LilleyChpt 36 Antihistamines, Decongestants, Antitussives, and Expectorants

a drug that reduces coughing often by inhibiting neural activity in the cough center of the central nervous system

any of the hormones produced by the adrenal cortex, either in natrual or synthetic drug form

they influence or control many key processes in the body, such as carbohydrate and protein metabolism, the maintenance of serum glucose levels, electrolytes and water balance and the function of the cardiovascular system, skeletal muscle, kidneys, and other organs

drugs that reduce congestion or swelling, especially of the upper or lower respiratory tract

a method of treating disease based on observations and experience without knowledge of the precise cause of or mechanism responsible for the disorder or the way in which the therapeutic drug or procedure produces improvement or cure

drugs that increase the flow of fluid int the respiratory tract, usually by reducing the viscosity of bronchial and tracheal secretions, and facilitate their removal by coughing and ciliary action

drugs that compete with histamine for binding sites on histamine receptors

a highly contagious infection of the respiratory tract caused by a myxovirus and transmitted by airborne droplets

newer medication that work preipherally to block the actions of histamine and therefore do not have the central vervous system effects of many of the older antihistamines

drugs that compete with histamine for binding sites on histamine receptors

also called second-generation antihistamines and peripherally acting antihistamines

an irritation of the respiratory tract occuring in response to an irritation of the gastrointestinal tract

any of the 100 serologically distinct ribonucle acid (RNA) viruses that cause about 40% of acute respiratory illnesses

a class of drug whose effects mimic those resulting form the stimulation of organs and structures by the sympathetic nervous system

they do this by occupying adrenegic receptor sites and acting as agonists or by increasing the release of norepinephrine at postganglionic nerve endings

any infections disease of the upper respiratory tract, including the common cold, laryngitis, pharyngitis, rhinitis, sinusitis, and tonsillitis

drugs that stimulate the sympathetic nerve fibers of the autonomic nervous system which use epinephrine or epinephrine-like substances as neurotransmitters

drugs that exert an action opposite to that of another drug or compete for the same receptor sites

drugs that block the action of acetylcholine and similiar substances at acetylcholine receptors

results in hihibition of the transmission of parasympathetic nerve impulses

substances that, upon entering to the body, are capable of inducing specific immune responses and in turn reacting with the specific products of such responses, such as certian antiboidies and specifically sensitized T lymphocytes.

they can be soluble or particulate or insoluble

substances capable of reducing the physiologic and pharmacologic effects of histamine, including a wide variety of drugs that block histamine receptor
