Pharma 46: Adrenal Corticosteroids - Stress, Survival, Restraint

This episode explores adrenal corticosteroids as the pharmacology of adaptive stress. Glucocorticoids and mineralocorticoids are essential for survival-mobilising energy, maintaining blood pressure, and modulating immunity-but their power lies in transience. We trace ACTH control, steroid synthesis, receptor actions, and feedback suppression to understand why both deficiency and excess produce characteristic, system-wide syndromes. Therapeutically, this is a chapter about respect: dosing, timing, and tapering matter as much as the drug itself.Key takeaways to carry forward:* Axis control: ACTH as a gatekeeper rather than a throttle.* Steroid diversity: glucocorticoid vs mineralocorticoid effects and targets.* Genomic influence: why effects are delayed yet enduring.* Clinical use and misuse: replacement, anti-inflammatory therapy, and iatrogenic harm.* Withdrawal logic: adrenal suppression and the necessity of tapering.
