Interactions The vitamin pyridoxine (B6) increases the peripheral breakdown of levodopa and diminishes its effectiveness (Figure 8.6). Concomitant administration of levodopa and monoamine oxidase (MAO) inhibitors, such as phenelzine (see p. 124), can produce a hypertensive crisis caused by enhanced catecholamine production therefore, caution is required when they are used simultaneously. In many psychotic patients, levodopa exacerbates symptoms, possibly through the buildup of central amines. In patients with glaucoma, the drug can cause an increase in intraocular pressure. Cardiac patients should be carefully monitored because of the possible development of cardiac arrhythmias. Antipsychotic drugs are contraindicated in parkinsonian patients, since these block dopamine receptors and produce a parkinsonian syndrome themselves.

Vitamin (pyridoxine) and two related compounds (pyridoxamine, pyridoxal 4-deoxypyridoxine internal standard) were isolated from pork meat and separated on a 30 C C g column (2 = 290 nm, ex 395 nm, em) using an aqueous 0.01 M H2SO4 mobile phase [1582]. Peak shapes were excelloit and elution was complete in 15 min. A table showing the effect of changes in sulfuric acid concentration on retention time is presented. Reported linear ranges of 0.0015-0.8 pg/mL were reported.
