Pharmacology Facts (11-16 September)

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.

If you haven’t already, be sure to check out our Facebook and Twitter feeds for all the latest articles, infographics, and facts. These facts were released during the period 11-16 September.

  • 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.
  • Routes of Administration: Intrathecal route - inj. into spinal cord, Intracavernous - inj. into the base of the penis.
  • Laudanum is a tincture of 10 percent opium by weight (1 percent morphine). It was historically used as an analgesic and cough suppressant.

  • Extrapyramidal symptoms are drug-induced movement disorders. Commonly caused by 'typical' antipsychotics that antagonize D2 receptors.
  • Trihexyphenidyl is an antimuscarinic that treats Parkinson's; it can also be used to alleviate extrapyramidal effects caused by antipsychotics.
  • Extrapyramidal Symptoms I: Dystonia - continuous spasms/muscle contractions, Akathisia - motor restlessness, Parkinsonism – rigidity.
  • 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.
