auranofin |
Ridaura |
3 mg bid or tid |
Major side-effect with
auranofin which is an oral form of gold is diarrhea, also additional
GI side-effects including nausea or vomiting.
May also have mouth sores and irritation. May develop a gold induced skin rash. May cause changes in renal function with protein in the urine |
Auranofin or oral gold
is not being utilized with any great frequency now. It did not prove to be all that effective in rheumatoid arthritis
and had a significant incidence of diarrhea. It also had the potential for similar side-effects
as injectable gold with kidney toxicity and rash |
|
aurothioglucose |
Solganal |
May be given IM 10 mg as
a test dose and then 25 to 50 mg weekly |
Mouth irritation, rash,
kidney side-effects especially with protein in the urine, changes in
the blood count with decreased red cells, white cells or platelets |
|
|
azathioprine |
Imuran |
50 mg bid or tid with food |
GI upset, liver function
abnormalities |
This is an immunosuppressive
drug and therefore would have to be withdrawn or held if any significant
infectious disease occurred |
|
cyclophosphamide |
Cytoxan |
50 mg once a day up to
tid with meals. This medication
may also be given intravenously usually on a monthly treatment schedule |
Blood in the urine with
bladder inflammation with the potential for the development of bladder
cancer, GI upset, loss of fertility with the cessation of menses in
females. Suppression of the
bone marrow with decreased hemoglobin, white count or platelets. Anemia might induce fatigue and weakness.
The decrease in the white blood count could predispose an individual
towards an increased incidence of infections, the decrease in platelets
could cause significant bruising and bleeding |
This is a very potent immunosuppressive
drug. Its use in rheumatoid
arthritis is limited to the rare case of severe vasculitis not controlled
with other measures. This medication
is useful in severe systemic lupus erythematosus particularly with significant
lupus nephritis. There is the
potential of developing malignancies secondarily with long-term use
of this medication. In SLE it
is mainly given initially on a monthly basis intravenously for severe
disease and then the patient may be converted to an oral form of treatment. The medication is obviously limited by its
potential side-effects and needs to be monitored closely |
|
cyclosporin |
Neoral Sandimmune |
100 to 400 mg daily in
divided dosages based on individual's body weight which is usually 2.5-5
mg/kg (1 kg equals 2.2 pounds) |
Hair growth, kidney dysfunction,
increase in the blood pressure, changes in the gums with actual enlargement
of the gums or inflammation of the gums |
Difficult medication to
use because it has to be monitored closely regarding any changes in
the serum creatinine. It has
been used, however, successfully to control rheumatoid arthritis either
alone or even in combination with methotrexate, but the patient needs
to be under extremely close supervision.
The dosage needs to be tapered back with any 25% increase in
the creatinine level above the baseline value.
Patients needs to be monitored regarding any liver toxicity as
well. This drug has been used for many years in prevention of rejection
of transplanted organs and has helped increase the number of successful
transplants. |
|
gold sodium thiomalate |
Myochrysine |
10 mg IM as a test dose,
then increasing up to 25 mg to 50 mg weekly |
Kidney function abnormalities
with protein in the urine, changes in the blood count, rash. |
Gold was the standard treatment
for many years in rheumatoid arthritis. This has been supplanted by the use of methotrexate. The major concerns with using gold are the
development of kidney disease and a drop in any of the important blood
cells including the red blood cells, white blood cells and platelets. |
|
hydroxychloroquine |
Plaquenil |
200 mg once daily or twice
daily |
GI upset, rash, visual
changes involving the macula portion of the eye |
This medication is effective
in approximately 50% of rheumatoid arthritis patients particularly those
with mild to moderate disease. The
side-effects in the eyes are rare in patients who are taking 400 mg
per day or less of this medication, but rheumatologists recommend that
patients be monitored by an ophthalmologist at baseline prior to starting
this medication and then every six months to make sure that no early
changes are occurring. It is
also an important medication in systemic lupus erythematosus particularly
when the patient is having joint symptoms, skin involvement or pleurisy. |
|
methotrexate |
Rheumatrex |
7.5 mg to 25 mg weekly
given orally or may be given by intramuscular injection up to 50 mg
weekly maximum |
GI upset, rash, hair loss,
liver function abnormalities, change in blood count, in rare cases pulmonary
toxicity |
Patients should not be
taking alcohol while on methotrexate.
It is imperative that they be monitored initially every two weeks
for the first two to three months and then monthly with CBC, creatinine
and liver profile to make sure there are no changes in any of these
important lab values. Methotrexate
now serves as the most often prescribed DMARD in rheumatoid arthritis. If patients fail to be completely controlled
with methotrexate, then it may be combined with Arava or Enbrel or Remicade.
It also may be used in conjunction with Plaquenil. |
|
leflunomide |
Arava |
10 to 20 mg daily in a
single dose (after 100 mg a day loading dose for three days) |
Hair loss, skin rash, diarrhea,
liver function changes |
The diarrhea, hair loss
and liver changes may dissipate or decrease with lowering of the Arava
dosage from 20 to 10 mg daily. Otherwise
if these side-effects continue, then this medication may have to be
stopped. In patients with methotrexate
toxicity who could not continue on that drug, then Arava is an excellent
alternative. It also may be
used in conjunction with methotrexate in those patients who have not
had a complete remission. Patients
need to be monitored regularly with a CBC, creatinine and liver profile
similar to the monitoring that goes on with methotrexate. In patients who wish to conceive a child after being on Arava,
it is important to use a resin called cholestyramine over eleven days
to try to remove a significant amount of this medication. Levels of Arava may be obtained in a laboratory
to determine if there are any significant amounts of medication remaining.
The cholestyramine may also be used in cases of any acute toxicity.
Female patients who are on Arava should use appropriate birth
control measures as there is a significant potential for fetal abnormalities
if patient gets pregnant while on Arava |
|
penicillamine |
Cuprimine Depen |
125 to 250 mg up to tid |
GI side-effects including
diarrhea, decrease in taste, nausea or vomiting, rash, kidney side-effects
including protein in the urine |
This medicine is not used
as much now as it was years ago mainly because of the development of
newer and more potent medications.
Also penicillamine has significant side-effects including the
development of kidney disease as well as potential changes in the blood
count |
|
sulfasalazine |
Azulfidine |
500 mg one or two tabs
bid or tid |
GI upset with diarrhea,
rash, liver function abnormalities, changes in the blood count |
Patients who are allergic
to sulfa drugs should not use this medication as it is a sulfa derivative.
It has been used more in Europe to treat rheumatoid arthritis
than in the United States, but is gaining acceptance in the U.S. as
well. It also has been used
a great deal in treating ankylosing spondylitis particularly in Europe |
