What is another name for articaine?

It was approved by the FDA in April 2000, and became available in the United States of America two months later under the brand name Septocaine, an anesthetic/vasoconstrictor combination with Epinephrine 1:100,000 (trade name Septodont).

What is the difference between articaine and Septocaine?

Articaine HCl has a partition coefficient in n-octanol/Soerensen buffer (pH 7.35) of 17 and a pKa of 7.8. SEPTOCAINE contains the following inactive ingredients: sodium chloride (1.6 mg/mL) and sodium metabisulfite (0.5 mg/mL). The product is formulated with a 15% overage of epinephrine.

What is articaine made from?

Articaine hydrochloride 4% and epinephrine 1:100,000 Septocaine® (articane hcl and epinephrine injection) contains articaine HCl (40 mg/mL), epinephrine (1:200,000 or 1:100,000) (as epinephrine bitartrate), sodium chloride (1.6 mg/mL), and sodium metabisulfite (0.5 mg/mL).

Is articaine stronger than lidocaine?

Articaine with a protein binding of 95 is greater than that of lidocaine at 65; this allows articaine to have a superior impact on duration of anaesthesia.

Can you mix articaine and lidocaine?

The combination of a higher dose of articaine, increased protein binding and increased lipid solubility may also provide a significant advantage over lidocaine in patients with local inflammation/infection which can make profound anesthesia more difficult to achieve.

Why is articaine more potent?

Articaine is different from other amide local anaesthetic because it contains a thiophene ring. The thiophene ring allows greater lipid solubility, which facilitates diffusion across the lipid-rich nerve membrane to access target receptors [9].

Is articaine more potent than mepivacaine for use in oral surgery?

Conclusions. Articaine is an effective anaesthetic with a rapid onset, comparable to mepivacaine in infiltrative techniques used for maxillary teeth extraction. However, articaine has clinically achieved faster dental anaesthesia and earlier teeth extraction than mepivacaine.

Why does articaine have the shortest half life?

Articaine has a serum half-life of 20–30 min, shorter than the other amide LAs due to the more rapid hydrolysis of the ester group within the plasma.

How do you mix local anesthetic?

Assuming you use regular 2% lidocaine and 0.5% bupivacaine and combine them 1:1, the concentration of each of these is halved. Therefore, you end up with 1% lidocaine and 0.25% bupivacaine in your mixture.

Why does articaine diffuse so well?

Articaine is another amide local anaesthetic solution that substitutes a thiophene ring for the benzene ring present in lidocaine. This modification allows articaine molecules to diffuse through nerve membranes more effectively than lidocaine molecules, due to increased lipid solubility.

Is articaine more toxic than lidocaine?

Articaine is 1.5 times as potent and only 0.6 times as toxic as lidocaine and has been shown to be superior in achieving successful anaesthesia following infiltration.

Can you mix Articaine and lidocaine?

How do you mix buffered lidocaine?

For practical purposes, we recommend mixing 10 mL of 1% lidocaine with 1:100,000 epinephrine with 1 mL of 8.4% sodium bicarbonate solution. Clarifying the proper mixture ratio is important because there have been many mixtures of different concentrations of lidocaine and bicarbonate advocated in the literature.

Does articaine contain Sulphur?

Articaine and Allergy As articaine possesses a sulfur-containing thiophene ring (Figure 1) this author is frequently asked if a patient having a sulfa, sulfite or sulfur allergy represents a contraindication to its administration.

Is articaine an amide or ester?

Articaine is an intermediate-potency, short-acting amide local anesthetic with a fast metabolism due to an ester group in its structure.

How is articaine metabolized?

Articaine is quickly metabolized via hydrolysis into its inactive metabolite articainic acid, which is partly metabolized in the kidney into articainic acid glucuronide (Figure 3). Metabolism of articaine into articainic acid and articainic acid glucoronide.

How do you dilute lidocaine hydrochloride?

Dilutions: →Lidocaine: Dilute the 2% (20 mg/ml) Lidocaine 1:4 to get final concentration of 0.5% (5 mg/ml) (for example: take 1 cc of Lidocaine and add 3 cc of Sterile, pyrogen-free water to an amber, sterile, multi-use vial).

Can lidocaine be diluted with normal saline?

Conclusion: Pain and discomfort during subcutaneous injection of lidocaine can be reduced by diluting the anesthetic with normal saline in a 1:10 ratio.

Which of the following local anesthetics is more water soluble?

Procaine local anesthetics
Procaine local anesthetics is more water-soluble.
