What is the active ingredient of Arestin?
(A.) Doxycycline hyclate
(B.) Chlorhexidine
(C.) Minocycline
(D.) All of the above combined
Answer: (C.) Minocycline
The following are some of the most commonly-used locally-applied antimicrobial agents, along with their active ingredients:
– Arestin – minocycline (a tetracycline antibiotic)
– Periochip – chlorhexidine
– Atridox – doxyclycline hyclate (a tetracycline antibiotic)
Arestin, Atridox, and Periochip are all placed in the deepest part of a diseased pocket and are left to dissolve on their own.
Note: Atridox and Arestin can be confusing. Let’s memorize “ARM” – “ARestin” is “Minocycline.” Then we know Atridox is made of the other antibacterial agent, doxycycline.
