Opis:
Gels containing lactic acid complexed with chitosan at a stoichiometric ration 1:1 and 2:1 and 5-25% content of polyoxyethylene glycol 200 are able to move from 25 to 30 cm. The addition of 4% hydroxypropylmethylcellulose besides glycerol increases the movability gels containing lactic acid complexed with chitosan in a stoichiometric ration 1:1 from 25 cm to 28 cm and at 2:1 ratio from 27 cm to 30 cm. Higher concentrations of the poloxamer 407: 23 and 25% result in the movability of 24 to 29 cm The addition of 5-25% glycerol decreases the pH of investigated gels from 3.95 to 4.45 (1:1) and from 3.63 to 4.30 (2:1). The addition of 5-25% 1,2-propylene glycol decreases the pH of investigated gels from 4.00 to 4.46 (1:1) and from 3.70 to 4.33 (2:1). The use of hydroxypropylmethylcellulose allowed to obtain physiological range. The addition of hydroxypropylmethylcellulose reduces the pH and maintains high adhesion.

Opis:
Gels containing lactic acid complexed with chitosan at a stechiometric ratio 1:1 and 2:1 and 5-25% content of PEG-200 reveal pH from 3.42 to 4.95. The addition of 20 – 25% poloxamer 407 increases the pH from 4.55 to 5.30 for 1:1 gels and from 4.00 to 4.85 for 2:1 gels. The addition of 1.0% dextrane decreases the pH of investigated gels from 4.40 to 4.90 (1:1) and from 4.00 to 4.48 (2:1). The addition of poloxamer 407 at concentrations of 20 to 25% increases the dynamic viscosity from 506.14 to 641.20 for 1:1 and from 540.35 to 692.55 for 2:1 ratios. The addition of 1.0% dextrane increases the dynamic viscosity from 665.23 to 750.28 for 1:1 and from 645.50 to 740.16 for 2:1 ratios. The addition of dextrane and glycerol or 1,2-propylene glycol reduces the pH and maintains high adhesion. The use of dextrane and hydrophilizing substances allowed to obtain physiological range pH.

Opis:
Gels containing lactic acid complexed with chitosan at a stoichiometric ratio 1:1 and 2:1 and 5 - 25% content of polyoxyethylene glycol 200 reveal pH from 2.5 to 4.6. The addition of 20 – 25% poloxamer 407 increases the pH to 4.55 to 5.30 for 1:1 gels and 4.00 to 4.85 for 2:1 gels. The addition of 0.5% polyvinyl alcohol decreases the pH of the investigated gels to 4.00 to 4.55 for 1:1 gels and 3.85 to 4.40 for 2:1 gels. The addition of 1.0% dextrane decreases the pH of investigated gels to 4.40 to 4.90 (1:1) and 4.00 to 4.48 (2:1). Rheological investigations revealed an increase in the dynamic viscosity of preparations containing poloxamer 407 with the addition of polyvinyl alcohol or dextrane in comparison to the reference gels. Results obtained in the experimental studies proved that it is possible to produce a preparation with optimal pharmaceutical and application properties.

Opis:
Gels containing lactic acid complexed with chitosan at a stoichiometric ration 1:1 and 2:1 and 5-25% content of polyoxyethylene glycol 200 are able to move from 25 to 30 cm. Measurements performed in a biopharmaceutical model revealed that the addition of 20% poloxamer 407 to gels containing lactic acid complexed with chitosan in a stoichiometric ration 1:1 decreases their movability from 20 to 25 cm and at 2:1 ratio, from 22 to 28 cm. Higher concentrations of the poloxamer 407: 23 and 25% result in the movability of 20 to 24 cm. The addition of 5% PVP K-30 besides 1,2-propylene glycol increases the movability gels containing lactic acid complexed with chitosan in a stoichiometric ration 1:1 from 24 cm to 28 cm and at 2:1 ratio from 26 cm to 30 cm. Higher concentrations of the poloxamer 407: 23 and 25% result in the movability of 24 to 27 cm

The addition of glycerol increases the movability gels containing lactic acid complexed with chitosan in a stoichiometric ration 1:1 from 23 cm to 26 cm and at 2:1 ratio from 25 cm to 29 cm. Gels with addition 20-25% poloxamer 407 containing lactic acid complexed with chitosan and 5-25% content of glycerol reveal pH from 4.25 to 4.98 for 1:1 and from 3.60 to 4.45 for 2:1. The investigations showed that the addition of a thermosensitive polymer increases the adhesive properties of the investigated gels, but at the same time it increases their pH. The addition of glycerol or 1,2-propylene glycol reduces the pH and maintains high adhesion. The use of hydrofilizing substances allowed to obtain physiological range pH gynaecological gels.
