Full Prescribing Info
Contents
Aspirin.
Action
Low-dose antithrombotic agent.
Aspirin appears to be a highly effective antithrombotic agent that is worth administering prophylactically under medical supervision. Senior patients especially should benefit, considering the ubiquitousness of thrombotic cardiovascular and cerebrovascular disease among the age group. 80 mg/day can be safely prescribed and is likely to keep patients functioning to a more advanced age that might otherwise be the case.
Indications/Uses
Aspilets: Secondary prevention of cerebrovascular events in patients with transient ischemic attacks (TIA) or minor stroke; reinfarction in patients with previous myocardial infarction; restenosis of coronary bypass graft; thrombosis of the arteriovenous shunts in patients undergoing hemodialysis.
Primary prevention of pregnancy-induced hypertension; preeclampsia and intrauterine growth retardation, particularly in pregnant women with preexisting chronic hypertension; autoimmune disorders eg, systemic lupus erythematosus, positive anticardiolipin antibody test, history of recurring toxemia in successive pregnancies, hypertension developing before the 20th week of gestation.
Aspilets-EC: For the prevention of cardiovascular disease: Encourage aspirin use in men (age 45 to 79 years old) and women (age 55 to 79 years old) when potential benefit (i.e., prevention of myocardial infarction in men and prevention of ischemic stroke in women) outweighs potential harm of gastrointestinal hemorrhage. (See Table 1.)

For primary prevention of thromboembolic disorders and cardiovascular events: Ischemic stroke; Transient ischemic attack (TIA); Acute myocardial infarction (MI); Prevention of recurrent MI; Unstable angina pectoris; Chronic stable angina pectoris.
For secondary prevention of cardiovascular disease in persons with diabetes mellitus especially in the following subgroups: History of myocardial infarction, vascular bypass procedure, stroke or transient ischemic attack, and angina.
Persons with additional risk factors: hypertension, smoking, dyslipidemia, and family history of cardiovascular disease.
Revascularization procedures: For patients who have undergone revascularization procedures such as coronary artery bypass graft (CABG), percutaneous transluminal coronary angioplasty (PTCA), and carotid endarterectomy when there is a pre-existing condition for which aspirin is already indicated.
Pregnancy-induced hypertension: For primary prevention of pregnancy-induced hypertension, preeclampsia and intrauterine growth retardation particularly in pregnant women with pre-existing chronic hypertension, auto-immune disorders like systemic lupus erythematosus (SLE), positive cardiolipin antibody test, history of recurring toxemia in successive pregnancies, and hypotension developing before the 20th week of gestation.
Dosage/Direction for Use
Aspilets: 1 tab once daily, preferably after meals or as prescribed by the physician.
High-Risk Pregnancy: For pregnant women at risk of developing toxemia of pregnancy, start Aspilets therapy after the 1st trimester and discontinue at the 37th week of gestation.
Aspilets-EC: General Dosing Recommendations: Take each dose of aspirin with a full glass of water unless patient is fluid restricted. The tablet must be swallowed whole with a glass of water. Do not chew, crush, or bite the enteric coated tablet since this may cause inappropriate release and absorption of the drug. (See Table 2.)

Overdosage
In salicylate overdosage resulting from acute ingestion of aspirin, little or no toxicity generally occurs in individuals ingesting less than 150 mg/kg, mild to moderate toxicity in those ingesting 150 to 300 mg/kg, severe toxicity in those ingesting 300 to 500 mg, and potentially lethal toxicity in those ingesting greater than 500 mg/kg. A single lethal dose of aspirin in adults is not known with certainty but death may be expected at 30 g. The principal toxic effects of salicylate overdosage are extension of pharmacologic actions and include local gastrointestinal irritation, direct central nervous system stimulation of respiration, severe acid-base and electrolyte disturbances and are complicated by hyperthermia and dehydration. Respiratory alkalosis occurs early while hyperventilation is present, but is quickly followed by metabolic acidosis. Treatment consists primarily of supporting vital functions, increasing salicylate elimination, and correcting the acid-base disturbance. Gastric emptying and/or lavage is recommended as soon as possible after ingestion, even if the patient has vomited spontaneously. After lavage and/or emesis, administration of activated charcoal (as a slurry), is beneficial, if less than 3 hours have passed since ingestion. Charcoal adsorption should not be employed prior to emesis and lavage. Severity of aspirin intoxication is determined by measuring the blood salicylate level. Acid-base status should be closely followed with serial blood gas and serum pH measurements. Fluid and electrolyte balance should be maintained. Hemodialysis and peritoneal dialysis may be performed to reduce the body drug content. Dialysis is usually required in patients with renal insufficiency or in cases of life-threatening intoxication.
Contraindications
Aspilets-EC: Known hypersensitivity to aspirin.
Patients with asthma, rhinitis, and nasal polyps. Aspirin may cause severe urticaria, angioedema, or bronchospasm.
Avoid use in children or teenagers for viral infections, with or without fever, because of the risk of Reye's syndrome with concomitant use of aspirin in certain viral illnesses.
Warnings
Gastrointestinal Bleeding Warning: This product contains an NSAID, which may cause severe gastrointestinal bleeding. The chance is higher if the patient is age 60 years or older; has had gastrointestinal ulcers or bleeding problems; takes an anticoagulant or steroid medicine; takes other medicines containing prescription or nonprescription NSAIDs (ibuprofen, naproxen, or others); takes more or for a longer time than prescribed.
Alcohol Warning: Patients who consume three or more alcoholic drinks every day should be counseled about the bleeding risks involved with chronic, heavy alcohol use while taking aspirin.
Coagulation Abnormalities: Aspirin can inhibit platelet function leading to an increase in bleeding time. Avoid its use in patients with inherited (hemophilia) or acquired (liver disease or vitamin K deficiency) bleeding disorders.
General: Do not use in patients with severe renal failure (glomerular filtration rate >10 mL/minute) and severe hepatic insufficiency.
Avoid aspirin use one week prior to and during labor, delivery, and any surgical procedure because it can result in excessive blood loss.
Use In Pregnancy & Lactation
Pregnancy: Pregnant women should only take aspirin if clearly needed. Avoid use during the third trimester of pregnancy because of aspirin's known effect on the fetal cardiovascular system (i.e., closure of the ductus arteriosus).
Lactation: Breastfeeding mothers should avoid using aspirin because salicylate is excreted in breast milk. Use of high doses may lead to rashes, platelet abnormalities, and bleeding in breastfed infants.
Adverse Reactions
Body as a Whole: Fever, hypothermia, thirst.
Cardiovascular: Dysrhythmias, hypotension, tachycardia.
Fluid and Electrolyte: Dehydration, hyperkalemia, metabolic acidosis, respiratory alkalosis.
Gastrointestinal: Dyspepsia, gastrointestinal bleeding, ulceration and perforation, nausea, vomiting, transient elevations of hepatic enzymes, hepatitis, Reye's Syndrome, pancreatitis.
Hematologic: Prolongation of prothrombin time, disseminated intravascular coagulation, coagulopathy, thrombocytopenia.
Hypersensitivity: Acute anaphylaxis, angioedema, asthma, bronchospasm, laryngeal edema, urticaria.
Metabolism: Hypoglycemia (in children), hyperglycemia.
Musculoskeletal: Rhabdomyolysis.
Nervous System: Agitation, cerebral edema, coma, confusion, dizziness, headache, subdural or intracranial hemorrhage, lethargy, seizures.
Reproductive: Prolonged pregnancy and labor, stillbirths, lower birth weight infants, antepartum and postpartum bleeding.
Respiratory: Hyperpnea, pulmonary edema, tachypnea.
Special Senses: Hearing loss, tinnitus. Patients with high frequency hearing loss may have difficulty perceiving tinnitus. In these patients, tinnitus cannot be used as a clinical indicator of salicylism.
Urogenital: Interstitial nephritis, papillary necrosis, proteinuria, renal insufficiency and failure.
Drug Interactions
Angiotensin-converting enzyme (ACE) inhibitors: Hyponatremic and hypotensive effects of ACE inhibitors may be diminished.
Acetazolamide: Increased serum acetazolamide concentrations and toxicity due to competition at the renal tubule for secretion.
Anticoagulant therapy (Heparin, Warfarin): Increased risk of bleeding because of drug-drug interactions and the effect on platelets.
Anticonvulsants: Salicylate can displace protein-bound phenytoin and valproic acid, leading to decreased total concentration of phenytoin and increased serum valproic acid levels.
Beta-blockers: Diminished hypotensive effects of beta-blockers due to inhibition of renal prostaglandins, leading to decreased renal blood flow, and salt and fluid retention.
Diuretics: Diminished effectiveness of diuretics in patients with underlying renal or cardiovascular disease due to inhibition of renal prostaglandins, leading to decreased renal blood flow, and salt and fluid retention.
Methotrexate: Salicylate may inhibit renal clearance of methotrexate, leading to bone marrow toxicity, especially in the elderly or renally impaired.
NSAIDs: Increased bleeding or may lead to decreased renal function.
Oral hypoglycemics: Moderate doses of aspirin may increase the effectiveness of oral hypoglycemic drugs, leading to hypoglycemia.
Uricosuric agents (Probenecid, Sulfinpyrazone): Salicylates antagonize the uricosuric action of these agents.
