Paraxyl Cr Tab 25mg, containing paroxetine HCl as its active ingredient, is a medication for managing mental health conditions such as depression, GAD, panic disorder, and social anxiety disorder. As an SSRI, paroxetine HCl works by increasing the availability of serotonin in the brain. Serotonin is a neurotransmitter that plays a vital role in regulating mood, emotions, and mental well-being. By inhibiting the reuptake of serotonin, paroxetine HCl helps maintain higher levels of serotonin in the brain, promoting a more stable mood and reducing symptoms associated with depression and anxiety. This mechanism of action assists in restoring the balance of neurotransmitters in the brain.
