General description

Lamotrigine is an anticonvulsant drug, which is widely used in the treatment of epilepsy and bipolar disorders. It is also used in combination with other antiepileptics to treat refractory partial seizures, generalized tonic-clonic seizures and generalized toxic-chronic seizures.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Application

Labetalol Hydrochloride may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using spectrophotometric technique.
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Biochem/physiol Actions

Anticonvulsant.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Typical therapies try to reverse pathogenic mechanisms. Here, we describe treatment effects achieved by enhancing depression-causing mechanisms in ventral tegmental area (VTA) dopamine (DA) neurons. In a social defeat stress model of depression, depressed (susceptible) mice display hyperactivity of VTA

The mood stabilizers lithium, valproate and lamotrigine are traditionally used to treat bipolar disorder. However, accumulating evidence suggests that these drugs have broad neuroprotective properties and may therefore be promising therapeutic agents for the treatment of neurodegenerative diseases, including stroke.
