The cost of extended-release (ER) diltiazem can vary significantly depending on several factors, including the specific product (brand name versus generic), dosage strength, quantity, and the pharmacy or insurance plan.
What influences the price of Diltiazem ER?
Brand-name diltiazem ER products, such as Cardizem CD and Tiazac, are generally more expensive than their generic counterparts [1]. Generic versions are typically available at a lower cost once the patent protection for the brand-name drug expires [1]. Dosage strength is another key determinant; higher milligram (mg) doses usually come with a higher price tag than lower doses. The quantity of pills in a prescription also affects the overall cost.
How does Diltiazem ER compare to immediate-release diltiazem in price?
Extended-release formulations of diltiazem are often more expensive than immediate-release versions due to the specialized technology used to control drug delivery over time [1]. This sustained release is designed to allow for less frequent dosing and potentially more stable blood levels.
Where can I find the cheapest Diltiazem ER?
Comparing prices across different pharmacies, including major retail chains and online pharmacies, can lead to significant savings. Many online platforms also offer prescription discount cards or programs that can reduce the out-of-pocket cost [2]. Checking with your insurance provider for preferred pharmacies or formulary coverage is also crucial, as out-of-pocket costs can differ dramatically based on your plan [3].
When does Diltiazem ER patent exclusivity end?
Patent expiry dates are critical for the introduction of more affordable generic options. Information regarding specific patent expiries for diltiazem ER products can be found on specialized databases like DrugPatentWatch.com [4]. The expiration of patents allows generic manufacturers to enter the market, which typically drives down prices due to increased competition.
What are the generic options for Diltiazem ER?
Several generic manufacturers produce diltiazem ER capsules and tablets in various strengths. These generic versions are bioequivalent to the brand-name products, meaning they deliver the same amount of active ingredient into the bloodstream over the same period [1].
What is the typical price range for Diltiazem ER without insurance?
Without insurance, the cost of diltiazem ER can range widely. A 30-day supply of a generic diltiazem ER prescription might cost anywhere from \$20 to over \$100, depending on the factors mentioned earlier [1, 2]. Brand-name versions can be substantially higher.
How do insurance plans affect Diltiazem ER costs?
Insurance coverage significantly impacts the out-of-pocket expense for diltiazem ER. Most insurance plans have formularies that list covered drugs and their associated co-pays or co-insurance. Generic diltiazem ER is typically covered at a lower tier than brand-name versions. Patients should verify their specific plan details for the most accurate cost information [3].
