What is Acnedap 5% dapsone gel and how does it work?
Acnedap gel 5% made by reputable Cipla and contains the active ingredient dapsone, a sulfone component that is used as a topical treatment for acne vulgaris but is also used to treat serious infections like leprosy. Acne forms as a result of overstimulation of the sebaceous glands (oil producing glands in hair follicles). This often happens in response to a surge of androgen hormones at puberty and causes pores to become clogged with dead skin, leading to the formation of new pimples, whitehead and blackheads (comedones), which can become infected and inflamed.
Clogged pores attract bacteria which then overgrow and cause infection. Propionibacterium acnes are bacteria that normally exist on the skin without causing any problems, living on fatty acids in the sebum (oil) secreted by the sebaceous glands (oil producing glands in hair follicles of the skin).
Dapsone in Acnedap gel 5% is a sulfone antibacterial with anti-inflammatory actions and is thought to work by blocking the formation of dihydrofolic acid bacterial cells, a precursor for folic acid, which is needed for nucleic acid synthesis. This does not affect the host cells as only preformed folic acid is used in mammalian cells. This action of dapsone in Acnedap gel 5% kills the bacteria and prevents the spread of bacteria. Acnedap gel 5% is an effective and well-tolerated option for the topical treatment of acne vulgaris.
