基本介绍
Chloroprocaine hydrochloride is a local anesthetic given by injection during surgical procedures and labor and delivery. Chloroprocaine, like other local anesthetics, blocks the generation and the conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse and by reducing the rate of rise of the action potential.

适应症
药理
| Indication | For the production of local anesthesia by infiltration and peripheral nerve block. They are not to be used for lumbar or caudal epidural anesthesia. | ||||||
| Pharmacodynamics | Chloroprocaine is an anesthetic agent indicated for production of local or regional anesthesia, particularly for oral surgery. Chloroprocaine (like cocaine) has the advantage of constricting blood vessels which reduces bleeding, unlike other local anesthetics like lidocaine. Chloroprocaine is an ester anesthetic. | ||||||
| Mechanism of action | Chloroprocaine acts mainly by inhibiting sodium influx through voltage gated sodium channels in the neuronal cell membrane of peripheral nerves. When the influx of sodium is interrupted, an action potential cannot arise and signal conduction is thus inhibited. The receptor site is thought to be located at the cytoplasmic (inner) portion of the sodium channel. It is hypothesized that Chloroprocaine binds or antagonizes the function of N-methyl-D-aspartate (NMDA) receptors as well as nicotinic acetylcholine receptors and the serotonin receptor-ion channel complex. | ||||||
| Absorption | The rate of systemic absorption of local anesthetic drugs is dependent upon the total dose and concentration of drug administered, the route of administration, the vascularity of the administration site, and the presence or absence of epinephrine in the anesthetic injection. | ||||||
| Volume of distribution | Not Available | ||||||
| Protein binding | Not Available | ||||||
| Metabolism |
Chloroprocaine is rapidly metabolized in plasma by hydrolysis of the ester linkage by pseudocholinesterase.

| Route of elimination | Chloroprocaine is rapidly metabolized in plasma by hydrolysis of the ester linkage by pseudocholinesterase. Urinary excretion is affected by urinary perfusion and factors affecting urinary pH. | ||||||
| Half life | 21 +/- 2 seconds | ||||||
| Clearance | Not Available | ||||||
| Toxicity | In mice, the intravenous LD50 of chloroprocaine HCl is 97 mg/kg and the subcutaneous LD50 of chloroprocaine HCl is 950 mg/kg. | ||||||
