NebuPent
Overview
What is NebuPent?
NebuPent (pentamidine isethionate), an antifungal agent, is a nonpyrogenic lyophilized product. After reconstitution with Sterile Water for Injection, USP, NebuPent is administered by inhalation via the Respirgard II nebulizer [Marquest, Englewood, CO] (see ).
Pentamidine isethionate, 4,4’-[1,5-pentane-diylbis(oxy)]bis-benzenecarboximidamid, is a white crystalline powder soluble in water and glycerin and insoluble in ether, acetone, and chloroform.
CHNO•2CHOS 592.68
Each vial contains 300 mg pentamidine isethionate.

How should I use NebuPent?
NebuPent is indicated for the prevention of pneumonia (PJP) in high-risk, HIV-infected patients defined by one or both of the following criteria:
i. a history of one or more episodes of PJP
ii. a peripheral CD4+ (T4 helper/inducer) lymphocyte count less than or equal to 200/mm.
These indications are based on the results of an 18-month randomized, dose-response trial in high risk HIV-infected patients and on existing epidemiological data from natural history studies.
The patient population of the controlled trial consisted of 408 patients, 237 of whom had a history of one or more episodes of PJP. The remaining patients without a history of PJP included 55 patients with Kaposi’s sarcoma and 116 patients with other AIDS diagnoses, ARC or asymptomatic HIV infection. Patients were randomly assigned to receive NebuPent via the Respirgard II nebulizer at one of the following three doses: 30 mg every two weeks (n=135), 150 mg every two weeks (n=134) or 300 mg every four weeks (n=139). The results of the trial demonstrated a significant protective effect (p<0.01) against PJP with the 300 mg every four week dosage regimen compared to the 30 mg every two week dosage regimen. The 300 mg dose regimen reduced the risk of developing PJP by 50 to 70% compared to the 30 mg regimen. A total of 293 patients (72% of all patients) also received zidovudine at sometime during the trial. The analysis of the data demonstrated the efficacy of the 300 mg dose even after adjusting for the effect of zidovudine.
The results of the trial further demonstrate that the dose and frequency of dosing are important to the efficacy of NebuPent prophylaxis in that multiple analyses consistently demonstrated a trend toward greater efficacy with 300 mg every four weeks as compared to 150 mg every two weeks.
No dose-response was observed for reduction in overall mortality; however, mortality from PJP was low in all three dosage groups.
IMPORTANT: NEBUPENT MUST BE DISSOLVED ONLY IN STERILE WATER FOR INJECTION, USP. DO NOT USE SALINE SOLUTION FOR RECONSTITUTION BECAUSE THE DRUG WILL PRECIPITATE. DO NOT MIX THE NEBUPENT SOLUTION WITH ANY OTHER DRUGS. DO NOT USE THE RESPIRGARD

What should I look out for while using NebuPent?
NebuPent is contraindicated in patients with a history of an anaphylactic reaction to inhaled or parenteral pentamidine isethionate.
The potential for development of acute PJP still exists in patients receiving NebuPent prophylaxis. Therefore, any patient with symptoms suggestive of the presence of a pulmonary infection, including but not limited to dyspnea, fever or cough, should receive a thorough medical evaluation and appropriate diagnostic tests for possible acute PJP as well as for other opportunistic and nonopportunistic pathogens. The use of NebuPent may alter the clinical and radiographic features of PJP and could result in an atypical presentation, including but not limited to mild disease or focal infection.
Prior to initiating NebuPent prophylaxis, symptomatic patients should be evaluated appropriately to exclude the presence of PJP. The recommended dose of NebuPent for the prevention of PJP is insufficient to treat acute PJP.
What might happen if I take too much NebuPent?
Overdosage has not been reported with NebuPent. The symptoms and signs of overdosage are not known.
A serious overdosage, to the point of producing systemic drug levels similar to those following parenteral administration, would have the potential of producing similar types of serious systemic toxicity. (See ).
Available clinical pharmacology data (see ) suggest that a dose up to 40 times the recommended NebuPent dosage would be required to produce systemic levels similar to a single 4 mg/kg intravenous dose.
How should I store and handle NebuPent?
Store at 20° to 25°C (68° to 77°F) [See USP Controlled Room Temperature].Dispense in a tight container as defined in the USP, with a child-resistant closure (as required).KEEP THIS AND ALL MEDICATIONS OUT OF THE REACH OF CHILDREN.Store at 20° to 25°C (68° to 77°F) [See USP Controlled Room Temperature].Dispense in a tight container as defined in the USP, with a child-resistant closure (as required).KEEP THIS AND ALL MEDICATIONS OUT OF THE REACH OF CHILDREN.Store at 20° to 25°C (68° to 77°F) [See USP Controlled Room Temperature].Dispense in a tight container as defined in the USP, with a child-resistant closure (as required).KEEP THIS AND ALL MEDICATIONS OUT OF THE REACH OF CHILDREN.Store dry product at 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature].Protect the dry product and the reconstituted solution from light.Store dry product at 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature].Protect the dry product and the reconstituted solution from light.

Drugs that inhibit alprazolam metabolism via cytochrome P450 3A
Drugs demonstrated to be CYP3A inhibitors of possible clinical significance on the basis of clinical studies involving alprazolam (caution is recommended during coadministration with alprazolam)
Fluoxetine—Coadministration of fluoxetine with alprazolam increased the maximum plasma concentration of alprazolam by 46%, decreased clearance by 21%, increased half-life by 17%, and decreased measured psychomotor performance.
Propoxyphene—Coadministration of propoxyphene decreased the maximum plasma concentration of alprazolam by 6%, decreased clearance by 38%, and increased half-life by 58%.
Oral Contraceptives—Coadministration of oral contraceptives increased the maximum plasma concentration of alprazolam by 18%, decreased clearance by 22%, and increased half-life by 29%.
Drugs and other substances demonstrated to be CYP3A inhibitors on the basis of clinical studies involving benzodiazepines metabolized similarly to alprazolam or on the basis of studies with alprazolam or other benzodiazepines (caution is recommended during coadministration with alprazolam)
Available data from clinical studies of benzodiazepines other than alprazolam suggest a possible drug interaction with alprazolam for the following: diltiazem, isoniazid, macrolide antibiotics such as erythromycin and clarithromycin, and grapefruit juice. Data from studies of alprazolam suggest a possible drug interaction with alprazolam for the following: sertraline and paroxetine. However, data from an drug interaction study involving a single dose of alprazolam 1 mg and steady state dose of sertraline (50 to 150 mg/day) did not reveal any clinically significant changes in the pharmacokinetics of alprazolam. Data from studies of benzodiazepines other than alprazolam suggest a possible drug interaction for the following: ergotamine, cyclosporine, amiodarone, nicardipine, and nifedipine. Caution is recommended during the coadministration of any of these with alprazolam (see ).
