Medication Summary

The goals of pharmacotherapy are to reduce symptoms, reduce morbidity, and prevent complications.

Next

Benzodiazepines

Class Summary

Most frequently cited as useful in the treatment of stiff person syndrome. Activate the GABA-A receptor to enhance central inhibitory circuits. Benzodiazepines include diazepam (Valium) or lorazepam (Ativan).

View full drug information

Diazepam (Valium)

 

Depresses all levels of CNS (eg, limbic and reticular formation), possibly by increasing activity of GABA.

Individualize dosage and increase cautiously to avoid adverse effects.

View full drug information

Lorazepam (Ativan)

 

Sedative hypnotic with short onset of effects and relatively long half-life.

By increasing the action of GABA, which is a major inhibitory neurotransmitter in the brain, may depress all levels of CNS, including limbic and reticular formation.

Immune modulators

Class Summary

These agents alter immune response to antigens. IVIG can be used.

View full drug information

Immune globulin intravenous (Gamimune, Gammagard, Sandoglobulin)

 

Neutralizes circulating antibodies through anti-idiotypic antibodies. Down-regulates proinflammatory cytokines, including INF-gamma; blocks Fc receptors on macrophages; suppresses inducer T and B cells and augments suppressor T cells; blocks complement cascade; promotes remyelination; may increase CSF IgG (10%).

Skeletal muscle relaxants

Class Summary

These agents increase activity of central inhibitory systems. Theoretically less sedating in relationship to GABA-A agonists such as benzodiazepines. Baclofen can be used.

View full drug information

Baclofen (Lioresal)

 

May induce hyperpolarization of afferent terminals and inhibit both monosynaptic and polysynaptic reflexes at the spinal level.
