FDA Label

5 Pharmacology and Biochemistry

5.1 Pharmacology

Etidronic acid is a first generation bisphosphonate that inhibits the action of osteoclasts, preventing bone resporption. It has a wide therapeutic index as overdoses are not associated with severe toxicity and a long duration of action as it slowly releases from the bone. Patients should be counselled regarding the risk of upper gastrointestinal adverse reactions.

5.2 MeSH Pharmacological Classification

Bone Density Conservation Agents

Agents that inhibit BONE RESORPTION and/or favor BONE MINERALIZATION and BONE REGENERATION. They are used to heal BONE FRACTURES and to treat METABOLIC BONE DISEASES such as OSTEOPOROSIS. (See all compounds classified as Bone Density Conservation Agents.)

5.3 FDA Pharmacological Classification

5.3.1 Active Moiety

ETIDRONIC ACID

5.3.2 FDA UNII

M2F465ROXU

5.3.3 Pharmacological Classes

Chemical Structure [CS] - Diphosphonates

5.4 ATC Code

M - Musculo-skeletal system

M05 - Drugs for treatment of bone diseases

M05B - Drugs affecting bone structure and mineralization

M05BA - Bisphosphonates

M05BA01 - Etidronic acid

5.5 Absorption, Distribution and Excretion

Absorption

Etidronic acid has an oral bioavailability of 1-10%. Further data regarding pharmacokinetics of etidronic acid are not readily available.

Route of Elimination

Absorbed etidronic acid is eliminated in the urine, while the unabsorbed drug is eliminated in the feces.

Volume of Distribution

Etidronic acid has a volume of distribution of 0.3-1.3L/kg.

Clearance

Etidronic acid has a renal clearance of 0.09L/kg/h.

THE DISTRIBUTION OF TECHNETIUM-99M HEDP IN NORMAL HUMAN ORGANS WAS MEASURED.

GROSSMAN LW ET AL; MEASUREMENTS OF THE DISTRIBUTION OF TECHNETIUM-99M SULFUR COLLOID AND TECHNETIUM-99M HEDP IN NORMAL HUMANS; MED PHYS 10(1) 79 (1983)

THE BONE-SEEKING AGENT (99M)TC-SN-1-HYDROXYETHYLIDENE-1,1-DIPHOSPHONIC ACID UNEXPECTEDLY BINDS TO PARTICLES OF HUMAN ARTICULAR CARTILAGE AS WELL AS CORTICAL BONE IN VITRO. MECHANISMS ADDITIONAL TO THE SIMPLE IONIC ATTRACTION BETWEEN THE PHOSPHONATE GROUPS OF HEDP & METAL CATIONS SUCH AS CA2+ ARE RESPONSIBLE FOR THE UPTAKE OF (99M)TC-HEDP BY BODY TISSUES.

THE AFFINITY CONSTANT WHICH CHARACTERIZES THE BINDING OF (99)TC-HYDROXYETHYLENE DIPHOSPHONATE (TC-HEDP) WITH HUMAN SERUM ALBUMIN WAS 7.8X10+4. A SINGLE SLOPE WAS OBTAINED.

DEWANJEE MK ET AL; AFFINITY CONSTANTS OF TECHNETIUM-99-PERTECHNETATE AND TECHNETIUM-CHELATES WITH HUMAN SERUM ALBUMIN; RADIOPHARM 2 (PROC INT SYMP, 2ND) 435 (1979)

5.6 Metabolism/Metabolites

Etidronic acid is not metabolized _in vivo_

5.7 Biological Half-Life

The half life of etidronate is approximately 1-6 hours.

5.8 Mechanism of Action

Bisphosphonates are taken into the bone where they bind to hydroxyapatite. Bone resorption by osteoclasts causes local acidification, releasing the bisphosphonate, which is taken into the osteoclast by fluid-phase endocytosis. Endocytic vesicles become acidified, releasing bisphosphonates into the cytosol of osteoclasts where they act. Osteoclasts mediate resorption of bone. When osteoclasts bind to bone they form podosomes, ring structures of F-actin. Disruption of the podosomes causes osteoclasts to detach from bones, preventing bone resorption. First generation bisphosphonates closely mimic the structure of pyrophosphate, which can be incorporated into ATP anologues that cannot be hydrolyzed, disrupting all ATP mediated actions of osteoclasts.

MALE RATS WERE INJECTED WITH VEHICLE (CONTROL GROUP), 0.4 OR 4.0 MG/KG/DAY OF ETHANE-1-HYDROXY-1,1-DIPHOSPHONATE (EHDP). AFTER 6 DAYS OF EHDP TREATMENT ALL RATS RECEIVED 6 SC INJECTIONS OF (3)H-THYMIDINE AT 8 HR INTERVALS. AFTER 6 DAYS OF EHDP PRE-TREATMENT THE MULTIPLE LABELING INDEX OF OSTEOPROGENITOR CELLS WAS REDUCED WITH 4.0 MG/KG/DAY DOSE OF EHDP. EHDP CAUSED INCR IN RATE OF INCORP & ACCUM OF (3)H-THYMIDINE NUCLEI IN OSTEOCLASTS. EHDP CAUSES AN ACCELERATED RATE OF OSTEOCLAST PRODN FROM PRECURSOR CELLS IN SPITE OF ITS ABILITY TO SLOW BONE RESORPTION.
