The Food and Drug Administration has provided approval of Leqembi as a treatment option for mild to moderate Alzheimer’s disease. It works by blocking a specific enzyme responsible for the production of amyloid beta, a protein responsible for forming plaques in the brain, a hallmark of Alzheimer’s disease.

Leqembi is the first drug to receive approval for the blocking of amyloid beta plaque. The expectation is that it will significantly impact the treatment of Alzheimer’s. They project the cost of Leqembi to be relatively expensive because of the complexity of the drug and clinical trials.

What is Leqembi?

Leqembi is a new drug that has received FDA approval to treat Alzheimer’s. It’s an intravenous medication that helps reduce cognitive impairments associated with the disease.

It has been shown to improve cognition, memory, and thinking in clinical trials. The cost of the drug is expensive, but it may be covered by insurance depending on the plan.

How the Infusion treatment works

Infusion treatment is an effective and popular method of delivering Alzheimer’s treatments. This delivery method enables the body to absorb the desired substances more quickly and efficiently than the traditional oral route.

Infusion treatments involve the insertion of a small catheter or needle into a vein, typically located on the arm or hand. A sterile solution slowly moves through the catheter, which carries the desired substances directly into the bloodstream.

The process is monitored closely by experienced medical staff, and side effects are typically mild and transient. Infusion treatments are a safe and effective way to deliver medications and nutrients quickly and efficiently.

Leqembi’s approval is for adults with mild to moderate Alzheimer’s disease. Leqembi isn’t for those with severe forms of the disease. It should not be taken by individuals with certain conditions, such as those with a history of specific heart problems or certain types of cancer. It should not be combined with other medications to treat early Alzheimer’s disease.
