Pharmacology of MOS Flashcards
What are the doses of low, medium and high dose Glucocorticoids
Low: 5-10 mg/d
Medium: 20-40 mg/d
High: 60 mg/d
MOA for Glucocorticoids
Regulation of transcription of certain genes; suppress macrophage activation, WBC trafficking and cytokine production
Side Effects of Glucocorticoids
Insomnia/Psychosis/Irritability Weight gain Hyperglycemia Cushing's Syndrome HTN Infection Osteoporosis Cataracts
What MUST you consider before placing a patient on Glucocorticoids
PPD testing
Review/Update immunizations
Calcium/Vitamin D supplementation
Antimalarial agent that can also be used as an anti-inflammatory; Inhibits TLR signaling, and thus cytokine production and WBC activity; used for SLE, RA and Sjogren syndrome; CONTRAINDICATED with retinopathy and G6PD deficiency
Hydroxychloroquine
Indications for Hydroxychloroquine
Malaria prophylaxis
SLE
RA
Sjogren Syndrome
Contraindications for Hydroxychloroquine
G6PD deficiency
Retinopathy
How does Hydroxychloroquine have anti-inflammatory effects?
Inhibit TLR signaling–> dec. cytokines and WBC activity
Dihydrofolate Reductase inhibitor used for inflammatory and autoimmune diseases; CONTRAINDICATED in Pregnancy or with Sulfamethoxazole
Methotrexate
MOA of Methotrexate
Dihydrofolate Reductase inhibitor -> interferes with DNA synthesis
Contraindications for Methotrexate
PREGNANCY
Sulfamethoxazole
____________ ___________ is administered prophylactically along with Methotrexate to prevent megaloblastic anemia and glossitis
Folic Acid
Side Effects of Methotrexate
Fatigue/Nausea Mucosal ulcerations Hepatotoxicity Bone Marrow toxicity Pneumonitis
*note that most involve rapidly dividing cells
Dihydroorate Dehydrogenase Inhibitor (no Orotate–> no de novo pyrimidine synthesis); used for arthritis and SLE; TERATOGEN
Leflunomide
MOA of Leflunomide
Dihydroorate Dehydrogenase inhibitor (no Orotate–> no de novo pyrimidine synthesis)
Side Effects of Leflunomide
Rash Alopecia Diarrhea Liver toxicity Bone marrow toxicity
*note most have rapidly dividing cells
