Term
Tablets
Definition
1.Most popular dosage form
2.Prepared by mechanical compression
3.Dissolution=must dissolved in the tomach before it can elict pharmacological effect- so this means that it wll have the slowest absorption
Term
Chewable tablets
Definition
1.chewed and dissolved in the mouth prior to swallowing
2.they also can be swallowed whole
Term
Enteric-coated tablets
Definition
1.special coating over tablet to prevent the dissolution within the stomach.
2.these tablets are meant to dissolve in the intestines only
3.should NEVER be chewed, broken or crushed prior to ingestion
Term
Sublingual tablets
Definition
1.placed"under the tongue" where the active ingredient is quickly absorbed into the bloodstream
--absorption is not in the GI tract..This form is faster absorbed than tablets
2. avoids the "first pass" effect-this is where the drug circulates throughout the body before it is broken down in the liver(metabolized)
Term
Buccal tablets
Definition
1."between cheek and gum"
2.drug is dissolved slowly over a period of time
Term
Film-coated tablets
Definition
- Important Biaxin and Depakote are examples.
1) special coating that masks the objectionable odor or taste
2) prevents deterioration due to light and air
Term
G. Sustained, timed-release tablets
Definition
1) active ingredient is released at a constant rate for a prolonged period of time
2) “long-acting”, “delayed-release”, “prolonged-action”
Term
Lozenges
Definition
1) “troches or pastilles”
2) meant to dissolve slowly in the mouth to keep the drug in contact with the mouth or throat longer
Term
Pellets
Definition
cylinder shaped tablets for implantation just under the skin for continuous drug absorption
Term
Capsules
Definition
1) drug is enclosed within a gelatin shell.
2) after 10 to 30 minutes with the stomach, the gelatin capsule dissolves and the drug is released
3) eliminates bad tastes and odors of drugs
Term
Effervescent tablets
Definition
1) active ingredient + sodium bicarbonate +citric acid (or tartaric acid) acid/base reaction causes a release
of carbon dioxide gas = effervescence
2) masks the taste of unpleasant, salty, or bitterness of medication
Term
Syrups- = Think SUGAR
Definition
High concentrations of sugar hinders bacteria growth.
Examples: antibiotics, cough preparations
Term
Solutions (Soln
Definition
drug is uniformly dispersed throughout the liquid. (it doesn’t settle to the bottom)
Therefore there is no need for a shake well sticker. If you hold the liquid up to the light you will not see
any drug floating around. Example: Albuterol Solution
Term
Suspensions (Susp)
Definition
The medication is insoluble in the liquid. (does not dissolve)
If you hold this liquid up to the light you will see little particles floating around and then settle.
These medications require a shake well sticker because the medication settles at the bottom and the
patient will not get the correct dose if not shaken. Example: Bactrim Suspension
Term
Elixer-
Definition
sweetened water with alcohol. If the medication is an elixir, it contains alcohol. Not for babies.
