- CRPS complex regional pain syndrome
- An incapacitance device (IITC Inc. Life Science, Woodland, CA, USA) was used to measure hindpaw weight bearing, a postural effect of pain.
- the rats were manually held in a vertical position over the apparatus with the hindpaws resting on separate metal scale plates and the entire weight of the rat was supported on the hindpaws. The duration of each measurement was 6 seconds and 10 consecutive measurements were taken at 60-second intervals. Eight readings (excluding the highest and lowest ones) were averaged to calculate the bilateral hindpaw weight-bearing values. Weight bearing data were analyzed as the ratio between right (fracture) and left hindpaw weight bearing values ((2R/(R+L)) x100%).
- a laser sensor technique was used to determine the dorsal-ventral thickness of the hindpaw.
- the bilateral hindpaws were tattooed with a 2 to 3 mm spot on the dorsal skin over the midpoint of the third metatarsal.
- each rat was briefly anesthetized with isoflurane and then held vertically so the hindpaw rested on a table top below the laser.
- the paw was gently held flat on the table with a small metal rod applied to the top of the ankle joint.
- a laser with a distance measuring sensor was used to determine the distance to the table top and to the top of the hindpaw at the tattoo site and the difference was used to calculate the dorsal-ventral paw thickness.
- the measurement sensor device used in these experiments (4381 Precicura, Limab, Goteborg, Sweden) has a measurement range of 200 mm with a 0.01 mm resolution.
- the temperature of the hindpaw was measured using a fine wire thermocouple (Omega, Stanford, CT, USA) applied to the paw skin. Six sites were tested per hindpaw. The six measurements for each hindpaw were averaged for the mean temperature.
- the daily dose in the above experiment was 18 mg/m 2 /day. Under current FDA guidelines, the reference body surface area of a human adult is 1 .62 m 2 . Thus, a daily dose of 18 mg/m 2 corresponds to a monthly dose of about 500-560 mg/m 2 or a human dose of about 800-900 mg.
- aqueous solubility of zoledronic acid and disodium zoledronate tetrahydrate was determined.
- One gram of the test compound was measured in to a beaker. Demineralized water (pH 5.5) was then added in small increments to the test compound, and sonification was applied to the mixture. The procedure was continued until complete dissolution was achieved. Full dissolution was determined to have been reached when a clear solution was present with no visible material. The volume of water required to reach full dissolution was used to calculate a solubility value expressed in grams per 100 mL. The procedure was performed for each compound.
- the aqueous solubility of disodium zoledronate tetrahydrate is approximately 50 times that of zoledronic acid.
- Disodium zoledronate tetrahydrate has a solubility of 12.5 g/100 mL compared to only 0.25 g/100 mL for zoledronic acid.
- Tablets were manufactured containing either pure zoledronic acid or the disodium salt of zoledronic acid (disodium zoledronate tetrahydrate). Both types of tablets contained 50 mg of zoledronic acid equivalent per tablet. Identical excipients were used in both types of tablets, with amounts adjusted to account for the difference in molecular weights between the acid and the disodium salt.
- Beagle dogs were orally administered tablets containing 150 mg zoledronic acid equivalent either in the form of disodium zoledronate (Group 1 ) or pure zoledronic acid (Group 2). Each animal was given three 50 mg equivalent tablets (150 mg total), which were administered together. The animal's oral cavity was wetted with water before placing the tablets on the back of the animal's tongue. Animals were fasted before and after dosing. Animals were 6 to 9 months of age and weighed 6 to 10 kg on the day of dosing. There were three dogs per group.
- Serial blood samples were collected from each animal by venipuncture of the jugular vein at various points after dosing for measurement of plasma concentrations of zoledronic acid. Blood samples were collected into chilled tubes containing K 2 EDTA as the anticoagulant. Samples were then centrifuged at approximately 3000 rpm at +4°C for 10 minutes for plasma derivation. Plasma concentrations of zoledronic acid were measured using an LC/MS/MS method.
- Disodium zoledronate produced significantly higher plasma levels of zoledronic acid than pure zoledronic acid, indicating improved oral absorption with the salt form.
- Measured using peak plasma concentrations (C m ax) > the disodium salt resulted in a 1 19% actual and 74% weight-adjusted increase in bioavailability as compared to pure zoledronic acid.
- Measured using area under the plasma concentration curve (AUCo- ⁇ ) bioavailability was 84% and 46% greater with the disodium salt than with pure zoledronic acid, on an actual and weight-adjusted basis respectively.
- the average AUCo- ⁇ for the disodium salt was 4073 ng » hr/ml_ and the average AUCo- ⁇ for the diacid was 2217 ng » hr/ml_.
- the AUCo- ⁇ was found to be dose proportional.
- about 3 mg to about 4 mg of the disodium salt would be expected to result in an AUCo- ⁇ of about 100 ng » hr/ml_, and about 7 mg to about 8 mg of the disodium salt would be expected to result in an AUCo- ⁇ of about 200 ng » hr/ml_.
- Tablets were prepared by blending zoledronic acid, either in the form of the free acid or the disodium salt, with identical excipients. For dosage forms with a greater amount of active, the amount of the excipients was reduced proportionally to keep the weight of the tablet at about 100 mg. After blending, the ingredients were compressed at varying pressures, followed by a film coating. The resulting tablets were then tested for hardness using a Dr. Schleuniger Pharmatron 8M Tablet Hardness Tester. The results are shown in Table 2 and FIG. 9. Table 2
