Calcium Channel Blockers

Leave a Comment / Cardiology, Top 200 Drugs /
Calcium channel blockers (CCBs) are used in the treatment of many cardiovascular conditions. They are divided into subclasses, non-dihydropyridines and dihydropyridines. The non-dihydropyridine CCBs cause less vasodilation and more cardiac depression than dihydropyridine CCBs (hence why they are not recommended in decompensated heart failure). They cause reductions in heart rate and contractility. Dihydropyridine CCBs have more vascular selectivity and fewer cardiac effects. They are indicated in the treatment of hypertension and angina. They do not suppress AV conduction or the SA node automaticity.

Hypernatremia, Signs & Symptoms of

Leave a Comment / Critical Care /
🖇️ High levels of sodium can lead to a condition called hypernatremia, where the serum sodium concentration > 145 mEq/L (> 145 mmol/L). ⁠ ⁠ 🖇️ Sodium is a dominant cation in extracellular fluid and necessary for the maintenance of intravascular volume. When there is a large increase in sodium in the serum, the signs and symptoms often relate to fluids as you can see with today’s mnemonic.⁠ ⁠ 🖇️ The human body maintains sodium and water homeostasis by concentrating the urine secondary to the action of antidiuretic hormone (ADH) and increased fluid intake by a powerful thirst response.⁠

Monoamine Oxidase Inhibitor Side Effects

Leave a Comment / Psychiatry /
Monoamine Oxidase Inhibitors (MOA) are a class of antidepressants that includes Isocarboxazide (Marplan), Phenelzine (Nardil), Tranylcypromine (Parnate), and Selegiline (Emsam). ⁠ ⁠ MAO inhibitors are prone to drug interactions that inhibit its breakdown and could lead to hypertensive crisis, serotonin syndrome, or increased psychosis.⁠ ⁠ ⭐ Patients taking MAO inhibitors must avoid tyramine-rich foods, including aged cheese, pickled herring, yeast extract, air-dried meats, sauerkraut, soy sauce, fava beans, and some red wines and beers as it can precipitate hypertensive crisis. Foods can become high in tyramine when they have been aged, fermented, pickled, or smoked.⁠

Morphine Side Effects

Leave a Comment / Miscellaneous /
💊 Morphine is considered the classic opioid analgesic with which other painkillers are compared. Like other medications in this class, morphine has an affinity for delta, kappa, and mu-opioid receptors.⁠ ⁠ 💊 This drug produces the majority of its analgesic effects by binding to the mu-opioid receptor within the central nervous system (CNS) and the peripheral nervous system (PNS).⁠ ⁠ 💊 Morphine can potentially be a lethal medication when not used properly. It causes a host of symptoms related to depression of the CNS. Severe respiratory depression is the most feared complication of morphine in cases of overdose. Immediate injection of naloxone is required to reverse the effects of morphine.⁠

Proton pump inhibitors (PPIs) are one of the top 200 drugs prescribed (sometimes over-prescribed 😔) and are the strongest medications used to treat stomach acid disorders such as gastroesophageal reflux disease or peptic ulcers. ⁠⠀
⁠⠀
The generics in this class all end in “prazole”, however, if you pay close attention, the brand names of these drugs also hint at what they do. See below for some examples:⁠⠀
⁠⠀
💊 Prilosec (omeprazole): Pr (short for proton), lo (low), sec (secretions) meaning lowered secretions of protons (acid)⁠⠀
⁠⠀
💊 Aciphex (rabeprazole): aci (acid), phex (fix) which means it can help fix acid problems⁠⠀
⁠⠀
💊 Prevacid (lansoprazole): Prev (prevent) acid ⁠⠀
⁠⠀
💊 Protonix (pantoprazole): Proton (acid) nix (get rid of) or in other words nix protons⁠⠀

Respiratory Fluoroquinolones

Leave a Comment / Infectious Diseases /
Fluoroquinolones are highly effective antibiotics with many advantageous pharmacokinetic properties including high oral bioavailability, large volume of distribution, and broad-spectrum antimicrobial activity. Some antibiotics in this class include moxifloxacin, levofloxacin, and ciprofloxacin. ⁠⠀ ⁠⠀ 💊 Fluoroquinolones act by inhibiting two enzymes involved in bacterial DNA synthesis, both of which are DNA topoisomerases that human cells lack and that are essential for bacterial DNA replication, thereby enabling these agents to be both specific and bactericidal.⁠⠀

SNRI Side Effects

Leave a Comment / Psychiatry /
Serotonin and norepinephrine reuptake inhibitors (SNRIs) are a class of antidepressants that work by blocking serotonin and norepinephrine reuptake in the synapse (as the name suggests). ⁠ ⁠ 🗒️ It is important to educate patients that there is an increased risk of suicidal thinking and behavior in children, adolescents, and young adults during the first few months of therapy and it may take up to 8 weeks before therapeutic effects are recognized.⁠

SSRIs Side Effects

Leave a Comment / Psychiatry /
💊 Selective serotonin reuptake inhibitors (SSRIs) work by inhibiting 5-HT reuptake by the presynaptic cleft, thus increasing serotonin levels in the synapse.⁠ It is commonly used to treat depression, a condition thought to be linked to low levels of serotonin, dopamine, and norepinephrine. ⁠ ⁠ ⭐ As you can see, this mnemonic is similar to the mnemonic on the side effects of SNRIs. Since they both block serotonin reuptake, they exhibit very similar side effect profiles except SNRIs can also impact blood pressure (increase or decrease) due to the norepinephrine reuptake inhibition. SSRIs do not affect blood pressure. ⁠ ⁠ In addition, SSRIs can cause weight gain in adults on long-term therapy, while SNRIs cause less of this long-term weight gain and are more associated with weight loss. ⁠
