Each week we compile all the latest pharmacology facts released on our social media platforms. This is great pharmacology for students, as these facts are bite-sized, random, and often important facts that all students of medicine should commit to memory.
- Yohimbine is a drug used in veterinary medicine to reverse the effects of sedation in dogs.
- Methylphenidate (Ritalin) is a CNS stimulant used to treat ADHD and narcolepsy. It works as a norepinephrine-dopamine reuptake inhibitor.

- Extrapyramidal Symptoms II: Bradykinesia - slowness of movement, Tardive dyskinesia - jerky, irregular movements, Tremor - rhythmic twitching.
Mnemonics and mindmaps are also another great way to commit pharmacology to memory. But if you’d like to learn more about specific drug classes, check out these more detailed articles for more information.
