Amlodipine/benazepril, sold under the brand name Lotrel among others, is a medication used to treat high blood pressure. It is a combination of amlodipine, a calcium channel blocker and benazepril, an angiotensin converting enzyme inhibitor. It may be used if a single agent is not sufficient. It is taken by mouth.Common side effects include cough, dizziness, and swelling. Serious side effects may include angioedema, myocardial infarction, high blood potassium, liver problems, and low blood pressure. Use in pregnancy is not recommended. Amlodipine works by increasing the size of arteries while benazepril works by decreasing renin-angiotensin-aldosterone system activity.The combination was approved for medical use in the United States in 1995. It is available as a generic medication. In 2019, it was the 213th most commonly prescribed medication in the United States, with more than 2 million prescriptions. Medical uses
It is used to treat high blood pressure. It is not a first line treatment. References

Proliferation of these cells causes replacement of normal bone and marrow with fibrous tissue. The bony trabeculae are abnormally thin and irregular, and often likened to Chinese characters (bony spicules on biopsy).Fibrous dysplasia is not hereditary, and there has never been a case of genetic inheritance from parent to child. Diagnosis
On x-ray, fibrous dysplasia appears as bubbly lytic lesions, or a ground glass appearance. Computerized tomography (CT) or magnetic resonance imaging (MRI) scans may be used to determine how extensively bones are affected. CT can better demonstrate the typical "ground glass" appearance, which is a highly specific radiological finding, while MRI can show cystic areas with fluid contents. A bone scan uses radioactive tracers, which are injected into your bloodstream. The damaged parts of bones take up more of the tracer, which show up more brightly on the scan. A biopsy, which uses a hollow needle to remove a small piece of the affected bone for laboratory analysis, can diagnose fibrous dysplasia definitely. Treatment
Treatment in fibrous dysplasia is mainly palliative, and is focused on managing fractures and preventing deformity. There are no medications capable of altering the disease course. Intravenous bisphosphonates may be helpful for treatment of bone pain, but there is no clear evidence that they strengthen bone lesions or prevent fractures. Surgical techniques that are effective in other disorders, such as bone grafting, curettage, and plates and screws, are frequently ineffective in fibrous dysplasia and should be avoided. Intramedullary rods are generally preferred for management of fractures and deformity in the lower extremities.
