Celecoxib Safety Revisited

The results of a clinical trial (PRECISION)1 comparing

the cardiovascular safety of the COX-2 selective

NSAID celecoxib (Celebrex, and generics) with that

of ibuprofen and naproxen, which are nonselective,

have been described in the lay press in terms that may

overestimate the safety of celecoxib.

NSAID PHARMACOLOGY — NSAIDs inhibit the enzyme

cyclooxygenase (COX), which is required for synthesis

of prostaglandins and thromboxane COX-1 inhibition

blocks the protective effect of prostaglandins on the

gastric mucosa, which can cause gastrointestinal

toxicity, and has an antiplatelet effect that can cause

bleeding COX-2 inhibition produces therapeutic

anti-inflammatory and analgesic effects, but it has effects

on vascular endothelium that can be prothrombotic

Ibuprofen and naproxen inhibit COX-1 more than

COX-2 The COX-2 selective NSAID rofecoxib (Vioxx),

which inhibits COX-2 80 times more than COX-1, was

removed from the market because of cardiovascular

toxicity Celecoxib, which inhibits COX-2 9 times

more than COX-1, also has been associated with an

increased risk of cardiovascular toxicity.2,3

All NSAIDs inhibit renal prostaglandins, decrease

renal blood flow, cause fluid retention, and may cause

hypertension and renal failure, especially in the elderly.4

THE PRECISION TRIAL — A total of 24,081 patients

with osteoarthritis (90%) or rheumatoid arthritis

(10%) and established cardiovascular disease or

increased risk of developing cardiovascular disease

were randomized to receive celecoxib 100 mg twice

daily, ibuprofen 600 mg three times daily, or naproxen

375 mg twice daily; the mean treatment duration was

20.3 months and the mean follow-up period was 34.1

months About 50% of the patients were taking

low-dose aspirin at baseline A primary outcome event

(cardiovascular death, nonfatal myocardial infarction,

or nonfatal stroke) occurred in 188 patients taking celecoxib (2.3%), 201 taking naproxen (2.5%), and 218 taking ibuprofen (2.7%); celecoxib was determined to

be noninferior to both ibuprofen and naproxen with regard to cardiovascular safety.1

SOME LIMITATIONS — By the end of the PRECISION

trial, 68.8% of patients had stopped taking their assigned drug The dosage of celecoxib was limited

to 200 mg per day for patients with osteoarthritis;

as a result, the average daily dose of celecoxib was lower than the doses previously associated with cardiovascular toxicity Increases in the dosage of ibuprofen and naproxen were permitted Ibuprofen and naproxen, but not celecoxib, inhibit aspirin binding to platelet COX-1; thus, the cardioprotective effects of aspirin may have been blunted in patients who were taking ibuprofen or naproxen.5

CONCLUSION — The average dosage of the COX-2

selective NSAID celecoxib (Celebrex, and generics)

used in the PRECISION trial was too low to support the determination that celecoxib is noninferior to ibuprofen and naproxen with regard to cardiovascular safety COX-2 selective NSAIDs cause less gastrointestinal toxicity and bleeding than nonselective NSAIDs, but they may have a prothrombotic effect, and all NSAIDs are nephrotoxic Elderly patients, who are most at risk, should exercise caution in taking any NSAID, includ -ing celecoxib ■

Drugs for Psychotic Disorders

Oral antipsychotic drugs used for treatment of

schizophrenia, schizoaffective disorder, delusional

disorder, and other manifestations of psychosis or

mania are listed in Table 1 on page 161 Parenteral

antipsychotic drugs used for treatment of these

disorders are listed in Table 2 on page 162.

EFFECTIVENESS — Antipsychotic drugs are more

effective in treating the positive symptoms of

schizophrenia (agitation, hallucinations, delusions)

than the negative symptoms (apathy, social withdrawal,

blunted affect).1,2

Oral – Second-generation antipsychotics are used

more commonly than less expensive fi rst-generation

drugs, even though controlled trials generally have

failed to demonstrate a clear advantage in effi cacy,

except with clozapine and possibly olanzapine.3

Clozapine is generally considered the most effective

antipsychotic drug for treatment of schizophrenia.4

It has been effective for treatment of psychotic

symptoms that have not responded to other drugs and

has been more effective than other antipsychotics in

decreasing the risk of suicide.5

Olanzapine has been more effective than aripiprazole,

quetiapine, risperidone, or ziprasidone in reducing

psychotic symptoms.6 Risperidone has been more

effective than quetiapine or ziprasidone.7

The more recently approved antipsychotic drugs

paliperidone,8 asenapine,9 iloperidone,10 lurasidone,11

brexpiprazole,12 and cariprazine13 may be effective for

some patients, but their effi cacy and safety relative to

older drugs remain to be established

Parenteral – Short-acting parenteral antipsychotics

can be helpful for acute treatment of agitation

associated with schizophrenia or bipolar 1 mania

Long-acting parenteral antipsychotics generally have

been used in patients with a history of relapse due to

poor adherence to oral maintenance therapy

Long-acting injectable formulations can improve adherence,

hospitalization and relapse rates, and long-term

outcomes for patients with schizophrenia, even though

a benefi t has not been consistently demonstrated in

trials comparing long-acting injectable formulations

with oral formulations.14,15 In one head-to-head trial,

once-monthly paliperidone palmitate was no more

effective than haloperidol decanoate, which costs

much less.16 Data on newer long-acting parenteral

formulations such as paliperidone palmitate 3-month, olanzapine, and aripiprazole are limited.17,18

Inhaled – The fi rst-generation antipsychotic loxapine

is available as an inhalation powder (Adasuve) for acute

treatment of agitation associated with schizophrenia

or bipolar 1 disorder in patients who are able to use

an inhaler and who are not at risk for bronchospasm.19

ADVERSE EFFECTS — Movement disorders, metabolic

effects, and other adverse effects can interfere with patient adherence to antipsychotic drugs

The FDA requires labels of both fi rst- and second-generation antipsychotics to include a boxed warning about an increased risk of death in elderly patients with dementia-related psychosis.20

First-Generation – All fi rst-generation antipsychotics

have been variably associated with sexual dysfunction, hyperprolactinemia, neuroleptic malignant syndrome, extrapyramidal symptoms, akathisia, and tardive dyskinesia The risk of extrapyramidal symptoms and tardive dyskinesia may be minimized if dosing

is targeted to the lowest dose at which mild extrapyramidal motor effects fi rst appear.21

Chlorpromazine commonly causes sedation, postural

hypotension, and weight gain, as well as anticholin-ergic and occasional extrapyramidal adverse effects

Haloperidol and fluphenazine are less likely to cause

sedation, postural hypotension, anticholinergic effects, or weight gain, but are more likely to cause

extrapyramidal symptoms Perphenazine, loxapine, and molindone are generally less sedating than

chlor-promazine and somewhat less likely than haloperidol and fluphenazine to cause extrapyramidal symptoms

Second-Generation – Second-generation

antipsy-chotics have a relatively lower risk of causing extrapyramidal symptoms and are less likely than fi rst-generation antipsychotics to cause tardive dyskinesia and neuroleptic malignant syndrome, but akathisia

is a persistent problem.22,23 Second-generation

Choice of an Antipsychotic Drug

▶ Clozapine is generally the most effective antipsychotic drug for treatment of schizophrenia, but it is usually reserved for refractory disease because of its adverse effects

▶ Olanzapine may be slightly more effective than other anti-psychotic drugs (except clozapine), but its adverse metabolic effects may make it unacceptable for long-term use

▶ Other second-generation antipsychotics are not clearly more effective than less expensive fi rst-generation drugs, but they are less likely to cause tardive dyskinesia

▶ Long-acting injectable antipsychotics may be useful when adherence is a problem

Despite its structural similarity to clozapine,

olanzapine is unlikely to cause severe neutropenia

or seizures It does cause weight gain and other metabolic adverse effects, including diabetes mellitus Postural hypotension, somnolence, constipation, hyperlipidemia, dizziness, and akathisia can also occur Increases in serum hepatic transaminases have been reported DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome has been reported rarely with olanzapine.27,28

Adverse effects of risperidone have included

parkinsonism, akathisia, dystonia, insomnia, constipation, dizziness, salivary hypersecretion, weight gain, and prolactin elevation (much more than other second-generation antipsychotics except for paliperidone, which is the active metabolite

of risperidone) At doses >6 mg/day, the risk of extrapyramidal symptoms increases with only a modest increase in effi cacy In addition to prolactin

elevation, adverse effects of paliperidone include

antipsychotics have a higher risk than fi rst-generation

drugs of causing metabolic syndrome, including weight

gain, hyperglycemia, and hyperlipidemia Table 3

(see page 163) lists some adverse effects of

second-generation antipsychotics and the relative likelihood

of their occurrence.

Clozapine causes granulocytopenia in about 1%

of patients; weekly monitoring of blood counts is

required It can also cause orthostatic hypotension,

bradycardia, and syncope Seizures occur in 1-4% of

patients and are dose-related Increased salivation and

enuresis can occur.24 Gastrointestinal hypomotility,

which can be severe and result in toxic megacolon, is

common in patients taking clozapine and can result in

life-threatening complications; prophylactic laxatives

are recommended.25 Weight gain and hyperlipidemia

are also common Myocarditis, which often occurs

within the fi rst few weeks of treatment and is fatal in

up to 50% of cases, has been reported in as many as

0.5-3% of patients.26

Aripiprazole can cause anxiety, headache, nausea,

constipation, lightheadedness, agitation, and aka thisia It is less likely than most second-generation antipsychotics to cause hyper lipidemia, hyperglycemia, weight gain, and hyperprolactin-emia.32 Impulse-control problems, such as compulsive eating, shopping, and sexual activity, have been reported rarely.33

Asenapine can cause insomnia, somnolence, nausea,

vom iting, and weight gain.34

In published studies to date, brexpiprazole has been

associated with fewer clinically relevant adverse effects than other antipsychotics; insomnia, weight gain, headache, and agitation have been reported.12,35

Cariprazine can cause akathisia, extrapyramidal

symptoms, tremor, and small changes in meta -bolic parameters.36

extrapyramidal symptoms, nausea, somnolence,

dizzi-ness, tachycardia, and QT interval prolongation.

Quetiapine commonly causes somnolence, dizziness,

constipation, postural hypotension, hyperglycemia,

and weight gain Although its package insert

recommends twice-yearly ophthalmologic monitoring,

clinical use of quetiapine probably does not cause

cataract formation.29

Ziprasidone seldom causes signifi cant weight

gain, hyperlipidemia, or hyperglycemia Its adverse

effects have included mild to moderate

somno-lence, extrapyramidal symptoms and, occasionally,

paradoxical excitement Prolongation of the QT

interval has been reported, but a postmarketing

trial in >18,000 patients did not fi nd an increase in

cardiac deaths with ziprasidone compared to

olanzapine.30 DRESS syndrome has been reported

rarely with ziprasidone.31

Iloperidone can cause orthostatic hypotension,

QT interval prolongation, dizziness, somnolence,

dry mouth, and weight gain, but is relatively free of

extrapyramidal effects, including akathisia.37

Lurasidone can cause akathisia, nausea, extrapyramidal

symptoms, and somnolence, but is among the least

likely to be associated with weight gain.38

PREGNANCY — Data on use of antipsychotic drugs

during pregnancy are limited39; none have been

proven to be teratogenic Chlorpromazine was once

used to treat morning sickness, apparently without

teratogenesis Neonates exposed to antipsychotic

drugs in the third trimester of pregnancy are at risk for

extrapyramidal and withdrawal symptoms following

delivery The risks of hyperglycemia and weight gain

are greater with second-generation antipsychotics,

which have been associated with high birth weight and

babies that are large for gestational age.40 ■
