High Purity 99% Pain Killer Powder Procaine Powder Cas 59 46 1

It is less toxic and is one of the commonly used local anesthetics. This medicine is a short-acting ester local anesthetic with low lipophilicity and weak penetration into mucosa. Generally not used for topical anesthesia, local injection is often used for infiltration anesthesia, conduction anesthesia, subarachnoid anesthesia and epidural anesthesia. It takes effect 1-3min after the injection and can be maintained for 30-45min. After adding epinephrine, the maintenance time can be extended by 20%. Procaine can be hydrolyzed by esterases in plasma and converted into p-aminobenzoic acid (PABA) and diethylaminoethanol. The former can resist the antibacterial effect of sulfonamides, so it should be avoided at the same time with sulfonamides. Procaine can also be used to seal the injury site. Excessive use can cause central nervous system and cardiovascular reactions. Sometimes it can cause allergic reactions, so a skin allergy test should be done before medication, but allergic reactions can still occur if the skin test is negative. People who are allergic to this medicine can use chloroprocaine and lidocaine instead.
