Rapid Rx Quiz: Calcium-Channel Blockers

Rapid Rx Quiz: Calcium-Channel Blockers

Medscape29-05-2025
Calcium-channel blockers (CCBs) play a central role in the treatment of hypertension, angina, and certain cardiac arrhythmias and are among the most commonly prescribed drugs in the United States. Beyond their US Food and Drug Administration–approved uses, CCBs have found a place in treating several off-label conditions. With their widespread use, however, comes the responsibility of understanding their pharmacodynamics, drug-drug interactions, and potential toxicities.
How much do you know about CCBs? Test yourself with this short quiz.
Off-label uses for CCBs include Raynaud phenomenon, migraines, and subarachnoid hemorrhage. CCBs do not treat depression; in fact, their use has been associated with depression. Verapamil might reduce diastolic dysfunction, but this is not a mainstream use. The most common CCBs are relatively weight neutral.
Learn more about Raynaud phenomenon.
Including lightheadedness, specific adverse and serious adverse events from CCB use are bradycardia, constipation, headaches, flushing, worsening cardiac output, and peripheral edema, possibly from fluid redistributing from the intravascular space.

A recent study found that amlodipine was involved in the majority of overdose cases, accounting for 62% of all CCB overdoses. This far surpasses other agents such as lercanidipine (12%), diltiazem (11%), verapamil (10%), and felodipine (5%). The lower incidence of overdoses involving lercanidipine, diltiazem, verapamil, and felodipine corresponds with their declining presence in current hypertension treatment guidelines.
Although amlodipine is involved in more overdose cases overall, the study underscores that the severity of overdose varies significantly by CCB class. Nondihydropyridines, such as diltiazem and verapamil, were associated with markedly higher rates of life-threatening complications, including dysrhythmias (33-35% of cases) and intensive care unit (ICU) admissions (52% and 30%, respectively). In contrast, amlodipine showed much lower rates of dysrhythmias (1%) and ICU admissions (18%).
Learn more about CCB toxicity.
Many of the signs and symptoms of CCB toxicity are similar to normal CCB adverse events, making diagnosis challenging. A blood test can aid in diagnosis; abnormal findings that suggest CCB toxicity include acidosis, hyperglycemia, and hypokalemia. Neutrophilia has no established connection.

Combining diltiazem or verapamil with direct oral anticoagulants might increase risk for bleeding or clotting complications, though previous research has shown mixed results.
A recent study found no evidence of increased risk when direct oral anticoagulants were used alongside diltiazem or verapamil. However, patients who began direct oral anticoagulant therapy while already taking diltiazem had higher rates of overall mortality and cardiovascular-related death within 30 days, compared with those taking anticoagulants alone.

Caffeine craze warning after pouches gain in popularity with teens

While the use of caffeine pouches among teenagers remains relatively rare, experts and educators are concerned that may be about to change. Marketing aimed at teenagers of such products is spreading on social media. A school resource officer for the Boise County Sheriff's Office in Idaho, David Gomez, began noticing the use of caffeine pouches last spring, according to NBC News. The pouches can contain more than 200 milligrams of caffeine, and students have been using them along with nicotine pouches such as Zyn. Gomez noted that students would use the pouches as a disguise for nicotine pouches or they'll use both. 'They'll use the Zyn pouches that they put in their lip, and then they'll take a caffeine pouch,' said Gomez. 'They don't care what it is they're putting in their lip.' Richard Mumby is a marketing executive who was part of the launch of the e-cigarette Juul, which has been accused of initiating a wave of teen vaping. He's now back with a caffeine pouch startup known as Wip. A growing market is now trying to sell Americans on pouches as an alternative to caffeinated beverages. Mumby told NBC News that caffeine is part of 'the fabric of many Americans' everyday lives.' But he said there's room to improve. Wip and other companies are marketing caffeine pouches as a portable and affordable alternative to caffeinated drinks. It's a mix between nicotine pouches and energy drinks, placed between the lip and the gums to deliver the caffeine. Pouches, most of which do not contain nicotine, tend to last between 20 minutes and an hour, but their effect can go on for longer. Wip's flavors include mint, strawberry kiwi, and sour cherry, and each comes with 100 or 200 milligrams of caffeine, which is the same as about two cups of coffee. According to the U.S. Food and Drug Administration, that's half the amount of caffeine an adult can safely consume in an entire day. 'We take responsible caffeine consumption and responsible marketing of our product seriously,' a spokesperson for Wip told NBC News. 'While there are no legal age restrictions on caffeine products, we have adopted marketing guidelines that exceed the age-related standards set by the American Beverage Association for most common energy drinks. Wip is not intended for use by anyone under the age of 18, and our guidelines ensure the product is marketed responsibly.' Exercise and nutrition sciences professor at George Washington University's Milken Institute School of Public Health, Rob van Dam, studies caffeine. He shared concerns about the potency of some of the pouches being sold. 'It may be a bit different than coffee,' he told NBC News. 'It may hit faster, and you may overdose, in a way, more quickly.' Another worry is the possible popularity among teens, as nicotine pouches and energy drinks are already widespread. Zyn maker Philip Morris has previously told NBC News that 'Zyn's marketing is directed toward legal age nicotine users who are 21+.' The American Academy of Pediatrics has recommended that teens don't consume more than 100 milligrams of caffeine per day. The chair of the AAP's Committee on Nutrition, Dr. Mark Corkins, told NBC News that it would be better if teens avoided caffeine altogether. 'Caffeine, in general, is an area we are very concerned about,' he said. 'Pouches are just another delivery form.'

Weighted Vests: Are They Effective for Weight Loss?

With the ongoing obesity epidemic, researchers are constantly looking for strategies that optimize weight loss while minimizing associated side effects. One strategy currently gaining interest is the use of weighted vests— form-fitting garments into which weights are sewn or carried in pockets, enabling the wearer to add or remove them as needed. In theory, this offers a nonpharmacologic way to induce weight loss without the side effects of medications or weight-loss surgery, but with potential bone-sparing effects. The latter is important because even modest weight loss can reduce bone density and strength, increasing the risk for fracture. Weight loss — particularly when induced by caloric restriction — is associated with bone loss, especially at the hip. This is a consequence of loss of muscle mass and an unloading of bones from the decrease in body weight. Even modest diet-induced weight loss results in small but significant reductions in hip bone mineral density (BMD), with less consistent changes at the spine or whole body. These skeletal losses may increase fracture risk, particularly in older adults, and are more pronounced when weight loss occurs in the absence of exercise. Resistance training or combined aerobic-resistance exercise mitigate but do not fully prevent this bone loss. How Do Weighted Vests Help? Weighted vests can be used to preserve muscle mass during periods of caloric restriction. This is achieved by increasing gravitational loading and placing mechanical stress on weight-bearing tissues. Local fat mass is theoretically reduced by the work required to wear the weighted vest. Preservation of muscle mass has the dual benefit of preserving bone mass and maintaining resting metabolic rate (RMR). This is important because weight loss typically results in a lower RMR, which makes subsequent weight loss more difficult. Although using weighted vests does not lead to the same degree of weight loss reported with GLP-1 receptor agonists such as semaglutide, or GLP-1/glucose-dependent insulinotropic peptide (GIP) receptor agonists such as tirzepatide, the data demonstrate benefits of this strategy. For example, 5 weeks of high-load vest use (11% of body weight worn 8 hours per day) vs a low-load vest (1% of body weight) reduced fat mass and waist circumference with no significant change in overall body weight. Loss of fat mass and a reduction in waist circumference are not inconsequential outcomes. Fat distribution (particularly an excess of visceral fat with an increased waist circumference) is a major driver of many metabolic morbidities associated with obesity. In fact, newer definitions of preclinical and clinical obesity emphasize body fat distribution and waist circumference, rather than absolute body weight. The impact of weighted vest use on skeletal health is inconclusive at this time. Snow and colleagues reported preservation of hip BMD over a 5-year period in older, postmenopausal women when weighted vest use was combined with jumping exercises. However, a randomized controlled study from Wake Forest University (INVEST in Obesity) involving 150 older adults with obesity did not find a bone-protective effect of weighted vest use or resistance training following intentional weight loss. Further studies are needed to evaluate the impact on BMD of varying durations of vest use and varying weights of the vest. In conclusion, studies thus far have not demonstrated a significant impact of weighted vests for total weight reduction, although reductions in local fat mass and waist circumference may confer some metabolic benefit. These vests may provide mechanical stimuli that support musculoskeletal integrity; however, further research is necessary to prove this point and data available thus far are conflicting.
