What is Sinemet?

Sinemet (carbidopa-levodopa) is a combination of an inhibitor of aromatic amino acid decarboxylation and an aromatic amino acid used to treat Parkinson symptoms such as

  • muscle stiffness,
  • tremors,
  • spasms,
  • and poor muscle control.
Sinemet is also used to treat Parkinson symptoms caused by carbon monoxide poisoning or manganese intoxication.

What is Stalevo?

Stalevo (carbidopa, levodopa and entacapone) is a combination of several medications used to treat Parkinson symptoms such as muscle stiffness, tremors, spasms, and poor muscle control. Levodopa is converted to a chemical called dopamine in the brain. Symptoms of Parkinson's disease may be caused by low levels dopamine in the brain. Carbidopa helps prevent the breakdown of levodopa before it can reach the brain and take effect. When used with carbidopa and levodopa, entacapone increases levels of levodopa in the body.

What Drugs Interact With Sinemet?

Sinemet may interact with metoclopramide, isoniazid, phenytoin, papaverine, antidepressants, or blood pressure medications.

Sinemet may also interact with other Parkinson's medications or medicines to treat psychiatric disorders.

What Drugs Interact With Stalevo?

Stalevo may interact with other Parkinson's medications, metoclopramide, isoniazid, phenytoin, papaverine, blood pressure medications, antidepressants, or medicines to treat psychiatric disorders.

Stalevo may also interact with cholestyramine, dobutamine, epinephrine, isoproterenol, methyldopa, papaverine, antibiotics, cold or allergy medicine, narcotics, sleeping pills, muscle relaxers, medicine for seizures, or anti-anxiety medications.

How Should Sinemet Be Taken?

Starting dosage is one tablet of Sinemet 25-100 (carbidopa-levodopa) three times a day. Dosage may be increased by one tablet every day or every other day, as necessary, until a dosage of eight tablets a day is reached.

How Should Stalevo Be Taken?

The optimum daily dosage of Stalevo must be determined for each patient. Therapy should be individualized and adjusted according to the desired therapeutic response.
