1. What Glentek 50 mg film-coated tablets is and what it is used for

What Glentek 50 mg Film-coated Tablets are

The active substance in Glentek is riluzole which acts on the nervous system.

What Glentek 50 mg Film-coated Tablets are used for

Glentek is used in patients with amyotrophic lateral sclerosis (ALS).

ALS is a form of motor neurone disease where attacks of the nerve cells responsible for sending instructions to the muscles lead to weakness, muscle waste and paralysis.

The destruction of nerve cells in motor neurone disease may be caused by too much glutamate (a chemical messenger) in the brain and spinal cord. Glentek stops the release of glutamate and this may help in preventing the nerve cells being damaged.

Please consult your doctor for more information about ALS and the reason why this medicine has been prescribed for you.
