Yes, amlodipine tablets can be crushed. Amlodipine is an immediate-release tablet with no special coating or extended-release mechanism that would be compromised by crushing. The drug maintains its effectiveness whether swallowed whole, crushed, or taken as a liquid suspension.
Why Crushing Is Safe With Amlodipine
Not all medications can be crushed safely. Extended-release tablets, enteric-coated pills, and certain capsules rely on their physical structure to control how the drug enters your body. Crushing those can release too much medication at once, creating dangerous spikes in your bloodstream. Amlodipine doesn’t have any of these design features. It’s a plain, immediate-release tablet that dissolves in your stomach regardless of whether it arrives whole or as powder.
A bioavailability study in 20 healthy adults compared amlodipine tablets to a liquid suspension form and found no difference in how much drug the body absorbed. This confirms that the tablet’s shape isn’t doing anything special for absorption. Whether the drug reaches your stomach as a whole pill or as fine particles mixed into food, your body processes it the same way.
How to Crush and Take It
Use a pill crusher or place the tablet between two spoons to grind it into a fine powder. Mix the powder into a small amount of soft food like applesauce, yogurt, or pudding, and swallow the entire portion right away. You can also stir it into a small sip of water. The key is using a small enough amount of food or liquid that you consume all of it, so you get the full dose.
One thing to be aware of: crushed amlodipine tastes noticeably bitter. A taste-testing study with healthcare workers found that amlodipine ranked among the least palatable blood pressure medications when crushed, scoring poorly on a four-point acceptability scale. Mixing it with something flavored helps, but don’t be surprised if the taste still comes through. Taking a sip of juice or water immediately afterward can help clear the bitterness.
Splitting vs. Crushing
If you’re thinking about splitting amlodipine tablets in half rather than crushing them, that’s a different story. Standard amlodipine tablets are small and often unscored, which makes even splitting difficult. A study that tested tablets from five different manufacturers found that splitting unscored amlodipine tablets produced significant dose variability, with none of the split products meeting official content uniformity standards. The dose difference between halves ranged widely enough to matter clinically.
If you need a lower dose, crushing a whole tablet and measuring a portion isn’t reliable either. You’re better off asking your pharmacist about a lower-strength tablet (amlodipine comes in 2.5 mg, 5 mg, and 10 mg) or a liquid formulation that allows precise dosing.
Liquid Alternative: Katerzia
For people who consistently struggle with swallowing tablets, there’s an FDA-approved oral suspension called Katerzia. It contains 1 mg of amlodipine per milliliter, making it easy to measure exact doses with a syringe. It was specifically developed as a convenience dosage form for patients who have difficulty swallowing tablets, and it’s approved for adults and children six years and older.
Katerzia is a ready-to-use liquid, so no mixing or preparation is needed. For someone who crushes amlodipine every day, switching to the suspension can simplify the routine and eliminate the bitter taste problem. The tradeoff is cost: brand-name liquid formulations typically cost more than generic tablets, so check with your insurance or pharmacist about coverage.
Feeding Tube Administration
Crushed amlodipine can be given through a nasogastric or gastrostomy tube. Crush the tablet into a fine powder, dissolve it in a small volume of water, and flush the tube with water before and after administration to prevent clogging and ensure the full dose is delivered. The liquid suspension (Katerzia) is another option for tube feeding, since it eliminates the risk of undissolved particles blocking the tube.
Timing and Other Basics
Amlodipine is taken once daily, with or without food, and crushing doesn’t change this. Take your crushed dose at the same time each day. If you miss a dose, take it as soon as you remember, but skip it if more than 12 hours have passed since your usual time, then resume your normal schedule. Amlodipine has a long half-life, so a single missed dose won’t cause a sudden rebound in blood pressure, but consistent daily dosing keeps levels steady.
