Plasma concentrations via this route peak within 2–4 hours. Intramuscular administration of lincosamides results in strong absorption, with peak plasma levels being reached in 1–2 hours. Around 90% of clindamycin is bound to plasma proteins, and is generally more stable and rapidly absorbed than lincomycin. [20]

[7] [8] A drug may be classified as second-line instead of first-line for one of three possible reasons: 1) it may be less effective than the first-line drugs (e.g., p-aminosalicylic acid), 2) it may have toxic side-effects (e.g., cycloserine), or 3) it may be effective, but unavailable in many developing countries (e.g., fluoroquinolones ...
Atipamezole is a veterinary drug whose prime purpose is to reverse the effects of the sedative dexmedetomidine (as well as its racemic mixture, medetomidine). [note 1] [9] [10] It can also be used to reverse the related sedative xylazine. [11]
