Qelbree is a once-a-day treatment for attention deficit hyperactivity disorder (ADHD) in adults and children 6 years of age and older. Qelbree is a non-stimulant ADHD medicine that may help to improve attention and reduce hyperactivity and impulsiveness. Qelbree is thought to work by increasing levels of norepinephrine, a chemical messenger found in the brain, by blocking a protein called pre-synaptic norepinephrine transporter. ADHD has been associated with low levels of norepinephrine, leading to symptoms such as hyperactivity, impulsivity, and lack of attention, so increasing norepinephrine levels may reduce ADHD symptoms. Qelbree is classified as a selective norepinephrine reuptake inhibitor (SNRI).  Qelbree’s FDA approval was received on April 2, 2021, and it is now indicated for the treatment of ADHD in adults and pediatric patients 6 years and older. Qelbree contains the active ingredient (which is sometimes referred to as the generic name) viloxazine.

Qlosi can be used daily, or as needed, up to twice per day and starts to improve near vision after 20 minutes and may last up to 8 hours. Qlosi is a preservative-free eye drop that is available in single-use vials.

This was based on positive results from phase 3 clinical trials NEAR-1 and NEAR-2. Qlosi showed a statistically significant 3-lines or more improvement in near vision, after 8 days, without the loss of 1-line or more in distance vision.

Salbutamol is a fast-acting bronchodilator and reliever medication. It belongs to a class of medications known as short-acting beta-2 adrenergic agonist. Salbutamol works by stimulating the beta-2 adrenoceptors in your bronchial muscles, which are the smooth muscles lining the two large tubes (bronchi) that carry air from your windpipe (trachea) to your lungs. This causes your bronchi to relax and dilate, widening your airway for a short period of about 4 to 6 hours and making it easier for you to breathe.

Saphnelo infusion is a prescription medicine used for moderate to severe systemic lupus erythematosus (SLE or lupus) in adults who are also receiving other lupus medicines.  Saphnelo (anifrolumab-fnia) works to reduce the body's immune and inflammatory response, to improve symptoms of SLE. Saphnelo is a monoclonal antibody that works by blocking type I interferon (INF-1) receptors. SLE is an autoimmune disease that causes pain and inflammation in your body. It is caused by your body’s immune system attacking healthy tissue instead of only fighting infections. Often SLE patients have elevated type I interferon stimulation which means too many unnecessary interferon signals are getting through, leading to inflammation in different parts of the body. Saphnelo blocks INF-1 receptors in the immune system, which decreases inflammatory signals and so improves the symptoms of SLE and reduces lupus flares. Saphnelo is not recommended for severe active lupus nephritis or severe active central nervous system lupus and is not approved for use by anyone younger than 18 years old Saphnelo infusion was FDA approved on July 30, 2021.
