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.
- Angiotensin II receptor blockers, also known as ‘sartans’, preferentially block the AT1 receptor subtype over the AT2 equivalent. ARBs are used in the treatment of hypertension, diabetic nephropathy and congestive heart failure.
- Mouth washing after inhaled corticosteroid use is effective for prevention of local adverse effects such as hoarseness and thrush.
- 5-HT3 receptor antagonists, also known as ‘setrons’, are used in the treatment and prevention of nausea and vomiting. They are not effective in the treatment of motion sickness.
- For the side effects of amiodarone, think of LEG PANIC – Liver enzyme fluctuations, Emesis, Gynecomastia, Pulmonary Fibrosis, Abnormal thyroid function, Nausea, Interstitial lung disease and Corneal microdeposits.
- Bisphosphonates, medicines used in the treatment of bone disorders such as osteoporosis and Paget’s disease, should be taken: in the morning, 30 minutes before any food or drink or medicines, and with a full glass of water. Examples of bisphosphonates include alendronic acid and zoledronate.
- Tetracyclines, the group of antibacterial drugs, are associated with tooth discolouration.
- A persistent, dry cough is associated with ACE inhibitors. Patients are sometimes then switched to angiotensin receptor blockers.
- Daptomycin is only effective against Gram-positive infections. In that regard, it’s used to treat skin and skin structure infections and aureus endocarditis.
- The NSAID, mefenamic acid, takes its name from its chemical structure, dimethylphenylaminobenzoic acid. It is used to treat mild-to-moderate pain, such as toothache and menstrual pain.
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.
