Nevertheless, these are much lower when compared to oral medications. Irritation occurs on the skin as a sign of the ill effect.  As we talked about the sensitivity for sunlight above, we shall talk about the vitamin D analogues. The vitamin D in it’s a synthetic form reduces cell growth. When exposed to sunlight, vitamin D absorption increases. This makes the skin cells overproduction reduce. There are various forms of vitamin D like solutions, creams which need a prescription for its usage. Calcipotriene drug called Dovonex and calcitriol drug known as vectical are the vitamin D analogues available for treating psoriasis. For milder psoriasis, Dovonex is prescribed. This irritates the skin as a side effect. Vectical is very less irritating when compared to the Dovonex. But it is more pricey. To reduce the inflammation and piling up of the plaque and scales calcineurin inhibitors such as tacrolimus and pimecrolimus for a few days dosage.

But this brings along with it the risks of cancers, high blood pressure, renal diseases. Hence only a short term usage of the drug is prescribed.

The other drugs that act as the immune system are the biologics. They are injected when the psoriasis is severe, or moderate. They strongly act on the immune system hence they should be taken on prescription and caution. Side effects are life-risking diseases. Psoriasis arthritis patients can take these injections. Pregnant and people with pulmonary diseases are exceptional from this.

Another new treatment approach is biosimilars, that are similar to biological but reversible in function nevertheless with the same results. They are made to be as an affordable replacement to the biologics. A few examples for the biosimilars are inflectra, Remicade, which is similar to infliximab, amjevita and cyltezo similar to Humira. Etalizumab has been a drug in usage for a long while in the market. It was targeted against the LFA-1 though it was most efficient in it’s a way to treat severe psoriasis, due to lifeline-risking effects it has been withdrawn from the market.

Upcoming new treatments under development are ISA247 called cyclosporin, this is a calcineurin inhibitor which is without the current side effects. This has shown very few drawbacks than the usual calcineurin inhibitor. BZ-423 is another benzodiazepine drug, that has been approved for psoriasis treatments. It targets the cells and causes cell death by a complex signalling pathway, this is under research yet.
