The product is soluble in alcohol, ether, benzene, chloroform and oils, according to the chemicals encyclopedia published by the Royal Society of Chemistry , 14th ed. online (2006). Lidocaine hydrochloride monohydrate (Product No. L5647) is soluble in water. Since the lidocaine hydrochloride is so much more soluble than lidocaine free base, lowering the pH to that of the hydrochloride (pH 4.0-5.5) or to that of injectable forms (pH 5.0-7.0) should greatly enhance the solubility of L7757.

General description
Biochem/physiol Actions
Lidocaine, a neuroprotective agent, mediates blockage of sodium (Na+) channels.[2][4] It prevents the influx of sodium ions leading to depolarization of sodium channels[3] and metabolically inactivated in liver.[4] Lidocaine has positive effect on cerebral ischemia.[2] It is also used in the treatment of ventricular tachycardia.[4] Lidocaine is an efficient anesthetic agent in ophthalmic surgeries as it is highly potent and has good tissue penetrability.[7]
Na+ channel blocker; class IB antiarrhythmic that is rapidly absorbed after parenteral administration.

How does the storage temperature relate to shipping conditions?
1 answer-
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment.
