Nizoral shampoo general information
What is Nizoral shampoo used for?
Nizoral shampoo 2% is used to prevent and treat skin infections caused by the fungus malassezia (previously called Pityrosporum) which is a yeast normally found in the skin but can overgrow and cause problems like:
- Seborrhoeic dermatitis - dry or greasy scaling of the scalp and other parts of the body
- Tinea versicolor (pityriasis) - white to brown scaly patches on the body .
Nizoral shampoo 2% relieves the itching and scaling caused by this fungal infection.
How does Nizoral shampoo work?
Nizoral shampoo 2% contain ketoconazole, a synthetic broad-spectrum antifungal agent that specifically kills the fungus by inhibiting the synthesis of ergosterol, an important component of fungal cell membrane that is not found in animal cells. Nizoral shampoo weakens the fungal cell membrane, causing the cell contents to leak out which kills the fungus, preventing the spread infection from spreading and relieving symptoms like itching and scaling caused by the infection.
What does Nizoral Shampoo contain?
Each gram of Nizoral shampoo contains 20 mg of the active ingredient ketoconazole (2 % w/w) a synthetic broad-spectrum antifungal agent. Nizoral shampoo also contains sodium lauryl ether sulphate, disodium monolauryl ether sulphosuccinate, coconut fatty acid diethanolamide, laurdimonium hydrolysed animal collagen, macrogol 120 methyl glucose dioleate, sodium chloride, sodium hydroxide, imidurea, hydrochloric acid, erythrosine (E127) and purified water.
Treating dandruff with Nizoral Shampoo
Nizoral shampoo 2% contains ketoconazole, a synthetic broad-spectrum antifungal agent that specifically kills the fungus that causes dandruff, by inhibiting the synthesis of ergosterol, an important component of fungal cell membrane. The fungus malassezia (previously called Pityrosporum) is a yeast normally found in the skin but can overgrow and cause problems like dandruff, when the rate at which dead skin cells are shed and replaced begins to speed up, as a reaction to irritation by the fungus. Nizoral shampoo stops fungal growth and therefore relieves itchy scalp and the accumulation of white flakes in the hair and on the shoulders which are characteristic symptoms of dandruff,.
