Generic Paxil Cr Information

Introduction

Paxil Cr is a prescription antidepressant used primarily for the treatment of major depressive disorder and several anxiety‑related conditions. Its active ingredient is paroxetine, a selective serotonin reuptake inhibitor (SSRI) classified under the broader group of antidepressants. In Hong Kong, paroxetine‑containing products are regulated by the Department of Health and are available through licensed pharmacies. Besides depression, Paxil Cr is also approved for panic disorder, social anxiety disorder, obsessive‑compulsive disorder (OCD), generalized anxiety disorder (GAD), and post‑traumatic stress disorder (PTSD).

What is Paxil Cr?

Paxil Cr is a tablet formulation that delivers a fixed dose of the SSRI paroxetine. It is marketed as a generic version of Paxil, the original brand developed by GlaxoSmithKline, and contains the same active compound, dosage strength, and pharmacokinetic profile. Other well‑known brand names that contain paroxetine include Seroxat (Europe) and Brisdelle (menopausal hot‑flashes). Our online pharmacy supplies this generic alternative at a cost comparable to the manufacturer’s price, providing an affordable option for patients in Hong Kong.

Paroxetine was first synthesized in the 197s and received regulatory approval in the United States and Europe in the early 199s. Multiple generic manufacturers now produce paroxetine tablets that meet the quality standards set by the World Health Organization (WHO) and the Hong Kong Pharmaceutical Services Programme.

How Paxil Cr Works

Paroxetine belongs to the SSRI class, which modulates the synaptic availability of serotonin (5‑hydroxytryptamine, 5‑HT). Serotonin is a neurotransmitter involved in mood regulation, anxiety control, and perception of stress.

• Selective inhibition: Paroxetine binds reversibly to the serotonin transporter (SERT) on presynaptic neurons, blocking the re‑uptake of serotonin from the synaptic cleft.
• Increased extracellular serotonin: By preventing re‑absorption, the concentration of serotonin in the synapse rises, enhancing stimulation of postsynaptic serotonin receptors (especially 5‑HT₁A and 5‑HT₂A).
• Neuroadaptive changes: With continued exposure (typically 2–4 weeks), downstream signaling pathways adjust, leading to improved mood, reduced anxiety, and stabilization of affect.

Pharmacokinetic characteristics relevant to clinical use:

• Onset of therapeutic effect: Most patients notice clinical improvement after 2–3 weeks, with maximal benefit observed at 6–8 weeks.
• Half‑life: Approximately 21 hours, allowing once‑daily dosing.
• Metabolism: Primarily hepatic via CYP2D6 and CYP3A4; therefore, inhibitors or inducers of these enzymes can alter plasma levels.

Conditions Treated with Paxil Cr

Off‑label uses occasionally reported include menopausal hot‑flashes (Brisdelle formulation) and premature ejaculation, but these are not endorsed by Hong Kong regulatory authorities.

Who is Paxil Cr For?

Paxil Cr is appropriate for adult patients (≥18 years) who have been diagnosed with any of the approved indications listed above, provided they have no contraindications. Ideal candidates include:

• Individuals with a documented diagnosis of major depressive disorder or an anxiety disorder who have not responded adequately to non‑pharmacologic therapies (e.g., cognitive‑behavioral therapy).
• Patients requiring a once‑daily oral medication with a relatively long half‑life, which can improve adherence.
• Those seeking a cost‑effective alternative to brand‑name Paxil, especially when insurance coverage is limited.

Contraindications and situations where Paxil Cr is generally avoided:

• Known hypersensitivity to paroxetine or any tablet excipients.
• Concurrent use of monoamine oxidase inhibitors (MAOI) or within 14 days of MAOI discontinuation due to risk of serotonin syndrome.
• Severe hepatic impairment, as metabolism is predominantly hepatic.
• Pregnant women in the first trimester, given the FDA pregnancy category D classification (potential fetal risk).
• Adolescents and children, as efficacy and safety have not been established for this age group in Hong Kong.

Clinicians must evaluate comorbid medical conditions (e.g., cardiovascular disease,
