Definition

Cinchocaine is a monocarboxylic acid amide that is the 2-(diethylamino)ethyl amide of 2-butoxyquinoline-4-carboxylic acid. One of the most potent and toxic of the long-acting local anesthetics, its parenteral use was restricted to spinal anesthesia. It is now generally only used (usually as the hydrochloride) in creams and ointments and in suppositories for temporary relief of pain and itching associated with skin and anorectal conditions. It has a role as a topical anesthetic. It is a monocarboxylic acid amide, a tertiary amine compound, and an aromatic ether.

Cinchocaine hydrochloride is the monohydrochloride salt of cinchocaine. It is used in creams, ointments, and suppositories for temporary relief of pain and itching associated with skin and anorectal conditions. It contains a cinchocaine.

Mechanism of Action of Cinchocaine

Local anesthetics block both the initiation and conduction of nerve impulses by decreasing the neuronal membrane’s permeability to sodium ions through sodium channel inhibition. This reversibly stabilizes the membrane and inhibits depolarization, resulting in the failure of a propagated action potential and subsequent conduction blockade.

Indications of Cinchocaine

  • For the production of local or regional anesthesia by infiltration techniques such as percutaneous injection and intravenous regional anesthesia by peripheral nerve block techniques such as brachial plexus and intercostal and by central neural techniques such as lumbar and caudal epidural blocks.
  • The monohydrochloride salt of cinchocaine. It is used in creams, ointments, and suppositories for temporary relief of pain and itching associated with skin and anorectal conditions.
  • Topical anesthetics are indicated to relieve pain, pruritus, and infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation associated with minor skin disorders, including burns, minor, including sunburn; bites (or stings), insect; dermatitis, contact, including poison ivy, poison oak, or poison sumac; wounds, minor such as cuts and scratches.
  • Epidural anesthesia can be performed in the sacral hiatus (caudal anesthesia) or in the lumbar, thoracic, or cervical regions of the spine.
  • Cinchocaine is the active ingredient in some topical hemorrhoid creams such as Proctosedyl. It is also a component of the veterinary drug Somulose, used for euthanasia of horses and cattle.
  • Hemorrhoids
  • Pruritis of the skin
  • Pruritus Ani
  • Skin Irritation

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

Rural patient practical tips
