Pharmacology

đŸ”Ŧ

Mechanism of Action

Triamcinolone is a synthetic glucocorticoid. It exerts its anti-inflammatory and immunosuppressive effects by binding to intracellular glucocorticoid receptors. This complex then translocates to the nucleus, where it modulates gene expression, leading to the synthesis of anti-inflammatory proteins (e.g., lipocortin) and inhibition of pro-inflammatory mediators (e.g., prostaglandins, leukotrienes, cytokines like IL-1, IL-6, TNF-alpha). It also suppresses the migration of polymorphonuclear leukocytes and reverses increased capillary permeability.

Special Patient Groups

🤰

Pregnancy

Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Animal studies show teratogenicity. Human data are limited but suggest a possible association with cleft palate and intrauterine growth restriction.

Trimester-Specific Risks:

First Trimester: Possible increased risk of cleft palate (based on animal data and some human studies, though not definitively proven).
Second Trimester: Risk of intrauterine growth restriction.
Third Trimester: Risk of adrenal suppression in the neonate if used systemically in high doses, requiring monitoring.
🤱

Lactation

Triamcinolone is excreted in breast milk. While the amount is generally small, caution is advised. Monitor the infant for signs of adrenal suppression (e.g., poor weight gain) or other adverse effects.

Infant Risk: L3 (Moderate risk - compatible with caution. Monitor infant for adverse effects, especially with high doses or long-term use.)
đŸ‘ļ

Pediatric Use

Corticosteroids can suppress growth in children. Long-term use should be carefully monitored. Adrenal suppression can occur. Dosing must be individualized and the lowest effective dose used for the shortest possible duration.

👴

Geriatric Use

Elderly patients may be more susceptible to adverse effects, particularly osteoporosis, fluid retention, hypertension, and diabetes. Use the lowest effective dose and monitor closely.
