Learn all about Imiquimod cream which is used for the treatment of warts and . There are two strengths of Imiquimod cream available 3.75% (brand name Zyclara) and 5% (brand name Aldera).

Imiquimod (INN) is a prescription medication that acts as an immune response modifier and is used to treat genital warts, superficial basal cell carcinoma, and actinic keratosis. Scientists at 3M’s pharmaceutical division discovered Imiquimod as part of a program to discover inhibitors of herpes virus replication based on a known adenine derivative. 3M obtained the first FDA approval for it in 1997 as a treatment for external genital and perianal warts under the brand, “Aldera”. In 2004 3M obtained FDA approval to market Imiquimod as a treatment for superficial basal cell carcinoma.

In 2006, 3M sold its pharmaceutical business in the Americas to Graceway Pharmaceuticals. Graceway declared bankruptcy in 2011 after the expiration of the patents on Imiquimod, and its assets, including the rights to Imiquimod branding and approvals in the Americas were purchased by Medicis Pharmaceutical. As of 2015, Imiquimod is generic and is available worldwide under many brands.

Imiquimod works by stimulating the immune system to release a number of chemicals called cytokines, which are important in fighting viruses and destroying cells. When used to treat skin cancers and pre-cancerous lesions it results in inflammation, which destroys the lesion. The degree of inflammation is quite variable from person to person, in part due to the type of skin lesion and in part due to genetic factors. The Imiquimod is taken up by the so-called ‘toll-like receptor 7’ on certain immune cells that are found in the outside part of the skin (the epidermis); these receptors are expressed more in some individuals and in some skin lesions than in others.

Treatment is sometimes continued for up to 16 weeks. Treatment should be carefully monitored, because the cream may need to be applied more or less frequently than originally planned or for a shorter or longer course, depending on response. Once the inflammation has settled there is generally a good or excellent cosmetic result with little scarring. Areas treated with Imiquimod will become inflamed. The effects include itching, burning, redness, ulceration (sores), scabbing, flaking and pain. These reactions indicate that the cream is likely to be effective.
