Symmetrel general information

What is Symmetrel used for?

Symmetrel capsules 100mg are used to treat Parkinson's disease, a neurological disorder that is either idiopathic, which means that its cause is unknown or secondary to a known cause such as stroke, head trauma or as a side effect of medication, particularly neuroleptic antipsychotics. Symmetrel 100 may be used alone as monotherapy, or in combination with other medications, like anticholinergic drugs or levodopa and helps relieve symptoms of Parkinsonism and Parkinson's disease, including tremor, bradykinesia (slowness of movement) and loss of balance. Symmetrel capsules 100mg are also used as prophylaxis to prevent signs and symptoms of infection caused by influenza A virus, particularly for those at high risk of infection, if vaccination is unavailable or contraindicated, and for those at risk of serious illness if they were to become infected, such as being immunocompromised or having lung problems; also to treat flu-like symptoms if administered within 48 hours.

How does Symmetrel work?

Symmetrel capsules 100mg contain amantadine, which is an antiparkinsonian drug with virostatic properties. The abnormal movements associated with Parkinsonism and Parkinson's disease are caused by low levels of dopamine, a neurotransmitter (chemical that allows communication between nerve cells) produced by certain neurons (nerve cells) in the brain and plays an important role in controlling muscle function and movement; it is important to have the correct levels of dopamine. The loss of dopamine seen in Parkinson's disease is due to slow and progressive destruction of the neurons that produce the dopamine in a certain area of the brain called the substantia nigra. Amantadine in Symmetrel 100 is thought to increase the amount of dopamine in the brain by enhancing the release of dopamine from central neurons and by delaying its re-uptake from the synapse, the gap between nerve cells across which chemical messages are sent from one nerve cell to another. The increase in dopamine levels helps the brain control muscle function and restore normal movement. Amantadine in Symmetrel 100 is also thought to exert some anticholinergic activity, which means that it blocks the binding of the neurotransmitter acetylcholine to its receptor in nerve cells and this action helps prevent the involuntary movements associated with Parkinsonism. The mechanism of action by which Symmetrel 100 prevents the growth of influenza A virus is not known but it is thought to be due to interference with a viral protein needed for the virus to infect the host cell and this inhibits the early stage of replication of the influenza A virus and checks the growth of virus.

What does Symmetrel contain?

Symmetrel capsules 100mg contain the active ingredient amantadine hydrochloride, used to treat Parkinson's disease and to treat and prevent symptoms of influenza A virus.

Treating symptoms of influenza A infection with Symmetrel

Symmetrel capsules 100mg contain amantadine, which is an antiparkinsonian drug with influenzal virostatic properties, which means that it specifically blocks the growth of the Influenza A virus. Although the mechanism of action by which Symmetrel 100 prevents the growth of influenza A virus is not known it is thought to be due to interference with a viral protein needed for the virus to infect the host cell and this inhibits the early stage of replication of the influenza A virus. Symmetrel capsules 100mg are used as prophylaxis to prevent signs and symptoms of infection caused by influenza A virus, particularly for those at high risk of infection, if vaccination is unavailable or contraindicated, and for those at risk of serious illness if they were to become infected, such as being immunocompromised or having lung problems; also to treat flu-like symptoms if administered within 48 hours.
