Novel drug-drug eutectics of etodolac with paracetamol (EP) and etodolac with propranolol hydrochloride (EPHC) were synthesized, showing enhanced dissolution and material properties. These combinations offer improved therapeutic effects for osteoarthritis and cancer chemotherapy.
Area of Science:
- Pharmaceutical Sciences
- Supramolecular Chemistry
- Drug Delivery Systems
Background:
- Combinational therapy offers advantages such as enhanced efficacy and patient compliance.
- Drug-drug multicomponent adducts enable supramolecular drug combinations.
- Etodolac, paracetamol, and propranolol hydrochloride are common therapeutic agents.
Purpose of the Study:
- To design and synthesize novel drug-drug eutectics of etodolac with paracetamol (EP) and etodolac with propranolol hydrochloride (EPHC).
- To evaluate the dissolution and material properties of these novel eutectic mixtures.
- To assess the therapeutic potential of EP and EPHC in relevant cell culture models.
Main Methods:
- Synthesis of etodolac-paracetamol (EP) and etodolac-propranolol hydrochloride (EPHC) eutectics.
- Dissolution efficiency and hardness testing of eutectic mixtures compared to pure drugs.
- Cell culture studies including Western blotting for inflammatory mediators (TNF-α, COX-2, IL-6) and cytotoxicity assays.
Main Results:
- Successfully synthesized EP and EPHC eutectics with significantly improved dissolution rates (6-9 fold enhancement in % dissolution efficiency at 1 min).
- Eutectic mixtures exhibited enhanced hardness (EP: ~5 fold, EPHC: ~3 fold improvement at 10 MPa).
- EP demonstrated reduced inflammatory mediators; EPHC showed enhanced cytotoxic effects with synergistic and favorable dose reduction indices.
Conclusions:
- EP and EPHC represent promising multi-component systems with fast-dissolving capabilities and improved material properties.
- These eutectic combinations show potential for effective treatment of osteoarthritis (EP) and cancer chemotherapy (EPHC).
- The study highlights the utility of supramolecular adducts for developing advanced combination therapies.
