Intrathecally
Intrathecal administration is a route of administration for drugs via an injection into the spinal canal, or into the subarachnoid space so that it reaches the cerebrospinal fluid (CSF) and is useful in spinal anesthesia, chemotherapy, or pain management applications. This route is also used to introduce drugs that fight certain infections, particularly post-neurosurgical. The drug needs to be given this way to avoid being stopped by the blood–brain barrier. The same drug given orally must enter the blood stream and may not be able to pass out and into the brain. Drugs given by the intrathecal route often have to be compounded specially by a pharmacist or technician because they cannot contain any preservative or other potentially harmful inactive ingredients that are sometimes found in standard injectable drug preparations. The route of administration is sometimes simply referred to as "intrathecal"; however, the term is also an adjective that refers to something occurring in ...

Baclofen
Baclofen, sold under the brand name Lioresal among others, is a medication used to treat muscle spasticity such as from a spinal cord injury or multiple sclerosis. It may also be used for hiccups and muscle spasms near the end of life. It is taken by mouth or by delivery into the spinal canal. Common side effects include sleepiness, weakness, and dizziness. Serious side effects may occur if baclofen is rapidly stopped including seizures and rhabdomyolysis. Use in pregnancy is of unclear safety while use during breastfeeding is probably safe. It is believed to work by decreasing levels of certain neurotransmitters. Baclofen was approved for medical use in the United States in 1977. It is available as a generic medication. In 2020, it was the 108th most commonly prescribed medication in the United States, with more than 6million prescriptions. Medical uses Baclofen is primarily used for the treatment of spastic movement disorders, especially in instances of spinal cord inju ...

Vincristine
Vincristine, also known as leurocristine and marketed under the brand name Oncovin among others, is a chemotherapy medication used to treat a number of types of cancer. This includes acute lymphocytic leukemia, acute myeloid leukemia, Hodgkin's disease, neuroblastoma, and small cell lung cancer among others. It is given intravenously. Most people experience some side effects from vincristine treatment. Commonly it causes a change in sensation, hair loss, constipation, difficulty walking, and headaches. Serious side effects may include neuropathic pain, lung damage, or low white blood cells which increases the risk of infection. Use during pregnancy may result in birth defects. It works by stopping cells from dividing properly. It is vital that it not be given intrathecally, as this causes paralysis and in most cases, death. Vincristine was first isolated in 1961. It is on the World Health Organization's List of Essential Medicines. It is a vinca alkaloid that can be obtained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Analgesic
An analgesic drug, also called simply an analgesic (American English), analgaesic (British English), pain reliever, or painkiller, is any member of the group of drugs used to achieve relief from pain (that is, analgesia or pain management). It is typically used to induce cooperation with a medical procedure. Analgesics are conceptually distinct from anesthetics, which temporarily reduce, and in some instances eliminate, sensation, although analgesia and anesthesia are neurophysiologically overlapping and thus various drugs have both analgesic and anesthetic effects. Analgesic choice is also determined by the type of pain: For neuropathic pain, traditional analgesics are less effective, and there is often benefit from classes of drugs that are not normally considered analgesics, such as tricyclic antidepressants and anticonvulsants. Various analgesics, such as many NSAIDs, are available over the counter in most countries, whereas various others are prescription drugs owing ...

Pain Management
Pain management is an aspect of medicine and health care involving relief of pain (pain relief, analgesia, pain control) in various dimensions, from acute and simple to chronic and challenging. Most physicians and other health professionals provide some pain control in the normal course of their practice, and for the more complex instances of pain, they also call on additional help from a specific medical specialty devoted to pain, which is called pain medicine. Pain management often uses a multidisciplinary approach for easing the suffering and improving the quality of life of anyone experiencing pain, whether acute pain or chronic pain. Relief of pain in general (analgesia) is often an acute affair, whereas managing chronic pain requires additional dimensions. The typical pain management team includes medical practitioners, pharmacists, clinical psychologists, physiotherapists, occupational therapists, recreational therapists, physician assistants, nurses, and dentists. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Itch
Itch (also known as pruritus) is a sensation that causes the desire or reflex to scratch. Itch has resisted many attempts to be classified as any one type of sensory experience. Itch has many similarities to pain, and while both are unpleasant sensory experiences, their behavioral response patterns are different. Pain creates a withdrawal reflex, whereas itch leads to a scratch reflex. Unmyelinated nerve fibers for itch and pain both originate in the skin; however, information for them is conveyed centrally in two distinct systems that both use the same nerve bundle and spinothalamic tract. Classification Most commonly, an itch is felt in one place. If it is felt all over the body, then it is called ''generalized itch'' or ''generalized pruritus''. If the sensation of itching persists for six weeks or longer, then it is called ''chronic itch'' or ''chronic pruritus''. ''Chronic idiopathic pruritus'' or ''essential pruritus'' is a rare form of itch that persists for longer th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spastic Cerebral Palsy
Spastic cerebral palsy is the type of cerebral palsy characterized by spasticity or high muscle tone often resulting in stiff, jerky movements. Cases of spastic CP are further classified according to the part or parts of the body that are most affected. Such classifications include spastic diplegia, spastic hemiplegia, spastic quadriplegia, and in cases of single limb involvement, spastic monoplegia. Spastic cerebral palsy affects the motor cortex of the brain, a specific portion of the cerebral cortex responsible for the planning and completion of voluntary movement. Spastic CP is the most common type of overall cerebral palsy, representing roughly 80% of cases. Spastic CP is a permanent condition and will affect an individual across the lifespan. The brain injury that causes spastic CP remains stable over time, but the way spasticity affects a person can change. For example, with age they may develop bone deformities from the pull of spastic muscles, muscular deterioration, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vinca Alkaloid
''Vinca'' alkaloids are a set of anti-mitotic and anti-microtubule alkaloid agents originally derived from the periwinkle plant ''Catharanthus roseus'' (basionym ''Vinca rosea'') and other ''vinca'' plants. They block beta-tubulin polymerization in a dividing cell. Sources The Madagascan periwinkle ''Catharanthus roseus'' L. is the source for a number of important natural products, including catharanthine and vindoline and the vinca alkaloids it produces from them: leurosine and the chemotherapy agents vinblastine and vincristine, all of which can be obtained from the plant. The newer semi-synthetic chemotherapeutic agent vinorelbine is used in the treatment of non-small-cell lung cancer and is not known to occur naturally. However, it can be prepared either from vindoline and catharanthine or from leurosine, in both cases by synthesis of anhydrovinblastine, which "can be considered as the key intermediate for the synthesis of vinorelbine." The leurosine pathway uses the Nug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thiotepa
Thiotepa (INN), sold under the brand name Tepadina, is a medication used to treat cancer. Thiotepa is an organophosphorus compound with the formula (C2H4N)3PS. It is an analog of ''N'',''N′'',''N′′''-triethylenephosphoramide (TEPA), which contains tetrahedral phosphorus and is structurally akin to phosphate. It is manufactured by heating aziridine with thiophosphoryl chloride. Medical uses Thiotepa is indicated for use in combination with other chemotherapy agents to treat cancer. This can be with or without total body irradiation (TBI), as a conditioning treatment prior to allogeneic or autologous hematopoietic progenitor cell transplantation (HPCT) in hematological diseases in adults and children. These diseases include Hodgkin's disease and leukaemia. Thiotepa is also used with high-dose chemotherapy with HPCT support to treat certain solid tumors in adult and children. Thiotepa is used in the palliation of many neoplastic diseases. The best results ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocortisone
Hydrocortisone is the name for the hormone cortisol when supplied as a medication. Uses include conditions such as adrenocortical insufficiency, adrenogenital syndrome, high blood calcium, thyroiditis, rheumatoid arthritis, dermatitis, asthma, and COPD. It is the treatment of choice for adrenocortical insufficiency. It can be given by mouth, topically, or by injection. Stopping treatment after long-term use should be done slowly. Side effects may include mood changes, increased risk of infection, and edema (swelling). With long-term use common side effects include osteoporosis, upset stomach, physical weakness, easy bruising, and candidiasis (yeast infections). While used, it is unclear if it is safe during pregnancy. Hydrocortisone is a glucocorticoid and works as an anti-inflammatory and by immune suppression.

Ziconotide
Ziconotide (SNX–111; Prialt), also called intrathecal ziconotide (ITZ) because of its administration route, is an atypical analgesic agent for the amelioration of severe and chronic pain. Derived from ''Conus magus'', a cone snail, it is the synthetic form of an ω-conotoxin peptide. It is 1,000 times as powerful as morphine. In December 2004 the Food and Drug Administration approved ziconotide when delivered as an infusion into the cerebrospinal fluid using an intrathecal pump system. Discovery Ziconotide is derived from the toxin of the cone snail species ''Conus magus''. Scientists have been intrigued by the effects of the thousands of chemicals in marine snail toxins since the initial investigations in the late 1960s by Baldomero Olivera. Olivera, now a professor of biology in the University of Utah, was inspired by accounts of the deadly effects of these toxins from his childhood in the Philippines. Ziconotide was discovered in the early 1980s by University of Utah re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
