What is commonly used to dilute hydrocortisone ointment?

• A. Water
• B. Petroleum jelly
• C. Olive oil
• D. Alcohol

Answer: (B)

Dilution of hydrocortisone ointment is typically accomplished using a substance that can effectively mix with the ointment and maintain its medicinal properties while enhancing application. Petroleum jelly is frequently chosen for this purpose because it shares similar characteristics and can create a smooth texture, facilitating better spreadability on the skin. This is particularly important for topical medications, as it enhances patient compliance and ensures the effective delivery of the active ingredient. On the other hand, options like water and alcohol would not be suitable for diluting hydrocortisone ointment because they can disrupt the oil-based emulsion, potentially leading to a loss of effectiveness and changes in texture. Olive oil, while it might be suitable for some formulations, is not the standard practice for hydrocortisone ointment dilution due to its different consistency and potential to alter the ointment’s properties. Therefore, petroleum jelly is the preferred choice for its compatibility and beneficial characteristics when diluting hydrocortisone ointment.
