Study Notes
Definitions of Key Terms
- Antibacterial: Refers to agents that combat bacteria, aiming to halt their growth or destroy them.
- Bactericidal: Class of antibacterial agents that actively kill bacteria rather than just inhibiting their growth.
- Broad spectrum: Antibiotics that are effective against a wide variety of bacterial species, targeting multiple types.
- Bacteriostatic: Agents that inhibit bacterial reproduction but do not kill them outright, allowing the immune system to eliminate the pathogens.
- Narrow spectrum: Antibiotics specifically designed to target a limited range of bacteria, often used for infections known to be caused by specific organisms.
- Anti-viral: Medications or treatments effective against viruses, designed to interfere with viral replication.
Antibiotics Mechanisms of Action
- Different classes of antibiotics (ABX) have varied mechanisms through which they exert their effects.
- Mechanisms can include inhibiting cell wall synthesis, protein synthesis, nucleic acid synthesis, or metabolic pathways.
General Side Effects of Antibacterial Preparations
- Hypersensitivity: Allergic reactions that can manifest as rashes or more severe symptoms.
- DRESS (Drug Rash with Eosinophilia and Systemic Symptoms): A severe reaction characterized by a rash, fever, and affected internal organs.
- Steven-Johnson Syndrome: A serious disorder where lesions appear on the skin and mucous membranes, potentially life-threatening.
- Super-infection: A secondary infection that occurs following the primary infection treatment, often due to disruption of normal flora.
- C-Difficile: An infection caused by Clostridium difficile that can happen due to antibiotic use, leading to severe diarrhea.
- Torsades de Pointes: A specific type of abnormal heart rhythm that can occur as a side effect of some antibiotics.
Eosinophilia
- Defined as an increased number of eosinophils in the blood, often associated with allergic responses or infections.
Contraindications for Selected Antibiotics
- Patients allergic to penicillin have a heightened risk of being allergic to related antibiotics, such as Cephalexin, due to cross-reactivity.
