Introduction

In the pharmaceutical world, paracetamol is one of the most commonly used drugs to treat pain and reduce fever. However, paracetamol has a low level of solubility in water, which often requires the use of co-solvents such as alcohol or propylene glycol to prepare a solution. The use of alcohol is not safe for children, while propylene glycol has been known to cause acute kidney failure in children. Therefore, suspension preparation is a solution to this problem, although the suspension also has weaknesses, namely the possibility of clumping. In this context, the authors are interested in developing paracetamol nanosuspension formulations that do not contain co-solvents and mixed solvents, and are able to prevent clumping.

Research Purposes

This study aims to make paracetamol nanosuspension using the top down method, characterize, and test the analgesic and antipyretic effects in vivo. In this study, the effects of nanosuspension will be compared with paracetamol suspension and solutions. The development of paracetamol nanosuspension is expected to provide a safer and more efficient formulation for patients, especially children. The use of nanosuspension technology can improve the solubility and bioavailability of paracetamol, making it more effective in managing pain and fever.

Methodology

This research was conducted through several stages. First, the identification of raw materials is done to determine the quality of the material to be used. Then, paracetamol nanosuspension is produced using the top down method. The top down method involves the use of high-energy milling to break down the paracetamol particles into smaller sizes. After manufacturing, the characterization of nanosuspensions is carried out, including organoleptic examination, measurement of particle size, potential zeta, pH, specific gravity, ratio, and solubility test and stability for three months. After the characterization stage, followed by testing therapeutic activity using white mice. This test includes analgesic tests using the hot plate method with five antipyretic treatment and tests carried out with induction of 2-6-dinitrophenol with six treatment groups.

Characterization of Nanosuspension

The characterization of nanosuspension is an important step in determining the quality and stability of the formulation. The organoleptic examination is used to evaluate the appearance, smell, and taste of the nanosuspension. The measurement of particle size is used to determine the size of the paracetamol particles in the nanosuspension. The potential zeta is used to determine the charge of the paracetamol particles in the nanosuspension. The pH is used to determine the acidity or basicity of the nanosuspension. The specific gravity is used to determine the density of the nanosuspension. The ratio is used to determine the concentration of paracetamol in the nanosuspension. The solubility test is used to determine the solubility of paracetamol in the nanosuspension. The stability test is used to determine the stability of the nanosuspension over a period of three months.

Therapeutic Activity Test

The therapeutic activity test is an important step in determining the effectiveness of the nanosuspension formulation. The analgesic test is used to evaluate the pain-relieving effect of the nanosuspension. The antipyretic test is used to evaluate the fever-reducing effect of the nanosuspension. The hot plate method is used to evaluate the analgesic effect of the nanosuspension. The 2-6-dinitrophenol induction method is used to evaluate the antipyretic effect of the nanosuspension.

Research Result

The results showed that paracetamol levels in nanosuspension, suspension, and appropriate solutions were 108.22%, 94.45%, and 103.26%. In analgesic and antipyretic testing, nanosuspensions show a better effect than suspension, although there is no significant difference between nanosuspensi and solutions. The results of this study indicate that the top down method can be used to produce paracetamol nanosuspension with improved solubility and bioavailability.

Conclusion

Based on this research, it can be concluded that paracetamol can be formulated in the form of nanosuspensions using the top down method. Nanosuspensi has an advantage in terms of solubility that is faster compared to suspension. This discovery opens new opportunities in the development of drug formulations, especially to increase the effectiveness of paracetamol in the form of safer and efficient nanosuspension for patients, especially children. By understanding and applying this nanosuspension method, it is expected that the use of paracetamol can be more optimal, having a positive impact in managing pain and fever.

Future Direction

The results of this study indicate that the top down method can be used to produce paracetamol nanosuspension with improved solubility and bioavailability. However, further studies are needed to evaluate the long-term stability and safety of the nanosuspension formulation. Additionally, the use of nanosuspension technology can be applied to other drugs to improve their solubility and bioavailability. The development of nanosuspension technology can provide new opportunities in the field of pharmaceuticals, especially in the development of safer and more efficient drug formulations.
