Alopecia areata is an autoimmune malfunctioning disease that induces patchy hair loss on the scalp and sometimes in the facial hairs of bread, eyelashes, and eyebrows. In such baldness, the body’s immune cells attack the healthy follicles and damage them severely. This type of baldness is prevailing rapidly among all groups worldwide. The more vulnerable groups lie between 25 and 35 years. Individuals usually have flat circular patches of ample hairlessness that progress within a few weeks. In some cases, the restoration occurred after a few months. However, in some patients patchy hairlessness may keep on for a longer time and it can be a lifetime long.

There is an immense need for an effective recovery method that gives the best possible results and can be used long-term. These treatments should be safe for persons with chronic problems like diabetes and cancer. Ritlecitinib an innovative drug for the treatment of alopecia areata is a miraculous medication with an extensive success ratio. Most cases of AA are associated with bad quality of lifestyle and some psychological trauma (anxiety and depression). It belongs to the covalent kinase inhibitors group which hinders the selectivity of Janus kinase 3 (JAK3). It is a verified ground-breaking preparation that prevents the function of immune cells which degrade the follicle.

Mechanism of Action

The cytokine’s movement in and out of the immune cells plays a crucial role in immune homeostasis; they also create a signal of any immunological response. For the transmission of information from the external environment to the immune cell cytokines type I and II depend on the Janus kinase signal to code and decode the information. These traces might be impacted by any immune retort, hematopoiesis, and cell sequence parameter. Above fifty cytokines are related to the immune trace of patchy baldness by the JAK/STAT trail. Ritlecitinib is an innovative drug for the treatment of alopecia areata based on its effectiveness.

The Janus kinase enzymes work in pair form to conduct the signal originating from the outer environment to cytokine (I/II type) response conducted to the JAK enzymes, which produces a signal transducer and activator of transcription (STAT) this coding is translated to the nucleus which in response gives the command to the immune cells. These immune cells generate a long-term inflammation trigger in the hair follicles. AA disease is initiated by the T-cells of the immune system that leads to permanent baldness. By inhibiting the pathways of JAK/STAT the disease can be reversed simultaneously.

Ritlecitinib an innovative drug for the treatment of alopecia areata is the chief fellow of an innovative class that inhibits the activity of Janus kinase 3 (JAK3). This selective inhibition property makes it applicable to control follicular damages. The patient was treated with 50 mg or 30 mg Ritlecitinib on daily basis for 5 months. The recovery rate will be more than 20% which is quite remarkable.

Some Pathological Marks

It is a JAK3 inhibitor that can be taken orally. This medication is highly selective to inhibit the enzymes which trigger the t-cells of the immune system to degrade the hair follicle. This preparation is not sold in the market open, it is only administered on the advice of an experienced practitioner.  Still, the researchers are working to evaluate its potential in medicine field. Ritlecitinib an innovative drug for the treatment of alopecia areata has positive point that it can be administered orally unlike other potent managements. The remedy with the use of this medicine is much high after a few months of use the patient will observe the re-growth of the hairs in the affected area.  Commercially, there are fewer products used as JAK inhibitors in present times to suppress autoimmune disorders.

 Some undesired effects

As Janus kinase inhibitors let down the body’s immune system so the patient will be more prone to other infectious diseases. Ritlecitinib is an innovative drug for the treatment of alopecia areata as the individual’s immune system is suppressed intentionally. This drug should not give to a patient which has any chronic or acute infections. If any people have a 6-month previous history of infectious disease its use is prohibited.

·         The respiratory tract commonly upper track and nasal passages get infected.

·         Less reported infections are TB (tuberculosis) and oral candidiasis.

·         There will be a higher risk of cancer when used on a long-term basis.

·         The cholesterol levels of the patient may vary during its administration.

·         Blood clotting may occur which leads to other serious health issues like cardiovascular disorders.

·         Blood vessels may be blocked as thrombosis.

·         Liver harm is also a probable reaction to JAK inhibitor use.

Conclusion

This patchy follicular damage can be treated with 30–50 mg ritlecitinib on a daily recommended dose over 5 months. A visible recovery of 20% is observed within this time. Ritlecitinib is an innovative drug for the treatment of alopecia areata based on clinical outcomes. However, a deep precaution is needed because this medication suppresses the immune system of an individual. JAK inhibitors are produced selectively. It is more convenient to be administered orally. The researcher needs some more effort to investigate its long-term usage for hair restoration techniques.
