Orabloc (Articaine Hydrochloride, Epinephrine)

Articaine works by reversibly blocking voltage‑gated sodium channels on nerve membranes, which stops the initiation and conduction of nerve impulses. The epinephrine component causes local blood‑vessel constriction, limiting systemic absorption and extending the duration of anesthesia at the injection site.

The exact dose of Orabloc is determined by the prescribing dentist based on the procedure, patient weight, and clinical judgment. Standard practice follows the maximum recommended articaine dose of 7 mg/kg, but the prescriber sets the final amount to ensure safety and efficacy.

Safety data for articaine in pregnancy are limited, and the product is classified as a category unknown. It should only be used when the potential benefit to the mother outweighs any possible risk to the fetus. Breastfeeding mothers should consult their healthcare provider before use.

To order Orabloc, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements), and necessary import documentation.

Both articaine (Orabloc) and lidocaine are amide‑type local anesthetics, but articaine has higher lipid solubility and a thiophene ring, which often results in faster onset and deeper penetration of bone. Consequently, articaine may be preferred for procedures requiring profound anesthesia, while lidocaine remains a widely used alternative.

Orabloc should be stored at ambient temperature, preferably below 25 °C. Keep the vial in its original packaging, protect it from direct light and moisture, and avoid freezing. Inspect the solution for clarity before use; discard if any particulate matter or discoloration is observed.

Orabloc is administered by intraoral injection. The clinician selects the appropriate technique—such as infiltration, nerve block, or periodontal ligament injection—based on the planned procedure. The solution is injected slowly to minimize tissue trauma and to achieve effective local anesthesia.

The most serious risks include severe allergic reactions (anaphylaxis), prolonged numbness or paresthesia, cardiovascular events such as tachycardia or hypertension due to epinephrine, and, rarely, seizures or cardiovascular collapse. Immediate medical attention is required if any of these events occur.

Orabloc should be avoided in patients with known hypersensitivity to articaine, other amide‑type anesthetics, or epinephrine. It is also contraindicated in individuals with uncontrolled hypertension, certain cardiac conditions, or those taking non‑selective MAO inhibitors. Clinicians must evaluate each patient’s medical history before administration.
