A carbonic anhydrase inhibitor that is used as a diuretic and in the treatment of glaucoma.
Carbonic Anhydrase Inhibitors
A class of compounds that reduces the secretion of H+ ions by the proximal kidney tubule through inhibition of CARBONIC ANHYDRASES.
A carbonic anhydrase inhibitor used as diuretic and in glaucoma. It may cause hypokalemia.
One of the CARBONIC ANHYDRASE INHIBITORS that is sometimes effective against absence seizures. It is sometimes useful also as an adjunct in the treatment of tonic-clonic, myoclonic, and atonic seizures, particularly in women whose seizures occur or are exacerbated at specific times in the menstrual cycle. However, its usefulness is transient often because of rapid development of tolerance. Its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition. (From Smith and Reynard, Textbook of Pharmacology, 1991, p337)
A biguanide hypoglycemic agent used in the treatment of non-insulin-dependent diabetes mellitus not responding to dietary modification. Metformin improves glycemic control by improving insulin sensitivity and decreasing intestinal absorption of glucose. (From Martindale, The Extra Pharmacopoeia, 30th ed, p289)
Ethics Committees, Research
An international agreement of the World Medical Association which offers guidelines for conducting experiments using human subjects. It was adopted in 1962 and revised by the 18th World Medical Assembly at Helsinki, Finland in 1964. Subsequent revisions were made in 1975, 1983, 1989, and 1996. (From Encyclopedia of Bioethics, rev ed, 1995)
Committees established by professional societies, health facilities, or other institutions to consider decisions that have bioethical implications. The role of these committees may include consultation, education, mediation, and/or review of policies and practices. Committees that consider the ethical dimensions of patient care are ETHICS COMMITTEES, CLINICAL; committees established to protect the welfare of research subjects are ETHICS COMMITTEES, RESEARCH.
Clinical Trials Data Monitoring Committees
Committees established to review interim data and efficacy outcomes in clinical trials. The findings of these committees are used in deciding whether a trial should be continued as designed, changed, or terminated. Government regulations regarding federally-funded research involving human subjects (the "Common Rule") require (45 CFR 46.111) that research ethics committees reviewing large-scale clinical trials monitor the data collected using a mechanism such as a data monitoring committee. FDA regulations (21 CFR 50.24) require that such committees be established to monitor studies conducted in emergency settings.
An ocular disease, occurring in many forms, having as its primary characteristics an unstable or a sustained increase in the intraocular pressure which the eye cannot withstand without damage to its structure or impairment of its function. The consequences of the increased pressure may be manifested in a variety of symptoms, depending upon type and severity, such as excavation of the optic disk, hardness of the eyeball, corneal anesthesia, reduced visual acuity, seeing of colored halos around lights, disturbed dark adaptation, visual field defects, and headaches.

Nevus, Sebaceous of Jadassohn
A syndrome characterized by lesions occurring on the face, scalp, or neck which consist of congenital hypoplastic malformations of cutaneous structures and which over time undergo verrucous hyperplasia. Additionally it is associated with neurological symptoms and skeletal, ophthalmological, urogenital, and cardiovascular abnormalities.
The interchange of goods or commodities, especially on a large scale, between different countries or between populations within the same country. It includes trade (the buying, selling, or exchanging of commodities, whether wholesale or retail) and business (the purchase and sale of goods to make a profit). (From Random House Unabridged Dictionary, 2d ed, p411, p2005 & p283)
