The conducted study of the effectiveness of L-DOPA in its long-term (up to 7 years) continuous administration to parkinsonic patients depicted a high therapeutical action of the drug for the first 6 months of the treatment. L-DOPA administration up to 3 years had an antiparkinsonic action approximately in half of the patients. A further prolongation of treatment period decreased L-DOPA effectiveness even more. The increase of the doses in order to raise a therapeutical effect was impossible due to the appearance of side-effects characteristic of L-DOPA. The longitudinal biochemical studies on biogenic amines in those patients' urine established a correlation with the clinical state. The obtained biochemical data permitted to assume an acceleration of extracerebral metabolism of monoamines in L-DOPA treatment for 1--3 years and further on the decrease of sensitivity of CNS dophaminergic neurons to administered L-DOPA. The methods of increasing the effectivity of L-DOPA use in parkinsonism are given. |
