The reference material provided indicates that antivirals are medicines that clear viral infections.
Understanding Antivirals
Antivirals are a class of medicines specifically designed to combat viral infections. Unlike antibiotics, which target bacteria, antivirals work by interfering with the viral life cycle, preventing viruses from replicating and spreading within the body.
How Antivirals Work
- Stopping Viral Replication: Many antivirals work by stopping the virus from making copies of itself. This slows down the viral infection, allowing the body's immune system to catch up and clear the virus.
- Preventing Viral Entry and Exit: Some antivirals function by blocking viruses from entering host cells, thus preventing new infections. Others block the exit of new viral particles from infected cells, limiting the spread of the infection.
- Targeting Virus, Not Host: Most antivirals are developed to specifically target the virus and avoid causing harm to host cells, making them safer for the patient.
Key Aspects of Antiviral Treatment
Antiviral therapy is not a cure-all for viral infections; it is intended to alleviate the symptoms and reduce the severity and duration of infection. It also prevents the spread of the infection. Antiviral treatment strategies vary depending on the specific virus and patient conditions.
| Antiviral Action | Description |
|---|---|
| Replication Inhibition | Stops a virus from producing new viral particles. |
| Entry/Exit Blockage | Blocks viruses from entering or leaving cells, halting the spread. |
While antivirals are essential for treating viral infections, it is critical to note that the body's own immune system plays a critical role in clearing viruses. Antivirals support the immune system by reducing the viral load.
