Description

NOVEL MEDICATION DISPSENSER
FIELD OF THE INVENTION
The invention is directed to a device to help patients handle and keep track
of multiple medications,
more specifically, to a pharmaceutical formulation dispenser.
BACKGROUND OF THE INVENTION
The most common problems encountered in the health care system is patient
compliance. Patients
might do the following: continue to take medications that has been stopped by
the doctor; continue to take
medications that has expired but they still have it in their stock; take the
wrong strength of the medication;
take the medication at the wrong time; mixing up their medications leading to
drug-drug interactions; taking
their medications with or without food leading to drug-food interaction;
taking another patient's medication
by error if they live in the same facility; forgetting to take their
medications all together.
Patient's non-compliance is usually due to: ageing (as people grow older they
tend to be more
forgetful; disability (whether cognitive or physical); poor communication with
appropriate health care
provider; and carelessness.
The consequences of non-compliance can be detrimental to both patient and the
economy.
Researchers have shown that the impact of non-compliance on patient outcomes.
Each year drug non-
compliance is the cause of: 10% of all hospital admissions; 25% of hospital
admissions for the elderly; 23%
of all nursing home admissions; and adverse drug reactions are a leading cause
of patient mortality.
Not only will closing the medication adherence gap be expected to improve the
quality of
healthcare, and promote enhanced patient outcomes but it is also expected to
encourage better chronic care
management as well as also significantly reducing the overall cost to Canadian
healthcare system.
Moreover, some financial impact on the healthcare system from medication non-
adherence is
estimated to annually cost of the Canadian healthcare system between $7
billion and $9 billion. These costs
include additional physician visits, extra laboratory tests, additional drug
therapy, hospital ER visits,
hospital admissions and short-term disability insurance payments.
Current approaches to improve compliance: current weekly organizers have the
same layout in
terms of days of the week and number of doses per day. They are known as
blister packs and commonly
called bubble packs. However, these blister packs are filled in by hand. The
tablets are placed in the palm
CA 2921348 2020-03-10

of the hand and filled one by one into the designated slots increasing the
chances of contamination. The
blister packs are available as one-piece equivalent to a one-week supply.
There are increased chances of
error as the pills could be misplaced during the filling process. If a
patient's medication regimen is altered,
the entire blister pack has to be deblistered and refilled right from the
beginning. During the process of
filling the pills may be scattered or dropped on the floor thus increasing the
waste to the pharmacy and
polluting the environment. It is labour consuming as a technician or a
pharmacist has to fill the medications
one by one into each slot. Interruptions during the filling process increases
the chance of errors placing and
labelling the medications. Blister packs for a whole treatment such as weekly
or monthly treatment tend to
be large and require the somewhat tricky task of popping the blister to
retrieve multiple tablets, capsules or
the like. If one desires is out of the house when it is time for the dosage,
one must either skip the dose,
delay the dose or carry loose tablets until the dosage time.
In light of the above, there is still an unmet need to provide a more
convenient way for a patient to
self-administer medications provided to him/her while taking into account all
of the possible convenience
issues or changes in dosage which may occur during a treatment regimen.
SUMMARY OF THE INVENTION
According to a first aspect of the present invention, there is provided a
pharmaceutical formulation
dispenser comprising a rectangular array within which pouches filled with
medication are inserted for
dispensing medication to the patient at the appropriate time.
According to another aspect of the present invention, there is provided a
procedure to fill the
medication dispenser/pouch organizer. Preferably, each pouch is filled and
sealed prior to being inserted
into their respective compartments in the medication dispenser. Preferably,
this method is performed by a
machine. More preferably, the machine is programmable so as to be capable of
filing medication
pouches. Once the pouches are filled, they are placed into the appropriate
compartment on the medication
dispenser.
