Benzocaine
Chlorhexidine

Description

A surface anesthetic that acts by preventing transmission of impulses along nerve fibers and at nerve endings. [PubChem]

Indication

For general use as a lubricant and topical anesthetic on esophagus, larynx, mouth, nasal cavity, rectum, respiratory tract or trachea, urinary tract, vagina. It is also used to suppress gag reflex.

Mechanism of Action

Benzocaine binds to sodium channels and reversibly stabilizes the neuronal membrane which decreases its permeability to sodium ions. Depolarization of the neuronal membrane is inhibited thereby blocking the initiation and conduction of nerve impulses.

Toxicity

LD50=3040 mg/kg (rat, oral)

Description

A disinfectant and topical anti-infective agent used also as mouthwash to prevent oral plaque. [PubChem]

Indication

For reduction of pocket depth in patients with adult periodontitis, used as an adjunct to scaling and root planing procedures. Also for prevention of dental caries, oropharyngeal decontamination in critically ill patients, hand hygiene in health-care personnel, general skin cleanser, and catheter site preparation and care.

Mechanism of Action

Chlorhexidine's antimicrobial effects are associated with the attractions between chlorhexidine (cation) and negatively charged bacterial cells. After chlorhexidine is absorpted onto the organism's cell wall, it disrupts the integrity of the cell membrane and causes the leakage of intracellular components of the organisms.

Pharmacokinetics

Absorption
Absorption of chlorhexidine from the gastrointestinal tract is very poor. Additionally, an in vivo study in 18 adult patients found no detectable plasma or urine chlorhexidine concentrations following insertion of four periodontal implants under clinical conditions.
