A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Nizoral 2% is a medicated dandruff shampoo that eliminates scalp dandruff and can be used for seborrheic dermatitis treatment. The active ingredient in this OTC dandruff shampoo - Ketoconazole - works by preventing Malassezia fungus from forming proper cell walls so that fungal growth cannot continue and result in worsening dandruff. This means less flakes on the scalp and being visible in hair, and users with chronic dandruff can use Ketoconazole shampoo to prevent dandruff.
You can buy Nizoral without a prescription, and your best price on it will be when you order medication online from Canada and Canpharm.
