Chloroquine
What is a Generic Drug?
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.

Product Details
Description
Chloroquine malaria treatment is a medication approved to prevent and treat malaria infection. It can also be prescribed to treat extraintestinal amebiasis.
Chloroquine is an anti-infective agent that works by binding to DNA and RNA polymerase in parasites. By blocking these proteins, chloroquine interferes with normal parasite metabolism. It also concentrates within the acid vesicles of parasites, causing a pH shift that impairs their growth.
Directions
The dosage of chloroquine depends on what is being treated. Take chloroquine exactly as prescribed by your doctor.
The usual doses are:
- Prevention of malaria: One Chloroquine 500 mg tablet by mouth once weekly, 1-2 prior to traveling to an area endemic with malaria. Continue weekly dosages for four weeks after leaving the area.
- Treatment of extraintestinal amebiasis: Two 500 mg (1000 mg total) on days 1-2, followed by 500 mg once daily for 2-3 weeks
- Treatment of malaria: Two 500 mg (1000 mg total) by mouth on day 1, then 500 mg 6, 24, and 48 hours after the first dose.
