| Anestetic | treatment for pain with loss of consciousness |
| 3 types of anesthetics | local, regional, general |
| local anesthetics | blocks nerve conduction in a localized areaMOA sodium ions are blocked from entering nerve membranesTU dental procedures |
| 2 types of local anesthetics | Esters/benzocaine-Ora-gel prepsAmides/lidocaine-xylocaine |
| regional anesthetics | give into a specific area eg:spinal cord or epideralTU: childbirth, dental procedures |
| General anesthetics | produce loss of consciousness with no response to pain (day surgury) |

| 2 types of depression | unipolar- just depressedbipolar- depressed with episodes of mania |
| drugs to treat depression | Tricyclics MOA- block reuptake to NE and 5HT therefore leaving increased levels at the synapseamitriptyline-elavilclomipramine-anafranil |
