The trade name is recognized by being 1. Capitalized. 2. Easy to pronounce. 3. May have a registered mark.
Trade name medications and their generic equivalent must contain exactly the same amount of active ingredients.

Pharmacists are permitted to substitute the generic drug for a prescribed trade name drug unless the prescribing physician requests “no substitutions” or “dispense as written (DAW).”
The dosage margin between the therapeutic effect and toxic effect is called the therapeutic index (TI).
A large initial dose of a medication to quickly reach the TI is called a loading dose or bolus.
A drug form that exerts no pharmacological effect, no therapeutic effect, and has no side effects when administered is called a placebo (“sugar pill”).
All new pharmaceutical drugs are protected by a patent lasting 17 years.
A drug patent means that no other company can manufacture or market an identical drug.

The classifications of ASA include: 1. Non-narcotic analgesic. 2. Non steroidal anti-inflammatory drug (NSAID). 3. Antipyretic. 4. Anticoagulant.
Medications that disintegrate slowly into a liquid form that releases the drug topically into the mouth and throat is called a lozenge, troche, or pastille
The term used to describe a liquid with a watery consistency is aqueous.
The term used to describe a thick liquid is viscous.
A small bottle containing injectable medication with a rubber diaphragm at the bottle neck for needle insertion is called a vial
A small slender container with a narrow neck which houses injectable liquids is called a ampule (Amp)
Liquid medications that contain alcohol (ETOH) are called elixirs (elix.) or tinctures.
Liquid medications that contain no alcohol but are a concentrated solution of sugar, water, and flavorings are called syrups (syp).
Fat globules dispersed throughout a water base is called an emulsion.
Drug particles dispersed throughout a thickened water base is called a gel.
Undissolved particles of a medication to be mixed with a liquid (water) just before use is called a suspension (susp.).
Since the particles will settle, suspensions must be shaken well before use.
The method by which a medication is dispensed is called administration.
Medication applied to the skin or the eyes or ears is called topical (top).
Topical medications include lotions, ointments (ung.) and creams.
Medication patch administration through the skin to the bloodstream is called transdermal.
PO or po or p.o. refers to by mouth (orally).
SL refers to sub lingual (under the tongue).
Inhalation (INH) refers to breathing in medications.
Inhalation administration includes: 1. MDI which stands for metered dose inhaler. 2. Nebulizer (vaporizer). 3. NPPB which stands for noninvasive positive pressure ventilation. 4. Endotracheal (ET) refers to within the trachea (windpipe).
NG {ng} refers to nasogastric tube.
Gastrostomy (G tube) or jejunostomy gavage (J tube) refers to a feeding tube
Rectal ® usually refers to suppositories and enemas.
Vaginal (Vag.) usually refers to suppositories, creams, foams, and douches.
Parenteral (hypodermic) routes include: 1. Intradermal (ID) which refers to within the skin
Common ID injections include Mantoux, PPD, and tine.
. subQ or subcu {subq, SC, SQ} which stands for subcutaneous injection.
A common medication administered subcutaneously is insulin.
. I.M. or IM which stands for intramuscular injection
. I.V. or IV which stands for intravenous injection.
. IVP which stands for intravenous push.
. IVPB which stands for intravenous piggyback.
Intra-articular refers to medication administered into a joint.
Intrathecal refers to spinal medication.
Spinal anesthesia is AKA epidural or caudal or saddle block
Movement of a drug from the site of administration into the bloodstream is called absorption.
Most medications are detoxified by the liver.
Most medications are excreted by the kidneys.
The drug’s main action for which it was prescribed by the physician is called the therapeutic (beneficial) effect
Drug actions that are undesirable but not unexpected are called side effects
Severe side effects are called adverse effects.
Poisonous effects of a drug are called toxic effects
An unusual or exaggerated allergic reaction to a medication is called anaphylaxis.
Undesirable interaction of drugs is called incompatibility
A unique reaction to a medication is called an idiosyncrasy
A drug that deactivates another drug is called an antagonist.
Two drugs combining to produce an effect greater than the independent effects of each is called synergism.
An example of a beneficial synergistic effect is Tylenol #3 which contains acetaminophen and codeine.
Together they provide more analgesic effect than either can separately.
An example of an undesirable synergistic effect is the combination of antihistamines and alcohol which can cause unusual drowsiness.
The synergistic effect of tranquilizers and alcohol can cause death.
