Pharmacology

Indication

Alendronic acid is indicated for the treatment and prevention of osteoporosis in men and postmenopausal women, treatment of glucocorticoid-induced osteoporosis, and Paget's disease of boneLabel1,2. However, alendronic acid is not indicated for use in pediatric populations or patients with a creatinine clearance <35mL/minLabel.

Pharmacodynamics

Alendronic acid tablets have a very low oral bioavialabilityLabel2. After administration it distributes into soft tissue and bone or is excreted in the urineLabel. Alendronic acid does not undergo metabolismLabel.

Mechanism of action

Alendronic acid binds to bone hydroxyapatiteLabel. Bone resorption causes local acidification, releasing alendronic acid which is that taken into osteoclasts by fluid-phase endocytosis1. Endocytic vesicles are acidified, releasing alendronic acid to the cytosol of osteoclasts where they induce apoptosis1. Inhibition of osteoclasts results in decreased bone resorption which is shown through decreased urinary calcium, deoxypyridinoline and cross-linked N-telopeptidases of type I collagenLabel.

Absorption

Mean oral bioavailability of alendronic acid in women is 0.64% and in men is 0.59%Label2. Bioavailability of alendronic acid decreases by up to 40% if it is taken within an hour of a mealLabel.

Volume of distribution

28LLabel.

Protein binding

78%Label. Studies in rats show that plasma protein binding increases with decreasing alendronic acid plasma concentration3 and increasing pH4.

Metabolism

Urinary excretion is the sole method of elimination of alendronic acid and no metabolites are detected upon urine collection2.

Route of elimination

Administration of radiolabeled alendronic acid results in 50% recovery in urine within 72 hoursLabel4. No alendronic acid is recovered in the fecesLabel2,3. Men excrete less alendronic acid than women, though race and advanced age do not affect eliminationLabel.

Half-life

Due to alendronic acid being incorporated into the skeleton, the terminal half life is estimated to be over 10 yearsLabel.

Clearance

71mL/minLabel.

Toxicity

In clinical studies, ≥3% of patients experience abdominal pain, acid regurgitation, constipation, diarrhea, dyspepsia, musculoskeletal pain, and nauseaLabel.

No information for treatment of overdose is available, however patients should be given milk or antacids to bind alendronic acid and vomiting should not be inducedLabel. Patients may experience hypocalcemia, hypophosphatemia, and upper gastrointestinal events.Label.

There are currently no studies for safety and efficacy in pregnancy, though studies in pregnant rats show fetal and maternal complications at 4 times the clinical dose and pregnant rabbits do not show complications at as high as 10 times the clincal doseLabel.

Excretion in breast milk, and therefore safety in lactation, is unknownLabel.

Alendronic acid has been studied for use in pediatric patientsLabel. The oral bioavailability is similar to that in adult patients, but an increase in the portion of patients experiencing vomitingLabel.

There is no significant difference in efficacy or safety of alendronic acid in geriatric populations, though there is potential for even greater sensitivity in patients at a further advanced age than those in the studyLabel.

Alendronic acid is not recommended for patients with creatinine clearance <35mL/min, but no dosage adjustment is necessary in hepatic impairmentLabel.
