riluzole - oral, Rilutek
GENERIC NAME: RILUZOLE - ORAL (RIL-ue-zole)
BRAND NAME(S): Rilutek
USES: This medication is used to treat a certain type of nerve disease called amyotrophic lateral sclerosis (ALS, also commonly called Lou Gehrig's disease). Riluzole helps to slow down the worsening of this disease and prolong survival. However, it is not a cure for ALS, and it does not reverse nerve damage or muscle weakness. Riluzole is thought to work by protecting the nerves in the brain and spinal cord from too much of a natural substance called glutamate that may be part of the cause of nerve damage.

ALS vs. MS Differences and Similarities
ALS (amyotrophic lateral sclerosis, Lou Gehrig's disease) and MS (multiple sclerosis) are both diseases of the nervous system (neurodegenerative). ALS is a disease in which the nerve cells in the body are attacked by the immune system, although it's not considered an autoimmune disease by some scientists. MS is an autoimmune disease in which the insulated covering of the nerves (myelin sheath) in the CNS (central nervous system) degenerate, or deteriorate.
Scientists don't know the exact cause of either problem. However, they have discovered that mutations in the gene that produces the SOD1 enzyme were associated with some cases of familial ALS. Scientists also theorize that multiple sclerosis may be caused by infection or vitamin D deficiency. ALS occurs between 50-70 years of age (the average age of occurrence ALS is 55), and mostly affects men. While MS occurs between 20-60 years of age, and mostly affects women. About 30,000 people in the US have ALS, and an average of 5,000 new diagnoses per year (that's about 15 new cases per week). Worldwide, MS affects more than 2.3 million people, with about 10,000 new cases diagnosed each year (that's about 200 new diagnoses per week).
Some of the signs and symptoms of both disease are:
- Muscle weakness
- Involuntary muscle spasms
- Problems walking
- Slurred speech
- Difficulty swallowing
ALS signs and symptoms that are different from MS include:
- Problems holding the head upright
- Clumsiness and the tendency to trip and fall
- Muscle cramps and twitches
- Difficulty holding objects
- Uncontrollable periods of laughing or crying
MS signs and symptoms that are different from ALS include:
- Vision problems
- Sexual dysfunction
- Cognitive problems (slowed or fuzzy memory)
- Depression and mood swings
- Problems with the gut
- Problems with mobility
While there is no cure for either disease, however the prognosis and life expectancy are different. Multiple sclerosis is not a fatal condition, while ALS progresses rapidly and leads to death.
Amyotrophic Lateral SclerosisAmyotrophic lateral sclerosis (ALS, Lou Gehrig's disease) is a neurological disease that progresses rapidly. The disease attacks the nerve cells responsible for the control of voluntary muscles. Early symptoms include cramping, twitching, or stiffness of the muscles; slurred nasal speech; difficulty swallowing or chewing, and muscle weakness in an arm or leg. Currently, the cause of ALS is not known. ALS is a fatal disease. No cure has been found for ALS, however, the drug riluzole (Rilutek) is FDA approved, and this drug reduces the damage to motor neurons by decreasing the release of glutamate.
