Lidonostrum

Lidocaine, the active ingredient in Lidonostrum, is a local anesthetic presented as a topical formulation for cutaneous, nasal, oral and oromucosal use. It provides temporary loss of sensation to facilitate minor procedures or relieve localized pain on the skin and mucous membranes. GNH USA supplies Lidonostrum as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Lidonostrum is a local anesthetic that acts on peripheral nerve membranes to produce reversible loss of sensation. - Skin (cutaneous) anesthesia: provides temporary numbness for minor dermatologic procedures or pain relief on the skin. - Nasal mucosa anesthesia: numbs the nasal lining to facilitate endoscopic examinations or minor surgeries. - Oral and oromucosal anesthesia: creates localized numbness for dental work, oral surgeries, or relief of oral mucosal discomfort.

Lidocaine is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Burning or stinging at the application site - Itching or mild skin irritation - Redness or erythema - Swelling or edema of the treated area - Dry mouth or altered taste when used intra‑oral - Mild headache

Serious or Rare Side Effects: - Systemic toxicity (e.g., dizziness, seizures, cardiac arrhythmia) - Allergic reactions such as rash, urticaria, or angioedema - Methemoglobinemia, especially with extensive mucosal use - Severe skin reactions (e.g., Stevens‑Johnson syndrome) - Persistent numbness beyond the expected duration - Respiratory depression in cases of overdose

When using Lidonostrum, consider the following safety measures. - Allergy assessment: confirm no known hypersensitivity to lidocaine or other amide‑type anesthetics. - Application area: limit use to the intended surface and avoid excessive quantities. - Patient monitoring: observe for signs of systemic absorption, especially in children or patients with compromised skin integrity. - Drug interactions: review concomitant medications that may increase lidocaine plasma levels. - Storage: Store below 25°C: keep in the original packaging, protect from moisture and direct light.

Lidocaine may interact with other agents that affect cardiac conduction or sodium channel activity.

Major Interactions (Avoid): - Other local anesthetics: cumulative toxicity risk. - Class I antiarrhythmic drugs (e.g., quinidine, procainamide): may potentiate cardiac effects. - CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): can increase lidocaine plasma concentrations.

Moderate Interactions (Monitor Closely): - Beta‑blockers (e.g., propranolol): may enhance bradycardia. - Diuretics (e.g., furosemide): may alter electrolyte balance, affecting lidocaine activity. - Anticonvulsants (e.g., phenytoin): may modify seizure threshold when lidocaine systemic levels rise.
