Orabloc (Articaine Hydrochloride, Epinephrine)

Articaine blocks voltage‑gated sodium channels on nerve membranes, stopping the propagation of action potentials. This reversible inhibition prevents the nerves from transmitting pain signals. The epinephrine in the formulation constricts local blood vessels, extending the anesthetic effect and reducing bleeding.

The specific dose of Orabloc is determined by the prescribing dentist or oral surgeon based on the procedure, patient age, weight, and medical history. Only a qualified healthcare professional should decide the volume and concentration to be injected.

Safety data for Orabloc in pregnancy and lactation are limited, and the product is classified as having an unknown pregnancy category. Use is generally avoided unless the potential benefit justifies the potential risk, and it should be prescribed by a clinician familiar with the patient’s condition.

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.

Orabloc contains articaine, which has a higher lipid solubility than lidocaine, allowing faster onset and deeper penetration of dense bone. The added epinephrine prolongs its effect. Compared with other amide anesthetics, articaine may provide superior anesthesia for difficult extractions while maintaining a similar safety profile when used correctly.

Orabloc should be stored at room temperature, below 25 °C, in its original packaging. Protect the solution from direct sunlight, moisture and extreme temperature fluctuations. Do not freeze the product, and keep the vial tightly sealed when not in use.

Orabloc is supplied as a sterile solution for intraoral injection. The clinician injects the appropriate volume into the mucosal tissue or periodontal ligament using a standard dental syringe and needle, following aseptic technique and local anatomical guidelines.

Serious risks include allergic reactions such as anaphylaxis, cardiovascular events like severe hypertension or arrhythmia due to epinephrine, central nervous system toxicity leading to seizures, and rare cases of methemoglobinemia or tissue necrosis if inadvertently injected into a blood vessel.

Patients with a known hypersensitivity to articaine, other amide‑type local anesthetics, or epinephrine should avoid Orabloc. It is also contraindicated in individuals with uncontrolled hypertension, certain cardiac arrhythmias, or those taking non‑selective MAO inhibitors without appropriate medical supervision.
