Study Notes
Hormones and Steroids
- Aldosterone influences hypertension, hypokalemia, and edema through mineralocorticoid receptor stimulation.
- Glucocorticoids alter glucocorticoid response elements (GRE) affecting cytokine transcription via RNA polymerase II.
- Long-term steroid use can lead to adrenal suppression.
Proliferation Signal Inhibitors
- Sirolimus and everolimus are mTOR inhibitors used in immune modulation.
- mTOR is crucial for cellular signaling, affecting various cellular responses.
- Notable side effects include weight gain, hyperglycemia, and potentially diabetes mellitus.
Cyclophosphamide
- An alkylating agent that destroys proliferating lymphoid cells and alters some resting cells.
- Common adverse effects include hypertension and altered mental status.
Monoclonal Antibodies for Autoimmune Therapy
- Agents like Abciximab prevent ischemic complications in at-risk patients.
- Adalimumab, Certolizumab, Golimumab, and Infliximab target soluble TNF-alpha for conditions like rheumatoid arthritis and IBD.
H1 Receptor Antagonists
- Various types exist, including dibenzozaxepine and phenothiazine, each with specific actions and uses.
- Frequent side effects include sedation, dizziness, and blurred vision.
Adverse Effects of H1 Receptor Antagonists
- Notable effects include euphoria, tinnitus, and tremors, with some causing prolonged QT intervals leading to arrhythmias.
- These adverse effects may be exacerbated by certain antibiotics and antifungals that inhibit drug metabolism.
Specific Medications
- Doxepin acts on both H1 and H2 receptors, utilized for depression, while Promethazine serves as a first-generation H1 antagonist with sedative effects.
- Preferred in younger patients for conditions like motion sickness.
