What Is Bendopa 100 mg+25 mg Indications and Uses?

This immediate release capsule is indicated for the treatment of all forms of Parkinson's syndrome with the exception of medicine-induced Parkinsonism. On the other hand, controlled release capsule indicated for patients presenting with all types of motor 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.

Pharmacology (Source, Chemical and Physical Composition) Of Bendopa 100 mg+25 mg

This capsule is an anti-Parkinson’s agent. 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 metabolized to dopamine by aromatic L-amino acid decarboxylase. After administration, levodopa is rapidly decarboxylases to dopamine in extra-cerebral 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 side effects. It is therefore particularly desirable to inhibit extra-cerebral decarboxylation of levodopa. This can be achieved by simultaneous administration of levodopa-benserazide capsule, a peripheral decarboxylase inhibitor. Levodopa- benserazide capsule 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.

Drug Interactions of Bendopa 100 mg+25 mg

Neuroleptics, opioids and antihypertensive medications containing reserpine inhibit the action of levodopa and benserazide capsule. It should not be administered concomitantly with sympathomimetic (agents such as adrenaline, noradrenaline, isoproterenolor amphetamine which stimulate the sympathetic nervous system) as levodopa may potentiate their effects. Should concomitant administration this capsule prove necessary, dose surveillance of the cardiovascular system is essential and the dose of the sympathomimetic agents may need to be reduced. Concomitant administration of antipsychotics with dopamine-receptor blocking properties, particularly D2-receptor antagonists might antagonize the antiparkinsonian effects of levodopa-benserazide capsule. This capsule should be discontinued 12-48 hours before surgical intervention requiring general anesthesia with halothane as fluctuations in blood pressure and/or arrhythmias may occur.
