绥美凯治什么呢？

It is a compound preparation. Each tablet contains 50 mg of dolutegravir sodium (calculated as dolutegravir), 600 mg of abacavir sulfate (calculated as abacavir) and 300 mg of lamivudine. It is suitable for the treatment of adults infected with human immunodeficiency virus (HIV) and adolescents over 12 years old (with a weight of at least 40 kg). Among them, dolutegravir can inhibit HIV integrase by binding to the active site of integrase and blocking the strand transfer step of reverse transcription deoxyribonucleic acid (DNA) integration (a key step in the HIV replication cycle).

For adults and adolescents, the recommended dose of Trimax is one tablet once daily. Adults or adolescents whose body weight is less than 40 kg should not be given this product because this product is a fixed-dose tablet and the dose cannot be reduced. Trimax is a fixed-dose tablet and should not be used in patients who require dose adjustments. If one of the active ingredients needs to be discontinued or a dose adjustment is required, separate formulations of dolutegravir, abacavir, or lamivudine may be used. In these cases, physicians should refer to the respective product information for these medicines.

Things to note:

Mitochondrial dysfunction following in utero exposure

Nucleosides and nucleoside analogs may affect mitochondrial function to varying degrees, with the effects being most significant when combined with stavudine, didanosine, and zidovudine. Mitochondrial dysfunction has been reported in HIV-negative infants exposed to nucleoside analogues in utero and/or postnatally, primarily in association with zidovudine-containing treatment regimens. The main adverse reactions reported were hematological disorders (anemia, neutropenia) and metabolic disorders (hyperlactemia, hyperlipidemia). These reactions are often short-lived. Some late-onset neurological disorders (hypertonia, convulsions, behavioral abnormalities) are rarely reported. It is unclear whether the neurological condition is temporary or permanent. These results should be considered in children exposed to nucleosides and nucleoside analogues in utero who have severe clinical symptoms of unknown etiology, especially neurological symptoms. These results do not affect current national guidelines for the use of antiretrovirals in pregnant women to prevent vertical transmission of HIV.

myocardial infarction

Observational studies have demonstrated an association between myocardial infarction and abacavir use. The patients participating in the study were mainly those who had received antiretroviral therapy. Clinical trial data show a limited number of myocardial infarctions and a small increase in risk cannot be ruled out. Overall, there are some inconsistencies between observational cohort data and randomized trial data, so a causal relationship between abacavir treatment and the risk of myocardial infarction cannot be confirmed or denied. To date, there is no precise biological mechanism to explain the possible increased risk. When using this product, steps should be taken to minimize all modifiable risk factors (such as smoking, hypertension, and hyperlipidemia).

osteonecrosis

Although the etiology is thought to be multifactorial (including use of corticosteroids, bisphosphonates, alcohol consumption, severe immunosuppression, and high body mass index), cases of osteonecrosis have been reported, particularly in patients with advanced HIV disease and/or long-term exposure to CART. Patients should be advised to seek medical attention if they experience joint pain, joint stiffness, or difficulty moving.

Opportunistic infections

Patients should be informed that HIV infection cannot be cured by this product or any other antiretroviral therapy and that they may still develop opportunistic infections and other complications of HIV infection. Therefore, patients should be under close clinical observation by physicians experienced in treating HIV-related diseases.

Resistant

Because the recommended dose of dolutegravir in patients who are resistant to integrase inhibitors is 50 mg twice daily, its use in patients who are resistant to integrase inhibitors is not recommended.
