Emetics (5) • Agents that cause vomiting. They may act directly on the gastrointestinal tract, bringing about emesis through local irritant effects, or indirectly, through their effects on the chemoreceptor trigger zone in the postremal area near the medulla. MeSH

Emollients (3) • Oleagenous substances used topically to soothe, soften or protect skin or mucous membranes. They are used also as vehicles for other dermatologic agents. MeSH

Emulsions (1)

Endocrine Disruptors (1)

Endothelin a Receptor Antagonists (3)

Endothelin B Receptor Antagonists (2)

Endothelin Receptor Antagonists (24) • Compounds and drugs that bind to and inhibit or block the activation of ENDOTHELIN RECECPTORS. MeSH

Endothelium-Dependent Relaxing Factors (1) • Paracrine substances produced by the VASCULAR ENDOTHELIUM with VASCULAR SMOOTH MUSCLE relaxation (VASODILATION) activities. Several factors have been identified, including NITRIC OXIDE and PROSTACYCLIN. MeSH

Environmental Pollutants (34) • Substances or energies, for example heat or light, which when introduced into the air, water, or land threaten life or health of individuals or ECOSYSTEMS. MeSH

Enzyme Activators (13) • Compounds or factors that act on a specific enzyme to increase its activity. MeSH

Enzyme Activators (1)

Enzyme Inhibitor (Angiotensin-Converting) (2)

Enzyme Inhibitors (1626) • Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. MeSH

Enzyme Reactivators (7)

Epithelial Sodium Channel Blockers (3) • A subclass of sodium channel blockers that are specific for EPITHELIAL SODIUM CHANNELS. MeSH

Estradiol Receptor Antagonists (0) see Estrogen Receptor Antagonists

Estrogen Antagonists (38) • Compounds which inhibit or antagonize the action or biosynthesis of estrogenic compounds. MeSH

Estrogen Effect (0) see Estrogens

Estrogen Receptor Antagonists (1) • Compounds and drugs that bind to and block or inhibit the activation of ESTROGEN RECEPTORS. MeSH

Estrogen Receptor Modulators (33) • Substances that possess antiestrogenic actions but can also produce estrogenic effects as well. They act as complete or partial agonist or as antagonist. They can be either steroidal or nonsteroidal in structure. MeSH

Estrogen Synthesis Inhibitors (0) see Steroid Synthesis Inhibitors

Estrogens (40) • Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds. MeSH

Estrogens, Non-Steroidal (25) • Non-steroidal compounds with estrogenic activity. MeSH

Excipients (11) • Usually inert substances added to a prescription in order to provide suitable consistency to the dosage form. These include binders, matrix, base or diluent in pills, tablets, creams, salves, etc. MeSH

Excitatory Amino Acid Agents (61)

Excitatory Amino Acid Agonists (16) • Drugs that bind to and activate excitatory amino acid receptors. MeSH

Excitatory Amino Acid Antagonists (59) • Drugs that bind to but do not activate excitatory amino acid receptors, thereby blocking the actions of agonists. MeSH

Excitotoxins (0) see Neurotoxins

Exohemagglutinins (0) see Hemagglutinins

Expectorants (19) • Agents that increase mucous excretion. Mucolytic agents, that is drugs that liquefy mucous secretions, are also included here. MeSH

Explosive Agents (13) • Substances that are energetically unstable and can produce a sudden expansion of the material, called an explosion, which is accompanied by heat, pressure and noise. Other things which have been described as explosive that are not included here are explosive action of laser heating, human performance, sudden epidemiological outbreaks, or fast cell growth. MeSH
