Topical Therapy for Pruritus

Chapter 95

Topical Therapy for Pruritus

The use of topical therapeutics for pruritus in the form of shampoos, lotions, rinses, soaks, and spot-on products has gained increasing popularity. Topical treatment for pruritus can be used as sole therapy or as an adjunctive therapy, reducing the need for systemic treatment. Owner compliance can be a problem, although many owners want to participate actively in the management of their pet’s skin condition.

Familiarity with available products is important, and personal use of products on one’s own pets provides experience and insight, and constitutes a powerful recommendation to your clients. The frequency of application is patient and disease dependent; typically, applications as often as once daily are required. Contact time may be important for the best efficacy, and it is critical to know which products can be left on and which require complete rinsing to avoid irritation.

Specific Antipruritic Agents

Protectants and Moisturizing Agents

Protectants and moisturizing agents include oils and hygroscopic agents (vegetable oils, lanolin, phytosphingosine, propylene glycol, glycerin, colloidal oatmeal, urea, and lactic acid). Moisturizers increase the water content of the stratum corneum, are useful in hydrating and softening the skin, and work best if applied immediately after saturation of the stratum corneum with water. Formulations such as sprays and rinses that are left on are generally more effective than shampoos that are washed off (Table 95-1).
