A strong topical anesthetic for tattoos is a drug that numbs the area where it is applied. This minimizes pain and discomfort during minor surgeries and other procedures. Several drugs can be used as topical anesthetics. They include lidocaine, proparacaine, and tetracaine. The best drug for your needs will depend on the location of the pain, the type of procedure, and your personal preferences.
Topical anesthesia has been used in the world for two decades. Earlier, it was only available as an oral medication or via a patch. But the popularity of cosmetic and aesthetic surgery has led to renewed interest in topical anesthetics. There are now over 40 topical agents that have been studied. These compounds have various strengths and can be used for various medical conditions. Some of the most common are lidocaine, tetracaine, pramoxine, and bupivacaine.
Currently, topical anesthetics are available for use over the counter (OTC) or in prescription. But the safety of these products is still a concern. Some adverse effects have been reported, including numbness, discoloration, and swelling. Some of these side effects can be life-threatening. For example, when topical anesthetics are improperly applied, they can cause a seizure. They can also produce abnormal heart rhythms. So it is important to consult a doctor before using them.
Topical anesthesia is produced by directly applying local anesthetic solutions or ointments. These solutions can be enhanced by increasing their concentrations, free bases, or chemical permeation enhancers. During these treatments, the agent blocks the sodium channels of nerve cells. This decreases the permeability of the nerve cell membrane to sodium, reducing the membrane depolarization rate and increasing the threshold for electrical excitability.
Topical anesthetics are absorbed through the skin and mucous membranes. They are often used with antibiotics, anti-inflammatory, and dilating medications. They are effective in managing pain associated with lacerations and insect bites. However, there is a lack of data regarding the safety of using these drugs to treat wounds near the mucous membranes.
Topical anesthetics can also be a way to avoid injections. However, the problem with this method is that they are often difficult to apply to the upper lip. In addition, they can spread through the nerve sheaths, which can result in complications. To prevent this, doctors have to consider the pharmacology and dosage of these agents.
