Advantages of
pharmaceutical dosage forms
A
pharmaceutical dosage form is the entity that is administered to patients so
that they receive an effective dose of a drug. Some common examples are
tablets, capsules, suppositories, injections, suspensions, and transder-mal
patches. Besides providing the mechanism for the safe and convenient delivery
of accurate dosage, pharmaceutical dosage forms are needed for the following
additional reasons:
·
To protect the drug substance from the destructive influence
of atmo-spheric oxygen or humidity (coated
tablets).
·
To protect the drug substance from the destructive influence
of gastric acid after oral administration (enteric-coated
tablets).
·
To conceal the bitter, salty, or offensive taste or odor of
a drug sub-stance (capsules, coated
tablets, and flavored syrup).
·
To provide liquid preparations of substances that are either
insoluble or unstable in the desired vehicle (suspensions).
·
To provide rate-controlled drug action (various controlled-release tables,
capsules, and suspensions).
·
To provide site-specific and local drug delivery (e.g.,
rectal and vagi-nal suppositories).
·
To target the drug at the desired site of action (e.g.,
nanoparticulate systems, liposomes, etc.).
