| name | Bisphosphonates (Generic) |
| classification | Antiresorptive Agents, Bone-Modifying Drugs |
| pharmacokinetics | Bisphosphonates are poorly absorbed from the gastrointestinal tract. They bind strongly to bone mineral and are slowly released. The duration of action is related to the half-life in bone, which can be years. Renal excretion is the primary elimination pathway. Specific pharmacokinetic properties vary between individual bisphosphonates. |
| suggested dosage | Dosage varies significantly depending on the specific bisphosphonate and the condition being treated. It's crucial to follow the prescription instructions provided by a healthcare professional. A 25-year-old male patient with a weight of 70kg should not attempt to self-administer bisphosphonates. |
| indications | | 1 | Osteoporosis (prevention and treatment) | | 2 | Paget's disease of bone | | 3 | Osteogenesis imperfecta | | 4 | Bone metastases | | 5 | Other bone conditions |
|
| safety in pregnancy | Bisphosphonates are generally not recommended during pregnancy due to potential risks to the developing fetus. Specific advice should be sought from an obstetrician and treating physician. |
| safety in breastfeeding | It is not known if bisphosphonates are excreted in breast milk. Due to potential risks, breastfeeding is usually discouraged while taking bisphosphonates. |
| side effects | | 1 | Gastrointestinal upset (e.g., heartburn, abdominal pain, nausea, vomiting) | | 2 | Esophagitis (irritation of the esophagus) | | 3 | Jaw osteonecrosis (rare but serious) | | 4 | Bone, muscle, or joint pain | | 5 | Headache | | 6 | Fatigue | | 7 | Dyspepsia | | 8 | Musculoskeletal pain | | 9 | Mild skin reactions |

| alternatives | |
| contraindications | | 1 | Hypersensitivity to bisphosphonates | | 2 | Significant esophageal abnormalities (e.g., strictures, achalasia) | | 3 | Inability to remain upright for at least 30-60 minutes after taking the medication | | 4 | Severe renal impairment |
|
| interactions | Bisphosphonates can interact with some medications. Consult with the prescribing physician about any other medications the patient is taking. For example, antacids may reduce absorption. |
| warnings and precautions | | 1 | The risk of esophageal irritation is greater when bisphosphonates are taken without food or with a small amount of food. Patients should consult the prescribing physician for recommendations. | | 2 | Patients should take the medications as directed. Missed doses should be reported immediately to a physician. | | 3 | Long-term use may cause certain side effects. Patients should discuss with the physician the benefits and risks for long term use. | | 4 | Monitor renal function during treatment, especially with prolonged therapy. |
|
| additional information | Bisphosphonate therapy should be individualized. Patients should discuss potential benefits and risks with their physician to determine the most suitable treatment strategy for their individual needs and medical history. Consult a physician or pharmacist with specific questions. |
