  • Bupivacaine Hcl Rx Only 0.5% with Epinephrine 1:200,000 (As Bitartrate) (Bupivacaine Hydrochloride and Epinephrine Injection, USP)
    Bupivacaine HCl Rx only 0.5% with epinephrine 1:200,000 (as bitartrate) (bupivacaine hydrochloride and epinephrine injection, USP) THIS SOLUTION IS INTENDED FOR DENTAL USE. DESCRIPTION Bupivacaine hydrochloride is (±) -1-Butyl-2´,6´-pipecoloxylidide monohydrochloride, monohydrate, a white crystalline powder that is freely soluble in 95 percent ethanol, soluble in water, and slightly soluble in chloroform or acetone. It has the following structural formula: Epinephrine is (-)-3,4-Dihydroxy-α-[(methylamino)methyl] benzyl alcohol. It has the following structural formula: BUPIVACAINE HCl is available in a sterile isotonic solution with epinephrine (as bitartrate) 1:200,000. Solutions of BUPIVACAINE HCl containing epinephrine may not be autoclaved. BUPIVACAINE HCl is related chemically and pharmacologically to the aminoacyl local anesthetics. It is a homologue of mepivacaine and is chemically related to lidocaine. All three of these anesthetics contain an amide linkage between the aromatic nucleus and the amino or piperidine group. They differ in this respect from the procaine-type local anesthetics, which have an ester linkage. CLINICAL PHARMACOLOGY BUPIVACAINE HCl stabilizes the neuronal membrane and prevents the initiation and transmission of nerve impulses, thereby effecting local anesthesia. The onset of action following dental injections is usually 2 to 10 minutes and anesthesia may last two or three times longer than lidocaine and mepivacaine for dental use, in many patients up to 7 hours. The duration of anesthetic effect is prolonged by the addition of epinephrine 1:200,000. It has also been noted that there is a period of analgesia that persists after the return of sensation, during which time the need for strong analgesic is reduced.

  • Local Anesthetics
    Local Anesthetics Introduction and History Cocaine is a naturally occurring compound indigenous to the Andes Mountains, West Indies, and Java. It was the first anesthetic to be discovered and is the only naturally occurring local anesthetic; all others are synthetically derived. Cocaine was introduced into Europe in the 1800s following its isolation from coca beans. Sigmund Freud, the noted Austrian psychoanalyst, used cocaine on his patients and became addicted through self-experimentation. In the latter half of the 1800s, interest in the drug became widespread, and many of cocaine's pharmacologic actions and adverse effects were elucidated during this time. In the 1880s, Koller introduced cocaine to the field of ophthalmology, and Hall introduced it to dentistry Overwiev Local anesthetics (LAs) are drugs that block the sensation of pain in the region where they are administered. LAs act by reversibly blocking the sodium channels of nerve fibers, thereby inhibiting the conduction of nerve impulses. Nerve fibers which carry pain sensation have the smallest diameter and are the first to be blocked by LAs. Loss of motor function and sensation of touch and pressure follow, depending on the duration of action and dose of the LA used. LAs can be infiltrated into skin/subcutaneous tissues to achieve local anesthesia or into the epidural/subarachnoid space to achieve regional anesthesia (e.g., spinal anesthesia, epidural anesthesia, etc.). Some LAs (lidocaine, prilocaine, tetracaine) are effective on topical application and are used before minor invasive procedures (venipuncture, bladder catheterization, endoscopy/laryngoscopy). LAs are divided into two groups based on their chemical structure. The amide group (lidocaine, prilocaine, mepivacaine, etc.) is safer and, hence, more commonly used in clinical practice.

  • Inhibitory Effects of Lappaconitine on the Neuronal Isoforms of Voltage-Gated Sodium Channels
    www.nature.com/aps ARTICLE Inhibitory effects of lappaconitine on the neuronal isoforms of voltage-gated sodium channels Yan-fen Li1,2, Yue-ming Zheng2,3, Yong Yu4, Yong Gan2,3 and Zhao-bing Gao2,3 Lappaconitine (LA) has been widely used for postoperative and cancer pain control. LA exhibits excellent analgesic activity with a longer effective time than common local anesthetics such as tetracaine and bupivacaine. However, the mechanisms underlying the featured analgesic activity of LA remain largely unknown. Here, we report that LA is an inhibitor of voltage-gated sodium channel 1.7 (Nav1.7) stably expressed in human embryonic kidney (HEK293) cells. LA inhibited Nav1.7 in a voltage-dependent manner with an IC50 value (with 95% confidence limits) of 27.67 (15.68–39.66) µmol/L when the cell was clamped at −70 mV. In comparison with the quick and reversible inhibition of Nav1.7 by tetracaine and bupivacaine, the inhibitory effect of LA was rather slow and irreversible. It took more than 10 min to achieve steady-state inhibition when LA (300 µmol/L) was administered. Unlike tetracaine and bupivacaine, LA affected neither the voltage-dependent activation nor the inactivation of the channels. Five residues in domain III and domain IV have been reported to be critical for the effects of the two local anesthetics on Nav channels. But our mutant study revealed that only two residues (F1737, N1742) located in domain IV were necessary for the inhibitory activity of LA. The slow onset, irreversibility, and lack of influence on channel activation and inactivation accompanied with the different molecular determinants suggest that LA may inhibit Nav1.7 channels in a manner different from local anesthetics.
