Antibiotic Drugs Flashcards
These are substances that inhibit bacterial growth or kill bacteria and other microorganisms.
Antibacterial Drugs
He discovered the mold that produced Penicillin which was the first antibiotic to be sold and marketed,
Alexander Fleming
It is used with living tissues with lower potency and primarily inhibits growth (bacteriostatic).
Antiseptics
This is used with non-living things/objects, has a higher potency, and kills bacteria (bactericidal).
Disinfectant
It is the minimum amount of antibacterial drug to halt the growth of microorganisms.
MEC (Minimum Effective Concentration)
It happens when bacteria is sensitive to the drug.
The pathogen can be inhibited or destroyed.
It happens when bacteria is resistant to the drug.
The pathogen will continue to grow despite administration.
What are the two types of resistance:
- Inherent- it occurs without previous exposure to the drugs.
- Acquired- it is caused by prior exposure to the antibacterial.
This is used for Viral Infections, HIV / AIDS
- Antivirals
- Antiretrovirals
What are MDR-TB Medications (RIPES).
R- Rifampicin
I- Isoniazid
P- Pyrazinamide
E- Ethambutol
S- Streptomyacin
These are drugs used for Urinary Tract Infections.
- Sulfonamides
- Trimethropin
- Fluoroquinolones
- Antiseptics
These are 3 Antibiotic Effects for Antibiotic Combinations.
- Additive Effect- the effect equals the sum of two antibiotics.
- Potentiative Effect- occurs when one antibiotic increases the effect of the second drug.
- Antagonistic Effect- it happens when two drugs are used together, it may greatly reduce the desired effect.
It is a reaction to drugs that mild or severe.
Allergic reaction/ Hypersensitivity.
It is a secondary infection that occurs when the normal microbial flora of the body is disturbed during antibiotic therapy.
Superinfection
Here the liver and kidneys are involved in drug metabolism and excretion, and antibacterials may result damage to these organs.
Organ Toxicity
