## Cautions for Ipratropium (EENT)

### Contraindications

- Known hypersensitivity to ipratropium or any ingredient in the formulation, or to atropine or its derivatives.

### Warnings/Precautions

#### Sensitivity Reactions

##### Hypersensitivity Reactions

Immediate hypersensitivity reactions, including urticaria, angioedema, rash, bronchospasm, and oropharyngeal edema, may occur.

#### General Precautions

##### Ocular Effects

Caution in patients with angle-closure glaucoma. Ocular pain or precipitation or worsening of angle-closure glaucoma reported following inadvertent contact of the drug with the eyes.

##### Genitourinary Effects

Caution in patients with prostatic hypertrophy or bladder neck obstruction.

#### Specific Populations

##### Pregnancy

Category B.

##### Lactation

Not known whether ipratropium is distributed into milk following intranasal administration. Caution advised.

##### Pediatric Use

Safety established based on studies in children.

Efficacy based on extrapolation from studies in adults with perennial rhinitis and adults and adolescents with common cold or seasonal allergic rhinitis and on the likelihood that the disease course, pathophysiology, and the drug’s effect in children are similar to those in adults.

Safety and efficacy of 0.03% nasal spray not established in children <6 years of age.

Safety and efficacy of 0.06% nasal spray not established in children <5 years of age.

### Common Adverse Effects

Nasal dryness, epistaxis.

## Interactions for Ipratropium (EENT)

Limited systemic absorption of intranasal ipratropium minimizes potential for interactions with systemically administered drugs.

### Antimuscarinic Agents

Potential for additive pharmacologic effect with other antimuscarinic agents, including orally inhaled ipratropium.

## Ipratropium (EENT) Pharmacokinetics

### Absorption

#### Bioavailability

<20% following intranasal administration.

#### Onset

Common cold: 1 hour.

Perennial rhinitis: 1 day.

### Distribution

#### Plasma Protein Binding

0–9% (albumin and α1-acid glycoprotein).

### Elimination

#### Metabolism

Metabolized to ester hydrolysis products (tropic acid and tropane).

#### Elimination Route

Following IV administration, approximately 50% of dose excreted in urine as unchanged drug within 24 hours. Following intranasal administration at recommended dosages, mean percentage of dose excreted in urine as unchanged drug generally <10%.

#### Half-life

1.6 hours.

## Stability

### Storage

#### Intranasal

##### Solution

15–30°C; avoid freezing.

## Actions

- Nonselective competitive antagonist at muscarinic receptors.

- When applied locally, inhibits secretions from serous and seromucous glands lining the nasal mucosa.

- Ipratropium nasal spray has not produced appreciable changes in pupillary diameter, heart rate, or blood pressure in children or adults.

- Ipratropium nasal spray does not alter physiologic nasal functions such as sense of smell, ciliary beat frequency, mucociliary clearance, or air conditioning capacity of nose.

## Advice to Patients

- Provide careful instruction on priming the pump and administration.

- Importance of providing patient a copy of manufacturer’s patient information.

- Risk of temporary blurring of vision, precipitation or worsening of angle-closure glaucoma, or ocular pain if ipratropium comes into direct contact with the eye. Avoid spraying ipratropium nasal spray in or around the eyes.

- Importance of notifying clinician if ocular pain, blurred vision, excessive nasal dryness, or episodes of nasal bleeding develop.

- Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.

- Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs.

- Importance of informing patients of other important precautionary information. (See Cautions.)
