Formula Information

A small arrow pointing down

Diltiazem HCl 20 mg/ml Oral Liquid is a custom-prepared medication designed for ease of administration and precise dosing. This formulation is particularly beneficial for patients who have difficulty swallowing pills, such as those in pediatric and geriatric populations, or for those with conditions affecting the esophagus or swallowing reflex. The liquid form allows for flexible dosing, which can be adjusted according to the specific needs of the patient.

Diltiazem is a calcium channel blocker that works by relaxing the muscles of the heart and blood vessels. It is commonly used to treat hypertension (high blood pressure), angina (chest pain), and certain heart rhythm disorders. By dilating blood vessels and reducing the workload on the heart, diltiazem helps to lower blood pressure, increase the supply of blood and oxygen to the heart, and prevent angina attacks. This oral liquid formulation ensures that patients who are unable to take solid forms of medication can still receive the therapeutic benefits of diltiazem.

For prescribers, it is important to note that the concentration of diltiazem in this formulation is 20 mg/ml, allowing for precise dosing tailored to the individual patient's requirements. The liquid form should be measured with an appropriate device such as an oral syringe or a medicine dropper to ensure accuracy. It is also crucial to consider the patient's weight, age, and renal and hepatic function when determining the appropriate dose. Regular monitoring of blood pressure and heart rate is recommended to assess the efficacy and safety of the treatment.

Patients should be instructed on how to properly measure and take their medication, and to adhere to their dosing schedule as prescribed by their healthcare provider. They should also be made aware of potential side effects, which may include dizziness, lightheadedness, weakness, and gastrointestinal disturbances. Patients should be advised to report any adverse effects or concerns to their healthcare provider promptly.

As compounding pharmacists at Bayview Pharmacy, we are committed to providing high-quality, customized medications to meet the unique needs of our patients. If you have any questions about the Diltiazem HCl 20 mg/ml Oral Liquid formulation or its administration, please do not hesitate to reach out to us for further information and guidance.

Drug Interactions

A small arrow pointing down

Diltiazem HCl is a calcium channel blocker that is used to treat hypertension (high blood pressure), angina (chest pain), and certain heart rhythm disorders. When formulated as a 20 mg/ml oral liquid, it provides an alternative for patients who have difficulty swallowing tablets or capsules. However, diltiazem is known to interact with a variety of medications and substances, which can lead to either increased side effects or reduced efficacy of treatment.

One of the most significant interactions occurs with drugs that are metabolized by the liver enzyme CYP3A4, as diltiazem is an inhibitor of this enzyme. This can lead to increased levels of these drugs in the body, potentially causing toxicity. Examples include certain statins (such as simvastatin and atorvastatin), benzodiazepines, and some antiviral medications. Patients should be closely monitored and dosage adjustments may be necessary when diltiazem is co-administered with these drugs.

Concomitant use of diltiazem with beta-blockers or digoxin can lead to an additive effect on the heart, potentially resulting in bradycardia (slow heart rate), conduction disturbances, or heart failure. Patients should be monitored for signs of excessive cardiac depression when these medications are used together. Additionally, combining diltiazem with other antihypertensive agents can enhance the blood pressure-lowering effects, which may require dose adjustments to avoid hypotension (low blood pressure).

Grapefruit juice can increase the plasma concentrations of diltiazem, as it inhibits CYP3A4. Patients should be advised to avoid grapefruit and grapefruit juice while taking diltiazem oral liquid to prevent unintended increases in drug levels. Alcohol consumption should also be approached with caution, as it may enhance the blood pressure-lowering effects of diltiazem and increase the risk of side effects such as dizziness or fainting.

Patients taking diltiazem should also be cautious about using over-the-counter medications and herbal supplements. For example, St. John's Wort can decrease the effectiveness of diltiazem by inducing CYP3A4, while supplements like magnesium or coenzyme Q10 may have additive effects on blood pressure and heart rate.

It is crucial for patients and prescribers to be aware of these interactions when considering the use of diltiazem HCl 20 mg/ml oral liquid. A thorough medication review should be conducted to identify any potential interactions before starting treatment. Dose adjustments or alternative therapies may be necessary to ensure safe and appropriate use of this medication. If you have any questions or concerns regarding drug interactions with diltiazem, please reach out to us at Bayview Pharmacy for further assistance.

How Does it Work

A small arrow pointing down

Diltiazem HCl, the active ingredient in this oral liquid formulation, is a calcium channel blocker that works by inhibiting the influx of calcium ions into cardiac and vascular smooth muscle cells. This action results in the dilation of coronary and systemic arteries, leading to a decrease in blood pressure and a reduction in the workload of the heart. By relaxing the vascular smooth muscle, diltiazem reduces the force of contraction of the heart and decreases the rate at which the heart beats.

The 20 mg/ml concentration of Diltiazem HCl in this oral liquid formulation allows for precise dosing tailored to the individual needs of the patient. The liquid form is particularly beneficial for patients who have difficulty swallowing pills, such as the elderly or children, or for those with conditions that affect the esophagus or swallowing reflex. The liquid formulation ensures that the medication can be administered easily and absorbed quickly into the bloodstream for a rapid onset of action.

When taken as directed, this oral liquid formulation of Diltiazem HCl can help to restore normal heart rhythms, relieve chest pain, and lower high blood pressure, thereby reducing the risk of stroke, heart attack, and other heart-related complications. It is important for patients and prescribers to understand that consistent, regular dosing is crucial for the management of cardiovascular conditions. As with any medication, it is essential to follow the dosing instructions provided by the healthcare provider to achieve the best therapeutic outcomes.

For patients and prescribers interested in using this Diltiazem HCl oral liquid formulation, it is important to consider the patient's complete medical history, including any other medications being taken, to avoid potential drug interactions. Monitoring for side effects, such as dizziness, headache, or swelling of the extremities, is also important for safe and appropriate use of the medication. If you have any questions or require further information about this formulation, please do not hesitate to reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide guidance and support to ensure optimal care for our patients.

Enter the formula as a compound

Compounded preparations have no NDC, so this formula will not appear in your EHR's drug search. Use your system's compound, non-formulary, or free-text prescription entry and name the preparation exactly as written in step 3. If your EHR forces you to pick a listed drug, pick the closest entry for the active ingredient and put the full formula in the prescription body (the Sig or directions field), not in Notes to Pharmacy.

Compounded preparations have no NDC and will not appear in your drug search. For EPCS to validate, select a drug entry your EHR recognizes as controlled, usually the bulk powder entry for the active ingredient (for example Ketamine (bulk) powder, not a branded product), then put the full formula from step 3 in the prescription body. A free-text entry that does not validate as controlled will be rejected by your EPCS module.
