GABA Pharmacology



GABA acts as a major inhibitory neurotransmitter in the human brain by taking control of over excitation state of neurons and induces a sense of calmness and relaxation. Gamma amino butyric acid is mainly found in the mammalian nervous system, and effectively operates with the help of membrane receptors for glutamate and extracellular GABA. An inhibition caused by this neurotransmitter is highly important for the proper brain functioning depression remedies. However, too little or too much excitation in brain nerve cells might cause depression, coma, low blood pressure, anxiety, convulsions, insomnia and restlessness.

GABA Pharmacology

GABA mainly operates with Bicuculline sensitive CI-channels, through the GABAA receptors along with the bicuculline insensitive action channels through GABAB receptors foods for depression. The most important part of GABA pharmacology is GABAA as it is mainly involved in the synaptic transmission. GABAA is mainly targeted by all the medicine companies in order to treat depression, stress and anxiety.

Lower extracellular concentration of amino acids is manly maintained with the help of highly specific transporters. Glutamate and GABA that is released synoptically from the synoptic environment is effectively removed from these transporters. As a result, these transporters immediately terminate synaptic actions. CNS active agents like steroids, ethanol, neurotoxins, benzodiazepines and barbiturates play a major role in performing actively over the glutamate and GABA transmitter systems.

Mainly three families of GABA are cloned throughout the mechanism i.e. GABAA, GABAB and GABAC. These receptors are made up of five protein subunits that are considered an effective transmitter gated ion channel receptors.

Many researchers have studied the GABA pharmacology in recent years in an effort of finding more facts about this amino acid. If you look at the medical history then you would find that massive progress has been made over the last thirty years. Scientists have been trying to understand the mechanism of GABA. The pharmacology of GABA mainly composed of memory enhancers, non-sedative, hypnotics, anxiolytics and powerful analgesics.

Herbal Supplements for Depression

An individual suffering from depression or stress tends to have lower level of GABA in the nervous system and as a result, excitation state occurs in nerve cells of the human brain. Under such circumstances, people try taking help from several herbal supplements or other natural remedies to get rid of the GABA depression.

Herbal supplements for GABA depression mainly composed of St. John’s Wort, 5- HTP, Omega 3 fatty acids, Valerian, Lavendar, Peppermint, Gingko Biloba, Rhodiola Rosea and many more. These herbal supplements help an individual to get rid of depression by inducing a state of relaxation but could also few side effects. Thus, it is always recommended to use these herbal supplements for depression after consulting your physician. You need to make sure that these supplements will not interfere with other medications you might be taking. Moreover, there is not any specific dosage provided for these supplements. Individuals are required to take supplements based on their medical conditions thus varies significantly from an individual to individual.
