To investigate the bioequivalence between two compounds (phenytoin and epamin) by a randomized, single dose study under fasting conditions in healthy volunteers.
Bioequivalence study in healthy volunteers
Allocation: Randomized, Endpoint Classification: Bio-equivalence Study, Intervention Model: Crossover Assignment, Masking: Open Label
Pfizer Investigational Site
Published on BioPortfolio: 2014-08-27T03:13:41-0400
Mexican healthy volunteers will receive the current form of the drug (under the name of Epamin) as well as Pfizer's compound (Phenytoin). Bioequivalence will be tested.
Phenytoin is a medicine used to treat seizures. If too much is taken, patients have ill effects including sleepiness, unsteady gait, and eye problems. The amount of drug in their system ca...
The use of phenytoin metabolism to produce S-HPPH accounts for more than 85% of its metabolism. This metabolic pathway is mediated by the activity of CYP2C9. The purpose of the present st...
This study is designed to test if megestrol acetate induces changes in declarative memory in healthy controls and if pre-administration of phenytoin can ameliorate any induced cognitive im...
The purpose of this research is to determine if patients who receive phenytoin (also commonly known as Dilantin) before taking corticosteroids will show less memory impairment and hypomani...
Phenytoin is an effective anticonvulsant for focal epilepsy. Its use can be associated with long-term adverse effects including cerebellar ataxia. Whilst phenytoin is toxic to Purkinje cells in vitro;...
The U.S. Pharmacopeia defines excipients as substances other than the active pharmaceutic ingredient (API) that are added in a drug delivery system in order to aid in the manufacturing process and enh...

The induction of cytochrome P450 enzymes (CYPs) in response to drug treatment is a significant contributing factor to drug-drug interactions, which may reduce therapeutic efficacy and/or cause toxicit...
Epilepsy is a common neurological disorder that affects learning and memory. Recently it has been shown that mild foot electrical stimulation (MFES) can increase learning and memory in normal rats. Pe...
An anticonvulsant that is used in a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.
Healthy People Programs are a set of health objectives to be used by governments, communities, professional organizations, and others to help develop programs to improve health. It builds on initiatives pursued over the past two decades beginning with the 1979 Surgeon General's Report, Healthy People, Healthy People 2000: National Health Promotion and Disease Prevention Objectives, and Healthy People 2010. These established national health objectives and served as the basis for the development of state and community plans. These are administered by the Office of Disease Prevention and Health Promotion (ODPHP). Similar programs are conducted by other national governments.
Governmental guidelines and objectives pertaining to public food supply and nutrition including recommendations for healthy diet and changes in food habits to ensure healthy diet.
An anticonvulsant used to control grand mal and psychomotor or focal seizures. Its mode of action is not fully understood, but some of its actions resemble those of PHENYTOIN; although there is little chemical resemblance between the two compounds, their three-dimensional structure is similar.
Surgical reinnervation of a denervated peripheral target using a healthy donor nerve and/or its proximal stump. The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
