GENERIC NAME: prednisolone
BRAND NAMES: Prednisolone, Pediapred Oral Liquid Medrol
DRUG CLASS AND MECHANISM: Prednisolone is
a synthetic adrenal corticosteroid. Corticosteroids
are natural substances produced by the adrenal glands
located adjacent to the kidneys. Corticosteroids have
potent anti-inflammatory properties, and are used in
a wide variety of inflammatory conditions such as arthritis,
colitis, asthma, bronchitis, certain skin rashes, and
allergic or inflammatory conditions of the nose and
eyes. There are numerous preparations of corticosteroids
including oral tablets, capsules, liquids, topical creams
and gels, inhalers and eye drops, and injectable and
intravenous solutions. Prednisolone that is prescribed
in oral tablet and liquid forms is addressed in this
article.
Dosage requirements of corticosteroids vary
among individuals and the diseases being treated. In
general, the lowest possible effective dose is used.
Corticosteroids given in multiple doses throughout the
day are more effective, but also more toxic, than if
the same total dose is given once daily, or every other
day.

STORAGE: Store at room temperature, sealed

PRESCRIBED FOR: Prednisolone is used to
achieve prompt suppression of inflammation in many inflammatory
and allergic conditions. Examples of inflammatory conditions
include rheumatoid arthritis, systemic lupus, acute
gouty arthritis, psoriatic arthritis, ulcerative colitis,
and Crohn's disease. Severe allergic conditions that
fail conventional treatment may also respond to prednisolone.
Examples include bronchial asthma, allergic rhinitis,
drug-induced dermatitis, and contact and atopic dermatitis.
Chronic skin conditions treated with prednisolone include
dermatitis herpetiformis, pemphigus, severe psoriasis
and severe seborrheic dermatitis. Chronic allergic and
inflammatory conditions of the uvea, iris, conjunctiva
and optic nerves of the eyes are also treated with prednisolone.
Prednisolone is also used in the treatment
of blood cell cancers (leukemias), and lymph gland cancers
(lymphomas). Blood diseases involving destruction of
platelets by the body's own immune cells (idiopathic
thrombocytopenia purpura), and destruction of red blood
cells by immune cells (autoimmune hemolytic anemia)
can also be treated with prednisolone. Other miscellaneous
conditions treated with this medication includethyroiditis
and sarcoidosis. Finally, prednisolone is used as a
hormone replacement in patients whose adrenal glands
are unable to produce sufficient amounts of corticosteroids.
DOSING: Should be taken with food.
DRUG INTERACTIONS: Prolonged use of prednisolone
can depress the ability of body's adrenal glands to
produce corticosteroids. Abruptly stopping prednisolone
in these individuals can cause symptoms of corticosteroid
insufficiency, with accompanying nausea, vomiting and
even shock. Therefore, withdrawal of prednisolone is
usually accomplished by gradual tapering. Gradually
tapering prednisolone not only minimizes the symptoms
of corticosteroid insufficiency, it also reduces the
risk of an abrupt flare of the disease under treatment.
Prednisolone and other corticosteroids can
mask signs of infection and impair the body's natural
immune response to infection. Patients on corticosteroids
are more susceptible to infections, and can develop
more serious infections than healthy individuals. For
instance, chicken pox and measles viruses can produce
serious and even fatal illnesses in patients on high
doses of prednisolone. Live virus vaccines, such as
small pox vaccine, should be avoided in patients taking
high doses of prednisolone, since even vaccine viruses
may cause disease in these patients. Some infectious
organisms, such as tuberculosis (TB) and malaria, can
remain dormant in a patient for years. Prednisolone
and other corticosteroids can reactivate dormant infections
in these patients and cause serious illnesses. Patients
with dormant TB may require anti-TB medications while
undergoing prolonged corticosteroid treatment.
By interfering with the patient's immune
response, prednisolone can impede the effectiveness
of vaccinations. Prednisolone can also interfere with
the tuberculin skin test and cause false negative results
in patients with tuberculosis infection.
Prednisolone impairs calcium absorption
and new bone formation. Patients on prolonged treatment
with prednisolone and other corticosteroids can develop
osteoporosis and an increased risk of bone fractures.
Supplemental calcium and vitamin D are encouraged to
slow this process of bone thinning. In rare individuals,
destruction of large joints can occur while undergoing
treatment with prednisolone or other corticosteroids.
These patients experience severe pain in the involved
joints, and can require joints replacements. The reason
behind such destruction is not clear.
