CLINICAL PHARMACOLOGY

Chlorpheniramine maleate is an alkylamine-type antihistamine that possesses anticholinergic and sedative effects. Antihistamines competitively antagonize histamine at the H1 receptor site. Thus, activation of H1 receptors by released histamine which results in increased vascular permeability, increased mucus production, pruritus and sneezing is prevented.

Phenylephrine is a sympathomimetic amine, acts directly on adrenergic receptors in the mucosa of the respiratory tract to produce vasoconstriction that increases peripheral resistance, resulting in an increase in both systolic and diastolic blood pressure. Accompanying the pressor response is a marked reflex bradycardia due to increased vagal activity. It produces vasoconstriction that lasts longer than that produced by ephedrine and epinephrine, and in therapeutic doses, produces little or no central nervous system (CNS) stimulation. Phenylephrine has reduced bioavailability from the gastrointestinal tract because of first pass metabolism by monoamine oxidase in the stomach and liver.

Methscopolamine Nitrate is a quaternary ammonium derivative of the anticholinergic scopolamine which possesses the peripheral actions of the belladonna alkaloids, but does not exhibit the central actions because of its lack of ability to cross the blood-brain barrier. It competitively inhibits the action of acetylcholine at muscarinic receptors.

INDICATIONS AND USAGE

For the temporary relief of symptoms associated with allergic rhinitis.

CONTRAINDICATIONS

This product is contraindicated in patients with a hypersensitivity or idiosyncratic reaction to chlorpheniramine maleate, methscopolamine nitrate or phenylephrine hydrochloride. This product is also contraindicated in nursing mothers, and in patients with the following conditions: severe hypertension; severe coronary artery disease; narrow-angle glaucoma; urinary retention; hyperthyroidism; peptic ulcer; asthma attack; MAOI therapy (or for 2 weeks after stopping MAOI therapy). Sympathomimetic amines may produce CNS stimulation and convulsions or cardiovascular collapse with accompanying hypotension. The elderly (60 years and older) are more likely to exhibit adverse reactions.

WARNINGS

Do not exceed recommended dosage. If nervousness, dizziness, or sleeplessness occurs, discontinue use and consult a doctor. If symptoms do not improve within 7 days or are accompanied by a fever, consult a doctor. This product may cause drowsiness or blurred vision. Patients taking this product should be warned not to engage in activities requiring mental alertness such as operating a motor vehicle or other machinery or to perform hazardous tasks while taking this drug. Sympathomimetic amines should be used with caution in patients with hypertension, ischemic heart disease, diabetes mellitus, increased intraocular pressure, hyperthyroidism, or prostatic hypertrophy. Sympathomimetic amines in overdosage may produce CNS stimulation with convulsions or cardiovascular collapse with accompanying hypotension. Do not exceed recommended dosage.

Antihistamines should be used with considerable caution in pyloroduodenal obstruction; symptomatic prostatic hypertrophy; bladder neck obstruction. Antihistamines may cause excitability, especially in children. At dosages higher than the recommended dose, nervousness, dizziness or sleeplessness may occur. Do not exceed recommended dosage.

Heat prostration can occur with methscopolamine used where the environmental temperature is high. Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy; in this instance, use of methscopolamine would be inappropriate and possibly harmful.

Co-administration of sildenafil citrate and other organic nitrates has been shown to potentiate the hypotension effects of nitrates. Co-administration of Allergy DN PE™ and sildenafil citrate has not been studied. Therefore, the use of sildenafil citrate and Allergy DN PE™ together is not recommended.

PRECAUTIONS

This product contains FD&C Yellow No. 5 (tartrazine) which may cause allergic-type reactions (including bronchial asthma) in certain susceptible persons. Although the overall incidence of FD&C Yellow No. 5 (tartrazine) sensitivity in the general population is low, it is frequently seen in patients who also have aspirin hypersensitivity.

General

Use phenylephrine with caution in patients with hypoxia, acidosis, or a history of arteriosclerosis, bradycardia, partial heart block, hypertension, myocardial disease, thrombosis, or ventricular tachycardia. Antihistamines have an atropine-like action and should be used with caution in patients with a history of bronchial asthma, emphysema, increased intraocular pressure, hyperthyroidism, cardiovascular disease and hypertension.

Use methscopolamine with caution in patients with hiatal hernia associated with reflux esophagitis. Use extreme caution and only when needed in patients with autonomic neuropathy, hepatic or renal disease, ulcerative colitis (especially in the elderly), hyperthyroidism, coronary heart disease, congestive heart failure, and cardiac arrhythmia. Investigate any tachycardia before giving any anticholinergic drugs since they may increase the heart rate. Prolonged use of anticholinergics may decrease or inhibit salivary flow, thus contributing to the development of caries, periodontal disease, oral candidiasis, and discomfort.

Drug Interactions

Monoamine oxidase (MAO) inhibitors (or for 14 days after stopping MAOI therapy) and beta-adrenergic blockers increase the effect of sympathomimetic amines. Sympathomimetic amines may reduce the antihypertensive effects of methyldopa, mecamylamine and reserpine. Concomitant use of antihistamines with alcohol, tricyclic antidepressants, antipsychotics, barbiturates and other CNS depressants may have an additive effect. Concomitant administration with antacids may interfere with the absorption of methscopolamine nitrate.

Information for Patients

Patient consultation should include the following information regarding proper use of this medication:

Caution patients about the signs of potential side effects, especially:

Note: When anticholinergics are given to patients especially children, where the environmental temperature is high there is risk of a rapid increase in body temperature because of suppression of sweat gland activity. Infants, patients with Down's syndrome, and children with spastic paralysis or brain damage may show an increased response to anticholinergics, thus increasing the potential for side effects. Geriatric or debilitated patients may respond to usual doses of anticholinergics with excitement, agitation, drowsiness, or confusion.

Laboratory Tests

The following may be especially important in patient monitoring (other tests may be warranted in some patients, depending on conditions):

Laboratory Test Interactions

Antihistamines may interfere with diagnostic test results for skin tests using allergen extracts. Anticholinergics may interfere with diagnostic test results for gastric acid secretion by antagonizing the effect of pentagastrin and histamine, and for radionucleotide gastric emptying studies by delaying gastric emptying.

Carcinogenesis, Mutagenesis, Impairment of Fertility

Animal studies to assess the long-term carcinogenic and mutagenic potential or the effect on fertility in animals or humans have not been performed.

Pregnancy Category C

Animal reproduction studies have not been conducted with this product. It is also not known whether this product can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. This product should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Labor and Delivery

Use of phenylephrine during labor may cause fetal anoxia and bradycardia by increasing contractility of the uterus and decreasing uterine blood flow.

Nursing Mothers

It is not known whether this combination drug is excreted in human milk. However, phenylephrine HCl administered alone distributes into the breast milk of lactating human females; therefore, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use

The safety and effectiveness in children under 12 years of age have not been established.

Geriatric Use

The elderly (60 years and older) are more likely to experience adverse reactions to sympathomimetics. Overdosage of sympathomimetics in this age group may cause hallucinations, convulsions, CNS depression, and /or death. Demonstrate safe use of a short-acting sympathomimetic amine before use of an extended-action formulation.

ADVERSE REACTIONS

The following adverse reactions have been observed with the use of phenylephrine, chlorpheniramine and methscopolamine: Increased irritability or excitement (especially in children), arrhythmias, palpitations, blood dyscrasias, CNS depression, CNS stimulation, dizziness, drowsiness dryness of mouth, hallucinations, hypotension, hypertension, increased sensitivity of skin to sun, increased sweating, flushing, loss of appetite, paradoxical reaction, restlessness, skin rash, stomach upset or pain, thickening of mucus, tingling in hands or feet, trembling, troubled breathing, unusual tiredness or weakness, nausea or vomiting. Sympathomimetics have been associated with certain untoward reactions including fear, anxiety, nervousness, restlessness, tremor, weakness, pallor, respiratory difficulty, dysuria, insomnia, convulsions, and cardiovascular collapse with accompanying hypotension.

Note: Agitation; confusion; difficult or painful urination; drowsiness; dizziness; and dryness of mouth, nose or throat are more likely to occur in the elderly. Nightmares, unusual excitement, nervousness, restlessness, or irritability are more likely to occur in children and the elderly. When anticholinergics are given to patients, especially children, where the environmental temperature is high, there is risk of a rapid increase in body temperature.

DRUG ABUSE AND DEPENDENCE

Central nervous system stimulants such as phenylephrine have been abused. At high doses, subjects commonly experience an elevation of mood, a sense of increased energy and alertness, and decreased appetite. Some individuals become anxious, irritable and loquacious. In addition to the marked euphoria, the user experiences a sense of markedly enhanced physical strength and mental capacity. With continued use, tolerance develops, the user increases the dose, and toxic signs and symptoms appear. Depression may follow rapid withdrawal.

Stimulants, such as phenylephrine, are banned and tested for by the U.S. Olympic Committee (USOC) and the National Collegiate Athletic Association (NCAA).

OVERDOSAGE AND TREATMENT OF OVERDOSAGE

Overdosage

The treatment of overdosage should provide symptomatic and supportive care. Induction of emesis and gastric lavage may be performed if the patient is alert and seen within early hours after ingestion. Either isotonic or half-isotonic saline may be used for lavage. Administration of an activated charcoal slurry is beneficial after lavage and/or emesis if less than 4 hours have passed since ingestion. Stimulants should not be used, because they may precipitate convulsions. Use of a short-acting barbiturate is recommended if convulsions or marked CNS excitement occur. Since the effects of this product may last up to 12 hours, the patient should be monitored for at least that length of time and treated as necessary. Cardiovascular and renal effects include difficulty in urination, headache, flushing, palpitation, cardiac arrhythmias, hypertension with subsequent hypotension and circulatory collapse. Gastrointestinal effects include dry mouth, anorexia, nausea, vomiting, diarrhea and abdominal cramps.
