Pharmacy (42 cards)
Pharmacotherapeutics is the study of the uses of medications in the treatment of disease
Toxicology is the study of poisons, their actions, their detection, and the treatment of the conditions produced by them
Therapeutics is the science of treating disease by any method that will relieve pain, treat or cure diseases and infections, or prolong life
United States Pharmacopeia and National Formulary (USP-NF), which sets standards for the quality, purity, strength, and consistency and provides standards for medications of therapeutic usefulness and pharmaceutical necessity.
Pharmacognosy is the branch of pharmacology dealing with biological, biochemical, and economic features of natural medications and their constituents
Pharmacy is the branch of pharmacology dealing with the preparation, dispensing, and proper use of medications
Posology is the study of the dosages of medicines and medications
Pharmacodynamics is the study of the action or effects of medications on living organisms
Remington: The Science and Practice of Pharmacy is the most widely used text/reference in American pharmacies.This work is known as the “blue bible” of pharmacology.
The study of dosage and the criteria that influence it is called posology.
The average therapeutic doses and are known as “usual adult doses.”
minimum dose (the least amount of medication required to produce a therapeutic effect),
maximum dose (the largest amount of medication that can be given without reaching the toxic effect)
toxic dose (the least amount of medication that will produce symptoms of poisoning).
therapeutic dose is calculated on an average adult male of 24 years who weighs approximately 150 pounds.
MINIMUM LETHAL DOSE.—is the least amount of medication that can produce death.
Factors that affect dosage are Age, weight, sex, race, occupation, habitual use of meds, time of administration, frequency of ad, mode of ad
Subcutaneous is the medication injected just below the skin’s cutaneous layers. Example: Insulin
Intradermal is the medication injected within the dermis layer of the skin. Example: Purified Protein Derivative (PPD).
Intramuscular is the medication injected into the muscle. Example: Procaine Penicillin G.
Vaporization - the process by which a medication is changed from a liquid or solid to a gas or vapor by the use of heat (such as in steam inhalation)
Gas Inhalation - almost entirely restricted to anesthesia
Nebulization - the process by which a medication is converted into a fine spray by the use of compressed gas
Medications are classified according to set criteria and fall into three specific areas: general, chemical, and therapeutic
General: Grouped according to their source whether animal, vegetable, or mineral in origin
Chemical: Grouped by their chemical characteristics
Therapeutic (Pharmacological): Grouped according to their action on the body
Chemical name relates to the chemical and molecular structure. An example is 2,4,7-triamino-6-phenylpteridine
Generic name is often derived from the chemical name
Brand name (trade name) is the proprietary name given by the manufacturer. Brand name is also referred to as the trade name.
Astringents are medications that cause shrinkage of the skin and mucous membranes. Mainly used to stop seepage, weeping, or discharge from mucous membranes
ASTRINGENTS: Aluminum Acetate solution (Burow’s Solution, Domeboro®) is used as a wet to dry dressing for the relief of inflammatory conditions of the skin, such as athlete’s foot, poison ivy, swelling, external otitis, bruises and insect bites.
ASTRINGENTS: Calamine, zinc oxide, glycerin, and bentonite magma in calcium hydroxide (calamine lotion) It is a topical astringent and protectant. It should be applied to blistered, raw, or oozing areas of the skin.
Emollients are bland or fatty substances that may be applied to the skin to make it more pliable and soft. Emollients are available as ointments, creams, or lotions.
EMOLLIENTS: Theobroma oil (cocoa butter) is an excellent emollient with a pleasant odor.
treatment of chapped skin and lips, cracked nipples,
EMOLLIENTS: Petrolatum (petroleum jelly) is a good emollient that provides a highly occlusive, protective barrier.
EMOLLIENTS: Zinc Oxide is a white petrolatum containing approximately 20% zinc oxide powder. Because of its opaqueness, is ideal for protecting the skin and relieving chafing.
Expectorants AKA bronchomucotropic agents. Assit in the romoval of secretions or exudates from the trachea, bronchi, or lungs. Used to treat coughs.
Antitussives are agents that inhibit or suppress the act of coughing.
Guaifenesin and dextromethorphan (Robitussin® DM) acts as an expectorant. It may be useful in symptomatic relief of dry, nonproductive cough, and in the presence of mucous in the respiratory tract.
Dextromethorphan It is used to control non productive coughs by soothing minor throat and bronchial irritations.
Pseudoephedrine Hydrochloride (Sudafed (HCL) is indicated for the symptomatic relief of nasal congestion due to the common cold, hay fever, or other upper respiratory allergies.
Diphenhydramine Hydrochloride (Benadryl®) HCl is given for active and prophylactic treatment of MOTION SICKNESS, as a nighttime sleep aid, and for the symptomatic relief of urticaria, allergic rhinitis
Meclizine Hydrochloride (Antivert®, Bonine®) Meclizine HCl is given to prevent and treat nausea, vomiting, and dizziness of motion sickness.
Antacids are used to counteract hyperacidity in the stomach.
Magnesium Hydroxide (Milk of Magnesia USP) is used for the symptomatic relief of upset stomach associated with hyperacidity, treatment and maintenance of duodenal ulcers, and used to reduce phosphate absorption in patients with chronic renal failure. also has a laxative effect.
Alumina and Magnesia Oral Suspension (Maalox®) Alumina and magnesia oral suspension coats the stomach lining and neutralizes gastric acid.
Antiseptics suppress the growth of microorganisms.
