Present Illness

--------------------------------------------------------------------------------

This 74-year-old female is a patient of 1). old CVA with left side

weakness 2). DJD s/p laminectomy 10 years ago. 3).left renal stone s/p

ESWL and right renal atrophy. She had regular medical control at MMH.

This time, she has bedridden for about 4 month. This time, she has

suffered from turbid urine for about 3 days and consciouness drowsy

since this morning. Therefore, she was brought to our ER for help. She

denied fever, cough and abdominal pain.

At ER, BT 37.1 degrees, pyuria and turbid urine was noticed.

Laboratory revealed WBC 21250/ul with seg 93%, Hb 7.3, BUN 58.5,

Cr 3.1. Thus, under the impression of urinary tract infection, she was

admitted to our ward for the further management.

Extrapyramidal Reactions Populations most at risk for extrapyramidal reactions include young women, children, the elderly, diabetics, patients with

neurologic disorders and patients taking concurrent neuroleptic medications.[61,62] Genetic factors may also play a role

as polymorphisms of CYP2DG have been demonstrated to decrease themetabolism of metoclopramide and increase the

risk for extrapyramidal reactions.[63] The incidence of these reactions also increases in patients receiving higher

intravenous doses. In 479 reports of metoclopramide-related extrapyramidal reactions in the UK from 1967–1982, 455

were for acute dystonias, 20 for parkinsonism and four for TD.[64]

Acute Dystonic Reactions Acute dystonic reactions are the most frequent extrapyramidal side effects (EPS) from metoclopramide and typically

occur within 24–48 h of initiating treatment, thus affecting approximately 0.2–6% of patients taking metoclopramide and

the incidence increases with higher doses.[64] Dystonia consists of spasmodic or sustained involuntary muscle

contractions resulting in twisting, repetitive movements or abnormal postures. It can present as facial spasm, torticollis,

oculogyric crisis, trismus, tortipelvic (abdominal rigidity) or opisthotonic (spasm of the entire body). Acute dystonic

reactions typically resolve with discontinuation of the drug.[65]

Akithisia Akithisia presents with subjective feelings of inner restlessness as well as objective findings of motor restlessness.

Incidence ranges from 10 to 25% depending on the mode of metoclopramide administration.[66,67] Oral and

intramuscular formulations have a lower rate of akithisia compared with intravenous administration. Furthermore, the

speed of administration of intravenous metoclopramide also appears to influence the risk of akithisia. In one report,

akithisia was reduced from 11.1 to 0% when 10 mg of metoclopramide were administered intravenously

over 2 versus 15 min.[68]

Drug-induced Parkinsonism Prolonged therapy with metoclopramide can result in Parkinsonian-like symptoms, including bradykinesia, tremor and

rigidity. Incidence is unknown, but one series found a fourfold increased risk of developing drug-induced Parkinsonism in

those taking metoclopramide compared with controls.[65] Another series found that patients on metoclopramide had a

threefold increased risk of starting anti-Parkinsonian therapy compared with nonusers.[69] Parkinsonian symptoms

generally resolve within 2–3 months of discontinuation of metoclopramide.

Tardive Dyskinesia The most feared complication of chronic metoclopramide use is TD, which is characterized by involuntary movements of

the face, tongue or extremities. National guidelines[59,70] suggest the prevalence of TD ranges from 1 to 15% after usage

of metoclopramide for at least 3 months and may not reverse even after discontinuation of the medication.[16,65] As a

result, in 2009, the FDA came out with a black-box warning that must be attached to all metoclopramide labeling, which

warns against chronic use except in rare cases. However, a recent review by Rao et al. estimated the risk of TD from

metoclopramide use to be less than 1%, much less than the estimated 1–15% suggested by national

guidelines.[14] Interestingly, the use of metoclopramide and concurrent rise in metoclopramide-induced TD has been

increasing since 2000, which is also the year that Cisapride (Apotex Inc., Ontario, Canada) was withdrawn from the

market.[16]
