Vancomycin: A Video Presentation on Quality Use of Medicines

This assignment is a video presentation focusing on the antibiotic drug Vancomycin and its quality use in medicine. The presentation covers the pharmacokinetics of Vancomycin, including its administration, distribution, and excretion, as well as its mechanism of action, which involves binding to the cell wall of gram-positive bacteria to inhibit cell wall synthesis. It also addresses the importance of an interdisciplinary healthcare team in ensuring the safe and effective use of Vancomycin and emphasizes counseling considerations for patients, such as avoiding the medication if they have an infection and seeking immediate medical attention if they experience adverse effects. The presentation concludes by reinforcing the need for proper medication and safety from drug abuse, as well as the importance of following prescriptions.

INTRODUCTION
Vancomycin refers to an antibiotic drug that is effective in
several bacterial infections. It is recommended to use as
intravenously for the treatment of complicated
bloodstream infections,n endocarditis and skin infections.
It also includes help in meningitis and joint infections. It
has common side effects including allergic reactions and
pain at the site of injection. It can lead to creating hearing
loss, bone marrow separation, low blood pressure. In this,
there is a discussion about the description of the
pharmacokinetics of the drug.

Pharmacokinetics of drug
The pharmacokinetic profile of vancomycin is complex
and characterized through two or three compartments.
The pharmacokinetics profile includes drug administration
that can be done intravenously which includes the
standard infusion time which is about 1 hour to minimize
the adverse effect related with the infusion. Here,
creatinine clearance can be referred to as a good
predictor of Drug clearance from the system. Here, drug
distribution can be dependent on the amount of albumin
and it can be for protein binding along with total body
weight.

Conti...
It is poorly absorbed through the gastrointestinal tract
and about 60% of observation is there. Here volume of
distribution can vary between 0.4-1 L/kg 6. There is the
concentration of vancomycin with liver tissues and bile
after 24 hour of administration can be observed below
detection limits. Here, about 75 to 80 % of the drug gets
excreted through urine after the first 24 hour of
administration through glomerular filtration (Bishop and
et. al., 2018). There is no apparent metabolism of drug
(Antonoplis and et. al., 2019).

Mechanism of action
When drug reaches to the cell wall of the susceptible
gram-positive bacterium, here vancomycin get binds to
an acyl-D-ala-D-ala portion of the cell wall which is
growing. It prevents the cell wall after growing and form
cross-linking which helps to make it strong. Vancomycin
includes cell wall synthesis through binding to D-Ala-D-Ala
terminal which is a growing peptide chain during cell wall
synthesis.

Interdeciplinary team
Vancomycin drug belongs to part 4 The schedule of
schedule 4. Here, a healthcare professional who is
involved in providing healthcare services like a specialist
doctor, nursing staff and another staff member with other
specialty departments are some of the members of the
multidisciplinary team who work in coordination to ensure
the quality use of medicine for patient. Here, doctor and
specialists can prescribe the medicine to patients and
nursing staff can help to administer the medicine and
pharmacist can dispense it.

Counselling consideration
There is need to ensure that any individual with an
infection should avoid taking this medication. There is
also a need to ensure to get a check through doctor
immediately when getting any type of infection or fever,
harasses, side pain, lower back pain or difficult urination.
There is need to ensure about proper and better health
and need to also ensure to take instruction appropriately
about the administration of vancomycin.

CONCLUSION
From the above discussion, it can be concluded that when
Vancomycin is an antibiotic medication that can be used
for the treatment of bacterial infection. There is a need to
ensure the proper medication of vancomycin which can
create a side impact on individual health. There is also
need to ensure safety from drug abuse and should be
taken as per prescription. In this, there is a discussion
about the pharmacokinetics of vancomycin and how it's
drug bands to molecular targets.
