Anafranil vs Paxil
Introduction
For patients with major depressive disorder (MDD) or other types of mental health conditions, certain drugs that regulate the concentrations of neurotransmitters in the brain can help manage symptoms and stabilize mood lows. Anafranil and Paxil are two such medications often prescribed for these purposes. They each target different neurotransmitters but both play a vital role in stabilizing moods in patients suffering from depression. Anafranil, also known as Clomipramine, is classified as a tricyclic antidepressant (TCA), which primarily affects levels of serotonin and to some extent norepinephrine. On the other hand, Paxil, more formally known as paroxetine, belongs to the class of selective serotonin reuptake inhibitors (SSRIs), impacting mainly levels of serotonin.
What is Anafranil?
Clomipramine (the generic name for Anafranil) is a tricyclic antidepressant (TCA), representing an earlier generation of antidepressants before the advent of selective serotonin reuptake inhibitors (SSRIs). Clomipramine was first approved by the FDA in 1981. It works to increase levels of free serotonin and norepinephrine, preventing them from being reabsorbed back into nerve cells in the brain. This leads to increased concentration and prolonged activity of these neurotransmitters, helping alleviate depressive symptoms.
Paroxetine (the generic name for Paxil), on the other hand, is a SSRI that came later than TCAs like Clomipramine. Paxil selectively inhibits serotonin reuptake with minimal effect on dopamine or norepinephrine absorption, making it more focused in its action and generally causing fewer side effects. Both medications are used to treat various forms of depression along with other mental health conditions; however their mechanisms and profiles differ due to advancements in understanding neurotransmitter activity over time.
What conditions is Anafranil approved to treat?
Anafranil is approved for the treatment of various mental health disorders:
- Obsessive-compulsive disorder (OCD)
- Major depressive disorder (MDD)
- Panic disorder, with or without agoraphobia
- Chronic pain associated with narcolepsy
On the other hand, Paxil has been approved for:
- Major depressive disorder (MDD)
- Social anxiety disorder
- Generalized anxiety disorder
- Post-traumatic stress disorder
- Obsessive-compulsive Disorder (OCD)
How does Anafranil help with these illnesses?
Anafranil, also known as clomipramine, helps manage obsessive-compulsive disorder (OCD) by increasing the amount of serotonin and norepinephrine available in the synapses of the brain. It does this by preventing these neurotransmitters from being reabsorbed back into nerve cells in the brain, thus prolonging their effects. Serotonin and norepinephrine are neurotransmitters that play key roles not only in mood regulation but also anxiety levels, concentration abilities, sleep patterns and feelings of well-being amongst other things. It is believed that individuals with OCD may have imbalances with these neurotransmitters. Therefore, Anafranil can help restore balance to these chemicals in the brain which then aids patients to better manage their OCD symptoms and improve overall mood stability.
What is Paxil?
Paxil is a brand name for paroxetine, which is a selective serotonin reuptake inhibitor (SSRI), meaning it increases the levels of serotonin in the brain by reducing its reabsorption. Paxil was first approved by the FDA in 1992 and has been used widely to treat major depression, obsessive-compulsive disorder, panic disorder, social anxiety, post-traumatic stress disorder and generalized anxiety disorders. Unlike drugs such as Anafranil (clomipramine), an older tricyclic antidepressant that affects multiple neurotransmitters including norepinephrine and acetylcholine receptors in addition to serotonin, Paxil's action is primarily on serotonin. This selectivity leads to a different side-effect profile compared to Anafranil; whereas the latter may cause anticholinergic effects like dry mouth or blurred vision due to its broader mechanism of action on various neurotransmitter systems. The focused effect on serotonin can make Paxil more tolerable for some patients than other "typical" tricyclic antidepressants like Anafranil.
What conditions is Paxil approved to treat?
Paxil is a selective serotonin reuptake inhibitor (SSRI) that has been approved by the FDA for the treatment of:
- Major depressive disorder
- Panic disorder, with or without agoraphobia
- Obsessive-compulsive disorder (OCD)
- Social anxiety disorder
- Generalized anxiety disorder
- Posttraumatic stress disorder (PTSD).
How does Paxil help with these illnesses?
Serotonin is a neurotransmitter which plays crucial roles in many processes within the body, affecting mood regulation, appetite, sleep, and cognition among others. Low levels of serotonin have been linked to depression. Much like other selective serotonin reuptake inhibitors (SSRIs), Paxil works by increasing the levels of available serotonin in the brain, contributing to mood elevation and alleviating some symptoms associated with depression. Its action on norepinephrine may also play a role in its antidepressant effect. Since it primarily targets serotonin rather than dopamine or acetylcholine systems, it's often prescribed when a patient does not respond well to tricyclic antidepressants (such as Anafranil) or can be combined with these medications under careful monitoring.
How effective are both Anafranil and Paxil?
Both clomipramine (Anafranil) and paroxetine (Paxil) are efficacious in treating depressive disorders, with the FDA approving their use within a year of each other. They operate on different neurotransmitters, which means they may be prescribed under varying conditions. A 1992 study directly investigated the effectiveness of Anafranil and Paxil in relieving depression; both drugs demonstrated similar efficacy in managing depressive symptoms along with comparable safety profiles. None of the multiple metrics used to gauge efficacy in treating depression differed between patients receiving Paxil or those getting Anafranil.
A 2003 meta-analysis review on clomipramine showed it kicks off its therapeutic effect from the first week of treatment, has a side effect profile that is more favorable than many other antidepressants and is well tolerated by various populations including elderly and pregnant women. The same study reports that clomipramine holds an essential place among tricyclic antidepressants worldwide due to its proven track record over time for treating obsessive-compulsive disorder as well as depression.
Paroxetine's review and meta-analysis conducted in 2015 suggested that it was significantly more effective than placebo at alleviating symptoms of depression while being similarly effective compared to most common antidepressants. Paroxetine is typically considered as a first-line treatment option when SSRIs are preferred because it has good tolerability profiles even though significant research indicates its co-prescription alongside another SSRI can lead to serotonin syndrome. Furthermore, evidence supporting paroxetine significantly augmenting effects from other antidepressants lacks robustness but due to its unique pharmacodynamic properties, Paxil might be optimal for patients who did not respond adequately to tricyclics or have specific needs such as avoiding anticholinergic side effects associated with older classes like TCAs.
At what dose is Anafranil typically prescribed?
Oral dosages of Anafranil start at 25 mg/day and may be increased gradually by your healthcare provider to a maximum of 200 mg/day, depending on the patient's response and tolerance. However, most individuals respond to 100-150 mg/day. For children and adolescents aged 10-17 years with obsessive-compulsive disorder (OCD), the starting dose is typically 25 mg per day with gradual increments, if necessary. The recommended dosage for this age group is typically no more than 3mg/kg or 200mg daily (whichever is less). In all cases, dosage adjustments should only be made under medical supervision to monitor side effects closely.

At what dose is Paxil typically prescribed?
Paxil treatment generally starts with a dosage of 20 mg/day taken orally. If necessary, the dose may be gradually increased by your healthcare provider up to 50 mg/day for depression or generalized anxiety disorder, divided into two doses spaced 12 hours apart. For panic disorder and obsessive-compulsive disorder (OCD), the maximum recommended dose is 60 mg/day. This higher dose could be considered if there's no response to initial treatment after several weeks. Always remember that any adjustment in dosage should only be made under the guidance of your healthcare provider.

- Symptoms of serotonin syndrome: agitation, hallucinations (seeing things that aren't there), fever/tachycardia/fast heartbeat, severe nausea/vomiting/diarrhea.
Remember to communicate with your doctor about any adverse reactions you experience— they are equipped to help adjust dosages accordingly to ensure safe usage.
Contraindications for Anafranil and Paxil?
Both Anafranil and Paxil, like most other antidepressant medications, can potentially exacerbate depressive symptoms in some individuals. If you notice an increase in the severity of your depression or a rise in suicidal thoughts or behaviors while taking these medications, it is crucial to seek immediate medical help.
Neither Anafranil nor Paxil should be taken if you are currently using or have recently discontinued monoamine oxidase (MAO) inhibitors. Please inform your doctor about any medication that you're presently consuming; MAOIs necessitate approximately 5 weeks without use to effectively eliminate from the body before starting treatment with either Anafranil or Paxil to avoid harmful drug interactions.
How much do Anafranil and Paxil cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Anafranil (25 mg) averages around $180, which works out to approximately $3/day depending on your dose.
- The price for 30 tablets of Paxil (20 mg) averages at about $130, working out to approximately $4.33/day.
Thus, if you are in the higher dosage range for Anafranil (i.e., 200 mg/day or more), then brand-name Paxil could be less expensive on a per-day treatment basis. Please remember that cost should not be the primary consideration in determining which medication is correct for you.
As for generic versions:
- Clomipramine HCL (Anafranil's generic version) costs between $0.26 and $1 per tablet with typical dosages ranging from 25mg to 200mg daily resulting in an approximate cost range from as low as$0.26 up to about $8 per day.
- Paroxetine HCL ER (generic form of Paxil) comes in packs starting from 10 capsules and more with prices ranging from around $.35 - $.80 per capsule making it roughly $.35 - $.80 cents a day based off recommended doses between one and two pills daily.
Costs mentioned above may vary significantly depending on individual health insurance coverage and location-specific pricing variations.
Popularity of Anafranil and Paxil
Clomipramine, available in brand form as Anafranil, was prescribed to approximately 600 thousand people in the US in 2020. Clomipramine accounts for roughly 1% of tricyclic antidepressant (TCA) prescriptions, a class of drugs that's been largely replaced by SSRIs and SNRIs due to their better side effect profiles. However, it remains a significant option for patients with obsessive-compulsive disorder (OCD), as it is one of the few medications found to be effective against this condition.
Paroxetine, known by its brand name Paxil among others, saw around 6 million prescriptions filled in the USA in 2020. This makes up about 12% of SSRI prescriptions and just over 5% of overall antidepressant prescriptions. The prevalence has decreased slightly over the last decade due to newer generation antidepressants gaining popularity but still maintains a large presence owing primarily to its efficacy across multiple mental health conditions including depression, anxiety disorders and OCD.
Conclusion
Both Anafranil (clomipramine) and Paxil (paroxetine) have been successfully used for many years in the treatment of depression, as well as other mental health disorders such as obsessive-compulsive disorder (OCD). Both drugs are backed by numerous clinical studies and meta-analyses indicating that they are more effective than placebo treatments. At times, these medications may be combined under careful supervision by a physician due to their drug interactions.
Anafranil is a tricyclic antidepressant that primarily acts on serotonin reuptake inhibitors but also affects norepinephrine receptors. On the other hand, Paxil is an SSRI which selectively inhibits serotonin uptake. This difference in action leads to varied prescribing situations with Anafranil being highly effective for OCD while Paxil generally serves as a first-line medication for major depressive disorder.
Generic versions of both drugs are available providing significant cost savings especially for patients who must pay out of pocket. The initiation phase for either drug might demand patience from patients since noticeable effects could take some time.
In terms of side effects, both drugs can cause nausea, dry mouth, or drowsiness but overall have good tolerability profiles. However, sexual dysfunction and weight gain can occur particularly with Paxil whereas Anafranil may lead to cardiac risks in certain individuals. Patients starting on any of these medications should closely monitor their moods and immediately seek medical help if there's worsening depression or emergence of suicidal thoughts or self-harm tendencies.
