Carbidopa-levodopa is a combination medication used in the treatment of the symptoms of Parkinson’s disease and Parkinson-like symptoms, which are often seen in conditions such as dopamine transporter deficiency syndrome and certain forms of secondary parkinsonism.

Carbidopa-Levodopa combines two different drugs, Carbidopa and Levodopa, into one medication.

• Levodopa is a precursor of dopamine, a neurotransmitter that is deficient in the brains of people with Parkinson’s disease.
• Carbidopa, on the other hand, is added to inhibit the breakdown of Levodopa before it reaches the brain.

This combination allows a greater amount of Levodopa to reach the brain where it can be converted into dopamine.

Carbidopa-Levodopa belongs to a class of medications known as dopaminergic drugs, which are used to treat disorders characterized by low levels of dopamine in the brain. Levodopa falls under the subcategory of dopamine precursors since it is directly converted to dopamine in the brain. Carbidopa is classified as a dopa-decarboxylase inhibitor, as it prevents the premature conversion of Levodopa to dopamine outside the brain, thereby increasing its availability in the central nervous system.

Carbidopa-Levodopa is used to manage the symptoms of Parkinson’s disease such as tremors, rigidity, and bradykinesia (slowness of movement).

It is also indicated for the treatment of Parkinsonism caused by encephalitis, certain medications such as antipsychotics, and carbon monoxide intoxication.

The medication comes in tablet and capsule forms including immediate-release, extended-release, and controlled-release formulations.

Frequently Asked Questions About Carbidopa and Levodopa

What Is Carbidopa/Levodopa Used to Treat?

Carbidopa-Levodopa is primarily used to treat the symptoms of Parkinson’s disease and other conditions that present with low levels of dopamine in the brain. It can also be used to manage Parkinson-like symptoms caused by certain medications, infections, or toxic substances.

How Does Carbidopa-Levodopa Work?

Carbidopa-Levodopa works by increasing the levels of dopamine in the brain.

Levodopa works by crossing the blood-brain barrier – a barrier that protects the brain but also restricts many medications from entering – and then being converted into dopamine. This newly synthesized dopamine then helps to restore the dopamine deficiency in the brain, which improves the motor symptoms of Parkinson’s disease.

Carbidopa, on the other hand, does not cross the blood-brain barrier. Its primary role is to inhibit the enzyme dopa-decarboxylase in the peripheral tissues. This enzyme would normally convert Levodopa to dopamine outside the brain, which not only reduces the amount of Levodopa available to the brain but can also lead to side effects like nausea and cardiovascular issues. By inhibiting this enzyme, Carbidopa ensures that more Levodopa reaches the brain and also reduces peripheral side effects.

What Are the Most Common Side Effects of Carbidopa/Levodopa?

The most common side effects revolve around the gastrointestinal system and include nausea, loss of appetite, dry mouth, and dizziness. It may also cause headaches, trouble sleeping, and even muscle twitching.
