Complejo Hospitalario Universitario de Pn, Pontevedra. The objective of this study is what are causative agents of disease determine the optimum pH range for the oral liquid formulations more frequently prepared at the Pharmacy Unit, in order to standardize and incorporate said value into the standard protocols of action as a quality control criterion.

The study was conducted in three stages. The first stage consisted in a retrospective study of the records of preparation of those oral liquid formulations prepared at least 5 times since January, to December,in our Pharmacy Unit; the main value and standard deviation of the pH values recorded for each formulation were calculated. In a second stage, there was a bibliographic search in order to understand the pH for the maximum stability of the molecule, and to confirm if this characteristic was recorded as a requirement for quality control in the procedures described in the formulation guidelines.

In the third stage, it was confirmed levl the pH values determined coincided with the maximum stability pH described in literature, and acceptance ranges were established. The maximum si pH value was known for 19 what is the ph level of base The pH range for the same bsse work procedure ranged between 0. An optimal pH range has been determined for the 31 oral liquid formulations more widely prescribed in our hospital.

This characteristic should be part of the galenic validation for these preparations, ie well as of its routine quality control, in order to ensure their quality and efficacy. The pH of an aqueous solution is a critical factor to be considered for all those medications prepared in aqueous liquid forms. Vase potential effect of pH on solubility will be a decisive factor for the baae of the medications to be administered.

Moreover, the biological tolerability of the formulation can be compromised, as well as the activity of the active principle AP 1. Aqueous reactions are generally catalyzed by pH. There have been studies measuring the degradation rates at different pH values, keeping constant the temperature, ionic strength, and bae of the solvent.

The conclusion of these what is linear regression simple definition was that, if pH is not within a maximum stability range, the non-ionized form levle the drug will prevail, leading to the creation of insoluble precipitates 2. Each AP has a pH range for its maximum stability, and it can lose activity outside this range, due to physical and chemical transformations.

The combination with diluents, excipients, and other medications with a different pH, can whxt undesired effects and compromise the stability of the formulation. It has been confirmed that, for example, folic acid and furosemide will precipitate at a pH below 8 and 7, respectively; omeprazole is degraded at pH values below 7. Therefore, pH determination is important for the preparation of oral liquid formulations OLFsbecause it affects the solubility, activity, absorption, biological tolerability and stability of the AP 45.

Given the lack of compatibility data between OLF components, we hereby state that knowing the pH values for maximum stability of the ldvel to be administered is a predictive factor that can prevent serious stability problems, and that its determination will ensure the quality and efficacy of the formulations prepared. The objective of this study is to iss the optimal pH range for the OLFs more frequently prepared at the Hospital Pharmacy Unit HPUin order to standardize and incorporate said value into the standard work procedures SWPs as a quality control criterion.

Mean why does my calls go to another phone and standard deviation were calculated for each what is the ph level of base, as well as the range, obtained through the difference between the maximum and minimum values recorded. In order to determine the maximum stability pH of the AP, the following bibliographic sources were reviewed: the product specifications of the molecules by our main provider www.

The most relevant pediatric formulation guidelines previously mentioned were also consulted 6 8 9 - Finally, the pH values recorded were compared with the maximum stability values stated wuat the bibliography, and an acceptance range was determined for each of the OLFs evaluated. In total, 31 OLFs were reviewed according to the criteria of the first stage of the study: 14 basr and 17 suspensions Table 1.

For all OLFs prepared during the period of the study, and which met the inclusion criteria, the following data were collected: pH mean value, standard deviation, and pH ranges for the same SWP Table 2. Example 32 sets class 11 latter value ranged between 0. Table 1. Table 2. After consulting the different bibliographical sources in order to find the maximum stability pH of the AP, only the value of the 19 Regarding the formulation guidelines consulted, a pH value as quality control was determined for 3 9.

Table 3. Maximum stability pH values for the active principle and pH values of the oral liquid formulations described in the bibliography reviewed. The pH is one of the factors with higher impact on iw stability of hwat formulation in aqueous solution. Knowing the maximum stability pH for an AP of OFLs is essential to guarantee the quality of the preparation; it must remain stable during all the validity and preservation period established 1.

In most of meaning of consequence in tamil formulation guidelines reviewed, pH is not included either as a control to be conducted or an acceptance range; a pH range for each monograph is only described in USP NF Given that there are many medications, such as furosemide, propranolol, omeprazole and captopril, with an already known and well defined pH for maximum stability, and the formulation is not stable unless within it, we consider that this is a value that must wuat known and evaluated, even for individualized formulations fhe prepared in lots 5.

The SWP established should include this criterion. For those OLFs with unknown maximum stability pH range, or insoluble AP, pH determination is still a quality indicator, because it must stay stable and reproducible for the same SWP, as has been demonstrated in the study. This study has been useful in order to include this criterion in the protocol, and its evaluation as quality control. Knowing the maximum stability pH in the preparation of an OLF, and determining an acceptance range as quality control, are indispensable requirements for an adequate galenic validation, and to guarantee treatment efficacy.
