Un nuevo preparado de levodopa benserazida en parkinsonianos con fluctuaciones motoras refractarias a tratamientos con L-dopa standard. / [A new levodopa benserazide preparation for Parkinsons disease with motor fluctuations refractory to standard L-dopa]

ABSTRACT

As Parkinsons disease worsens, many patients develop motor fluctuations which usually correlate directly or indirectly with L-dopa plasma levels. A new L-dopa-benserazide HBS preparation (Madopar) a control release pharmaceutical formulation which is activated when it contacts gastric fluid thus providing more stable L-dopa plasma levels, was assayed. Ten patients with a diagnosis of idiopathic Parkinsons disease and motor fluctuations otherwise unresponsive to conventional therapy were selected. The average age was 62 years and the duration of the disease 9 years. The motor status was evaluated on an hourly basis with the Kings College Parkinsons disease rating scale; in addition, a nocturnal disability scale (Lees) was used. Out of the 10 patients, 2 dropped out within the first month due to worsening of parkinsonian signs, while 7 of the remainders preferred HBS preparation to the previous treatment. The number of off hours in this group was reduced by 58
