Tiludronic Acid
Tiludronic acid (INN; also known as tiludronate) is a bisphosphonate used for treatment of Paget's disease of bone (osteitis deformans) in human medicine. It has the tradename Skelid. In veterinary medicine, tiludronic acid is used to treat navicular disease and bone spavin in horses. Its tradenames are Tildren and Equidronate. It is approved for treatment of navicular disease and distal tarsal osteoarthritis in Europe, and was approved for treatment of navicular disease in the United States in 2014. Mechanism of action Tiludronate is a non-nitrogenous bisphosphonate that inhibits osteoclasts, the primary cell responsible for the breakdown of bone required for bone remodeling. Non-nitrogenous bisphosphonates are metabolized by osteoclasts to compounds that then replace a portion of the adenosine triphosphate (ATP) molecule, making it non-functional. These non-functional molecules then competitively inhibit ATP in the cell, reducing cell energy and leading to apoptosis. Decreased ...

Nephropathy
Kidney disease, or renal disease, technically referred to as nephropathy, is damage to or disease of a kidney. Nephritis is an inflammatory kidney disease and has several types according to the location of the inflammation. Inflammation can be diagnosed by blood tests. Nephrosis is non-inflammatory kidney disease. Nephritis and nephrosis can give rise to nephritic syndrome and nephrotic syndrome respectively. Kidney disease usually causes a loss of kidney function to some degree and can result in kidney failure, the complete loss of kidney function. Kidney failure is known as the end-stage of kidney disease, where dialysis or a kidney transplant is the only treatment option. Chronic kidney disease is defined as prolonged kidney abnormalities (functional and/or structural in nature) that last for more than three months. Acute kidney disease is now termed acute kidney injury and is marked by the sudden reduction in kidney function over seven days. In 2007, about one in eigh ...

Hyperkalemic Periodic Paralysis (equine)
Hyperkalemic periodic paralysis (HYPP, HyperKPP) is a genetic disorder that occurs in horses. It is also known as Impressive syndrome, after an index case in a horse named Impressive. It is an inherited autosomal dominant disorder that affects sodium channels in muscle cells and the ability to regulate potassium levels in the blood. It is characterized by muscle hyperexcitability or weakness which, exacerbated by potassium, heat or cold, can lead to uncontrolled shaking followed by paralysis. The mutation which causes this disorder is dominant on SCN4A with linkage to the sodium channel expressed in muscle. The mutation causes single amino acid changes in parts of the channel which are important for inactivation. In the presence of high potassium levels, including those induced by diet, sodium channels fail to inactivate properly. Equine hyperkalemic periodic paralysis occurs in 1 in 50 Quarter Horses and can be traced to a single ancestor, a stallion named Impressive. Sym ...

Tachycardia
Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. In general, a resting heart rate over 100 beats per minute is accepted as tachycardia in adults. Heart rates above the resting rate may be normal (such as with exercise) or abnormal (such as with electrical problems within the heart). Complications Tachycardia can lead to fainting. When the rate of blood flow becomes too rapid, or fast blood flow passes on damaged endothelium, it increases the friction within vessels resulting in turbulence and other disturbances. According to the Virchow's triad, this is one of the three conditions that can lead to thrombosis (i.e., blood clots within vessels). Causes Some causes of tachycardia include: * Adrenergic storm * Anaemia * Anxiety * Atrial fibrillation * Atrial flutter * Atrial tachycardia * Atrioventricular reentrant tachycardia * AV nodal reentrant tachycardia * Brugada syndrome * Circulatory shock and its various causes ( obstr ...

Horse Colic
Colic in horses is defined as abdominal pain, but it is a clinical symptom rather than a diagnosis. The term colic can encompass all forms of gastrointestinal conditions which cause pain as well as other causes of abdominal pain not involving the gastrointestinal tract. The most common forms of colic are gastrointestinal in nature and are most often related to colonic disturbance. There are a variety of different causes of colic, some of which can prove fatal without surgical intervention. Colic surgery is usually an expensive procedure as it is major abdominal surgery, often with intensive aftercare. Among domesticated horses, colic is the leading cause of premature death. The incidence of colic in the general horse population has been estimated between 4 and 10 percent over the course of the average lifespan. Clinical signs of colic generally require treatment by a veterinarian. The conditions that cause colic can become life-threatening in a short period of time. Pathophysiolog ...

Limb Perfusion
Limb perfusion is a medical technique that is used to deliver drugs locally directly to a site of interest. It is commonly used in human medicine for administration of anticancer drugs directly to an arm or leg. It is also used in veterinary medicine to deliver drugs to a site of infection or injury, as well as for the treatment of cancer in dogs. In both cases, a tourniquet is used to reduce blood flow out of the area that is being treated. Use in human medicine Isolated limb perfusion was first introduced into the clinic by American surgeons from New Orleans in the mid-1950s. The main purpose of the isolated limb perfusion technique is to deliver a very high dose of chemotherapy, at elevated temperature, to tumour sites without causing overwhelming systemic damage. (Unfortunately, while these approaches can be useful against solitary or limited metastases, they are - by definition - not systemic and therefore do not treat distributed metastases or micrometastases). The flow of bloo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zoledronic Acid
Zoledronic acid, also known as zoledronate and sold under the brand name Zometa by Novartis among others, is a medication used to treat a number of bone diseases. These include osteoporosis, high blood calcium due to cancer, bone breakdown due to cancer, Paget's disease of bone and Duchenne muscular dystrophy (DMD). It is given by injection into a vein. Common side effects include fever, joint pain, high blood pressure, diarrhea, and feeling tired. Serious side effects may include kidney problems, low blood calcium, and osteonecrosis of the jaw. Use during pregnancy may result in harm to the baby. It is in the bisphosphonate family of medications. It works by blocking the activity of osteoclast cells and thus decreases the breakdown of bone.

Ibandronic Acid
Ibandronic acid is a bisphosphonate medication used in the prevention and treatment of osteoporosis and metastasis-associated skeletal fractures in people with cancer. It may also be used to treat hypercalcemia (elevated blood calcium levels). It is typically formulated as its sodium salt ibandronate sodium. It was patented in 1986 by Boehringer Mannheim and approved for medical use in 1996. Medical uses Ibandronate is indicated for the treatment and prevention of osteoporosis in post-menopausal women. In May 2003, the U.S. Food and Drug Administration (FDA) approved Ibandronate as a daily treatment for post-menopausal osteoporosis. The basis for this approval was a three-year, randomized, double-blind, placebo-controlled trial women with post-menopausal osteoporosis. Every participant also received daily oral doses of calcium and 400IUs nternational unitsof vitamin D. At the study's conclusion, both doses significantly reduced the occurrence risk of new vertebral fractures ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pamidronic Acid
Pamidronic acid or pamidronate disodium or APD (marketed as Aredia among others), is a nitrogen-containing bisphosphonate used to prevent osteoporosis. It was patented in 1971 and approved for medical use in 1987. Medical uses It is used to prevent bone loss, and treat osteoporosis. It is also used to strengthen bone in Paget's disease, to prevent bone loss due to steroid use, and in certain cancers with high propensity to bone, such as multiple myeloma.

Bisphosphonate
Bisphosphonates are a class of drugs that prevent the loss of bone density, used to treat osteoporosis and similar diseases. They are the most commonly prescribed drugs used to treat osteoporosis. They are called bisphosphonates because they have two phosphonate () groups. They are thus also called diphosphonates ('' bis-'' or '' di-'' + ''phosphonate''). Evidence shows that they reduce the risk of fracture in post-menopausal women with osteoporosis. Bone tissue undergoes constant remodeling and is kept in balance (homeostasis) by osteoblasts creating bone and osteoclasts destroying bone. Bisphosphonates inhibit the digestion of bone by encouraging osteoclasts to undergo apoptosis, or cell death, thereby slowing bone loss. The uses of bisphosphonates include the prevention and treatment of osteoporosis, Paget's disease of bone, bone metastasis (with or without hypercalcemia), multiple myeloma, primary hyperparathyroidism, osteogenesis imperfecta, fibrous dysplasia, and o ...
