Triamcinolone

Also known as Kenalog · Aristocort · Triamcinolone acetonide · Nasacort

Triamcinolone is a synthetic intermediate-to-long-acting glucocorticoid, roughly five times as potent as cortisol, used heavily as a depot intra-articular and intramuscular injection (triamcinolone acetonide) and in topical/inhaled forms. In sport and recovery it is one of the most common joint-injection corticosteroids — effective for localised inflammation but chondrotoxic on repeat use and systemically suppressive from depot absorption.

01 Overview

Triamcinolone acetonide forms a long-lasting depot, giving weeks of local anti-inflammatory effect after a single joint or soft-tissue injection. This makes it popular for tendinopathy, bursitis and arthritis flares. Topical triamcinolone is a mainstay for inflammatory skin disease and the acetonide is also used in dental pastes and nasal sprays.

Despite being 'local', depot triamcinolone is absorbed systemically enough to suppress the HPA axis for weeks and to raise blood glucose transiently. Repeated intra-articular injections carry the same cartilage-harm concern as other corticosteroids. WADA prohibits injectable triamcinolone in-competition.

02 Mechanism

Glucocorticoid receptor agonist; the acetonide ester forms a poorly soluble depot for prolonged local anti-inflammatory action.
