| Summary: | The article goes to describe clinical and pharmacological approaches to choosing a drug with an optimal efficacy/safety profile, providing the necessary analgesic effect in tension-type headache. TRPV1 brain receptors are considered the main action point of the mediator.
Aim. The purpose of this study is a comparative analysis of the pharmacodynamic and pharmacokinetic parameters of ibuprofen and paracetamol as a part of fixed dose combination and as monotherapy in tension type headaches.
Materials and methods. Comparative dissolution kinetics test; Comparative analysis of pharmacokinetic parameters using the PubMed/MEDLINE database.
Results. The median Tmax of ibuprofen as a part of a fixed-dose combination and as a monotherapy is 75 minutes. The median Tmax of paracetamol is 30 min when taken in a fixed dose combination and 40 min as a monotherapy. In patients who received the fixed dose combination, the concentration of ibuprofen in the blood plasma after 10 minutes 6.64 g/ml-1; after 20 minutes 16.81 g/ml-1, while when taken in the same dose in as a monotherapy, respectively, 0.58 and 9.00 g/ml-1. The mean plasma concentrations of paracetamol after 10 and 20 minutes in patients receiving the fixed combination were 5.43 and 14.54 g/ml-1, respectively, compared with 0.33 and 9.19 g/ml-1 for paracetamol as monotherapy. dissolution kinetics test of the Paracytolgin: after 5 minutes, 20% of paracetamol passed into the solution in a system with a pH of 1.2; in a system with a pH of 4.5 36.4%; in a system with a pH of 6.8 33.5%; after 10 minutes, respectively 68.5, 98.0 and 89.6%. After 15 minutes, almost complete dissolution was noted in all systems: 98.5, 98.8 and 100.5%, respectively.
Discussion. The combination of ibuprofen and paracetamol makes it possible to enhance the analgesic effect as a result of additive action by the help of central mechanisms. The fixed dose combination of ibuprofen and paracetamol significantly increases the rate of absorption of paracetamol, which has potential therapeutic benefits in terms of a faster analgesias onset.
Conclusion. The fixed dose combination of ibuprofen and paracetamol provides faster and long-term anaesthesia with a comparatively lower dosage of each analgesic. |
