Clinical monograph: hydroxyapatite
BNF-referencedHydroxyapatite is a naturally occurring mineral form of calcium apatite, with the molecular formula Ca5(PO4)3(OH). It is a major component of bone and teeth, providing structural integrity. Hydroxyapatite is used in various medical applications, particularly in orthopedics and dentistry, for bone grafting and dental implants due to its biocompatibility and osteoconductive properties.
Indications
- Bone defects
- Osteoporosis
- Dental implants
- Bone grafting
- Maxillofacial surgery
Dosage
Children: Refer to specific guidelines for paediatric applications, as dosage can vary significantly based on age and condition.
Adults: Dosage varies based on specific formulation and clinical application; refer to product-specific guidelines.
Mechanism of action
Hydroxyapatite facilitates bone repair and regeneration by providing a scaffold for new bone formation. It promotes osteoblast activity and serves as a reservoir for calcium and phosphate ions, essential for mineralization processes in bone tissue.
Pharmacodynamics
Hydroxyapatite exhibits osteoconductive properties, allowing for the formation of new bone tissue around it. It enhances the mineralization process, which is crucial for the strength and stability of the newly formed bone. Its chemical structure closely resembles that of natural bone, promoting better integration and healing.
Pharmacokinetics
Hydroxyapatite is not absorbed in the traditional sense as it is used primarily as a biomaterial. It remains at the site of implantation and gradually gets integrated into the host bone. Its degradation and resorption rates vary depending on the specific formulation and application but are generally slow, allowing for sustained support during the healing process.
Pregnancy
There are no adequate and well-controlled studies in pregnant women. Hydroxyapatite should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Breast-feeding
It is not known whether hydroxyapatite is excreted in human milk. Caution should be exercised when hydroxyapatite is administered to a nursing woman.
Storage
Store in a cool, dry place, away from direct sunlight. Keep out of reach of children.
