Phenytoin
Phenytoin (PHT), sold under the brand name Dilantin among others, is an anticonvulsant, anti-seizure medication. It is useful for the prevention of tonic-clonic seizures (also known as grand mal seizures) and focal seizures, but not absence seizures. The intravenous form, fosphenytoin, is used for status epilepticus that does not improve with benzodiazepines. It may also be used for certain heart arrhythmias or neuropathic pain. It can be taken intravenously or by mouth. The intravenous form generally begins working within 30 minutes and is effective for roughly 24 hours. Blood levels can be measured to determine the proper dose. Common side effects include nausea, stomach pain, loss of appetite, poor coordination, hypertrichosis, increased hair growth, and Gingival hyperplasia, enlargement of the gums. Potentially serious side effects include sleepiness, self harm, liver problems, bone marrow suppression, hypotension, low blood pressure, toxic epidermal necrolysis, and atrop ...

Gingival Hyperplasia
Gingival enlargement is an increase in the size of the gingiva (gums). It is a common feature of gingival disease. Gingival enlargement can be caused by a number of factors, including inflammatory conditions and the side effects of certain medications. The treatment is based on the cause. A closely related term is epulis, denoting a localized tumor (i.e. lump) on the gingiva. Classification The terms gingival hyperplasia and gingival hypertrophy have been used to describe this topic in the past. These are not precise descriptions of gingival enlargement because these terms are strictly histology, histologic medical diagnosis, diagnoses, and such diagnoses require microscope, microscopic analysis of a tissue sample. Hyperplasia refers to an increased number of cell (biology), cells, and hypertrophy refers to an increase in the size of individual cells. As these identifications cannot be performed with a clinical examination and evaluation of the tissue, the term ''gingival enlarge ...

Heinrich Biltz
Heinrich Biltz (26 May 1865 – 29 October 1943) was a German chemist and professor. Life and career Heinrich Biltz was the son of Karl Friedrich Biltz who was a literary scholar and theatre critic His brother Wilhelm Biltz was also a noted chemist. After his university entrance diploma at the Royal Grammar School (Königliches Wilhelm-Gymnasium) in Berlin in 1885 Heinrich began studying chemistry in the Humboldt University of Berlin with August Wilhelm von Hofmann. later studying at the University of Göttingen with Victor Meyer. In 1888 he was awarded his doctorate in natural science with the continuation of research commenced by Victor Meyer on the molecular weight of substances at high temperatures. During this time he also determined the vapour density from Tin (II) chloride and Sulphur. From 8 July 1891 to 1897, Heinrich was a professor of chemistry at the University of Greifswald. In 1897 he became a professor of the Department of Inorganic Chemistry at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Status Epilepticus
Status epilepticus (SE), or status seizure, is a medical condition with abnormally prolonged seizures. It can have long-term consequences, manifesting as a single seizure lasting more than a defined time (time point 1), or 2 or more seizures over the same period without the person returning to normal between them. The seizures can be of the Generalized tonic–clonic seizure, tonic–clonic type, with a regular pattern of contraction and extension of the arms and legs, also known as convulsive status epilepticus, or of types that do not involve contractions, such as absence seizures or complex partial seizures. Convulsive status epilepticus is a life-threatening medical emergency, particularly if treatment is delayed. For convulsive status epilepticus, the most dangerous type, 5 minutes is the time point at which the seizure or seizures would be considered status epilepticus, so this is defined as a convulsion lasting more than 5 minutes, or two convulsions within 5 minutes without ...

WHO Model List Of Essential Medicines
The WHO Model List of Essential Medicines (aka Essential Medicines List or EML), published by the World Health Organization (WHO), contains the medications considered to be most effective and safe to meet the most important needs in a health system. The list is frequently used by countries to help develop their own local lists of essential medicines. , more than 155 countries have created national lists of essential medicines based on the World Health Organization's model list. This includes both Developed country, developed and Developing country, developing countries. The list is divided into core items and complementary items. The core items are deemed to be the most cost-effective options for key health problems and are usable with little additional health care resources. The complementary items either require additional infrastructure such as specially trained health care providers or diagnostic equipment or have a lower cost–benefit ratio. About 25% of items are in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Hypertrichosis
Hypertrichosis (sometimes known as werewolf syndrome) is an abnormal amount of hair growth over the body. The two distinct types of hypertrichosis are generalized hypertrichosis, which occurs over the entire body, and localized hypertrichosis, which is restricted to a certain area. Hypertrichosis can be either congenital (present at birth) or acquired later in life. The excess growth of hair occurs in areas of the skin with the exception of androgen-dependent hair of the pubic area, face, and axillary regions. Several circus sideshow performers in the 19th and early 20th centuries, such as Julia Pastrana, had hypertrichosis. Many of them worked as freaks and were promoted as having distinct human and animal traits. Classification Two methods of classification are used for hypertrichosis. One divides them into either generalized versus localized hypertrichosis, while the other divides them into congenital versus acquired. Congenital Congenital forms of hypertrichosis are ...

Fosphenytoin
Fosphenytoin, also known as fosphenytoin sodium, and sold under the brand name Cerebyx among others, is a water-soluble phenytoin prodrug that is administered intravenously to deliver phenytoin, potentially more safely than intravenous phenytoin. It is used in the acute treatment of convulsive status epilepticus. Fosphenytoin was developed in 1996. Medical uses Fosphenytoin is approved in the United States for the short-term (five days or fewer) treatment of epilepsy when more widely used means of phenytoin administration are not possible or are ill-advised, such as endotracheal intubation, status epilepticus or some other type of repeated seizures; cluster seizure, vomiting, and/or the patient is unalert or not awake or both. Other In 2003, it was reported that even though anticonvulsants are often very effective in mania, and acute mania requires rapid treatment, fosphenytoin had no antimanic effect. Metabolism One milli mole of phenytoin is produced for every milli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Anticonvulsant
Anticonvulsants (also known as antiepileptic drugs, antiseizure drugs, or anti-seizure medications (ASM)) are a diverse group of pharmacological agents used in the treatment of epileptic seizures. Anticonvulsants are also used in the treatment of bipolar disorder and borderline personality disorder, since many seem to act as mood stabilizers, and for the treatment of neuropathic pain. Anticonvulsants suppress the uncontrolled and excessive firing of neurons during seizures and in doing so can also prevent the spread of the seizure within the brain. Conventional antiepileptic drugs have diverse mechanisms of action but many block sodium channels or enhance γ-aminobutyric acid ( GABA) function. Several antiepileptic drugs have multiple or uncertain mechanisms of action. Next to voltage-gated sodium channels and components of the GABA system, their targets include GABAA receptors, the GABA transporter type 1, and GABA transaminase. Additional targets include voltage-gate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Generic Medication
A generic drug is a pharmaceutical drug that contains the same chemical substance as a drug that was originally protected by chemical patents. Generic drugs are allowed for sale after the patents on the original drugs expire. Because the active chemical substance is the same, the medical profile of generics is equivalent in performance compared to their performance at the time when they were patented drugs. A generic drug has the same active pharmaceutical ingredient (API) as the original, but it may differ in some characteristics such as the manufacturing process, pharmaceutical formulation, formulation, excipients, color, taste, and packaging. Although they may not be associated with a particular company, generic drugs are usually subject to government regulations in the countries in which they are dispensed. They are labeled with the name of the manufacturer and a generic non-proprietary name such as the United States Adopted Name (USAN) or International nonproprietary name, Int ...

Bone Marrow Suppression
Bone marrow suppression also known as myelotoxicity or myelosuppression, is the decrease in production of cells responsible for providing immunity (leukocytes), carrying oxygen (erythrocytes), and/or those responsible for normal blood clotting (thrombocytes). Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine. The risk is especially high in cytotoxic chemotherapy for leukemia. In the case of non-small-cell lung cancer, myelosuppression predisposition was shown to be modulated by enhancer mutations. Nonsteroidal anti-inflammatory drugs (NSAIDs), in some rare instances, may also cause bone marrow suppression. The decrease in blood cell counts does not occur right at the start of chemotherapy because the drugs do not destroy the cells already in the bloodstream (these are not dividing rapidly). Instead, the drugs affect new blood cells that are being made by the bone marrow. When myelosuppression is se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Focal Seizures
Focal seizures are seizures that originate within brain networks limited to one hemisphere of the brain. In most cases, each seizure type has a consistent site of onset and characteristic patterns of spread, although some individuals experience more than one type of focal seizure arising from distinct networks. Seizure activity may remain localized or propagate to the opposite hemisphere. Symptoms will vary according to where the seizure occurs. When seizures occur in the frontal lobe, the patient may experience a wave-like sensation in the head. When seizures occur in the temporal lobe, a feeling of déjà vu may be experienced. When seizures are localized to the parietal lobe, a numbness or tingling may occur. With seizures occurring in the occipital lobe, visual disturbances or hallucinations have been reported. , E ...
