Orabloc (Articaine Hydrochloride, Epinephrine)

Articaine hydrochloride, the active ingredient in Orabloc, is a local anesthetic (amide) presented as a dental injection for local administration use. It provides reversible inhibition of neuronal sodium channels and is combined with epinephrine to achieve prolonged anesthesia for dental procedures. GNH USA supplies Orabloc as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Orabloc, a dental local anesthetic, is used to achieve numbness in oral tissues during various procedures. - Tooth extraction: provides profound local anesthesia to facilitate painless removal of teeth. - Restorative dentistry: enables comfortable placement of fillings, crowns, and bridges. - Periodontal surgery: allows effective pain control during gum grafts, pocket reduction, and other periodontal interventions.

Common Side Effects: - Transient numbness or tingling at the injection site. - Mild pain or pressure sensation during injection. - Local bruising or swelling. - Headache. - Metallic taste. - Temporary lip or tongue numbness.

Serious or Rare Side Effects: - Allergic reaction (rash, itching, swelling, anaphylaxis). - Seizures or convulsions. - Cardiac arrhythmias or hypertension due to epinephrine. - Prolonged soft‑tissue anesthesia. - Methemoglobinemia (rare).

Before administration, consider the following precautions: - Allergy assessment: verify no known hypersensitivity to amide‑type anesthetics or epinephrine. - Cardiovascular status: use caution in patients with uncontrolled hypertension or significant cardiac disease. - Drug interactions: review concurrent use of non‑selective beta‑blockers or MAO inhibitors. - Pregnancy and lactation: evaluate risk‑benefit ratio; limited data are available. - Pediatric use: adjust dose according to weight and clinical need. - Store at ambient temperature: keep below 25 °C, protect from moisture and direct sunlight.

Artabloc may interact with several medication classes. Major Interactions (Avoid): - Non‑selective beta‑blockers: may potentiate epinephrine‑induced hypertension. - Monoamine oxidase inhibitors (MAOIs): increased risk of hypertensive crisis. - Tricyclic antidepressants: may enhance cardiovascular effects of epinephrine.

Moderate Interactions (Monitor Closely): - Other local anesthetics: cumulative toxicity risk. - Antihypertensive agents (e.g., clonidine): may blunt epinephrine response. - Sympathomimetic drugs: additive cardiovascular stimulation.
