Therapeutics and infections Flashcards
introduction of the model and general information about this topic
What is infection ?
The invasion and growth of organism in the body
Types of pathogen ?
Bacteria
Viruses
Fungi
Protozoa
treatment of :
- bacterial
- fungal
- viral
Bacterial:
–> antibiotic medication
Fungal:
–> Antifungal medication
Viral:
–> Non / antiviral medication
What is bacteria?
single-cell organisms without a nucleus
what is viruses
microscopic parasites that reproduce by taking over living cells
What is fungi
simple organisms that grow as single cells or thread like filaments
What is protozoa ?
Single cell organisms with a nucleus
Define selective toxicity
The ability of an antimicrobial drug to harm the target microbe without harming the host
What is drug resistance
is when the bacteria have a resistance strain from the antibiotics through natural selection and causing antibiotics to not have an effect on them
What is Pharmacokinetics
the principles to the safe and effective therapeutic management of drugs in an individual patient
What is Pharmacodynamics
How the drug affects the body
Which 4 principles are in the pharmacokinetics?
and what do they do?
A –> Absorption - how drug gets into the body
D –> Distribution - where drug goes to in the body
M –> Metabolism - how the body chemically modifies the drug
E –> Excretion - how the body gets rid of the drug
Examples of administration ? (give 5)
- Ocular delivery
- buccal delivery
- sublingual delivery
- oral delivery
- intravenous delivery
- intramuscular delivery
- subcutaneous delivery
- transdermal delivery
- pulmonary/ nasal delivery
- vaginal/ rectal delivery
what is drug absorption
the process of drug movement from site of administration towards the bloodstream
How fast will the absorption occurs?
it depends on the method of administration as it varies in different speeds
