Ibandronic Acid
Indications
Ibandronic acid is indicated for the treatment of postmenopausal osteoporosis, to reduce the risk of fractures. Treatment of Osteoporosis: Osteoporosis may be confirmed by the finding of low bone mass (T-score <-2.0 SD) and the presence or history of osteoporotic fracture, or a low bone mass (T-score <-2.5 SD) in the absence of documented pre-existing osteoporotic fracture.
Pharmacology
The pharmacodynamic action of ibandronic acid is inhibition of bone resorption. In vivo, ibandronic acid prevents experimentally induced bone destruction caused by cessation of gonadal function, retinoids, tumors or tumor extracts. In young (fast growing) rats, the endogenous bone resorption is also inhibited, leading to increased bone mass compared with untreated animals. Animal models confirm that ibandronic acid is a highly potent inhibitor of osteoclastic activity. In growing rats, there was no evidence of impaired mineralization even at doses greater than 5,000 times the dose required for osteoporosis treatment. The high potency and therapeutic margin of ibandronic acid allows for more flexible dosing regimens and intermittent treatment with long drug-free intervals at comparatively low doses. Ibandronic acid is a highly potent bisphosphonate belonging to the nitrogen-containing group of bisphosphonates, which act on bone tissue and specifically inhibit osteoclast activity, It does not interfere with osteoclast recruitment. The selective action of ibandronic acid on bone tissue is based on the high affinity of this compound for hydroxyapatite, which represents the mineral matrix of the bone. Ibandronic acid reduces bone resorption, with no direct effect on bone formation. In postmenopausal women, it reduces the elevated rate of bone turnover towards premenopausal levels, leading to a progressive net gain in bone mass. Daily or intermittent administration of ibandronic acid results in reduced bone resorption as reflected in reduced levels of serum and urinary biochemical markers of bone turnover, increased BMD and a decreased incidence of fractures.
Dosage Administration
The recommended dose of Ibandronic acid for treatment is one 150 mg film-coated tablet once a month. The tablet should preferably be taken on the same date each month. Ibandronic acid should be taken 60 minutes before the first food or drink (other than water) of the day or any other oral medication or supplementation (including calcium): Tablets should be swallowed whole with a full glass of plain water (180 to 240 ml) while the patient is sitting or standing in an upright position. Patients should not lie down for 60 minutes after taking Ibandronic acid. Plain water is the only drink that should be taken with Ibandronic acid. Please note that some mineral waters may have a higher concentration of calcium and therefore should not be used. Patients should not chew or suck the tablet because of a potential for oropharyngeal ulceration. Patients should receive supplemental calcium or vitamin D if dietary intake is inadequate. In case a once-monthly dose is missed, patients should be instructed to take one Ibandronic Acid 150 mg tablet the morning after the tablet is remembered unless the time to the next scheduled dose is within 7 days. Patients should then return to taking their dose once a month on their originally scheduled date. If the next scheduled dose is within 7 days, patients should wait until their next dose and then continue taking one tablet once a month as originally scheduled. Patients should not take two 150 mg tablets within the same week.
Contraindications
Ibandronic Acid is contraindicated in patients with known hypersensitivity to ibandronic acid or to any of the excipients. Ibandronic Acid is contraindicated in patients with uncorrected hypocalcemia. As with all bisphosphonates indicated in the treatment of osteoporosis, pre-existing hypocalcemia needs to be corrected before initiating therapy with Ibandronic Acid. As with several bisphosphonates, Ibandronic Acid is contraindicated in patients with abnormalities of the esophagus which delay esophageal emptying such as stricture or achalasia. Ibandronic Acid is contraindicated in patients who are unable to stand or sit upright for at least 60 minutes.
Side Effects
Patients with renal impairment: No dosage adjustment is necessary for patients with mild or moderate renal impairment where creatinine clearance is ≥30 ml/min. Below 30 ml/min creatinine clearance, the decision to administer Ibandronic Acid should be based on an individual risk-benefit assessment. Patients with hepatic impairment: No dosage adjustment is necessary. Elderly: No dosage adjustment is necessary. Children: Safety and efficacy have not been established in patients less than 18 years old.
Pregnancy And Lactation
Pregnancy: Ibandronic Acid should not be used during pregnancy. There was no evidence for a direct fetal toxic or teratogenic effect of ibandronic acid in daily orally treated rats and rabbits and there were no adverse effects on the development in F1 offspring in rats. Adverse effects of ibandronic acid in reproductive toxicity studies in the rat were those observed with bisphosphonates as a class. They include a decreased number of implantation sites, interference with natural delivery (dystocia), and an increase in visceral variations (renal pelvis ureter syndrome). Specific studies for the monthly regimen have not been performed. There is no clinical experience with Ibandronic Acid in pregnant women. Nursing Mothers: Ibandronic Acid should not be used during lactation. In lactating rats treated with 0.08 mg/kg/day IV. ibandronic acid, the highest concentration of ibandronic acid in breast milk was 8.1 ng/ml and was seen in the first 2 hours after i.v. administration. After 24 hours, the concentration in milk and plasma was similar, and corresponded to about 5 % of the concentration measured after 2 hours.
Therapeutic
No specific information is available on the treatment of overdosage with ibandronic acid. However, oral overdosage may result in upper gastrointestinal adverse events, such as upset stomach, heartburn, esophagitis, gastritis, or ulcer. Milk or antacids should be given to bind ibandronic acid. Owing to the risk of esophageal irritation, vomiting should not be induced and the patient should remain fully upright.
