- No:140 - antiexudative
counteracting a process of exudation.
- No:141 - antifibrinolytic
- No:142 - antifungal
destructive to fungi, or suppressing their reproduction or growth;
effective against fungal infections.
- No:143 - antigen
(antibody + Gr. gennan to produce) any substance which is capable,
under appropriate conditions, of inducing a specific immune
response and of reacting with the products of that response, that
is, with specific antibody or specifically sensitized T-lymphocytes, or both. Antigens may be
soluble substances, such as
toxins and foreign proteins, or particulate, such as bacteria and
tissue cells; however, only the portion of the protein or
polysaccharide molecule known as the antigenic determinant (q.v.)
combines with antibody or a specific receptor on a lymphocyte.
- No:144 - antihistamine
a drug that counteracts the action of histamine. The
antihistamines are of two types. The conventional ones, as those
used in allergies, block the H1 histamine receptors, whereas the
others block the H2 receptors. Called also antihistaminic.
- No:145 - antihypertensive
an agent that reduces high blood pressure.
- No:146 - anti-infective
an agent that so acts.
- No:147 - anti-inflammatory
counteracting or suppressing inflammation.
- No:148 - antimicrobial
killing microorganisms, or suppressing their multiplication or
- No:149 - antimitotic
inhibiting or preventing mitosis.
- No:150 - antimycotic
suppressing the growth of fungi.
- No:151 - antineoplastic
inhibiting or preventing the development of neoplasms, checking the
maturation and proliferation of malignant cells.
- No:152 - antioestrogenic
counteracting or suppressing oestrogenic activity
- No:153 - antioxidant
one of many widely used synthetic or natural substances added to a
product to prevent or delay its deterioration by action of oxygen
in the air. Rubber, paints, vegetable oils, and prepared foods
commonly contain antioxidants.
- No:154 - antiphlogistic

- No:156 - antipruritic

- No:157 - antipsychotic
effective in the treatment of psychosis. Antipsychotic drugs
(called also neuroleptic drugs and major tranquilizers) are a
chemically diverse (including phenothiazines, thioxanthenes,
butyrophenones, dibenzoxazepines, dibenzodiazepines, and
diphenylbutylpiperidines) but pharmacologically similar class of
drugs used to treat schizophrenic, paranoid, schizoaffective, and
other psychotic disorders; acute delirium and dementia, and manic
episodes (during induction of lithium therapy); to control the
movement disorders associated with Huntington's chorea, Gilles de
la Tourette's syndrome, and ballismus; and to treat intractable
hiccups and severe nausea and vomiting. Antipsychotic agents bind
to dopamine, histamine, muscarinic cholinergic, a-adrenergic, and
serotonin receptors. Blockade of dopaminergic transmission in
various areas is thought to be responsible for their major effects
: antipsychotic action by blockade in the mesolimbic and
mesocortical areas; extrapyramidal side effects (dystonia,
akathisia, parkinsonism, and tardive dyskinesia) by blockade in the
basal ganglia; and antiemetic effects by blockade in the
chemoreceptor trigger zone of the medulla. Sedation and autonomic
side effects (orthostatic hypotension, blurred vision, dry mouth,
nasal congestion and constipation) are caused by blockade of
histamine, cholinergic, and adrenergic receptors.
- No:158 - antipyretic
(anti + Gr. pyretos fever) an agent that relieves or reduces
fever. Called also antifebrile, antithermic and febrifuge.
- No:159 - antiseptic
a substance that inhibits the growth and development of
microorganisms without necessarily killing them. Cf. disinfectant
