Trital SR - Clinical Pharmacology

The mechanism of analgesic action of acetaminophen has not been fully determined. Acetaminophen may act by inhibiting prostaglandin synthesis in the central nervous system (CNS) and, through peripheral action, by blocking pain-impulse generation. The peripheral action may be due to inhibition of the syntheses of prostaglandins or to inhibition of the synthesis or actions of other substances that sensitize pain receptors to mechanical or chemical stimulation.

Chlorpheniramine maleate is an alkylamine-type antihistamine. This group of antihistamines is among the most active histamine antagonists and are generally effective in relatively low doses.

Phenylephrine hydrochloride is primarily a direct acting sympathomimetic amine.

Sympathomimetic amines act on alpha adrenergic receptors in the mucosa of the respiratory tract to produce vasoconstriction, which temporarily reduces the swelling associated with inflammation of the mucous membranes lining the nasal passages. Phenyltoloxamine citrate is an ethanol amine-type compound used as an adjuvant with acetaminophen to mediate the release of bradykinin and prostaglandin, two agents involved in the cause of inflammatory pain.

Indications and Usage for Trital SR

Trital™ SR is indicated for the temporary relief of allergy induced nasal congestion, runny nose, sneezing, headache and associated pain caused from inhalation of airborne antigens and other irritants.

Contraindications

Trital™ SR should not be administered to patients who have previously exhibited hypersensitivity to any of the ingredients Risk-benefit should be considered when any of the following medical problems exist: alcoholism, asthma, bladder-neck obstruction, urinary retention, cardiovascular disease, diabetes mellitus, glaucoma, hepatic function impairment, hypertension, hyperthyroidism, prostatic hypertrophy, psychosis or other psychiatric disorders, renal function impairment, viral hepatitis.

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. If pain or fever persist, if new symptoms occur, or if redness or swelling is present, consult your physician immediately because these could be signs of a serious condition. Do not give this product to children under 12 years of age. Caution should be exercised when used in patients with prostatic hypertrophy, urinary retention, bladder neck obstruction, increased ocular pressure and asthma.

Alcohol Warning

If you consume 3 or more alcoholic drinks every day, ask you doctor whether you should take acetaminophen or other pain relievers/ fever reducers. Acetaminophen may cause liver damage.

Precautions

Information for Patients

Patient consultation should include the following information regarding the proper use of Trital™ SR.

  • Do not exceed recommended dosage.
  • 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.
  • May be taken with food, water, or milk to lessen gastric irritation.
  • Do not drive or operate heavy machinery if drowsiness or dizziness occurs.
  • Concomitant use of alcohol and other central nervous system depressants (hypnotics, sedatives, tranquilizers and anti-anxiety drugs) while taking Trital™ SR may have an additive effect on drowsiness.
  • If a dose is missed, the medication should be taken as soon as possible unless it is almost time for the next dose. Doses should not be doubled.
  • Tablet may be broken in half for ease of swallowing without affecting release of the medication, do not chew or crush before swallowing.
  • Stimulants, such as phenylephrine, are banned and tested for by the U.S. Olympic Committee (USOC) and the National Collegiate Athletic Association (NCAA).

Laboratory Tests

In patients with severe hepatic or renal disease, effects of therapy should be monitored with serial liver and/or renal function tests.

Drug Interactions

Combinations containing any of the following medications, depending on the amount present, may interact with Trital™ SR: CNS depressants/stimulants, antihistamines, anticholinergics, anesthetics, digitalis glycosides, tricyclic antidepressants, diuretics, beta-adrenergic blocking agents, doxapram, MAIO's (or for 14 days after stopping MAOI therapy), ototoxic medications, rauwolfia alkaloids, hepatic enzyme inducers, hepatoxic medications, anticoagulants, NSAID's, aspirin or other salicylates, zidovudine.

Drug/Laboratory Tests Interactions

Acetaminophen may produce false positive tests results for urinary 5-hydroxyindoleacetic acid. Blood glucose determinations may be falsely decreased by acetaminophen when measured by the glucose oxidase/peroxidase method. Antihistamines may inhibit the cutaneous histamine response of skin tests using allergen extracts, thus producing false-negative results. The sedative effects of chlorpheniramine and phenyltoloxamine are additive to the CNS depressant effects of alcohol, hypnotics, sedatives and tranquilizers.

Carcinogenesis, Mutagenesis, Impairment of Fertility

No adequate studies have been conducted in animals or humans to determine whether Trital™ SR has a potential for carcinogenesis, mutagenesis or impairment of fertility.

Pregnancy

Teratogenic Effects

Pregnancy Category C

There are no adequate and well-controlled studies in pregnant women. Trital™ SR should be used during pregnancy only if the potential benefits justify the potential risk to the fetus.

Nursing Mothers

Small amounts of acetaminophen, antihistamines and sympathomimetics are excreted in breast milk. Due to the potential for serious adverse reactions in nursing infants from Trital™ SR, the healthcare provider must decide whether to discontinue the drug during nursing, taking into account the health benefits to the mother.

Pediatric Use

Safety and effectiveness in the pediatric population, under 12, have not been established. Pediatric patients may be more sensitive to the effects of Trital™ SR. Very young children may be more susceptible to the effects, especially the vasopressor effects, of sympathomimetics. In older children taking antihistamines, a paradoxical reaction characterized by hyperexcitability may occur.

Geriatric Use

Geriatric patients may be more sensitive to the effects of Trital™ SR. Confusion, dizziness, sedation, hallucination, hypotension, hyperexcitability, seizures, CNS depression, vasopressor and anticholinergic side effects may be more likely to occur in geriatric patients.

Adverse Reactions

The following adverse effects have been selected on the basis of their potential clinical significance (not necessarily inclusive): allergic reactions, anemia, blood dyscrasias (sore throat and fever, unusual bleeding or bruising, unusual tiredness or weakness), psychotic episodes (mood or mental changes) - usually associated in previous history of psychiatric illness, tightness in chest.

Overdosage

Signs and symptoms

anticholinergic effects (clumsiness or unsteadiness; severe dryness of mouth, nose or throat; flushing or redness of face; shortness of breath or troubled breathing), CNS stimulation (hallucinations, seizures, trouble in sleeping), drowsiness (severe), hypertension, diarrhea, increased sweating, loss of appetite, nausea, vomiting, stomach cramps or pain. Hepatotoxicity - signs and symptoms may occur 2 to 4 days after ingestion (pain or tenderness in the upper abdominal area, swelling of abdominal area).

Recommended Treatment

Recommended treatment of overdose consists of the following:

  • Emptying the stomach via induction of emesis or gastric lavage.
  • For excessive hypertensive effect, an alpha-adrenergic blocker, such as phentolamine, may be administered.
  • Administering activated charcoal. However, activated charcoal may interfere with absorption of oral acetylcysteine.
  • Acetylcysteine is recommended as soon as possible after ingestion of an overdose, without waiting for results of plasma acetaminophen determination or other lab test. Acetylcysteine is most effective if treatment is started within 10 to 12 hours after ingestion of the overdose.
  • Instituting hemodialysis or hemoperfusion to remove acetaminophen from the circulation may be beneficial if acetylcysteine cannot be administered within 24 hours after overdose.
  • Monitoring renal and cardiac function and administering appropriate therapy as required.
  • Instituting supportive therapy, including maintaining fluid and electrolyte balance, correcting hypoglycemia and administering vitamin K1 and fresh frozen plasma or clotting factor concentrate.

Serum acetaminophen levels should be obtained at least 4 hours following overdose. Determinations performed prior to this time are not reliable for assessing potential hepatoxicity.

Hepatic enzymes should be obtained initially, and repeated at 24 hour intervals for at least 96 hours post ingestion.
