DMARD1
methotrexate (rheumatrex, trexal)
considered folic acid antagonist
Methotrexate
can slow or stop progression of RA
oral or SQ once a week for RA
Considered first choice DMARD
high doses are used to treat some breast, skin, head/neck, and lymphoma or leukemia type cancers
Methotrexate
NI
• Relatively safe and low cost.
• Hepatotoxicity & Bone Marrow Suppression are the main side effects: assess liver function prior and during. BMS-need to know about symptoms of infection.
a. Cbc, lft, jaundice
b. Call if developing mouth sores (folic acid deficiency)
• Higher risk of cardiac event in anyone with RA
• AE: some studies show patients on this drug are more likely to develop melanoma and lymphoma
• AE: potential higher risk of GI ulceration w/ some DMARD I drugs:
a. GI bleed
b. Take with food
c. Enteric coated
given PO, SQ, or IM once weekly
DMARDII
etanercept (enbril), adalimumab (humira)
like a sponge for TNF
Etanercept (enbril)
NI
o like a sponge for TNF (Enbrel)
• AE: Infections and reactivated infections
a. If have had tB, Hepatitis, shingles, etc it could reactivate.
b. Should avoid live vaccine: varicella, MMR
• AE: severe allergies: such as SJS, toxic epidermal necrolysis (most extreme SJS) , and erythema multiforme
• AE: HF
a. SOB, Edema in legs, echo-baseline and throughout, affecting ejection fraction?
pancytopenia
SERMS (selective estrogen receptor modulators)
Raloxifene (Evista)
Prevention and tx of postmenopausal osteoP
Raloxifene
Causes hypocalcemia, need to be on supplements
High risk for : PE, DVT,
hot flashes
Pregnancy x
biphosphanates
alendronate (fosamax), -dronate
reverse lost bone and reduce future risk in higher risk patients
Alendronate (fosamax)
Ni
Causes hypocalcemia, need to be on a supplement
Esophagitis is number one side effect, to the point of ulceration and bleeding to death.
Must sit up for at least 30 mins after taking. *
Must take on empty stomach*
notify provider if you experience GI issues.
Calcitonin
Salmon calcitonin
calcitonin NI
- AE: nasal dryness and irritation: (given nasally) alternate nares between doses
- AE: Hypocalcemia: stopping breakdown, trying to push calcium back into the bone. (all osteoporosis med do this), encourage calcium intake.
- AE: may lose therapeutic use after several years d/t antibodies
- Given intranasally, SQ or IM
Ca supplements
give with vitamin d.
hypercalcemia not generally and issue
Kidney stones more prevalent: drink lots of water.
Cholinesterase inhibitors
Cholinergic agent:
Neostigmine (prostigmin)
Neostigmine therapeutic use
Myasthenia gravis (improves muscle strength and endurance)
used to reverse nondepolarizing neuromuscular blocking agents.
Neostigmine NI
toxic doses do the opposite to contraction and cause muscle weakness and respiratory paralysis within one hour of administration:
