Summary
Local anesthetics like bupivacaine show stereoselective effects on cardiac ion channels. Understanding these drug-receptor interactions is crucial for developing safer, more effective medications.
Area of Science:
- Pharmacology
- Molecular Biology
- Biophysics
Background:
- Local anesthetics are valuable tools for studying ion channel function and structure.
- Stereoselective interactions between drugs and biological targets highlight the asymmetric nature of cellular macromolecules.
- Many clinically used drugs are racemic mixtures, with enantiomers often exhibiting different pharmacokinetic and pharmacodynamic profiles, potentially leading to varied or adverse effects.
Purpose of the Study:
- To review the stereoselective effects of bupivacaine-like local anesthetics.
- To elucidate the three-dimensional relationships between local anesthetics and ion channels.
- To discuss the clinical implications of stereospecific drug-receptor interactions.
Main Methods:
- Review of existing literature on local anesthetic stereoselectivity.
- Analysis of studies investigating interactions with cardiac sodium and potassium channels.
Main Results:
- Bupivacaine-like local anesthetics exhibit stereoselective interactions with cardiac ion channels.
- These interactions reveal specific three-dimensional drug-channel relationships.
- Enantiomers can display distinct effects on channel function.
Conclusions:
- Stereoselectivity in local anesthetic action is a consequence of asymmetric biological systems.
- Understanding stereoselective effects is essential for predicting and managing drug actions.
- Identification of stereospecific interactions can guide the development of improved therapeutics.

01:23Local Anesthetics: Mechanism of Action
Local anesthetics (LAs) block sensory and motor impulses by inhibiting the sodium channels on the nerve cell membranes. This induces temporary loss of sensation, relieving pain in a specific body area.
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...

01:30Local Anesthetics: Chemistry and Structure-Activity Relationship
Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...
01:12Local Anesthetics: Adverse Effects
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

01:13Local Anesthetics: Pharmacokinetics
The potency and duration of action of local anesthetics (LAs) are determined by their pharmacokinetics. Pharmacokinetics describes how LAs are absorbed, distributed, metabolized, and eliminated from the body. When administered to the vascular tissues, LAs are quickly absorbed and enter the systemic circulation, reducing their localized effects. Adding vasoconstrictors such as epinephrine to LAs reduces their absorption into the systemic circulation, making them clinically effective. The...
01:24Local Anesthetics: Differential Sensitivity of Nerve Fibers
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
01:23Local Anesthetics: Common Agents and Their Applications
Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...
