Indications

Twindopa Tablet is indicated for:

• Treatment of Parkinson’s disease and Parkinsonian syndromes

• Relief of rigidity and bradykinesia

• Management of tremor, dysphagia, sialorrhea, and postural instability associated with Parkinson’s disease

• Improvement of motor recovery when Levodopa plus Carbidopa is administered before physiotherapy in post-stroke patients

Pharmacology

Levodopa is the metabolic precursor of dopamine. It crosses the blood–brain barrier and is converted into dopamine in the brain, which helps alleviate the symptoms of Parkinson’s disease.
Carbidopa is a dopa decarboxylase inhibitor that prevents the peripheral conversion of Levodopa into dopamine. This action increases the availability of Levodopa in the brain and reduces peripheral side effects, thereby enhancing therapeutic efficacy.

Dosage and Administration

• Dosage should be individualized based on patient response and clinical condition.

• Therapy may be initiated with one tablet three or four times daily.

• Gradual titration may be required to achieve optimal symptom control.

• When higher Levodopa requirements are needed, higher-strength combinations may be substituted under medical supervision.

• Experience with daily Carbidopa doses above 200 mg is limited.

Patients should follow the prescribing physician’s instructions carefully.

Drug Interactions

• May cause symptomatic postural hypotension when used with antihypertensive medicines

• Tricyclic antidepressants may rarely cause hypertension or dyskinesia

• Iron salts (ferrous sulphate or gluconate) may reduce bioavailability

• Dopamine-2 receptor antagonists, isoniazid, phenytoin, and papaverine may reduce therapeutic effects

• Concomitant use with selegiline may cause severe orthostatic hypotension
