Generics: Ibandronic Acid
Dosage Form: Tablet.
Ibandronic corrosive is shown for the treatment of postmenopausal osteoporosis, to diminish the hazard of fractures. Treatment of Osteoporosis: Osteoporosis may be affirmed by the finding of moo bone mass (T-score <-2.0 SD) and the nearness or history of osteoporotic break, or a moo bone mass (T-score <-2.5 SD) within the nonattendance of recorded pre-existing osteoporotic break.
The pharmacodynamic activity of ibandronic etching is an obstacle to bone resorption. In vivo, the ibandronic sulphate prevents the pulverization of bone due to gonadal inactivation, retinoids, tumors, or neoplasms. In young (rapidly growing) mice, endogenous bone resorption was more impeded, resulting in increased bone mass compared with untreated organisms. Biological models suggest that the ibandronic sorbent can be an extremely potent inhibitor of osteoclast activity. In growing rats, there was indeed no evidence of demineralization at doses greater than 5,000 times the dose required to treat osteoporosis. The high potency and useful advantages of E-banding allow more adaptive dosing regimens and intermittent treatment with long drug-free periods at relatively low doses.
Corrosion Ibandronic can be an extremely potent bisphosphonate with a nitrogen-containing bisphosphonate position, acting on bone tissue and specifically blocking osteoclast activity. The specific action of ibandronic corrosion on bone tissue is based on this compound’s great preference for hydroxyapatite, which dictates the mineral structure of bone. Ibandronic corrosion reduces bone resorption without a synergistic effect on bone alignment. In postmenopausal women, it reduces bone turnover to premenopausal levels, resulting in a marked increase in bone mass. Day after day, or intermittent tissue erosion leads to decreased bone resorption, as evidenced by decreased serum and urine biochemical markers of bone remodeling, enlarged and decreased BMD. fracture frequency.
Advised by doctor.
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.
Route of administration: Orally.
It is likely that calcium supplements, antacids and some oral medications containing multivalent cations (such as aluminium, magnesium, iron) are likely to interfere with the absorption of Ibandronic Acid. Therefore, patients must wait 60 minutes after taking Ibandronic Acid before taking other oral medications. Pharmacokinetic interaction studies in postmenopausal women have demonstrated the absence of any interaction potential with tamoxifen or hormone replacement therapy (estrogen). No interaction was observed when co-administered with melphalan/prednisolone in patients with multiple myeloma. In healthy male volunteers and postmenopausal women, i.v. ranitidine caused an increase in ibandronic acid bioavailability of about 20 %, probably as a result of reduced gastric acidity. However, since this increase is within the normal range of the bioavailability of ibandronic acid, no dosage adjustment is required when Ibandronic Acid is administered with H2-antagonists or other drugs which increase gastric pH.
In relation to disposition, no drug interactions of clinical significance are considered likely, since ibandronic acid does not inhibit the major human hepatic P450 isoenzymes and has been shown not to induce the hepatic cytochrome P450 system in rats. Furthermore, plasma protein binding is low at therapeutic concentrations and ibandronic acid is therefore unlikely to displace other drugs. Ibandronic acid is eliminated by renal excretion only and does not undergo any biotransformation. The secretory pathway appears not to include known acidic or basic transport systems involved in the excretion of other drugs. In a one-year study in postmenopausal women with osteoporosis (BM16549). the incidence of upper gastrointestinal events in patients concomitantly taking aspirin or NSAIDs was similar in patients taking Ibandronic Acid 2.5 mg daily or 150mg once monthly. Of over 1500 patients enrolled in study BM 16549 comparing monthly with daily dosing regimens of ibandronic acid, 14% of patients used histamine (H2) blockers or proton pump inhibitors. Among these patients, the incidence of upper gastrointestinal events in the patients treated with Ibandronic Acid 150 mg once monthly was similar to that in patients treated with Ibandronic Acid 2.5 mg daily.
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.
The main side effects of ibandronic acid are dyspepsia, nausea, diarrhea, abdominal pain, muscle aches, headaches, dizziness.
Pregnancy & 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.
Precautions & Warnings:
Hypocalcemia and other disturbances of bone and mineral metabolism should be effectively treated before starting Ibandronic Acid therapy. Adequate intake of calcium and vitamin D is important in all patients. Orally administered bisphosphonates may cause local irritation of the upper gastrointestinal mucosa. Because of these possible irritant effects and a potential for worsening of the underlying disease, caution should be used when Ibandronic Acid is given to patients with active upper gastrointestinal problems (e.g. known Barrett’s esophagus, dysphagia, other esophageal diseases, gastritis, duodenitis or ulcers). Adverse experiences such as esophagitis, esophageal ulcers and esophageal erosions, in some cases severe and requiring hospitalization, rarely with bleeding or followed by esophageal stricture or perforation, have been reported in patients receiving treatment with oral bisphosphonates. The risk of severe esophageal adverse experiences appears to be greater in patients who do not comply with the dosing instruction and/or who continue to take oral bisphosphonates after developing symptoms suggestive of esophageal irritation. Patients should pay particular attention and be able to comply with the dosing instructions.
Physicians should be alert to any signs or symptoms signaling a possible esophageal reaction and patients should be instructed to discontinue Ibandronic Acid and seek medical attention if they develop dysphagia, odynophagia, retrosternal pain or new or worsening heartburn. While no increased risk was observed in controlled clinical trials there have been post-marketing reports of gastric and duodenal ulcers with oral bisphosphonate use, some severe and with complications. Since NSAIDs and bisphosphonates are both associated with gastrointestinal irritation, caution should be taken during concomitant medication with Ibandronic Acid. Osteonecrosis of the jaw (ONJ) has been reported in patients treated with bisphosphonates. Most cases have been in cancer patients undergoing dental procedures, but some have occurred in patients with postmenopausal osteoporosis or other diagnoses. Known risk factors for osteonecrosis of the jaw include a diagnosis of cancer, concomitant therapies (e.g., chemotherapy, radiotherapy, corticosteroids), and co-morbid disorders (e.g., anemia, coagulopathy, infection, pre-existing dental disease). Most reported cases have been in patients treated with bisphosphonates intravenously but some have been in patients treated orally. For patients who develop osteonecrosis of the jaw while on bisphosphonate therapy, dental surgery may exacerbate the condition. For patients requiring dental procedures, there are no data available to suggest whether discontinuation of bisphosphonate treatment reduces the risk of ONJ. Clinical judgment of the treating physician should guide the management plan of each patient based on individual benefit-risk assessment.
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.
Store in a cool & dry place, protected from light. Keep all medicines out of reach of children.
