blistering, peeling, or loosening of the skin
bloating
blurred or change in vision
Mech of Action for doxorubicin
- interacts with DNA to slow or stop growth of cancerous cells by blocking the enzyme topo-isomerase 2
Mech of action for quinolones
- Quinolone antibiotics destroy bacteria by altering their DNA. They accomplish this by interfering with the bacterial enzymes DNA gyrase and topo-isomerase IV. The quinolones kill susceptible strains of bacteria
Prophylactic therapy
antibiotics taken before anticipated exposure to infectious organism in an effort to prevent development of infection
Adverse effects of Influenza Vaccine:
Soreness, redness, and/or swelling from the shot
Headache

Definition of Toxoid
It is a bacterial exotoxins (which is a toxin secreted by bacteria) that has been inactivated by exposure to a harsh chemical or heat which then suppresses their effectiveness. But although they’ve become inactive, they can still bind to host B cells and form antitoxin.
They are used in vaccines because they induce an immune response to the original toxin. Example is tetanus toxoid, which is the most often used.
