MOA. Triamcinolone has anti-inflammatory, antipruritic, and vasoconstrictive properties. Corticosteroids are thought to act by the induction of phospholipase A2 inhibitory proteins, lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor, arachidonic acid. Arachidonic acid is released from membrane phospholipids by phospholipase A2.

Efficacy Monitoring Parameters. Improvement in clinical signs of skin disorder.
Toxicity Monitoring Parameters. Seek medical attention if severe skin irritation or symptoms worsen after administration.
Key Patient Counseling Points. Apply thin layer to affected area of skin. Skin should be clean and intact at site of application. Avoid contact with eyes and do not ingest by mouth. Avoid occlusive dressings or tight-fitting clothes over site of administration.
Clinical Pearls. Large number of dosage formulations (foams, gels, shampoos, etc), both by prescription and over-the-counter, are available. Oral and inhaled formulations, administered for systemic action, also available and used for similar indications as other oral and corticosteroids. Application to large surface areas, prolonged use, and occlusive dressings increase risk of systemic absorption and toxicity; pediatric patients are more susceptible to systemic absorption.
