For example, its effects are enhanced by ibuprofen and cimetidine (used to treat stomach ulcers) and reduced by phenytoin and alcohol.

Because the drug is not converted into dopamine outside of the brain, this greatly increases the effective dose of levodopa and reduces peripheral side effects. This combination seems to be the best treatment for most Parkinsons patients, at least in the early stages. The site of decarboxylation of levodopa in patients with Parkinsons disease is uncertain, but it may be that there is sufficient enzyme in the remaining dopamine nerve terminals or that conversion takes place in other neurons as they also contain decarboxylase enzymes.

For abdominal examinations using barium contrast agents, laxatives and bowel evacuants are necessary to empty the bowel. The most commonly used preparation for this purpose is Picolax, which is a combination of a stimulant laxative and an osmotic laxative.
