'''Oral administration'''
* An identical dosage regimen may be followed by administering aminocaproic acid tablets or aminocaproic acid oral solution as follows:
:* For the treatment of acute bleeding syndromes due to elevated [[fibrinolytic]] activity, it is suggested that 5 aminocaproic acid 1000 mg tablets or 10 aminocaproic acid 500 mg tablets (5 g) or 20 milliliter of aminocaproic acid oral Solution (5 g) be administered during the first hour of treatment, followed by a continuing rate of 1 aminocaproic acid 1000 mg tablet or 2 aminocaproic acid 500 mg tablets (1 g) or 5 milliliter of aminocaproic acid oral solution (1.25 g) per hour. This method of treatment would ordinarily be continued for about 8 hours or until the bleeding situation has been controlled.
'''IV administration'''
* Aminocaproic acid injection is administered by infusion, utilizing the usual compatible intravenous vehicles (e.g., Sterile Water for Injection, [[Sodium Chloride]] Injection 0.9%, [[Dextrose]] Injection 5% or [[Ringer’s]] Injection).  Although Sterile Water for Injection is compatible for intravenous injection, the resultant solution is hypo-osmolar.  Rapid injection of aminocaproic acid injection undiluted into a vein is not recommended.

The intravenous and oral LD50 of aminocaproic acid were 3.0 and 12.0 g/kg, respectively, in the mouse and 3.2 and 16.4 g/kg, respectively, in the rat. An intravenous infusion dose of 2.3 g/kg was lethal in the dog. On intravenous administration, tonic-clonic [[convulsions]] were observed in dogs and mice.


====Compatible====
No treatment for overdosage is known, although evidence exists that aminocaproic acid is removed by [[hemodialysis]] and may be removed by [[peritoneal dialysis]]. Pharmacokinetic studies have shown that total body clearance of aminocaproic acid is markedly decreased in patients with severe [[renal failure]].

Overview

Aminocaproic acid (injection) is a hemostatic that is FDA approved for the treatment of acute bleeding syndromes due to elevated fibrinolytic activity. Common adverse reactions include abdominal pain, nausea, vomiting, diarrhea, headache dizziness, confusion, hallucinations, blurred vision, tinnitus.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Acute Bleeding Syndromes due to Elevated Fibrinolytic Activity
Dosing Information
  • Aminocaproic acid injection is administered by infusion, utilizing the usual compatible intravenous vehicles (e.g., Sterile Water for Injection, Sodium Chloride Injection 0.9%, Dextrose Injection 5% or Ringer’s Injection). Although Sterile Water for Injection is compatible for intravenous injection, the resultant solution is hypo-osmolar. Rapid injection of aminocaproic acid injection undiluted into a vein is not recommended.
  • For the treatment of acute bleeding syndromes due to elevated fibrinolytic activity, it is suggested that 16 to 20 mL (4 to 5 g) of aminocaproic acid injection in 250 mL of diluent be administered by infusion during the first hour of treatment, followed by a continuing infusion at the rate of 4 mL (1 g) per hour in 50 mL of diluent. This method of treatment would ordinarily be continued for about 8 hours or until the bleeding situation has been controlled. * Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Pediatric Indications and Dosage

FDA-Labeled Indications and Dosage (Pediatric)

There is limited information regarding Aminocaproic acid (injection) FDA-Labeled Indications and Dosage (Pediatric) in the drug label.

Off-Label Use and Dosage (Pediatric)

Guideline-Supported Use

There is limited information regarding Off-Label Guideline-Supported Use of Aminocaproic acid in pediatric patients.

Non–Guideline-Supported Use

Post-Surgery Intraocular Hemorrhage
  • Dosing Information
  • 5 g 60 minutes before surgery, then 5 g q6h.[4]

Contraindications

Aminocaproic acid should not be used when there is evidence of an active intravascular clotting process.

When there is uncertainty as to whether the cause of bleeding is primary fibrinolysis or disseminated intravascular coagulation (DIC), this distinction must be made before administering aminocaproic acid.

The following tests can be applied to differentiate the two conditions:

  • Platelet count is usually decreased in DIC but normal in primary fibrinolysis.
  • Protamine paracoagulation test is positive in DIC; a precipitate forms when protamine sulfate is dropped into citrated plasma. The test is negative in the presence of primary fibrinolysis.
  • The euglobulin clot Iysis test is abnormal in primary fibrinolysis but normal in DIC.

AMICAR must not be used in the presence of DIC without concomitant heparin.

Warnings

In patients with upper urinary tract bleeding, aminocaproic acid administration has been known to cause intrarenal obstruction in the form of glomerular capillary thrombosis or clots in the renal pelvis and ureters. For this reason, aminocaproic acid should not be used in hematuria of upper urinary tract origin, unless the possible benefits outweigh the risk.

Subendocardial hemorrhages have been observed in dogs given intravenous infusions of 0.2 times the maximum human therapeutic dose of aminocaproic acid and in monkeys given 8 times the maximum human therapeutic dose of aminocaproic acid.

Fatty degeneration of the myocardium has been reported in dogs given intravenous doses of aminocaproic acid at 0.8 to 3.3 times the maximum human therapeutic dose and in monkeys given intravenous doses of aminocaproic acid at 6 times the maximum human therapeutic dose.

Rarely, skeletal muscle weakness with necrosis of muscle fibers has been reported following prolonged administration. Clinical presentation may range from mild myalgias with weakness and fatigue to a severe proximal myopathy with rhabdomyolysis, myoglobinuria, and acute renal failure. Muscle enzymes, especially creatine phosphokinase (CPK) are elevated. CPK levels should be monitored in patients on long-term therapy. Aminocaproic acid administration should be stopped if a rise in CPK is noted. Resolution follows discontinuation of aminocaproic acid; however, the syndrome may recur if aminocaproic acid is restarted.

The possibility of cardiac muscle damage should also be considered when skeletal myopathy occurs. One case of cardiac and hepatic lesions observed in man has been reported. The patient received 2 g of aminocaproic acid every 6 hours for a total dose of 26 g. Death was due to continued cerebrovascular hemorrhage. Necrotic changes in the heart and liver were noted at autopsy.

Precautions

General

Aminocaproic acid inhibits both the action of plasminogen activators and to a lesser degree, plasmin activity. The drug should not be administered without a definite diagnosis and/or laboratory finding indicative of hyperfibrinolysis (hyperplasminemia). Inhibition of fibrinolysis by aminocaproic acid may theoretically result in clotting or thrombosis. However, there is no definite evidence that administration of aminocaproic acid has been responsible for the few reported cases of intravascular clotting which followed this treatment. Rather, it appears that such intravascular clotting was most likely due to the patient's preexisting clinical condition, e.g., the presence of DIC. It has been postulated that extravascular clots formed in vivo may not undergo spontaneous Iysis as do normal clots.

Reports have appeared in the literature of an increased incidence of certain neurological deficits such as hydrocephalus, cerebral ischemia, or cerebral vasospasm associated with the use of antifibrinolytic agents in the treatment of subarachnoid hemorrhage (SAH). All of these events have also been described as part of the natural course of SAH, or as a consequence of diagnostic procedures such as angiography. Drug relatedness remains unclear.

Aminocaproic acid should not be administered with Factor IX Complex concentrates or Anti-Inhibitor Coagulant concentrates, as the risk of thrombosis may be increased.

Laboratory Tests

The use of aminocaproic acid should be accompanied by tests designed to determine the amount of fibrinolysis present. There are presently available: (a) general tests such as those for the determination of the Iysis of a clot of blood or plasma; and (b) more specific tests for the study of various phases of the fibrinolytic mechanisms. These latter tests include both semiquantitative and quantitative techniques for the determination of profibrinolysin, fibrinolysin, and antifibrinolysin.

Laboratory Test Interactions
  • Prolongation of the template bleeding time has been reported during continuous intravenous infusion of aminocaproic acid at dosages exceeding 24 g/day.
  • Platelet function studies in these patients have not demonstrated any significant platelet dysfunction. However, in vitro studies have shown that at high concentrations (7.4 mMol/L or 0.97 mg/mL and greater) aminocaproic acid inhibits ADP and collagen-induced platelet aggregation, the release of ATP and serotonin, and the binding of fibrinogen to the platelets in a concentration-response manner.
  • Following a 10 g bolus of aminocaproic acid, transient peak plasma concentrations of 4.6 mMol/L or 0.60 mg/mL have been obtained. The concentration of aminocaproic acid necessary to maintain inhibition of fibrinolysis is 0.99 mMol/L or 0.13 mg/mL. Administration of a 5 g bolus followed by 1 to 1.25 g/hr should achieve and sustain plasma levels of 0.13 mg/mL.
  • Concentrations which have been obtained in vivo clinically in patients with normal renal function are considerably lower than the in vitro concentrations found to induce abnormalities in platelet function tests.

It is also not known whether aminocaproic acid can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Aminocaproic acid should be given to a pregnant woman only if clearly needed.
Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Aminocaproic acid (injection) in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Aminocaproic acid (injection) during labor and delivery.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when AMICAR is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatic Use

There is no FDA guidance on the use of Aminocaproic acid (injection) in geriatric settings.

Gender

There is no FDA guidance on the use of Aminocaproic acid (injection) with respect to specific gender populations.

Race

There is no FDA guidance on the use of Aminocaproic acid (injection) with respect to specific racial populations.

Renal Impairment

Higher plasma concentrations of aminocaproic acid may occur in patients with severe renal failure.

Hepatic Impairment

There is no FDA guidance on the use of Aminocaproic acid (injection) in patients with hepatic impairment.

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Aminocaproic acid (injection) in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Aminocaproic acid (injection) in patients who are immunocompromised.

Administration and Monitoring

Administration

Intravenous

Monitoring

There is limited information regarding Aminocaproic acid (injection) Monitoring in the drug label.

IV Compatibility

Aminocaproic acid injection is administered by infusion, utilizing the usual compatible intravenous vehicles (e.g., Sterile Water for Injection, Sodium Chloride Injection 0.9%, Dextrose Injection 5% or Ringer’s Injection).

Overdosage

A few cases of acute overdosage with aminocaproic acid administered intravenously have been reported. The effects have ranged from no reaction to transient hypotension to severe acute renal failure leading to death. One patient with a history of brain tumor and seizures experienced seizures after receiving an 8 gram bolus injection of aminocaproic acid. The single dose of aminocaproic acid causing symptoms of overdosage or considered to be life-threatening is unknown. Patients have tolerated doses as high as 100 grams while acute renal failure has been reported following a dose of 12 grams.

The intravenous and oral LD50 of aminocaproic acid were 3.0 and 12.0 g/kg, respectively, in the mouse and 3.2 and 16.4 g/kg, respectively, in the rat. An intravenous infusion dose of 2.3 g/kg was lethal in the dog. On intravenous administration, tonic-clonic convulsions were observed in dogs and mice.

No treatment for overdosage is known, although evidence exists that aminocaproic acid is removed by hemodialysis and may be removed by peritoneal dialysis. Pharmacokinetic studies have shown that total body clearance of aminocaproic acid is markedly decreased in patients with severe renal failure.

Mechanism of Action

The fibrinolysis-inhibitory effects of aminocaproic acid appear to be exerted principally via inhibition of plasminogen activators and to a lesser degree through antiplasmin activity.

Structure

Aminocaproic acid is 6-aminohexanoic acid, which acts as an inhibitor of fibrinolysis.

Its chemical structure is:

Aminocaproic acid is soluble in water, acid, and alkaline solutions; it is sparingly soluble in methanol and practically insoluble in chloroform.

Aminocaproic acid oral solution for oral administration, contains 0.25 g/mL of aminocaproic acid with methylparaben 0.20%, propylparaben 0.05%, edetate disodium 0.30% as preservatives and the following inactive ingredients: sodium saccharin, sorbitol solution, citric acid anhydrous, natural and artificial raspberry flavor and an artificial bitterness modifier.

Each AMICAR (aminocaproic acid) Tablet, for oral administration contains 500 mg or 1000 mg of aminocaproic acid and the following inactive ingredients: povidone, crospovidone, stearic acid, and magnesium stearate.

Aminocaproic Acid is soluble in water, acid and alkaline solutions; it is sparingly soluble in methanol and practically insoluble in chloroform. Aminocaproic Acid Injection, USP, for intravenous administration, is a sterile pyrogen-free solution containing 250 mg/mL of aminocaproic acid with Benzyl Alcohol 0.9%, as a preservative, and Water for Injection q.s. The pH is adjusted to approximately 6.8 with Hydrochloric Acid and/or Sodium Hydroxide.

Pharmacodynamics

There is limited information regarding Pharmacodynamics of aminocaproic acid in the drug label.

Pharmacokinetics

In adults, oral absorption appears to be a zero-order process with an absorption rate of 5.2 g/hr. The mean lag time in absorption is 10 minutes.

After a single oral dose of 5 g, absorption was complete (F=1). Mean ± SD peak plasma concentrations (164 ± 28 mcg/mL) were reached within 1.2 ± 0.45 hours.

After oral administration, the apparent volume of distribution was estimated to be 23.1 ± 6.6 L (mean ± SD). Correspondingly, the volume of distribution after intravenous administration has been reported to be 30.0 ± 8.2 L. After prolonged administration, aminocaproic acid has been found to distribute throughout extravascular and intravascular compartments of the body, penetrating human red blood cells as well as other tissue cells.

Renal excretion is the primary route of elimination. Sixty-five percent of the dose is recovered in the urine as unchanged drug and 11% of the dose appears as the metabolite adipic acid. Renal clearance (116 mL/min) approximates endogenous creatinine clearance. The total body clearance is 169 mL/min. The terminal elimination half-life for aminocaproic acid is approximately 2 hours.

Nonclinical Toxicology

Long-term studies in animals to evaluate the carcinogenic potential of aminocaproic acid and studies to evaluate its mutagenic potential have not been conducted. Dietary administration of an equivalent of the maximum human therapeutic dose of aminocaproic acid to rats of both sexes impaired fertility as evidenced by decreased implantations, litter sizes and number of pups born.
