Terms & Conditions of Program
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.
A535 Rub is an over-the-counter topical analgesic indicated for the temporary relief of muscle and joint pain associated with strains, sprains, arthritis, and backaches. It contains counterirritant and analgesic agents that produce a warming or cooling sensation to help alleviate pain by distracting from deeper muscular discomfort. A535 Rub is available in several formulations, including regular, ultra-strength, and no-odour versions, designed for external use only. It is a commonly used product in sports medicine and home care settings for short-term symptomatic pain management.
