Final answer:
Creams and ointments are both types of topical medications used to moisturize and lubricate the skin. Creams can be oil-in-water or water-in-oil, with different properties. Ointments, on the other hand, are generally more potent and provide a stronger lubricating effect.
Step-by-step explanation:
Creams and ointments are both types of topical medications that can be used to moisturize and lubricate the skin. However, the potency and lubricating properties of each can vary.
Creams are semi-solid emulsions of oil and water. They can be oil-in-water (O/W) creams or water-in-oil (W/O) creams. O/W creams are less greasy and more easily washed off with water, while W/O creams provide a more moisturizing effect.
Ointments are a type of semi-solid dosage form, usually made with petrolatum. They are generally more potent and provide a stronger lubricating effect compared to creams.
