In the United States, approximately 1 in every 25 adults was prescribed a benzodiazepine in 2021, a class of drugs that works by enhancing GABA's effects [1.4.5]. So, is there a drug that increases GABA? The answer is yes, and there are several types.

In 2021, approximately 1 in 25 adults in the United States were prescribed a benzodiazepine. These widely used medications work by altering brain chemistry, and understanding what neurotransmitter do benzodiazepines increase is crucial for grasping their sedative, anxiolytic, and anticonvulsant effects.

In the United States, approximately 30.6 million adults report using benzodiazepines [1.6.2]. A common question is, do benzos deplete GABA? The answer is more complex, involving receptor sensitivity rather than depletion.

By 2025, the estimated prevalence of Parkinson's disease in the UK is expected to increase by 23.2% due to an aging population [1.6.3]. This condition is caused by a lack of dopamine, and a primary question for patients is: **does levodopa restore dopamine levels?** [1.2.1].

Over 14.5 million U.S. adults experienced at least one major depressive episode in 2021, and for many, Lexapro is a prescribed treatment. A primary question often asked is: "Does Lexapro increase serotonin?" The answer is a definitive yes, as this mechanism is central to its therapeutic effect.

In 1995, Riluzole (marketed as Rilutek) became the first FDA-approved medication for the treatment of Amyotrophic Lateral Sclerosis (ALS). The medication works primarily by inhibiting the activity of glutamate, a major excitatory neurotransmitter in the central nervous system. By interfering with glutamatergic signaling, the drug helps to reduce the neurotoxicity believed to contribute to the progressive nerve cell damage seen in ALS.

In 2022, an estimated 48.7 million people aged 12 or older had a substance use disorder [1.4.3]. This is often driven by the brain's reward system, raising the question: what is the pleasure drug, and how do substances manipulate it?

Studies show that in individuals with insomnia, Gamma-Aminobutyric Acid (GABA) levels can be almost 30% lower than in those without sleep disturbances [1.5.2]. This raises the question: **How long does it take for GABA to go back to normal?**

As a well-documented side effect, tremors or shaking can affect patients taking bupropion (Wellbutrin), particularly at higher doses of 300-400 mg/day. While often bothersome, there are several medical and lifestyle adjustments that can help manage these involuntary movements and address how to stop wellbutrin tremors.

Tamsulosin is a widely prescribed alpha-1 adrenergic antagonist for benign prostatic hyperplasia (BPH) [1.4.2]. A critical question for users is: **does tamsulosin affect dopamine**, and what are the potential neurological implications of its off-target effects in the central nervous system? [1.2.1, 1.2.2]
