Ostoimp
Ostoimp Uses, Dosage, Side Effects, Food Interaction and all others data.
Ostoimp inhibits osteoclast-mediated bone-resorption. Like all bisphosphonates, it is chemically related to inorganic pyrophosphate, the endogenous regulator of bone turnover. But while pyrophosphate inhibits both osteoclastic bone resorption and the mineralization of the bone newly formed by osteoblasts, alendronate specifically inhibits bone resorption without any effect on mineralization at pharmacologically achievable doses. Its inhibition of bone-resorption is dose-dependent and approximately 1,000 times stronger than the equimolar effect of the first bisphosphonate drug, etidronate. Under therapy, normal bone tissue develops, and alendronate is deposited in the bone-matrix in a pharmacologically inactive form. For optimal action, enough calcium and vitamin D are needed in the body in order to promote normal bone development. Hypocalcemia should, therefore, be corrected before starting therapy.
Ostoimp tablets have a very low oral bioavialability. After administration it distributes into soft tissue and bone or is excreted in the urine. Ostoimp does not undergo metabolism.

Uses
Ostoimp is used for the-
- Treatment and prevention of osteoporosis in post-menopausal women
- Treatment of osteoporosis, Ostoimp increases bone mass and reduces the incidence of fractures, including those of the hip and spine (vertebral compression fractures)
- Prevention of osteoporosis, Ostoimp may be considered in postmenopausal women who are at risk of developing osteoporosis and for whom the desired clinical outcome is to maintain bone mass and to reduce the risk of future fracture
- Treatment toincrease bone mass in men with osteoporosis
- Treatment of glucocorticoid-induced osteoporosis in men and women receiving glucocorticoids in a daily dosage equivalent to 7.5 mg or greater of prednisone and who have low bone mineral density. Patients treated with glucocorticoids should receive adequate amounts of calcium and vitamin D
- Treatment of Paget’s disease of bone in men and women
Ostoimp is also used to associated treatment for these conditions: Osteogenesis Imperfecta (OI), Osteoporosis, Osteoporosis caused by glucocorticoid, Paget’s Disease
How Ostoimp works
Ostoimp binds to bone hydroxyapatite. Bone resorption causes local acidification, releasing alendronic acid which is that taken into osteoclasts by fluid-phase endocytosis. Endocytic vesicles are acidified, releasing alendronic acid to the cytosol of osteoclasts where they induce apoptosis. Inhibition of osteoclasts results in decreased bone resorption which is shown through decreased urinary calcium, deoxypyridinoline and cross-linked N-telopeptidases of type I collagen.
Dosage
Ostoimp dosage
Treatment of osteoporosis in post-menopausal women: The recommended dose is one Ostoimp 70 mg once weekly or 10 mg once daily.
Treatment to increase bone mass in men with osteoporosis:The recommended dose is one Ostoimp tablet 10 mg once daily. Alternatively, one Ostoimp 70 mg once weekly may be considered.
Prevention of osteoporosis in post-menopausal women: The recommended dose is 35 mg once weekly or 5 mg once daily. The safety of treatment and prevention of osteoporosis with Ostoimp has been studied for up to 7 years.
Use for elderly patients: No dosage adjustment is required for elderly patients. Because in clinical study there was no evidence of age related differences in the efficacy or safety profiles of Ostoimp.
Treatment of glucocorticoid-induced osteoporosis in men and women: The recommended dose is 5 mg once daily, except for post-menopausal women not receiving oestrogen, for whom the recommended dose is 10 mg once daily.
Paget’s disease of bone in men and women: The recommended treatment regimen is 40 mg once a day for six months.
Side Effects
The commonest symptomatic side effects are constipation, diarrhoea, oesophageal ulcer, flatulence, dysphagia, musculoskeletal pain, headache, rarely rash, erythema, transient decrease in serum calcium and phosphate, nausea, vomiting, peptic ulceration, hypersensitivity reactions including urticaria and angio-oedema.
Toxicity
In clinical studies, ≥3% of patients experience abdominal pain, acid regurgitation, constipation, diarrhea, dyspepsia, musculoskeletal pain, and nausea.
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 induced. Patients may experience hypocalcemia, hypophosphatemia, and upper gastrointestinal events..
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 dose.
Excretion in breast milk, and therefore safety in lactation, is unknown.
Ostoimp has been studied for use in pediatric patients. The oral bioavailability is similar to that in adult patients, but an increase in the portion of patients experiencing vomiting.
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 study.
Ostoimp is not recommended for patients with creatinine clearance Label.
Interaction
The incidence of upper gastrointestinal side effects are increased with the concomitant use of non-steroidal anti-inflammatory agents and aspirin. Absorption of Alendronate is reduced in the presence of antacids and calcium supplements.
Food Interaction
- Administer vitamin supplements. Patients may require supplemental vitamin D.
- Avoid multivalent ions. Calcium, antacids, and divalent ions may interfere with the absorption of this medication.
- Take before a meal. Take 30-60 minutes before breakfast.
- Take with a full glass of water.
Volume of Distribution
28L.
Elimination Route
Mean oral bioavailability of alendronic acid in women is 0.64% and in men is 0.59%. Bioavailability of alendronic acid decreases by up to 40% if it is taken within an hour of a meal.
Half Life
Due to alendronic acid being incorporated into the skeleton, the terminal half life is estimated to be over 10 years.
Clearance
71mL/min.
Elimination Route
Administration of radiolabeled alendronic acid results in 50% recovery in urine within 72 hours. No alendronic acid is recovered in the feces. Men excrete less alendronic acid than women, though race and advanced age do not affect elimination.
Pregnancy & Breastfeeding use
Ostoimp should not be given to pregnant women or nursing mother.
Contraindication
Hypocalcaemia; Renal impairment; Vitamin D deficiency; Active gastrointestinal problem such as dysphagia, oesophago-duodenitis or ulcer; and Hypersensitivity to any components of the tablet.
Special Warning
Children: Not recommended.

FAQ
What is Ostoimp used for?
Ostoimp is a bisphosphonate medication used to treat osteoporosis and Paget's disease of bone. Taking Ostoimp can help if you have, or are at risk of developing, osteoporosis. This is a condition that causes your bones to get weaker and be more likely to break.
How safe is Ostoimp?
This evidence shows Ostoimp to be safe and effective; it should be considered the nonhormonal therapy of choice for treating osteoporosis in postmenopausal women at risk for hip and vertebral fractures.
How does Ostoimp work?
Ostoimp works by slowing down the production of the cells that wear down bone (osteoclasts). This helps to improve bone strength and makes the bone less fragile.
What are the common side effects of Ostoimp?
Some people may have serious side effects when taking Ostoimp. These include heartburn (or heartburn that gets worse), problems or pain when swallowing, or chest pain. These may be signs of ulcers in your food pipe (oesophagus). If this happens, stop taking Ostoimp and speak to a doctor.
Is Ostoimp safe during pregnancy?
Ostoimp should not be used during pregnancy.
Is Ostoimp safe during breastfeeding?

Can I drink alcohol with Ostoimp?
Yes, you can drink alcohol while taking Ostoimp. However, drinking a lot of alcohol affects the strength of your bones and can increase your risk of breaks (fractures).
