| name | Calcium Channel Blockers |
| classification | Antihypertensives, Antianginals, Antiarrhythmics |
| pharmacokinetics | | 1 | | description | Absorption varies significantly depending on the specific calcium channel blocker. Some are well absorbed orally, while others are better absorbed intravenously. Distribution depends on the drug's lipophilicity and tissue binding. Metabolism is variable and often hepatic. Excretion is mostly renal. |
| | 2 | | specific details | Individual calcium channel blockers exhibit variations in their pharmacokinetic profiles, impacting their onset and duration of action. |
|
|
| suggested dosage | Dosage varies significantly based on the specific calcium channel blocker and the patient's condition. Consult a physician for appropriate dosage. |
| indications | | 1 | | condition | Hypertension | | description | Calcium channel blockers are effective in lowering blood pressure, especially in patients with specific risk factors or contraindications for other antihypertensives. |
| | 2 | | condition | Angina Pectoris | | description | They improve coronary blood flow, reducing the frequency and severity of angina attacks. |
| | 3 | | condition | Cardiac Arrhythmias | | description | Some calcium channel blockers are used to control specific types of abnormal heartbeats. |
| | 4 | | condition | Raynaud's Phenomenon | | description | These medications can improve blood flow to the extremities in patients with this condition. |
|
|
| safety in pregnancy | | description | While generally considered relatively safe during pregnancy in some specific circumstances, caution is vital, especially in the third trimester. Individual risks vary based on the specific calcium channel blocker. Consult with a physician. | | specific notes | Certain calcium channel blockers may be associated with adverse outcomes in the fetus or newborn. It is crucial to carefully evaluate the potential benefits and risks with the treating physician. |
|
| safety in breastfeeding | | description | Some calcium channel blockers may pass into breast milk; however, their effects on infants are generally low, particularly in low doses. This warrants individual evaluation by the physician considering the infant's health. Consult a physician for advice. | | specific notes | Individual calcium channel blockers have varying degrees of excretion into breast milk. Consulting with a medical professional is critical. |
|
| side effects | | 1 | Headache | | 2 | Dizziness | | 3 | Peripheral edema (swelling) | | 4 | Flushing | | 5 | Constipation | | 6 | Bradycardia (slow heart rate) | | 7 | Hypotension (low blood pressure) | | 8 | Edema (swelling) |
|
| alternatives | |
| contraindications | | 1 | Severe hypotension (low blood pressure) | | 2 | Sick sinus syndrome | | 3 | Second- or third-degree atrioventricular block (unless a pacemaker is in place) | | 4 | Severe hepatic impairment | | 5 | Hypersensitivity to calcium channel blockers |
|
| interactions | | 1 | | drug | Beta-blockers | | interaction | May potentiate bradycardia and hypotension |
| | 2 | | drug | Digoxin | | interaction | May increase digoxin blood levels, increasing the risk of toxicity |
| | 3 | | drug | CYP3A4 inhibitors | | interaction | May increase calcium channel blocker concentrations. |
|
|
| warnings and precautions | Patients with pre-existing heart conditions, liver disease, or kidney problems should exercise caution when using calcium channel blockers. Regular monitoring of blood pressure and heart rate is necessary. |
| additional informations | Different types of calcium channel blockers have different effects on the body. Consulting a medical professional is crucial to determine the most suitable medication and dosage for the individual patient. |
