This document discusses transdermal patches, including their design, components, types, and applications. It begins with background information on transdermal patches and how they deliver medication through the skin. It then describes the key components of patches, including the backing, adhesive, drug reservoir, and release liner. The main types of patches are outlined as single-layer drug-in-adhesive, multi-layer drug-in-adhesive, reservoir, matrix, and vapor patches. Popular applications mentioned include nicotine patches, hormonal patches, and patches for pain, hypertension, and depression. The document also addresses transdermal patch design considerations, manufacturing processes, and common uses.

2. Background
A Transdermal Patch is a medicated adhesive patch
that is placed on the skin to deliver a specific dose of
medication through the skin and into the bloodstream.
Often, this promotes healing to an injured area of the
body. An advantage of a transdermal drug delivery route
over other types of medication delivery such as oral,
topical, intravenous, intramuscular, etc. is that the patch
provides a controlled release of the medication into the
patient, usually through either a porous membrane
covering a reservoir of medication or through body heat
melting thin layers of medication embedded in the
adhesive.

Simple DIA designs are popular, as they can be made by adding

then laminating them to a backing layer.

while the extra membranes create a more complex manufacturing

of drug into an adhesive, as high as 30 per cent, compared to
around 5 per cent in DIA designs.

13. Advantages of Transdermal Drug Delivery
 do not put too much load on digestive
system and liver
 avoid the pain on injection
 eliminate the adverse effects associated
with excessive absorption of drugs taken
orally
 thereby alleviate anxiety
 offer more comfort to patients
 produce excellent prolonged effects
 administration can be visually confirmed

o flushing
some other side effects cab be serious
 slow or fast heart beat
 worsening chest pain
 fainting
 rash

Patches
Treatment of Ischemic Heart Disease

when applied on chest or upper abdomen
release the drug
contribute to therapeutic improvement of cardic function.
For Local Anesthesia
with tulobuterol
( Respiratory function has a circadian rhythem and is known to decrease from
around midnight to early morning , generally known as "morning dip"
paients suffering from bronchial asthma, accacks often occur in the early morning
, caused by morning dip,
is a major stress factor
this patch offers a long lasting brochodilating effect

17. Special precautions
when using transdermal patches
• apply patch to clean, dry, unbroken skin
• apply patch firmly ( it may take 20-30 seconds to get it
stick firmly in place)
• wash your hands after applying
• use only one patch at a time
• if ou need to conduct MRI test , the patch may need to
be removed
• if you develop skin irritation ( due to adhesive ) , appy
the next patch on another area
• when you remove the skin patch, fold it so the
adhesive edges stick together
• gently wash the area with soap and water

18. The main
Components
The main components to a transdermal patch are:
Liner -
Protects the patch during storage. The liner is
removed prior to use.
Drug Drug solution in direct contact with release liner
Adhesive Serves to adhere the components of the patch
together along with adhering the
patch to the
skin
Membrane - Controls the release of the drug from the
reservoir and multi-layer patches
Backing Protects the patch from the outer environment
28-01-2014

19. There are five main types
of transdermal patches.
Single-layer Drug-in-Adhesive
Multi-layer Drug-in-Adhesive
Reservoir
Matrix
Vapour Patch
28-01-2014
19

20. Single-layer Drug-in-Adhesive
The adhesive layer of this system also contains the drug. In this
type of patch the adhesive layer not only serves to adhere the
various layers together, along with the entire system to the skin,
but is also responsible for the releasing of the drug. The
adhesive layer is surrounded by a temporary liner and a
backing.
28-01-2014
20

21. Multi-layer Drug-in-Adhesive
The multi-layer drug-in adhesive patch is similar to the singlelayer system in that both adhesive layers are also responsible for
the releasing of the drug.One of the layers is for immediate
release of the drug and other layer is for control release of drug
from the reservoir. The multi-layer system is different however
that it adds another layer of drug-in-adhesive, usually separated
by a membrane (but not in all cases). This patch also has a
temporary liner-layer and a permanent backing.
28-01-2014
21

22. Reservoir
Unlike the Single-layer and Multi-layer Drug-in-adhesive
systems the reservoir transdermal system has a separate drug
layer. The drug layer is a liquid compartment containing a drug
solution or suspension separated by the adhesive layer. This
patch is also backed by the backing layer. In this type of system
the rate of release is zero order.
28-01-2014
22

23. Matrix
The Matrix system has a drug layer of a semisolid matrix
containing a drug solution or suspension. The adhesive layer in
this patch surrounds the drug layer partially overlaying it. Also
known as a monolithic device.
28-01-2014
23

24. Vapour Patch
In this type of patch the adhesive layer not only serves to adhere
the various layers together but also to release vapour. The
vapour patches are new on the market and they release essential
oils for up to 6 hours. The vapour patches release essential oils
and are used in cases of decongestion mainly. Other vapour
patches on the market are controller vapour patches that
improve the quality of sleep. Vapour patches that reduce the
quantity of cigarettes that one smokes in a month are also
available on the market.
