SYN

BupivacaineN-2,6-(dimethyl)1-butyl-2-piperidincarboxamide (2.2.7), is chemically similar to mepivacaine and only differs in the replacement of the N-methyl substituent on the piperidine ring with an N-butyl substituent. There are also two suggested methods of synthesis. The first comes from α-picolin-2,6-xylidide (2.2.4). The alkylation of the last with butyl bromide gives the corresponding pyridine salt (2.2.6). Finally, it is reduced by hydrogen using platinum oxide as a catalyst into a piperidine derivative—bupivacaine [13,16].

The other method results directly from the piperidine-2-carboxylic acid chloride, which is reacted with 2,6-dimethylaniline. The resulting amide (2.2.8) is further alkylated with butyl bromide to bupivacaine [17–19].

Like lidocaine and mepivacaine, bupivacaine is used in infiltration, spinal, and epidural anesthesia in blocking nerve transmission. Its most distinctive property is its long-lasting action. It is used for surgical intervention in urology and in lower thoracic surgery from 3 to 5 h in length, and in abdominal surgery lasting from 45 to 60 min. It is used to block the trifacial nerve, the sacral and brachial plexuses, in resetting dislocations, in epidural anesthesia, and during Cesarian sections. The most common synonym for bupivacaine is marcaine.

3.7 Bupivacaine (21293) and Levobupivacaine (1976)

Bupivacaine (3.1.41) (Marcaine) is a local anesthetic of great potency and long duration that has been widely used for years, but it has cardio and CNS toxic sideeffects. For many years it was nearly the only local anesthetic applicable to almost all kinds of loco-regional anesthetic techniques, and nowadays, in many occasions, it is still the only alternative available [61–64].

Bupivacaine is currently used in racemic form. At high doses, however, the racemate is potentially hazardous due to toxicity problems.

Currently, racemic bupivacaine (3.1.41) is produced from picolinic acid (3.1.38) either by reduction to pipecolic acid (3.1.39) and then, after conversion to corresponding acid chloride (3.1.40) coupling with 2,6-xylidine to give pipecolic acid-2,6-xylidide (3.1.33), or by reducing the pyridyl amide (3.1.43) prepared from picolinic acid chloride (3.1.42) over platinum oxide. The amide intermediate (3.1.33), which can also be used to prepare the anesthetics ropivacaine (3.1.37) and mepivacaine (3.1.31), was transformed to desired bupivacaine (3.1.41) either by direct alkylation using butyl bromide and potassium carbonate or by reductive amination using butyraldehyde [45,59,65–69] (Scheme 3.7).

Enantiomers of bupivacaine can be prepared via diastereomeric salt resolution with tartaric acid or by resolution of the amide (3.1.33) with O,O-dibenzoyl tartaric acid followed by alkylation [47,70].

One of enantiomers, S(–) isomer of the racemic bupivacaine (levobupivacaine), has equal potency but less cardiotoxic and CNS effects in comparison with both R(+) bupivacaine and bupivacaine racemate. The reduced toxicity of levobupivacaine (3.1.48) gives a wider safety margin in clinical practice [71,72].

Stereospecific synthesis of levobupivacaine from (S)-lysine have been proposed (Scheme 3.8).

Treatment of N-CBZ (S)-lysine (3.1.44) with sodium nitrite in acetic acid yields the acetate (3.1.45). The prepared acetate (3.1.45) was then coupled with dimethyl aniline using N,N′-dicyclohexylcarbodiimide to give the amide (3.1.46) in good yield. The acetate group was then converted into the tosylate (3.1.47), which was deprotected and cyclized stereospecifically in one-pot reaction to give the amide (3.1.33) in high yield. Alkylation is easily achieved using an alkyl bromide and K2CO3 without any racemization. Alkylation can also be carried out using butyraldehyde/formic acid although the former is a much simpler process [73] (Scheme 3.8).

SYN

WO 9611181

Levobupivacaine has been obtained by two different ways: 1) The deamination of N-benzoyloxycarbonyl-L-lysine (I) with NaNO2/acetic acid gives 6-acetoxy-2(S)-(benzyl-oxycarbonylamino)hexanoic acid (II), which is amidated with 2,6-dimethylaniline (III) and dicyclohexylcarbodiimide (DCC) to the expected amide (IV). The deacetylation of (IV) with K2CO3 in methanol affords compound (V), which is tosylated as usual with tosyl chloride giving intermediate (VI), which is stereospecifically cyclized by means of K2CO3 in ethanol yielding N-(2,6-dimethyl-phenyl)piperidine-2 (S)-carboxamide (VII). Finally, this compound is alkylated with butyl bromide and K2CO3 or by reductoalkylation with butyraldehyde. 2) The amidation of piperidine-2-carboxylic acid (VIII) with 2,6-dimethylaniline (III) by means of SOCl2 in toluene gives the corresponding amide (IX), which is alkylated with butyl bromide as before yielding racemic bupivacaine (X) (3). This compound is then submitted to optical resolution by treatment with (S,S)-(?-tartaric acid followed by crystallization of the resulting tartrate and acidification with HCl in isopropanol.

SYN

Org Process Res Dev 2000,4(6),530

Improved yield in the synthesis of levobupivacaine. An improved yield in the synthesis of levobupivacaine can be obtained by recovering the unwanted (R)-enantiomer side product in the optical resolution of the racemic bupivacaine. The treatment of (R)-(I) with refluxing propionic acid causes its racemization, yielding racemic-(I) (bupivacaine), which is then submitted to a new optical resolution process using dibenzoyl-L-tartaric acid.

/////////////////////////////////////////////////////////////////////////////////////////////////////

Bupivacaine is a local anesthetic used in a wide variety of superficial and invasive procedures.

Bupivacaine, marketed under the brand name Marcaine among others, is a medication used to decrease feeling in a specific area.[4] In nerve blocks, it is injected around a nerve that supplies the area, or into the spinal canal’s epidural space.[4] It is available mixed with a small amount of epinephrine to increase the duration of its action.[4] It typically begins working within 15 minutes and lasts for 2 to 8 hours.[4][5]

Possible side effects include sleepiness, muscle twitching, ringing in the ears, changes in vision, low blood pressure, and an irregular heart rate.[4] Concerns exist that injecting it into a joint can cause problems with the cartilage.[4] Concentrated bupivacaine is not recommended for epidural freezing.[4] Epidural freezing may also increase the length of labor.[4] It is a local anaesthetic of the amide group.[4]

Bupivacaine was discovered in 1957.[6] It is on the World Health Organization’s List of Essential Medicines.[7] Bupivacaine is available as a generic medication.[4][8] An implantable formulation of bupivacaine (Xaracoll) was approved for medical use in the United States in August 2020.[9][10][11]

Medical uses

Bupivacaine is indicated for local infiltration, peripheral nerve block, sympathetic nerve block, and epidural and caudal blocks. It is sometimes used in combination with epinephrine to prevent systemic absorption and extend the duration of action. The 0.75% (most concentrated) formulation is used in retrobulbar block.[12] It is the most commonly used local anesthetic in epidural anesthesia during labor, as well as in postoperative pain management.[13] Liposomal formulations of bupivacaine (brand name EXPAREL) have shown to be more effective in providing pain relief than plain solutions of bupivacaine.[14][15]

The fixed-dose combination of bupivacaine with Type I collagen (brand name Xaracoll) is indicated for acute postsurgical analgesia (pain relief) for up to 24 hours in adults following open inguinal hernia repair.[10][11]

Bupivacaine (Posimir) is indicated in adults for administration into the subacromial space under direct arthroscopic visualization to produce post-surgical analgesia for up to 72 hours following arthroscopic subacromial decompression.[16][17]

Contraindications

Bupivacaine is contraindicated in patients with known hypersensitivity reactions to bupivacaine or amino-amide anesthetics. It is also contraindicated in obstetrical paracervical blocks and intravenous regional anaesthesia (Bier block) because of potential risk of tourniquet failure and systemic absorption of the drug and subsequent cardiac arrest. The 0.75% formulation is contraindicated in epidural anesthesia during labor because of the association with refractory cardiac arrest.[18]

Adverse effects

Compared to other local anaesthetics, bupivacaine is markedly cardiotoxic.[19] However, adverse drug reactions (ADRs) are rare when it is administered correctly. Most ADRs are caused by accelerated absorption from the injection site, unintentional intravascular injection, or slow metabolic degradation. However, allergic reactions can rarely occur.[18]

Clinically significant adverse events result from systemic absorption of bupivacaine and primarily involve the central nervous system (CNS) and cardiovascular system. CNS effects typically occur at lower blood plasma concentrations. Initially, cortical inhibitory pathways are selectively inhibited, causing symptoms of neuronal excitation. At higher plasma concentrations, both inhibitory and excitatory pathways are inhibited, causing CNS depression and potentially coma. Higher plasma concentrations also lead to cardiovascular effects, though cardiovascular collapse may also occur with low concentrations.[20] Adverse CNS effects may indicate impending cardiotoxicity and should be carefully monitored.[18]

Toxicity can also occur in the setting of subarachnoid injection during high spinal anesthesia. These effects include: paresthesiaparalysisapneahypoventilationfecal incontinence, and urinary incontinence. Additionally, bupivacaine can cause chondrolysis after continuous infusion into a joint space.[18]

Bupivacaine has caused several deaths when the epidural anaesthetic has been administered intravenously accidentally.[21]

Treatment of overdose

Further information: Lipid rescue

Animal evidence[22][23] indicates intralipid, a commonly available intravenous lipid emulsion, can be effective in treating severe cardiotoxicity secondary to local anaesthetic overdose, and human case reports of successful use in this way.[24][25] Plans to publicize this treatment more widely have been published.[26]

Pregnancy and lactation

Bupivacaine crosses the placenta and is a pregnancy category C drug. However, it is approved for use at term in obstetrical anesthesia. Bupivacaine is excreted in breast milk. Risks of discontinuing breast feeding versus discontinuing bupivacaine should be discussed with the patient.[18]

Postarthroscopic glenohumeral chondrolysis

Bupivacaine is toxic to cartilage and its intra-articular infusions may lead to postarthroscopic glenohumeral chondrolysis.[27]

Pharmacology

Pharmacodynamics

Bupivacaine binds to the intracellular portion of voltage-gated sodium channels and blocks sodium influx into nerve cells, which prevents depolarization. Without depolarization, no initiation or conduction of a pain signal can occur.

Pharmacokinetics

The rate of systemic absorption of bupivacaine and other local anesthetics is dependent upon the 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 preparation.[28]

  • Onset of action (route and dose-dependent): 1-17 min
  • Duration of action (route and dose-dependent): 2-9 hr
  • Half life: neonates, 8.1 hr, adults: 2.7 hr
  • Time to peak plasma concentration (for peripheral, epidural, or caudal block): 30-45 min
  • Protein binding: about 95%
  • Metabolism: hepatic
  • Excretion: renal (6% unchanged)[18]

Chemical structure

Like lidocaine, bupivacaine is an amino-amide anesthetic; the aromatic head and the hydrocarbon chain are linked by an amide bond rather than an ester as in earlier local anesthetics. As a result, the amino-amide anesthetics are more stable and less likely to cause allergic reactions. Unlike lidocaine, the terminal amino portion of bupivacaine (as well as mepivacaine, ropivacaine, and levobupivacaine) is contained within a piperidine ring; these agents are known as pipecholyl xylidines.[13]

Society and culture

Legal status

On 17 September 2020, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Exparel, intended for the treatment of post-operative pain.[29] The applicant for this medicinal product is Pacira Ireland Limited.[29] Exparel liposomal was approved for medical use in the European Union in November 2020.[30]

Economics

Bupivacaine is available as a generic medication.[4][8]

Research

Levobupivacaine is the (S)-(–)-enantiomer of bupivacaine, with a longer duration of action, producing less vasodilation. Durect Corporation is developing a biodegradable, controlled-release drug delivery system for after surgery. It has currently[when?] completed a phase-III clinical trial.[31]
