The topic of drug formulation
and delivery systems
will be explored through
the principles of
drug formulation,
the various dosage forms and
routes of administration,
and how controlled and
sustained release technologies
have advanced to
medication delivery.
We will also explore
how drug properties and
patient specific factors
influence absorption
and bioavailability.
Additionally, emerging
delivery technologies
such as nanotechnology
will be discussed,
along with their
benefits and challenges.
Finally, we will highlight
the unique advantages
and limitations of
different delivery systems and
consider the future directions
in this rapidly evolving field.
Understanding drug formulation
and delivery systems
is essential for effective
and safe medication use.
Formulation combines
the active ingredient
with excipients to create
suitable dosage forms,
such as tablets,
injectables, or creams.
The delivery system
releases the drug at
the target site in
a controlled manner
to maximize effect.
Choice of formulation and system
affects absorption,
onset, compliance,
and efficacy, depending
on drug properties,
patient needs, and
practical considerations.
Medicines come in many forms,
each designed for specific
clinical needs and
patient groups.
Oral tablets and
capsules are most
common due to their
convenience and stability.
Liquids are important for
children or those with
swallowing difficulties.
Injectable forms provide rapid,
controlled or
sustained delivery in
emergencies or when digestion
might degrade the drug,
