Orabloc (Articaine Hydrochloride, Epinephrine)

Articaine blocks voltage‑gated sodium channels on nerve membranes, preventing the initiation and propagation of nerve impulses. This reversible inhibition stops pain signals from reaching the brain. The epinephrine component causes local vasoconstriction, which prolongs the anesthetic effect and reduces systemic absorption.

The specific dose of Orabloc is determined by the prescribing clinician based on the procedure, patient age, weight, and overall health. Only a qualified dental professional should calculate and administer the appropriate amount.

The safety of Orabloc in pregnancy and lactation has not been definitively established. It should be used only if the potential benefit justifies any potential risk to the fetus or infant, and after consultation with a healthcare provider.

To request Orabloc, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies, and procurement teams worldwide. After submission, the sales team will verify trade or institutional credentials and respond with pricing, availability, shipping details (including cold‑chain if needed), and required import documentation.

Orabloc contains articaine, which has a higher lipid solubility than many other amide anesthetics, allowing faster onset and deeper penetration. The added epinephrine provides prolonged duration and reduced bleeding. Compared with lidocaine, articaine may achieve comparable anesthesia with a lower total dose, but individual response varies.

Orabloc should be stored below 25 °C in its original packaging, protected from light and moisture. Do not freeze the solution. Keep the vial tightly sealed and avoid shaking vigorously before use.

Orabloc is administered by intraoral injection directly into the tissue surrounding the target tooth or surgical site. The clinician selects the appropriate injection technique (e.g., infiltration, block) and injects the calculated volume to achieve the desired anesthetic effect.

Serious risks include allergic reactions (including anaphylaxis), methemoglobinemia, seizures from excessive systemic absorption, cardiovascular events such as hypertension or arrhythmia, prolonged anesthesia, and rare cases of tissue necrosis at the injection site. Immediate medical attention is required if any of these occur.

Orabloc should be avoided in patients with known hypersensitivity to articaine, other amide‑type local anesthetics, or epinephrine. It is also contraindicated in individuals with uncontrolled hypertension, severe cardiac disease, or certain arrhythmias, and should be used with caution in pregnant or lactating women.
