Take 60 seconds to review all the latest pharmacology facts released on our social media platforms over the past week. These are the essential, most fundamental facts that students who study medicines should commit to memory.
- Ivermectin is used to treat head lice, scabies, river blindness, and various other parasitic infections. Common side effects include dry and burning skin sensations, and red eyes.
- Sulfamethaxazole is often used in combination with trimethoprim, the resulting combination proving useful in the treatment of urinary tract infections, MRSA skin infections and lower respiratory tract infections, among other uses.
- Tetracycline antibacterial drugs interact with drugs or supplements that contain calcium or magnesium ions. Side effects include phototoxicity and tooth discolouration.
- Naloxone is used to reverse the effects of opioids, particularly in cases of opioid overdose. Side effects include sweating, nausea, restlessness, trembling, vomiting and headache.
- Rhabdomyolysis is a potential side effect of statins, drug used to lower cholesterol levels. Rhabdomyolysis is characterised by muscle damage, whose by-products can travel to the kidney to cause renal damage. It is a potentially fatal condition.
- Nifedipine is an L-type calcium channel blocker; a drug belonging to the dihydropyridine class. Grapefruit juice can increase its levels.
- Nifedipine is used to treat angina, hypertension, Reynaud’s phenomenon and premature labour. Side effects include faintness, headache, fatigue, cough, leg swelling.
- Fusidic acid is only effective against Gram-positive infections (skin infections); it inhibits bacterial translation (bacteriostatic).
- Antitussive drugs are medicines used to suppress cough, examples of which include codeine, pholcodine and dextromethorphan.
- Pica is an appetite disorder for substances that are non-nutritive - such as ice (pagophagia); hair (trichophagia); paper (papyrophagia).
- Pagophagia - the compulsive desire to consume ice/iced drinks - has been linked to iron deficiency anemia.
- Thalidomide is a teratogenic drug, meaning that it can cause birth defects. In the case of thalidomide, it can cause severe deformity of the body and limbs.
- Benzodiazepine withdrawal has, under certain circumstances, the capacity to cause seizures. This is particularly true, for example, in patients who suffer from seizures.
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.
