Understanding how propranolol works helps pet owners know why vets prescribe it. It mainly targets the nervous system to reduce physical signs of anxiety.
Mechanism Of Action
Propranolol blocks certain receptors called beta-adrenergic receptors. These receptors respond to adrenaline, a hormone that causes the “fight or flight” reaction.
- Blocks beta-1 and beta-2 receptors in the body
- Reduces heart rate and blood pressure
- Limits adrenaline effects during stress
- Helps calm physical symptoms of anxiety like shaking or rapid breathing

| Effect | Description |
| Heart Rate | Slows down to reduce stress on the body |

| Stress Signals | Lessens the release of stress hormones |
