Characteristics of the substance Benzocaine

White crystalline powder odorless, slightly bitter taste; causes a feeling of numbness in the tongue. 1 g of benzocaine is soluble in 2500 ml of water, 5 ml of ethanol, 4 ml of ether, 2 ml of chloroform, in fatty oils (30 to 50 ml), in dilute hydrochloric acid. pKa 2.5. Molecular weight: 165.19.

Pharmacology

Pharmacological action - local anesthetic.

Reduces the permeability of the cell membrane for Na + ions, displaces Ca2 + from receptors located on the inner surface of the membrane, blocks the occurrence and conduct of nerve impulses. For local and oral use, absorption is minimal. When applied to mucous membranes, the effect develops within 1 minute and lasts 15-20 minutes.

Long-term studies in animals and humans to evaluate potential carcinogenicity and mutagenicity, as well as effects on fertility, have not been carried out.

Application of Benzocaine

Inside: gastralgia, esophagitis, peptic ulcer of the stomach and duodenum. Locally: acute inflammation of the middle ear, pain in the region of the external auditory canal, urticaria, skin diseases accompanied by itching; perianal cracks, hemorrhoids. Performing diagnostic manipulations on the mucous membranes (gastroscopy, rectoscopy, otoscopy, urethroscopy, gynecological procedures). In dentistry: superficial anesthesia.

Contraindications

Hypersensitivity.

Restrictions on the use

Children's age (up to 2 years).

Application in pregnancy and lactation

In pregnancy, use is only possible if necessary (it is not known whether benzocaine exerts harmful embryonic effects and effects on reproductive capacity).

The action category for fetus by FDA is C.

With caution in the period of breastfeeding (it is not known whether benzocaine penetrates into breast milk).

Side effects of Benzocaine

Contact dermatitis and / or hypersensitivity reactions (burning, tingling, itching, erythema, rash, urticaria, edema), persistent decrease in sensitivity at the site of application; rarely, with excessive use - methemoglobinemia (especially in infants and young children).

Interaction

Cholinesterase inhibitors inhibit the metabolism of benzocaine.

Overdose

Symptoms: methemoglobinemia, dyspnea, cyanosis, dizziness.

Treatment: symptomatic and / or injection of methylene blue.

Routes of administration

Inside, externally.
