Understanding the mechanisms of the pharmacodynamics and pharmacokinetic anxiolytic drugs used to treat GAD is essential. The onset, duration, and possible drug interactions of anxiolytic medicines are determined by their pharmacokinetic properties (Garakani et al., 2020). For instance, certain benzodiazepines, which are anxiolytics, are quickly absorbed and offer prompt relief from anxiety because of their early onset of action. Their quick metabolism and elimination, nevertheless, can cause problems with tolerance and reliance (Garakani et al., 2020). The levels of serotonin and norepinephrine in the brain are increased by selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), which have a delayed onset of action but provide a more long-lasting therapeutic impact. Because of their lesser potential for dependency, these medicines are favored for the long-term therapy of GAD (Garakani et al., 2020).
On the other hand, pharmacodynamics focuses on comprehending how neurotransmitter systems are impacted by anxiolytic drugs. Gamma-aminobutyric acid (GABA), a neurotransmitter that lowers neuronal excitability and promotes relaxation, is made more effective in inhibiting action by benzodiazepines (Nasir et al., 2020). Contrarily, SSRIs and SNRIs function by preventing serotonin and norepinephrine from being reabsorbed, increasing the amount of these neurotransmitters in synaptic clefts, and eventually regulating mood and anxiety (Nasir et al., 2020). While taking into account elements like the onset, duration of action, side effects, and potential interactions, it is essential to understand the pharmacokinetic and pharmacodynamic profiles of these drugs (Nasir et al., 2020).
The goal of psychotherapy, including Cognitive-Behavioral Therapy (CBT), is to alter the thinking and behavior patterns that contribute to anxiety. It helps patients create coping mechanisms and anxiety-management techniques (Curtiss et al., 2021). Contrarily, medicine, such as Benzodiazepines and Selective Serotonin Reuptake Inhibitors (SSRIs), primarily tries to treat the signs and symptoms of anxiety (Melaragno, 2021).
While psychotherapy may take longer to produce observable results, its advantages frequently last after the end of care because patients gain the ability to control their anxiety on their own (Curtiss et al., 2021). Contrarily, medication provides more rapid relief and is frequently advised for people with severe or incapacitating symptoms. Although benzodiazepines entail a danger of dependency, medicines can also cause negative effects (Melaragno, 2021).
While both CBT and mindfulness-based therapies are classified as psychotherapeutic interventions, their methods are different. The purpose of CBT is to recognize negative thinking patterns and challenge them. It is systematic and goal-oriented (Nakao et al., 2021). Being present in the moment and embracing thoughts and feelings without judgment are stressed in mindfulness-based treatments, such as Mindfulness-Based Stress Reduction (MBSR) (Velissaris et al., 2023).
CBT is a highly successful treatment for GAD and gives patients useful tools to deal with certain fears (Nakao et al., 2021). Mindfullness-based approaches encourage overall well-being and might be helpful for people who want to create a more pervasive calm and lessen stress. However, although mindfulness approaches might take time to show obvious improvements and may require constant practice, the organized form of CBT may not appeal to everyone (Velissaris et al., 2023).
In conclusion, the selection of the treatment for GAD should be based on the patient’s preferences, the severity of their symptoms, and whether or not they have any co-occurring illnesses. While some people might find the most relief from medicine, others could gain the most from psychotherapy. The best course of action is frequently a customized plan that takes into account the particular requirements and circumstances of each GAD patient.
