Vehicles for Drug Delivery and Cosmetic Moisturizers: Review and Comparison

Area of Science:

• Dermatology
• Pharmaceutics
• Cosmetics

Background:

• Topical therapeutic products are essential for dermatological conditions like eczema and psoriasis.
• Topical vehicles facilitate drug delivery across the stratum corneum (SC) into the epidermis and dermis, minimizing systemic absorption.
• These vehicles also function as cosmetic moisturizers (emollient therapy) for dry skin, crucial in managing xerosis, eczema, psoriasis, and aging.

Purpose of the Study:

• To review common topical vehicles used for both drug delivery and cosmetic moisturization.
• To examine the formulation, advantages, disadvantages, and skin effects of various topical vehicles.
• To briefly discuss global regulatory rules concerning topical product claims.

Main Methods:

• Literature review of common topical vehicles (ointments, creams, gels, lotions).
• Analysis of vehicle properties, formulation, and impact on drug delivery and skin.
• Examination of regulatory considerations for topical product claims.

Main Results:

• Topical vehicles are critical for effective drug delivery and skin hydration.
• Vehicle choice significantly impacts product potency, efficacy, and patient compliance.
• Different vehicles (ointments, creams, gels, lotions) offer distinct advantages and disadvantages.

Conclusions:

• Optimal selection of topical vehicles based on skin characteristics is vital for therapeutic and cosmetic outcomes.
• Understanding vehicle formulation and properties enhances treatment efficacy and patient adherence.
• Regulatory compliance is a key consideration for topical product claims worldwide.
