How long does physostigmine take to work?
It will take 3 to 6 minutes for the central nervous system effect to become apparent. Some clinicians empirically pretreat with a benzodiazepine to prevent possible seizures. Because the half-life of physostigmine is 30 to 60 minutes, a repeated dose of 0.5 to 2 mg can also be given as clinically indicated.

Is Propofol a hazardous waste?
Results: Wasted or discarded propofol accounted for 45% of all the drug waste. Conclusions: Propofol does not degrade in nature, accumulates in body fat, and is toxic to aquatic life. We reduced wastage by removing 50 and 100 mL vials of propofol from the pharmacy, retaining only the smallest size (20 mL).
What is effects of physostigmine?
