Lidonostrum

Lidocaine, the active ingredient in Lidonostrum, is a local anesthetic presented as a topical formulation for cutaneous, nasal, oral, or oromucosal use. It provides temporary numbing of surface tissues in adults and children as directed by a healthcare professional.

GNH USA supplies Lidonostrum as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Lidocaine is used to achieve local anesthesia in various superficial tissues and mucous membranes.

- Minor skin procedures: provides rapid surface numbness for suturing, biopsies, or laser treatment. - Oral or oropharyngeal discomfort: relieves pain from aphthous ulcers, sore throat, or dental procedures. - Nasal procedures: numbs nasal mucosa for endoscopic examinations or minor surgeries.

Lidocaine can cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects: - Burning or stinging at the application site. - Redness or mild swelling of the skin or mucosa. - Nausea or mild dizziness. - Headache. - Temporary taste alteration when used orally.

Serious or Rare Side Effects: - Systemic toxicity presenting as seizures, cardiac arrhythmias, or profound hypotension. - Allergic reactions such as rash, itching, or angioedema. - Methemoglobinemia, especially with extensive mucosal use. - Persistent numbness beyond the expected duration. - Severe local tissue irritation or ulceration.

When using lidocaine, consider the following safety measures.

- Dosage limits: adhere to recommended maximum amounts to avoid systemic toxicity. - Application area: avoid use on large surface areas or broken skin unless directed. - Concomitant anesthetics: do not combine with other topical anesthetics without professional guidance. - Medical history: assess for cardiac, hepatic, or renal impairment before use. - Pediatric use: adjust amount according to weight and age under medical supervision. - Store at ambient temperature: keep in the original container, protect from moisture and heat.

Lidocaine may interact with other substances that affect cardiac conduction or metabolism.

Major Interactions (Avoid): - Class I antiarrhythmics (e.g., quinidine, procainamide): additive cardiac conduction effects. - CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): may increase lidocaine plasma levels.

Moderate Interactions (Monitor Closely): - Beta‑blockers: potential for enhanced bradycardia. - Other local anesthetics: risk of cumulative toxicity. - Monoamine oxidase inhibitors: may alter hemodynamic response.
