very stiff and able to form a protective layer, such as zinc paste used for diaper rash [1.5.3].
| Preparation | Oil/Water Ratio | Consistency | Best For |
|---|---|---|---|
| Ointment | ~80% Oil, 20% Water [1.4.5] | Thick, greasy, occlusive [1.4.2] | Very dry, scaly skin (e.g., psoriasis); maximum medication absorption [1.4.2, 1.5.5] |
| Cream | ~50% Oil, 50% Water [1.4.5] | Smooth, less greasy than ointment [1.4.2] | Dry skin, rashes, weeping lesions [1.3.3, 1.4.2] |
| Lotion | High Water, Low Oil [1.4.2] | Thin, non-greasy, runny [1.4.3, 1.4.5] | Normal to oily skin; large body areas; hairy areas [1.4.3, 1.5.2] |
| Gel | Water-based, oil-free [1.3.5] | Lightweight, transparent, self-drying [1.4.4, 1.4.6] | Oily skin; hairy areas (e.g., scalp) [1.3.5] |
Common Applications and Active Ingredients
Topical preparations are used to treat a vast number of conditions. Some of the most common applications include:
- Inflammatory Skin Conditions: Steroids like hydrocortisone are used for eczema, dermatitis, and psoriasis to reduce inflammation and itching [1.5.1, 1.5.6].
- Infections: Antibacterial ingredients (e.g., Neosporin) and antifungal agents (e.g., miconazole) treat skin infections [1.5.2, 1.5.5].
- Acne: Ingredients like benzoyl peroxide, salicylic acid, and retinoids are used to treat acne [1.8.3].
- Pain Relief: Topical analgesics can provide targeted relief for localized pain [1.7.4].
- Moisturizing and Protection: Emollients and barrier creams containing ingredients like petrolatum or dimethicone protect the skin and prevent water loss [1.2.4, 1.8.3].
Risks and Considerations
While generally safe, topical medications can have side effects. Local reactions are most common and can include skin irritation, burning, stinging, thinning of the skin (atrophy), or changes in pigmentation [1.9.1, 1.9.3].
Systemic side effects can occur if a potent medication is used over a large area for a long time, as the drug can be absorbed into the bloodstream. This is a greater risk for children due to their higher surface area to body weight ratio [1.9.3, 1.9.5]. It is important to use these medications as directed by a healthcare professional and to report any unusual symptoms [1.9.1].
Conclusion
While many use 'cream' as a catch-all term, the world of topical medications is diverse. Another name for topical cream could be ointment, lotion, gel, or emollient, each with a unique composition designed for specific purposes. The choice between them depends on the skin condition being treated, the area of application, and the desired effect, from deep moisturization with a greasy ointment to lightweight hydration from an oil-free gel. Understanding these differences allows for more effective and targeted treatment of a wide array of dermatological issues.
