Pharmacology
Feedback for Salicylate Combination
Compare with other drugs.
|
Relieves pain by inhibiting prostaglandin synthesis and release; reduces fever by vasodilation of peripheral vessels. Unlike aspirin, does not inhibit platelet aggregation.
Pharmacokinetics
Absorption
Salicylate is absorbed rapidly and reaches C max in approximately 1 to 2 h after a single dose of a tablet or liquid doseform.
Metabolism
The primary salicylate metabolites are glycine and glucuronide conjugates.
Elimination
The primary route of excretion of salicylate is renal. Serum salicylate concentrations are increased by conditions that decrease glomerular filtration rate or proximal tubular secretion. Salicylate t ½ is approximately 9 to 17 h.
Indications and Usage
Relief of mild-to-moderate pain; treatment of rheumatic fever and rheumatoid arthritis including juvenile arthritis and osteoarthritis; management of fever.
Contraindications
Hypersensitivity to nonacetylated salicylates, NSAIDs or aspirin; advanced chronic renal insufficiency; bleeding disorders; GI bleeding.
Dosage and Administration
Inflammatory ConditionsAdults
PO 1500 mg twice daily or 3000 mg every day.
Elderly PatientsPO 750 mg 3 times daily.
Fever, Mild-to-Moderate PainAdults
PO 1000 to 1500 mg twice daily.
Children under 37 kgPO 50 mg/kg/day in 2 divided doses.
Children over 37 kgPO 2250 mg/day in 2 divided doses. Doses are adjusted based on patient's response, tolerance and serum salicylate concentration.
Storage/Stability
Store in tight, light-resistant container.
Drug Interactions
Carbonic anhydrase inhibitors (eg, acetazolamide)Accumulation of carbonic anhydrase inhibitor and toxicity.
CorticosteroidsDecreased plasma salicylate concentration.
MethotrexateCould cause methotrexate toxicity.
Oral hypoglycemics or insulinCould cause hypoglycemia.
Urinary acidifiersIncreased salicylate serum concentration.
Urinary alkalinizers (eg, chronic antacids)Decreased salicylate serum concentration.
WarfarinEnhanced anticoagulant activity of oral anticoagulants. Creates potential for increased prothrombin time due to protein-binding displacement.
Laboratory Test Interactions
PhenolsulfonphthaleinSalicylates decrease renal excretion.
Thyroid function testsDrug causes increased free T 4 and decreased total T 4 ; thyroid function is not affected.
Urine glucoseDrug causes false-negative results by glucose oxidase method and false-positive results by copper reduction method with moderate to high doses of salicylates.
Urine 5-HIAASalicylates interfere with fluorescent method.
Urine ketonesDrug causes interference with ferric chloride (Gerhardt) method by turning urine a reddish color.
Urine vanillylmandelic acidSalicylates can interfere with determination.
Adverse Reactions
Dermatologic
Hives; rash; angioedema.
EENT
Tinnitus.
GI
Nausea; dyspepsia; gastric ulceration.
Hematologic
Prolonged bleeding time.
Hepatic
Hepatotoxicity.
Metabolic
Uric acid levels elevated by salicylate concentrations less than 10 mg/dL and decreased by levels greater than 10 mg/dL.
Respiratory
Bronchospasm.
Miscellaneous
Anaphylaxis; salicylism may occur with large doses or chronic therapy (symptoms include dizziness, tinnitus, vomiting, diarrhea, confusion, CNS depression, headache, sweating, hyperventilation, and lassitude); fever.
Precautions
MonitorMonitor pain relief and temperature after medication administration. If tinnitus, flushing, tachycardia, hyperventilation, sweating, or thirst occurs, withhold medication. |
Pregnancy
Category C . Do not use during third trimester; could prematurely close ductus arteriosus in the fetus.
Lactation
Excreted in breast milk.
Children
May increase risk of Reye's syndrome; do not use in individuals under 18 yr if chickenpox or flu symptoms are suspected.
Special Risk Patients
Use drug with caution in patients with renal or hepatic dysfunction, peptic ulcer disease, or gastritis.
Aspirin or NSAID hypersensitivity
Nonacetylated salicylates have been tolerated in aspirin-sensitive asthmatic patients; however, cases of cross-sensitivity including bronchospasm have been reported.
Overdosage
Symptoms
Respiratory alkalosis, hyperpnea, tachypnea, nausea, vomiting, hypokalemia, tinnitus, neurologic abnormalities (disorientation, irritability, lethargy, stupor), dehydration, hyperthermia, seizures, coma.
Patient Information
- Advise patient to take medication with food or after meals with full glass of water.
- Emphasize need to avoid alcohol ingestion and use of NSAIDs during therapy (which increase risk of GI irritation/GI bleeding), especially if patient is undergoing long-term therapy.
- Instruct patients with diabetes to monitor blood levels closely during treatment.
- Instruct patient to call health care provider immediately if ringing in ears or persistent GI pain occurs while taking this medication.
