Category Names, Results, and Descriptions


Decongestants (0) see Nasal Decongestants

Defoaming Agents (0) see Antifoaming Agents

Defoliants, Chemical (3) • Herbicides that remove leaves from trees and growing plants. They may be either organic or inorganic. Several of the more persistent types have been used in military operations and many are toxic. (From Hawley's Condensed Chemical Dictionary, 11th ed) MeSH

Delayed-Action Preparations (3) • Dosage forms of a drug that act over a period of time by controlled-release processes or technology. MeSH

Dental Disinfectants (1) • Chemicals especially for use on instruments to destroy pathogenic organisms. (Boucher, Clinical Dental Terminology, 4th ed) MeSH

Dental Materials (27) • Materials used in the production of dental bases, restorations, impressions, prostheses, etc. MeSH

Dental Polishes (0) see Dentifrices

Dentifrices (1) • Any preparations used for cleansing teeth; they usually contain an abrasive, detergent, binder and flavoring agent and may exist in the form of liquid, paste or powder; may also contain medicaments and caries preventives. MeSH

Depot Preparations (0) see Delayed-Action Preparations

Dermatologic Agents (145) • Drugs used to treat or prevent skin disorders or for the routine care of skin. MeSH

Desiccants (0) see Hygroscopic Agents

Desickling Agents (0) see Antisickling Agents

Designer Drug (1)

Detergents (32) • Purifying or cleansing agents, usually salts of long-chain aliphatic bases or acids, that exert cleansing (oil-dissolving) and antimicrobial effects through a surface action that depends on possessing both hydrophilic and hydrophobic properties. MeSH

Diagnostic Uses of Chemicals (126)

Dialysis Solutions (1)

Digestants (0) see Gastrointestinal Agents

Dipeptidyl-Peptidase IV Inhibitors (13) • Compounds that suppress the degradation of INCRETINS by blocking the action of DIPEPTIDYL-PEPTIDASE IV. This helps to correct the defective INSULIN and GLUCAGON secretion characteristic of TYPE 2 DIABETES MELLITUS by stimulating insulin secretion and suppressing glucagon release. MeSH

Disinfectants (34) • Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed) MeSH

Diuretic Effect (0) see Diuretics

Diuretics (72) • Agents that promote the excretion of urine through their effects on kidney function. MeSH

Diuretics, Osmotic (2) • Compounds that increase urine volume by increasing the amount of osmotically active solute in the urine. Osmotic diuretics also increase the osmolarity of plasma. MeSH

Diuretics, Thiazide (0) see Sodium Chloride Symporter Inhibitors

DNA Gyrase Inhibitors (0) see Topoisomerase II Inhibitors

DNA Polymerase Inhibitors (0) see Nucleic Acid Synthesis Inhibitors

DNA Synthesis Inhibitors (0) see Nucleic Acid Synthesis Inhibitors

DNA, Antisense (1)

DOPA Decarboxylase Inhibitors (0) see Aromatic Amino Acid Decarboxylase Inhibitors

Dopamine Agents (168) • Any drugs that are used for their effects on dopamine receptors, on the life cycle of dopamine, or on the survival of dopaminergic neurons. MeSH

Dopamine Agonists (61) • Drugs that bind to and activate dopamine receptors. MeSH

Dopamine Antagonists (78) • Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME. MeSH

Dopamine D2 Receptor Antagonists (10) • Compounds and drugs that bind to and inhibit or block the activation of DOPAMINE D2 RECEPTORS. MeSH

Dopamine Effect (0) see Dopamine Agents

Dopamine Uptake Inhibitors (25) • Drugs that block the transport of DOPAMINE into axon terminals or into storage vesicles within terminals. Most of the ADRENERGIC UPTAKE INHIBITORS also inhibit dopamine uptake. MeSH

Drug Carriers (4) • Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers. MeSH

Dyes (0) see Coloring Agents
