What is Generic?

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.

Tobi is a cystic fibrosis lung infection treatment medication available by prescription, and it is administered as an inhalation. Tobramycin is part of the aminoglycoside class of antibiotics, and it is used when people with cystic fibrosis develop a pseudomonas aeruginosa infection and experience thick, stick mucus in their lung passageways. Using the Tobi Podhaler will result in the bacteria being unable to multiply and this weakening of the infection allows the immune system to gain the upper hand on it. Buy Tobi inhaled solution from Canada and Canpharm and get the best price on it.

What is a Pseudomonas Infection?

The pseudomonas aeruginosa bacteria are found in soil and water and can be spread to people through contaminated surfaces, hands, or equipment. For some people this will result in a very mild infection, but others will get a more serious infection and for people with cystic fibrosis the infection can be life threatening. The risk of these infections is higher for people who have a wound from surgery, are undergoing burn treatment, using a breathing machine or catheter, or have diabetes, cystic fibrosis, or immune system disorders like HIV.

Frequently Asked Questions about Tobramycin

Is Tobramycin a strong antibiotic?

It is a strong antibiotic, and that strength is required in order for the medication to be able to knock out pseudomonas aeruginosa bacteria as they are an especially hardy strain that will be able to maintain strength if a weaker antibiotic drug is used for treatment.

How fast does Tobramycin work?

Users can expect to see reduced pseudomonas aeruginosa infection symptoms with less heavy mucus congestion within 10 days to 2 weeks of starting to use the inhaler.

Should Tobramycin be refrigerated?

Yes, you should store the capsules in the refrigerator between 2 and 8 degrees Celsius and keep them out of light and reach of children.

What is the Tobramycin inhalation schedule?

Users of this medication will take 2 inhalations a day for 28 days, and then this is followed by a matching 28-day (4 week) period where they do not take the medication and gauge the effectiveness of it and whether or not the pseudomonas aeruginosa infection has cleared. If not, a new 28-day treatment schedule can begin with the same 4-week on / 4-week off guideline.
