CLINICAL PHARMACOLOGY:Phenobarbital is a barbiturate, nonselective central nervous system depressant which is primarily used as a sedative hypnotic and also as an anticonvulsant in subhypnotic doses. Atropine Sulfate, Hyoscyamine Sulfate and Scopolamine Hydrobromide are belladonna alkaloids classified as anticholinergic, antimuscarinic drugs and act to inhibit muscarinic actions of acetycholine at postganglionic parasympathetic neuron effector sites. These drugs are also used as antispasmodics due to their anticholinergic action and produce the effect in the body of reduced muscle spasms in the digestive or urinary tract, and reduced fluid secretions from certain glands or organs. This drug combination provides peripheral anticholinergic/antispasmodic action and mild sedation.
INDICATIONS AND USAGE:FDA has classified the following indications as "possibly" effective: For use as adjunctive therapy in the treatment of irritable bowel syndrome (irritable colon, spastic colon, mucous colitis) and acute enterocolitis. May also be useful as adjunctive therapy in the treatment of duodenal ulcer.
IT HAS NOT BEEN SHOWN CONCLUSIVELY WHETHER ANTICHOLINERGIC/ANTISPASMODIC DRUGS AID IN THE HEALING OF A DUODENAL ULCER, DECREASE THE RATE OF RECURRENCES OR PREVENT COMPLICATIONS.
CONTRAINDICATIONS:Quadrapax Elixir is contraindicated in patients with known hypersensitivity to any of the ingredients. Phenobarbital is contraindicated in patients with acute intermittent porphyria and in those patients in which phenobarbital produces restlessness and/or excitement.
It is also contraindicated in patients with glaucoma, obstructive uropathy; paralytic ileus; myasthenia gravis; intestinal atony; unstable cardiovascular status in acute hemorrhage; hiatal hernia associated with reflux esophagitis; obstructive disease of the gastrointestinal tract; or severe ulcerative colitis.
WARNINGS:Heat prostration can occur with belladonna alkaloids in high temperatures.
Diarrhea may be an early symptom of incomplete intestinal obstruction, especially in patients with ileostomy or colostomy. In this instance, treatment with this drug could be harmful.
Quadrapax Elixir may produce drowsiness and blurred vision. The patient should be warned about engaging in hazardous work or activities requiring mental alertness, such as operating a motor vehicle or other machinery. Phenobarbital may decrease the effect of anticoagulants, and larger doses of the anticoagulant may be needed for optimal effect. When phenobarbital is discontinued, the dose of the anticoagulant may have to be decreased. Phenobarbital may be habit forming and should not be administered to patients who are susceptible to addiction or to those with a history of physical and/or psychological drug dependence.
Barbiturates should be used with caution in patients with hepatic dysfunction.
Use with caution in patients with prostatic hypertrophy, autonomic neuropathy, hepatic or renal disease, hyperthyroidism, coronary heart disease, congestive heart failure, cardiac arrhythmias, tachycardia, and hypertension.
Belladonna alkaloids may produce a delay in gastric emptying (antral stasis) which would complicate the management of gastric ulcer. Do not rely on the use of the drug in the presence of complication of biliary tract disease. Theoretically, with overdosage, a curare-like action may occur.

CARCINOGENESIS, MUTAGENESIS, IMPAIRMENT OF FERTILITY:
Long-term studies in animals have not been performed to evaluate carcinogenic potential.
PREGNANCY TERATOGENIC EFFECTS:
Pregnancy Category D.
Quadrapax Elixir can cause fetal harm when administered to a pregnant woman. Retrospective case-controlled studies have suggested a connection between the maternal consumption of phenobarbital and higher than expected incidence of fetal abnormalities. Following oral administration, phenobarbital readily crosses the placental barrier and is distributed throughout fetal tissues with highest concentrations found in the placenta, fetal liver, and brain. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.
Reports of infants suffering from long-term phenobarbital exposure in utero included the acute withdrawal syndrome of seizures and hyperirritability from birth to a delayed onset of up to 14 days.
LABOR AND DELIVERY:
Administration of Quadrapax Elixir to the mother during labor may result in respiratory depression in the newborn. Premature infants are particularly susceptible to the depressant effects.
Caution should be exercised when Quadrapax Elixir is administered to a nursing woman. The active ingredients contained in this drug product are known to be excreted in human milk.
SPECIAL PATIENT POPULATION:
Dosage should be reduces in the debilitated because these patients may be more sensitive to phenobarbital. Dosage should be reduced for patients with impaired renal function or hepatic disease.
Use Quadrapax Elixir with caution in children as they may be more susceptible to the effects of this product especially infants, children with Down's syndrome, spastic paralysis or brain damage.
Sedating drugs may cause confusion and over-sedation in the elderly; elderly patients generally should be started on low doses of Quadrapax Elixir and observed closely. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.
ADVERSE REACTIONS:Adverse reactions associated with anticholinergics and/or anticonvulsants are: dry mouth; tachycardia; urinary hesitancy and retention; palpitation; blurred vision; prolonged pupil dilation; cycloplegia; increased ocular tension; loss of taste sense; headache; nervousness; drowsiness; weakness; dizziness; insomnia; nausea; vomiting; severe allergic reaction or drug idiosyncrasies, including anaphylaxis, hives and/or other dermal manifestations; decreased sweating; impotence; suppression of lactation; constipation; bloated feeling and musculoskeletal pain. Elderly patients may react with symptoms of excitement, agitation and drowsiness to even small doses of the drug. Phenobarbital may produce excitement in some patients, rather than a sedative effect. In patients habituated to barbiturates, abrupt withdrawal may produce delirium or convulsions.
DRUG ABUSE AND DEPENDENCE:This product is subject to the provisions of the Controlled Substance Act and has been placed in Schedule IV. Phenobarbital may be habit-forming. Tolerance, psychological dependence, and physical dependence may occur following prolonged use.
Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.
OverdosageAn overdose of Quadrapax Elixir is a potentially lethal overdose situation. Call your doctor or a Poison Control Center immediately if an overdose is suspected.
SIGNS AND SYMPTOMS:
Characteristics of phenobarbital overdose include decreased consciousness leading to coma, bradycardia, bradypnea, hypothermia and hypotention. Overdose may also lead to pulmonary edema and acute renal failure as result of shock. Other symptoms of an overdose with this product include headache, nausea, vomiting, tachycardia, severe or persistent blurred vision, dilated pupils, hot and dry skin, dizziness or disorientation, severe dryness of the mouth, difficulty in swallowing, and CNS stimulation.
Treatment of overdose is supportive, and consists mainly in the maintenance of airway patency through endotracheal intubation and mechanical ventilation, correction of bradycardia and hypotention with intravenous fluids and vasopressors, if necessary, and removal of as much drug as possible from the body. Depending on how much time has elapsed since ingestion of the drug, this may be accomplished through gastric lavage or use of activated charcoal.
DOSAGE AND ADMINISTRATION:The dosage of Quadrapax Elixir should be adjusted to the needs of the individual patient to assure symptomatic control with a minimum of adverse effects.
Adults: One or two teaspoonfuls of elixir three to four times a day according to conditions and severity of symptoms.
Pediatric patients: may be dosed every 4 to 6 hours.
