Procaine: A Comprehensive Review
Abstract
Procaine is an ester local anesthetic that is commonly used in clinical practice for pain relief and local anesthesia. This review article provides an overview of procaine, its history, pharmacological properties, clinical applications, adverse effects, and other considerations. The main goal of this review is to provide a comprehensive summary of the current knowledge and understanding of procaine so that clinicians may make informed decisions when considering its use in clinical practice.
Introduction
Procaine is a commonly used local anesthetic that has been used in clinical practice since its development in 1905. It is a member of the ester class of local anesthetics and is used to produce local and regional anesthesia. It is also used for intravenous regional anesthesia, dental and ophthalmic anesthesia, and infiltration anesthesia. In addition to its anesthetic properties, procaine has been used to treat a variety of medical conditions including pain relief, wound healing, and treatment of some neurological and cardiovascular diseases. The purpose of this review article is to provide a comprehensive overview of procaine, its pharmacological properties, clinical uses, adverse effects, and other considerations.
History
Procaine was developed in 1905 by Alfred Einhorn and is the first ester-type local anesthetic to be developed. It is an ester of para-aminobenzoic acid and was initially used as a substitute for cocaine in medical applications. It was soon found to be useful for local anesthesia and was widely used in dentistry and other medical procedures. In the 1950s, procaine was replaced by safer and more effective local anesthetics, such as lidocaine and bupivacaine. It is still used in some clinical applications due to its low cost and ease of use.
Pharmacological Properties
Procaine is a water-soluble ester local anesthetic with a short duration of action. It is rapidly metabolized by hydrolysis in the liver, and its active metabolite, PABA, is then excreted in the urine. The most common route of administration is by injection, and procaine can be administered topically, intramuscularly, or intravenously.
Clinical Uses
Procaine is used for a variety of clinical applications, including:
• Dental anesthesia
• Ophthalmic anesthesia
• Infiltration anesthesia
• Intravenous regional anesthesia
• Pain relief
• Wound healing
• Treatment of some neurological and cardiovascular diseases
Adverse Effects
Procaine is generally safe and well tolerated when used at recommended doses. Common side effects may include pain and stinging at the injection site, dizziness, and nausea. There is also a risk of allergic reaction to the drug, which may include rash, itching, and difficulty breathing. Rarely, procaine can cause serious adverse effects such as anaphylaxis, cardiac arrhythmias, and seizures.
Other Considerations
Procaine is contraindicated in patients with known allergy to the drug. It should also be used with caution in patients with a history of heart disease, liver or kidney disease, or epilepsy. Procaine is not recommended for use in pregnant or breastfeeding women.
Conclusion
Procaine is an ester local anesthetic that has been used in clinical practice for over a century. It is used to produce local and regional anesthesia, pain relief, and wound healing. It is generally safe and well tolerated when used at recommended doses, but there is a risk of serious adverse effects. Clinicians should consider the potential risks and benefits when considering its use in clinical practice.
