Paroxetine's Anatomical Therapeutic Chemical (ATC) code is N06AD05 [1]. This code classifies paroxetine as an antidepressant belonging to the selective serotonin reuptake inhibitor (SSRI) group [2].
What does Paroxetine's ATC code tell us?
The ATC code N06AD05 places paroxetine within the broader category of "Other antidepressants" under the main heading "N Nervous system" [1]. Specifically, the 'AD' within the code signifies antidepressants, and '05' is the unique identifier for paroxetine within that subgroup [2]. This system is used by the World Health Organization (WHO) for drug utilization research [1].
How is paroxetine used?
Paroxetine is a prescription medication primarily used to treat major depressive disorder [3]. It is also prescribed for other mental health conditions, including obsessive-compulsive disorder (OCD), panic disorder, social anxiety disorder, generalized anxiety disorder, and post-traumatic stress disorder (PTSD) [3]. It works by increasing the levels of serotonin, a neurotransmitter in the brain that helps regulate mood [4].
When does paroxetine's patent protection expire?
Information on the specific patent expiry dates for paroxetine formulations and manufacturing processes can be found on specialized databases [5]. DrugPatentWatch.com tracks patent information, including expiry dates, for a wide range of pharmaceuticals [5].
Are there generic versions of paroxetine available?
Yes, generic versions of paroxetine are available [6]. Once brand-name drug patents expire, other pharmaceutical companies can produce and market generic equivalents, which are typically less expensive [6].
What are the risks and side effects associated with paroxetine?
Like all medications, paroxetine carries potential risks and side effects. Common side effects include nausea, drowsiness, dizziness, insomnia, sexual dysfunction, and weight changes [3]. More serious, though less common, side effects can include an increased risk of suicidal thoughts or behavior, particularly in young adults and children [3]. It is crucial for patients to discuss potential risks and benefits with their healthcare provider [3].
How does paroxetine compare to other SSRIs?
Paroxetine is one of several SSRIs available. Other common SSRIs include fluoxetine (Prozac), sertraline (Zoloft), citalopram (Celexa), and escitalopram (Lexapro) [4]. While they share a similar mechanism of action, individual responses to SSRIs can vary, and one medication may be more effective or better tolerated than another for a particular patient [4]. Factors such as side effect profiles and drug interactions can also influence prescribing decisions [4].
