The 31 pages that link to Local anesthetic, each with the reason it gives.

• NociceptionRelated: Local anesthetics interrupt nociceptive signals by blocking voltage-gated sodium channels in nerves.

• Voltage-gated sodium channelRelated: Many local anesthetics inhibit sodium channels and prevent action potentials.

• Trigeminal nerveRelated: Dental and facial procedures use these drugs to interrupt trigeminal sensation.

• NociceptorRelated: Local anesthetics suppress nociceptive signals by blocking voltage-gated sodium channels.

• AnalgesicBroader topic: Local anesthetics provide pain relief for procedures without requiring general unconsciousness.

• AnalgesiaBroader topic: It produces localized analgesia by preventing nerve impulses from traveling.

• EpinephrineRelated: Adding epinephrine can slow local anesthetic absorption and prolong its action.

• Opioid analgesicsCompared with: Local anesthetics suppress pain transmission without producing systemic opioid receptor effects.

• Topical medicationRelated: Its effect is defined by localized action, which topical anesthetics can produce at accessible sites.

• LidocaineNarrower topic: Lidocaine is widely used as an injectable, topical, and mucosal local anesthetic.

• Spinal anesthesiaRelated: These drugs interrupt sensory and motor signals after entering cerebrospinal fluid.

• Regional anesthesiaRelated: These drugs interrupt nerve signals to create regional sensory loss.

• TetrodotoxinCompared with: Like tetrodotoxin, local anesthetics inhibit sodium channels, but are used therapeutically.

• Saltatory conductionRelated: Blocking nodal sodium channels prevents action-potential regeneration.

• Inhalational anestheticCompared with: Its localized nerve blockade differs from inhaled drugs' production of general anesthesia.

• Local anesthetic systemic toxicityNarrower topic: LAST is a systemic adverse reaction to drugs ordinarily used to block sensation locally.

• Epidural anesthesiaRelated: These drugs provide the principal nerve block in many epidurals.

• Topical anestheticNarrower topic: Topical anesthetics are local anesthetics delivered across a body surface.

• Tropane alkaloidRelated: Cocaine was the first widely used local anesthetic and remains a notable tropane example.

• Alan HodgkinRelated: The sodium currents Hodgkin characterized are targets of drugs that interrupt nerve conduction.

• BenzocaineNarrower topic: Benzocaine belongs to this drug class and shares its core nerve-blocking action.

• Contraceptive implantRelated: Clinicians use it to numb the upper arm during insertion and removal.

• DentistryRelated: Local anesthesia enables many dental procedures while limiting pain.

• BatrachotoxinCompared with: Local anesthetics suppress sodium currents rather than forcing channels to remain open.

• Benzyl alcoholRelated: Benzyl alcohol has local anesthetic properties and is used in some medical formulations.

• BupivacaineNarrower topic: Bupivacaine is a long-acting member of this drug class.

• Depolarization (neuroscience)Related: Blocking sodium entry prevents the depolarization needed to propagate nerve impulses.

• ProcaineNarrower topic: Procaine is one member of this drug class.

• AnestheticBroader topic: Local anesthetics prevent pain without necessarily changing awareness.

• ChloroethaneNarrower topic: Chloroethane spray produced brief local numbness by rapidly cooling tissue.

• Throat lozengeNarrower topic: Some lozenges numb throat pain by temporarily blocking sensory nerves.
