What are steroids?

  • Steroids (or "glucocorticoids") are a class of hormones that are naturally produced in the body’s adrenal glands and can also be made synthetically for medical use.

  • In medicine, they are often prescribed to reduce inflammation or suppress an over‑active immune response.


How do steroids work?

  1. Binding to receptors – Steroids enter cells and bind to specific glucocorticoid receptors in the cytoplasm.

  2. Gene regulation – The steroid–receptor complex moves into the nucleus, where it can turn on or off certain genes that control inflammation.

  3. Reducing inflammatory mediators – By altering gene expression, steroids decrease the production of pro‑inflammatory chemicals (like cytokines and prostaglandins) and increase anti‑inflammatory ones.

  4. Suppressing immune cells – They also inhibit the activity of various immune cells (e.g., T‑cells, macrophages), further dampening inflammation.


Because this action is powerful but not entirely specific, steroids can produce side effects such as weight gain, osteoporosis, mood changes, and increased infection risk.




3. Other Common Anti‑Inflammatory Medications









Drug ClassTypical DrugsMechanism of Action (Simplified)Common Uses
Non‑steroidal anti‑inflammatory drugs (NSAIDs)Ibuprofen, Naproxen, DiclofenacInhibit cyclooxygenase enzymes (COX‑1 & COX‑2), reducing prostaglandin production.Pain relief, fever reduction, mild to moderate inflammation
Selective COX‑2 inhibitorsCelecoxibPreferentially blocks COX‑2 enzyme, aiming to reduce pain/inflammation while sparing COX‑1 (gastric protection).Osteoarthritis, rheumatoid arthritis
Corticosteroids (synthetic)Prednisone, MethylprednisoloneMimic cortisol’s effects: inhibit phospholipase A2 → ↓ arachidonic acid → ↓ inflammatory mediators; also suppress immune cell activation.Severe inflammation, autoimmune diseases
Non‑steroidal immunosuppressantsMethotrexate (low dose)Inhibits dihydrofolate reductase → ↓ DNA synthesis in rapidly dividing cells; at low doses it increases adenosine → anti‑inflammatory.Rheumatoid arthritis, psoriasis
Biologic agentsTumor necrosis factor inhibitors (adalimumab, infliximab), interleukin‑6 receptor blockers (tocilizumab)Neutralize cytokines or block their receptors → reduce downstream inflammatory signaling.Autoimmune diseases

3. Mechanistic Summary of How These Agents Reduce Inflammation








Step in Inflammatory CascadeTarget of DrugResulting Effect
T‑cell activation & cytokine releaseImmunomodulators (cyclosporin, tacrolimus, mycophenolate)↓ T‑cell proliferation → ↓ IL‑2, IFN‑γ, TNF‑α
Macrophage/monocyte activationAnti‑TNF antibodies (adalimumab)Block TNF‑α binding to receptors → ↓ NF‑κB signaling
Pro‑inflammatory cytokine amplification loopCytokine inhibitors (tocilizumab, anakinra)Inhibit IL‑6 or IL‑1 pathways → ↓ downstream acute‑phase response
Complement activation & endothelial damageC5a inhibitor (avacopan)Prevent complement cascade → ↓ leukocyte recruitment

Key Take‑aways



  • Biologics are complex and require sophisticated manufacturing, stringent controls, and long‑term stability data.

  • Regulatory pathways for biologic drugs emphasize rigorous preclinical and clinical evidence due to their higher risk profile.

  • The approval process is a multi‑stage journey, often spanning 10–15 years from discovery to market entry, especially when the product involves novel mechanisms or genetic manipulation.

  • Strategic planning early in development (e.g., community.srhtech.net selecting the right expression system, establishing robust QC methods, and aligning with regulatory guidance) can dramatically reduce time‑to‑market.


This framework equips you with a high‑level view of the entire biologic drug approval landscape—critical knowledge for navigating your own projects or advising stakeholders in biotech ventures.
