Is there a difference between benzocaine and lidocaine?
Results: Twenty percent benzocaine did not significantly alter pain perception as measured by the pain rating score and visual analog scale with these 3 methods of stimulation. In contrast, 60% lidocaine significantly reduced pain perception according to these measurements.
Which is more potent procaine or lidocaine?
Results: Using the up-and-down methodology, the estimates of ED(50) for chloroprocaine was 0.1 ml of 1.2% (with 95% CI of 1.1-1.6), and that for lidocaine was 0.1 ml of 0.65% (with 95% CI of 0.65-0.88), giving a lidocaine/chloroprocaine potency ratio of 1.85 (with 95% CI of 1.66-2.61).
What is procaine made from?
Procaine is a benzoate ester, formally the result of esterification of 4-aminobenzoic acid with 2-diethylaminoethanol but formed experimentally by reaction of ethyl 4-aminobenzoate with 2-diethylaminoethanol.
Does lidocaine work better than benzocaine?
Lidocaine and benzocaine were equally efficient, and both were better than placebo in reducing pain caused by insertion of needles into the palate.
Does lidocaine last longer than benzocaine?
So, it’s hard to say which product type has the strongest delay effect if we can’t judge a specific benzocaine quantity. From my experience, lidocaine sprays are more effective than benzocaine products.
Why is procaine preferred over lignocaine?
However, procaine resulted in a lower overall quality of anesthesia and a prolonged average discharge time. If the shortfalls of procaine as studied can be overcome, it may provide a suitable alternative to lidocaine for outpatient spinal anesthesia to minimize the risk of TNS.
What is procaine used for?
Procaine is injected and used to numb pain. Taking procaine with succinylcholine can cause the numbing to last too long.
What are alternatives to lidocaine?
– Desipramine (Norpramin, Pertofrane) – Nortriptyline (Pamelor, Aventyl) – Protriptyline (Vivactil)
What is the difference between Carbocaine and lidocaine?
glucose-6-phosphate dehydrogenase (G6PD) deficiency.
What is the difference bewteeen HCl vs USP?

It is supplied as a white, capsule-shaped tablet for oral administration. Sotalol hydrochloride is a white, crystalline solid with a molecular weight of 308.8.
What is the difference between proparacaine and tetracaine?
What is the difference between Proparacaine and tetracaine? Proparacaine lasted 1.3 minutes longer than tetracaine, 10.7 minutes versus 9.4 minutes (p = 0.0001). CONCLUSION: Proparacaine eye drops cause less pain than tetracaine eye drops upon instillation. Anesthesia from proparacaine last slightly longer. These properties make proparacaine preferable to tetracaine.
