Carbetapentane  Citrate Structure

Pseudoephedrine Hydrochloride (Benzenemethanol, α-[1-(methylamino)ethyl]-, [S-(R*,R*)-, hydrochloride) is the
hydrochloride of pseudoephedrine, a naturally occurring dextrorotatory stereoisomer of ephedrine. Its structure
is as follows:

Pseudoephedrine Hydrochloride Structure

CLINICAL PHARMACOLOGY

Antitussive and decongestant actions.

Carbetapentane citrate is a centrally acting non-narcotic antitussive. Carbetapentane citrate has atropine-like and local
anesthetic actions, as well as temporarily controls and suppresses the cough reflex by selective depression of the
medullary cough center. It has no significant analgesic or sedative properties, does not depress respiration or predispose
to addiction with usual doses.

Pseudoephedrine hydrochloride is an oral sympathomimetic amine that acts as a decongestant to respiratory tract
mucous membranes. While its vasoconstrictor action is similar to that of ephedrine, pseudoephedrine has less
pressor effect in normotensive adults. Serum half-life for pseudoephedrine is 6 to 8 hours. Acidic urine is associated
with faster elimination of the drug. About one-half of the administered drug is excreted in the urine.

INDICATIONS AND USAGE

CorzallTM is indicated for the symptomatic relief of the cough, coryza and nasal congestion associated with the common
cold, sinusitis, allergic rhinitis and other upper respiratory tract conditions. Appropriate therapy should be provided for the
primary disease.

CONTRAINDICATIONS

Patients with hypersensitivity or idiosyncrasy to any of its ingredients. Sympathomimetic amines are contraindicated
in patients with severe hypertension, severe coronary heart disease and patients on monoamine oxidase (MAO) inhibitor
therapy.

WARNINGS

Sympathomimetic amines should be used judiciously and sparingly in patients with hypertension, diabetes, ischemic
heart disease, hyperthyroidism, increased intraocular pressure, or prostatic hypertrophy. (See CONTRAINDICATIONS).
Sympathomimetic amines may produce CNS stimulation with convulsions or cardiovascular collapse with accompanying
hypotension. The elderly (60 years and older) are more likely to exhibit adverse reactions.

A persistent cough may be a sign of a serious condition. If cough persists for more than one week or tends to recur, or is
accompanied by fever, rash, or persistent headache, patient re-evaluation should be considered.

PRECAUTIONS

General: There are studies which demonstrate that carbetapentane has antitussive activity which may suppress or modify
cough. Before prescribing medication to suppress or modify cough, identify and provide therapy for the underlying cause of
the cough and take caution that modification of cough does not increase the risk of clinical or physiologic complications.

Use with caution in patients with hypertension, heart disease, asthma, hyperthyroidism, increased intraocular pressure,
diabetes mellitus, and prostatic hypertrophy.

Information for patients:

Avoid alcohol and other CNS depressants while taking this product. Patients sensitive to sympathomimetics may note
mild CNS stimulation.

Drug Interactions:

Carbetapentane citrate should not be used in patients receiving MAO inhibitors, including 14 days after stopping the MAOI
drug. The use of Carbetapentane citrate may result in additive CNS depressant effects when coadministered with alcohol,
antihistamines, psychotropics or other drugs that produce CNS depression.
Sympathomimetics may reduce the hypotensive effects of guanethidine, mecamylamine, methyldopa, reserpine and
veratrum alkaloids. Concurrent use of tricyclic antidepressants may antagonize the effects of pseudoephedrine. Use of
other vasopressor drugs during halothane anethesia may cause serious cardiac arrhythmias.

Pregnancy Category C:

Animal reproduction studies have not been conducted with this product. It is not known whether this product can cause fetal
harm when administered to a pregnant woman or affect reproductive capacity. Give to pregnant women only if clearly needed.

Nursing Mothers:

It is not known if the drugs in this product are excreted in human milk. Since many drugs may be excreted into human milk
and because of the potential for serious side effects in the nursing infant, this product should only be given to nursing mothers
if clearly needed.

Pediatric use:

Safety and effectiveness in pediatric patients below the age of six have not been established. Product not intended for
administration for children 6 years of age and under.

Geriatric use:

The elderly (60 years and older) are more likely to have adverse reactions to sympathomimetics. Overdosage of
sympathomimetics in this age group may cause hallucinations, convulsions, CNS depression and death.

ADVERSE REACTIONS

Adverse effects associated with Carbetapentane citrate are rare, but nausea and/or other gastrointestinal disturbances
sometimes occur.

Sympathomimetic Amines: Convulsions, CNS stimulation, cardiac arrhythmia, respiratory difficulties, increased heart
rate or blood pressure, hallucinations, tremors, nervousness, insomnia, pallor and dysuria.

OVERDOSAGE

The signs, symptoms and treatment described below are those of pseudoephedrine and carbetapentane.

Symptoms: Should sympathomimetic symptoms predominate, central effects includes restlessness, dizziness, tremor,
hyperactive reflexes, talkativeness, irritability, and insomnia. Cardiovascular and renal effects include difficulty in micturition,
headache, flushing, palpitation, cardiac arrhythmia, hypertension with subsequent hypotension and circulatory collapse.
Gastrointestinal effects include dry mouth, metallic taste, anorexia, nausea, vomiting, diarrhea and abdominal cramps.

Treatment:
a) Evacuate stomach as condition warrants. Activated charcoal may be useful.
b) Maintain a non-stimulating environment.
c) Monitor cardiovascular status.
d) Do not give stimulants.
e) Reduce fever with sponging.
f) Use sedatives or anticonvulsants to control CNS excitation, and convulsions.
g) Physostigmine may reverse anti-cholinergic symptoms.
h) Ammonium Chloride may acidify the urine to increase urinary excretion of pseudoephedrine.
I) Further care is symptomatic and supportive.

DOSAGE AND ADMINISTRATION*

Adults and Children 12 years of age and older:
1-2 teaspoonfuls (5-10 mL) every 4-6 hours, not to exceed 12 teaspoonfuls in a 24 hour period.
