Final answer:
Antibiotics are the main class of drugs used to cure septic shock, with newer antibiotics such as tigecycline designed to treat drug-resistant bacterial infections.
Step-by-step explanation:
The only class of drugs that can cure septic shock are antibiotics, as they address the underlying bacterial infection that causes the condition. Treatments for septic shock typically involve a combination of antibiotics and supportive care, such as intravenous fluids and medications to maintain blood pressure.
In resistant infections, the use of newer or more potent antibiotics, like tigecycline, is necessary. Tigecycline is designed to combat drug-resistant bacteria, which are often the causative agents in severe septic shock cases. However, there is no guaranteed cure, as certain factors like the bacteria's drug resistance and the patient's health condition greatly influence the outcome.
