Antimicrobial Therapy Introduction Flashcards
High molecular weight proteins and peptides have to be administer from which route
Intravenous
Which route enables fast absorption for all solutions
IV
Which route is not suitable for big volume injections
Subcutaneous
Which substances should not be given by Subcutaneous route
Irritant substances
Cytotoxic drugs
Subcutaneous route enables fast and slow absorption for which solutions
Fast= aqueous
Slow= poorly soluble
Intramuscular route enables fast and slow absorption for which solutions
Fast= aqueous solutions
Slow and consistent= depot solutions
When Intramuscular route should be avoided
In patients with anticoagulant use
Which route is the most convenient,safe and economic
Oral
Most common drugs whose initial symptoms begin after more than 4 hours
Acetaminophen
Aspirin
Classification of untoward drug reactions
Desirable (therapeutic)
Undesirable —> Non-deleterious and Deleterious
Deleterious—> Pharmacological, Pathological,Genotoxic
Pharmacological Toxicity
Dose dependent effects of a drug over certain functions
Pathological Toxicity
Drug induced pathological tissue damage that is generally associated with high doses
When Necrosis or cell death happens
Genotoxicity
Situations in which drugs cause DNA damage
Dose independent reactions
Allergic reactions
Idiosyncratic reactions
Type of allergic drug reactions
Anaphylactic reactions —humoral
Cytolitic reactions —humoral
Arthus reactions —humoral
Delayed hypersensitivity —cellular
Anaphylactic reactions caused by
The release of high concentration of histamine, prostaglandins, Leukotrienes
Anaphylactic reactions mediated by
IgE
Anaphylactic reactions causes
Vasodilation
Hypotension
Edema
Inflammatory response
Which allergic reaction is the Fastest allergic response
Anaphylactic reactions
Cytolitic reactions caused by
Direct toxicity of ab for a certain ag in host tissues following ab tissue binding
Targets of Cytolitic reactions
Constituents of haematological system
Arthus reactions caused by
Precipitated ag-ab complexes
Delayed hypersensitivity caused by
Cellular immune system components like macrophages and T cells
Drug Investigation phases are composed of?
Phase 0—> preclinic
Phase 1—> healthy volunteers
Phase 2—> volunteer patients
Phase 3—> control groups
Phase 4—> post marketing
Toxidrome
Syndrome that is the constellation of signs and symptoms following intoxication of a substance
Why is Therapeutic index is important
For safety
Minimal inhibitory concentration
Minimum concentration of drug to inhibit visible growth of microorganisms in the culture
Important in deciding whether the microorganism is susceptible or resistant to the drug tested.
Types of Antimicrobial therapy
Prophylaxis
Pre-emotive
Empiric
Definitive
Suppressive
Prophylactic treatment
Done before the infection for prevention
Vaccination
Pre-emptive treatment
There is infection but in incubation period
No symptoms
Curative treatment
Empiric= ın the absence of complete or perfect info
Definitive= after the knowledge of the microbe
Symptoms are seen
Suppressive treatment
Taking daily treatment after the acknowledgment of the infection and the microorganism
Inhibition of viral DNA polymerase done by which drugs
Acyclovir
Vidarabine
Foscarnet
Ganciclovir
Influenza complete its replication at
Host cell nucleus
**exception, others complete it at the cytoplasm
Nucleoside analogues that need viral enzyme for activation
Acyclovir
Valacyclovir
Ganciclovir
Valganciclovir
Nucleoside analogues that does not need viral enzyme for activation
Cidofovir
Which nucleoside analogue does not need viral enzyme for activation
Cidofovir
Non-nucleoside analogues drugs that does not need viral enzyme for activation
Foscarnet
Role of Hemagglutinin and Neuroaminidase in İnfluenza replication
Hemagglutinin in uncoating M2, binding to cell surface
Neuroaminidase in release from the cel
Anti influenza agents
Amantadin
Rimantadin
Oseltamivir
Viral target for amantidin
Influenza M protein
