Are you struggling to reach your weight loss goals? In today’s article, we’re going to dive into the fascinating world of Naltrexone and Bupropion, two drugs that, when combined, can work wonders for shedding those extra pounds.
A Unique Combination of Two Drugs
Naltrexone is an opioid antagonist, while Bupropion is an atypical antidepressant. Although they belong to different chemical and clinical categories, they can be combined into a single tablet. This combination, available in extended-release form, is used to manage chronic obesity in patients with a body mass index (BMI) of 30 or higher. It can also be effective for controlling overweight in patients with a BMI greater than 27 who have cardiovascular risk factors.
How Does the Combination Work?
Within the central nervous system, dopamine plays a crucial role in appetite control. Bupropion, by blocking dopamine transporters, increases dopamine transmission. This leads to the activation of POMC neurons, which store precursor peptides that control appetite. Alpha-MSH, one of the peptides released from POMC, acts on melanocortin-4 receptors in the hypothalamus, reducing appetite and increasing energy consumption.
On the other hand, beta-endorphin, another peptide released from POMC neurons, plays an opposing role. It acts on mu receptors, inhibiting POMC activity. Naltrexone, an opioid antagonist, blocks these mu receptors, enhancing the activity of POMC and reducing appetite. Together, the combination of Bupropion and Naltrexone effectively tackles obesity by controlling appetite and promoting weight loss.
Precautions and Possible Side Effects
While this combination can be highly effective, there are important precautions to consider. Patients with a history of seizures should use caution when taking this combination, as it may induce seizures. It should also be used with care in patients using CNS stimulants, those with a history of head injury or stroke, and those with alcohol withdrawal symptoms. Additionally, it should be used cautiously with opioids to avoid opioid intoxication.
Possible side effects include constipation, nausea, vomiting, headache, dizziness, insomnia, dry mouth, fatigue, tremors, hypertension, abdominal pain, tinnitus, excess sweating, and allergic reactions such as pruritus and urticaria. Patients should be aware of these potential side effects and seek medical attention if necessary.
Administration and Dosage
The combination is available as an extended-release tablet containing Naltrexone HCl and Bupropion HCl. The initial dose of Naltrexone is 8 mg and Bupropion is 90 mg. The dosage is gradually increased over four weeks, starting with one tablet in the morning in the first week and one tablet in the evening in the second week. The dosage escalates to two tablets in the morning and one in the evening in the third week, and finally, two tablets in the morning and two in the evening in the fourth week.
The maximum dosage is 32 mg of Naltrexone and 360 mg of Bupropion. It is important to continue the therapy until the desired effectiveness is achieved.
Say Goodbye to Excess Weight
The combination of Naltrexone and Bupropion is a powerful tool in the battle against obesity. By controlling appetite and promoting weight loss, this combination offers hope to those struggling with chronic obesity. Remember, always consult with your healthcare provider before starting any weight loss program.
