Other medications approved for relapsing
multiple sclerosis
Glatiramer acetate (Copaxone)
Glatiramer acetate (Copaxone) is another
DMD that is approved for reducing the frequency of relapses in RR-MS. Glatiramer acetate is a synthetic (man-made) amino acid mixture that may resemble a protein component of myelin. It is thought that the immune system reaction against myelin in
multiple sclerosis may be blocked or diminished by glatiramer acetate. A reaction occurring immediately after the injection of glatiramer acetate is common, affecting
one out of 10 patients. The reaction may involve flushing,
chest pain or tightness,
palpitations, anxiety,
shortness of breath, tightness in the throat, or hives. The reaction usually resolves within 30 minutes and requires no treatment. Some patients may be at risk of developing lipoatrophy, inflammation and destruction of
fat tissue beneath the skin at the site of injection.
Natalizumab (Tysabri®)
Natalizumab (Tysabri®) is a drug approved by the FDA to treat
relapsing multiple sclerosis. Natalizumab is a monoclonal antibody against VLA-4, a molecule required for immune cells to adhere to other cells,
and penetrate into the brain. It is administered via monthly intravenous infusions. It carries a warning for a potentially fatal disease, progressive multifocal leukoencephalopathy (PML), a viral infection of the brain that usually leads to death or severe disability. For this reason only patients who have signed up for treatment under a controlled drug distribution program can
receive treatment with natalizumab.
Natalizumab is used alone for the treatment of patients with relapsing forms of
multiple sclerosis to delay the progression of physical disability and reduce the frequency of clinical relapses. The safety and efficacy of natalizumab beyond two years are unknown.
The risk of PML may increase with prolonged exposure to natalizumab. Because natalizumab increases the risk of PML, it is generally recommended only for patients who have had an inadequate response to, or are unable to tolerate
an alternate
multiple sclerosis therapy.
Mitoxantrone (Novantrone®)
Mitoxantrone (Novantrone®) is approved by the FDA for the treatment of
multiple sclerosis (SP-MS, PR-MS, and worsening RR-MS). Mitoxantrone is a
chemotherapy drug that carries the risk of serious cardiac side effects or cancer
(leukemia). Because of these serious side effects, physicians tend to reserve its use for more advanced or worsening cases of multiple sclerosis, and there is a limit to the total amount of mitoxantrone that can be administered. Cardiac monitoring prior to each dose and yearly following the last dose of mitoxantrone also is necessary.
Mitoxantrone is used for reducing neurologic disability and/or the frequency of clinical relapses in patients with SP-MS, PR-MS, or worsening RR-MS (for example, patients whose neurologic status is significantly abnormal between relapses). Mitoxantrone is not used in the treatment of patients with PP-MS.
Fingolimod (Gilenya®)
Fingolimod (Gilenya®) is a daily oral medication to treat MS that was approved by the US FDA in September 2010 as the first oral medication to treat MS. Although the exact mechanism of action of fingolimod is unclear, it appears to work by reducing the number of lymphocytes (a type of white blood cell that is important for immunity and the inflammation process) in the blood.
Fingolimod is taken daily in capsule form. It is not a cure for MS, but it has been shown to decrease the number of MS flares and slow down the development of physical disability caused by MS.
Like many injectable therapies for MS, the long-term safety of fingolimod is unknown. The most common side effects of fingolimod are headache, flu, diarrhea, back pain, elevations of liver enzymes in the blood, and cough. Other side effects are also possible including eye problems, so those taking this drug should have regular ophthalmologic evaluations.
Multiple Sclerosis - Symptoms at Onset of DiseaseQuestion: The symptoms of multiple sclerosis can vary greatly from patient to patient. What were your symptoms at the onset of your disease?
Muscle spasms are involuntary muscle contractions that come on suddenly and are usually quite painful. Dehydration, doing strenuous exercise in a hot environment, prolonged muscle use, and certain diseases of the nervous system may cause muscle spasms. Symptoms and signs of a muscle spasm include an acute onset of pain and a possible bulge seen or felt beneath the skin where the muscle is located. Gently stretching the muscle usually resolves a muscle spasm.
Itching can be a common problem. Itches can be localized or generalized. There are many causes of itching to include: infection (jock itch, vaginal itch), disease (hyperthyroidism, liver or kidney), reactions to drugs, and skin infestations (pubic or body lice). Treatment for itching varies depending on the cause of the itch.
Impotence, also known as erectile dysfunction, is a common
problem among men characterized by the consistent inability to sustain an
erection sufficient for sexual intercourse or the inability to achieve
ejaculation, or both. Impotence can have emotional causes but most often it is
due to a physical problem.
Overactive bladder is a sudden involuntary contraction of the muscle wall of the bladder causing urinary urgency (an immediate unstoppable need to urinate). Overactive bladder is is a form of urinary incontinence. Treatment options may include Kegel exercises, biofeedback, vaginal weight training, pelvic floor electrical stimulation, behavioral therapy, and medications.
Dysphagia or difficulty in swallowing, swallowing problems. Dysphagia is due to problems in nerve or muscle control. It is common, for example, after a stroke. Dysphagia compromises nutrition and hydration and may lead to aspiration pneumonia and dehydration.
Hydronephrosis is a condition in which the kidney swells, due to a backup of urine. Hydronephrosis generally occurs with another disease.Symptoms of hydronephrosis include nausea, vomiting, urinary tract infection, fever, painful urination, increased urinary frequency and urgency, flank pain, and swelling of the abdomen. Treatment of hydronephrosis depends on the cause.
Neuropathic pain is chronic pain resulting from injury to the nervous system. The injury can be to the central nervous system (brain and spinal cord) or the peripheral nervous system (nerves outside the brain and spinal cord).
Optic neuritis is inflammation of the optic nerve, the structure that connects the eye to the brain. The precise cause of optic neuritis is unknown, but it is thought to be a type of autoimmune disorder. Optic neuritis most commonly develops due to an autoimmune disorder that may be triggered by a viral infection.
There are many types of urinary incontinence (UI), which is the accidental leakage of urine. These types include stress incontinence, urge incontinence, and overflow incontinence. Urinary incontinence in men may be caused by prostate or nerve problems. Treatment depends upon the type and severity of the UI and the patient's lifestyle.
Urinary retention (inability to urinate) may be caused by nerve disease, spinal cord injury, prostate enlargement, infection, surgery, medication, bladder stone, constipation, cystocele, rectocele, or urethral stricture. Symptoms include discomfort and pain. Treatment depends upon the cause of urinary retention.
Vitamin D deficiency has been linked with rickets, cancer, cardiovascular disease, severe asthma in children and cognitive impairment in older adults. Causes include not ingesting enough of the vitamin over time, having limited exposure to sunlight, having dark skin, and obesity. Symptoms include bone pain and muscle weakness. Treatment for vitamin D deficiency involves obtaining more vitamin D through supplements, diet, or exposure to sunlight.
People who have bladder spasms, the sensation occurs suddenly and often severely. A spasm itself is the sudden, involuntary squeezing of a muscle. A bladder spasm, or "detrusor contraction," occurs when the bladder muscle squeezes suddenly without warning, causing an urgent need to release urine. The spasm can force urine from the bladder, causing leakage. When this happens, the condition is called urge incontinence or overactive bladder.
Millions of women suffer from urinary incontinence (UI). UI occurs twice as often in women as in men. There are many types of urinary incontinence: stress incontinence, urge incontinence, overactive bladder, functional incontinence, overflow incontinence, transient incontinence, and mixed incontinence.
The term alternative therapy, in general, is used to describe any medical treatment or intervention that has not been scientifically documented or identified as safe or effective for a specific condition. Alternative therapy encompasses a variety of disciplines that range from diet and exercise to mental conditioning to lifestyle changes.
Double vision (diplopia) is a symptom that my indicate Graves' disease, myasthenia gravis, stroke, multiple sclerosis, Guillain-Barre syndrome, diabetes, cataracts, aneurysm, brain tumor, or migraine. Symptoms and signs include eye pain, droopy eyelids, nausea, headache, and a cross-eyed appearance. Treatment of double vision depends upon the underlying cause.
A nerve problem might affect your bladder control if the nerves that are supposed to carry messages between the brain and the bladder do not work properly. Such problems include urine retention, poor control of sphincter muscles, and overactive bladder. Treatment depends upon the cause of the nerve damage and resulting type of bladder control problem.
Reduction of the sense of smell is termed hyposmia. Total inability to detect odors is termed anosmia. Smell disorders have many causes. Most people who develop a smell disorder have recently experienced an illness or an injury.
