Dose reference
Human
Standard dosage: Treatment with this combination should be introduced gradually; dosage should be assessed individually and titrated for optimal effect. The following dosage instructions should therefore be regarded as guidelines.Initial therapy: In the early stages of Parkinson’s disease, it is advisable to start treatment with one capsule of this combination 62.5 three to four times daily. As soon as tolerability of the initial dosing schedule is confirmed, the dosage should be increased slowly in accordance with the patient’s response. An optimal effect is generally achieved with a daily dosage of this combination corresponding to 300-800 mg of levodopa 75-200 mg benserazide, to be divided into 3 or more doses. Between 4 and 6 weeks may be needed to achieve the optimal effect. If it proves necessary to further, increase the daily dosage, this should be done on a monthly basis.Maintenance therapy: The average maintenance dosage is 1 capsule of this combination 125 three to six times daily. The number of individual doses (not less than 3) and their distribution throughout the day must be titrated for optimal effect. this combination HBS and this combination dispersible may substitute standard this combination to achieve an optimal effect.
Administration: When taking standard this combination capsules or this combination HBS, patients must always ensure that they swallow the whole capsule without chewing it. this combination dispersible tablets are to be dispersed in a quarter of a glass of water (approx. 25-50 ml). The tablets disintegrate completely, producing a milky-white dispersion within a few minutes. Because of rapid sedimentation, it is advisable to stir the dispersion before drinking. this combination dispersible tablets should be taken within half an hour of preparing the dispersion.Where possible, this combination should be taken at least 30 minutes before or 1 hour after meals, so that the competitive effect of dietary protein on levodopa uptake can be avoided and to facilitate a more rapid onset of action. Undesirable gastrointestinal effects, which may occur mainly in the early stages of the treatment, can largely be controlled by taking this combination with a low protein snack (e.g. biscuits) or liquid or by increasing the dose slowly.

Read moreLevodopa & benserazide is indicated for the treatment of all forms of Parkinson's syndrome with the exception of medicine-induced parkinsonism. Levodopa & benserazide dispersible is a formulation which is suitable for patients with dysphagia (difficulties in swallowing) or who require a formulation with a more rapid onset of action, e.g. patients suffering from early morning and afternoon akinesia, or who exhibit "delayed on" or "wearing off" phenomena. Levodopa & benserazide HBS is indicated for patients presenting with all types of fluctuations in response, especially those related to fluctuations in plasma levels (i.e. "peak dose dyskinesia" and "end of dose deterioration") and for better control of nocturnal symptoms. Further experience is required to determine whether it is also advantageous to use Levodopa & benserazide HBS in new Parkinson patients.

Contraindication Notes:
This combination is contraindicated in: Patients with known hypersensitivity to levodopa or benserazide or any of the excipients. Patients receiving non-selective monoamine oxidase (MAO) inhibitors due to the risk of hypertensive crisis. However, selective MAO-B inhibitors, such as selegiline and rasagiline, or selective MAO-A inhibitors, such as moclobemide, are not contraindicated. Combination of MAO-A and MAO-B inhibitors is equivalent to non-selective MAO inhibition, and hence this combination should not be given concomitantly with this combination. Patients with decompensated endocrine, renal or hepatic function, cardiac disorders, psychiatric diseases with a psychotic component or closed angle glaucoma. Because levodopa may activate a malignant melanoma, this combination should not be used in patients with suspicious, undiagnosed lesions or a history of melanoma. The management of patients with intention tremor and Huntington’s chorea. Patients less than 30 years old (skeletal development must be complete).
Dopamine, which acts as a neurotransmitter in the brain, is not present in sufficient quantities in the basal ganglia of parkinsonian patients. Levodopa or L-DOPA (3,4-dihydroxy phenylalanine) is an intermediate in dopamine biosynthesis. Levodopa (dopamine precursor) is used as a prodrug to increase dopamine levels since it is able to cross the blood-brain barrier whereas dopamine itself cannot. Once levodopa has entered the central nervous system, it is metabolised to dopamine by aromatic L-amino acid decarboxylase After administration, levodopa is rapidly decarboxylated to dopamine in extracerebral as well as cerebral tissues. As a result, most of the levodopa administered is not available to the basal ganglia, and the dopamine produced peripherally frequently causes unwanted effects. It is therefore particularly desirable to inhibit extracerebral decarboxylation of levodopa. This can be achieved by simultaneous administration of levodopa and benserazide, a peripheral decarboxylase inhibitor. This preparation is a combination of these two substances in a ratio of 4:1- this ratio having proved optimal in clinical trials and therapeutic use- and is just as effective as large doses of levodopa given alone.
Pregnancy Category B3. This combination is contraindicated during pregnancy and in women of childbearing potential in the absence of adequate contraception. If pregnancy occurs in a woman taking this combination, the medicine must be discontinued (as advised by the prescribing physician). The safe use of this combination during lactation has not been established. Since it is not known whether benserazide passes into breast milk, mothers requiring this combination treatment should not nurse their infants, since the occurrence of skeletal malformations in the infants cannot be excluded.
Renal impairment: Levodopa and benserazide are both extensively metabolised and less than 10% of levodopa is excreted unchanged through the kidneys. No dose reduction is therefore necessary in case of mild or moderate renal insufficiency. Pharmacokinetic data with levodopa in renal impaired patients are not available. This combination is well tolerated by uraemic patients undergoing haemodialysis.Hepatic impairment: Levodopa is mainly metabolised by the aromatic amino acid decarboxylase that is abundantly present in the intestinal tract, in the kidney and heart in addition to the liver. Pharmacokinetic data with levodopa in hepatic impaired patients are not available.Paediatric use: This combination is contraindicated in patients less than 30 years old
