Zolasta 4mg Injection 10 ml belongs to the class of medicines called 'bisphosphonates' used to treat osteoporosis (weak and brittle bones) caused by menopause or long-term steroid use. Zolasta 4mg Injection 10 ml also treats Paget’s bone and high calcium levels caused by cancer. Osteoporosis is a bone disease that weakens and thins bones by decreasing bone density, common in post-menopausal women.  As the density of bones decreases, they weaken and are more likely to break. 

Zolasta 4mg Injection 10 ml contains Zoledronic acid that works by binding to the bone tightly and preventing the removal of calcium by osteoclasts (a type of bone cell that destroys bone tissue). This prevents osteoclasts from breaking down the bone and keeps the bones strong and minimizes the risk of bones breaking.

A doctor or nurse will administer Zolasta 4mg Injection 10 ml. In some cases, you may experience headache, fever, nausea, dizziness, vomiting, back pain, diarrhea, pain in the muscles, joints, or bones, swelling, or pain at the infusion site. Most of these side effects of Zolasta 4mg Injection 10 ml do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.

Zolasta 4mg Injection 10 ml is not recommended for children below 18 years as the safety and effectiveness were not established. Avoid taking Zolasta 4mg Injection 10 ml if you have hypocalcemia (low calcium levels in the blood) and severe kidney problems. Drive only if you are alert as Zolasta 4mg Injection 10 ml may cause dizziness. Zolasta 4mg Injection 10 ml may cause osteonecrosis of the jaw (ONJ) in some patients.

Zolasta 4mg Injection 10 ml contains Zoledronic acid used to treat postmenopausal osteoporosis, Paget’s disease, and hypercalcemia of malignancy (bone cancer in which excess of calcium exits). Zolasta 4mg Injection 10 ml binds to the bone tightly and prevents calcium removal by osteoclasts (a type of bone cell that destroy bone tissue). This prevents osteoclasts from breaking down the bone, strengthening bones, and minimizing the risk of bones breaking. Also, Zolasta 4mg Injection 10 ml may reduce calcium levels in the blood by preventing calcium reabsorption from bones to the blood. Thus, it helps in treating high calcium levels in the blood caused by cancer.

Osteoporosis: It is a bone disease that weakens and thins bones by decreasing bone density.  As the density of bones decreases, they weaken and are more likely to break. Post-menopausal women are more likely to develop osteoporosis than men because, at menopause, women’s ovaries stop producing estrogen (a female hormone) essential to keeping bones healthy. Following menopause, bone loss occurs, making bones weak and more likely to break. Also, long-term use of steroids may affect bone strength and cause osteoporosis in both men and women. Signs and symptoms include back pain caused by a fractured or collapsed vertebra, loss of height over time, a stooped posture, and a bone that breaks much more easily than expected.

Paget’s disease: In Paget’s disease, bone remodeling (removal of old bone and replacement with new bone material) is too quick, and new bone is formed in a disordered manner making it weaker than normal. If left untreated, the bone may become deformed, painful, and broken.

Hypercalcemia in cancer: In some cancers like breast cancer, lung cancer, or blood cancer, there is too much calcium level in the bloodstream. A patient suffering from a high level of calcium might include nausea, vomiting, constipation, headache, and loss of appetite.
