Certain compounds and extracts are also not highly soluble in DMSO. In such The anticonvulsant diazepam, for example, which is relatively.

For most large-scale compound screens, therefore, small molecules are delivered to zebrafish embryos and larvae by aqueous exposure. The concentration of compounds in these stock solutions can range up to 10 mM or 10 mg/ml for most small molecules, depending on the dilution factor and the final concentration to be tested. As many compounds exhibit limited solubility in aqueous solution, the use of organic solvents is required to create stock solutions that can then be diluted in the embryo medium.

Sedation due to the influence on the reticular formation of the brain stem and the nonspecific thalamic nuclei and manifested a decrease in symptoms of neurotic origin.

Symptoms: severe drowsiness, prolonged confusion, decreased reflexes, prolonged dysarthria, nystagmus, tremor, bradycardia, dyspnea or shortness of breath, decreased blood pressure, coma.

Packaging: Storage:. If you cancel Phenazepam reduce the dose gradually. In order to avoid the development of drug dependence at course treatment duration Phenazepam application is 2 weeks (in some cases the duration of treatment can be increased up to 2 months).

When sleep disorders - 0.5 mg for 20-30 minutes before bedtime.

In the treatment of epilepsy - 2.10 mg / day.

In neurological practice for diseases with muscle hypertonicity appoint 2-3 mg 1-2 times a day.

f plot, has been applied to the solubilities of benzocaine, diazepam, and phenytoin in mixtures of polar, aprotic cosolvents, and water. The log-linear solubility equation, log (S m /S w ) = fσ, whereS m and S w are the solubilities of drug in the solvent mixture and water, respectively,f is the volume fraction of cosolvent, and σ is the slope of the log (S m /S w ) vs. Solubilities are generally higher in both groups of cosolvent -water mixtures compared to amphiprotic cosolvent-water mixtures.

In conclusion, the time-dependent inhibition of CYP3A4 by diazepam was attenuated by DMSO, while acetonitrile and methanol had no effect. Dixon plots revealed that the metabolism of diazepam in rCYP3A4 were inhibited by DMSO in a competitive or mixed-type manner with K(i) (inhibition constant) values of 6 and 24 mM for nordiazepam and temazepam, respectively. In contrast, the inactivation by diazepam dissolved in 1% DMSO significantly decreased and the kinetic parameter could not be calculated. The formation rate of nordiazepam and temazepam metabolized from diazepam dissolved in DMSO were approximay half of those using substrate dissolved in acetonitrile and methanol in both HLM and rCYP3A4. The metabolite formation profile under the conditions tested suggested that DMSO competitively inhibit the formation of the reactive metabolites of diazepam by CYP3A4. The effect of organic solvents should be taken into consideration when evaluating the in vitro time-dependent inhibition of new chemical entities. The inactivation kinetics of CYP3A4 by diazepam dissolved in acetonitrile and methanol were almost equal with k(inact)/K(I) values, 0.095 and 0.15 min(-1) mM(-1) for HLM and 1.1 and 1.4 min(-1) mM(-1) for rCYP3A4, respectively. The effects of organic solvents, acetonitrile, dimethyl sulfoxide (DMSO), and methanol, which are used to dissolve lipophilic test compounds and cytochrome P450 (P450) substrates, and carried into pre-incubation at 1% (v/v), on time-dependent inhibition of CYP3A4 by diazepam, were evaluated using human liver microsomes (HLM) and recombinant human P450 expressed microsomes (rCYPs).
