Drugs are usually administered intravenously by means of infusions. This allows them to enter the bloodstream directly and thus have a faster and stronger effect.
In the neuropsychiatric field, infusions are used for the supply of high doses of cortisone in acute attacks of multiple sclerosis, for antibiotic or antiviral treatment of acute inflammations of the peripheral and central nervous system.
They are also used to compensate for vitamin B deficiencies, to treat polyneuropathies with alpha lipoic acid or to treat severe Parkinson’s disease with amantadine. In the field of psychiatry, infusions are usually used to treat severe depression.
