Guanidine exists protonated, as guanidinium, in solution at physiological pH. Guanidinium chloride (also known as guanidine hydrochloride) has chaotropic properties and is used to denature proteins. Guanidinium chloride is known to denature proteins with a linear relationship between concentration and free energy of unfolding.
This dosage may be gradually increased to a total daily dosage of 35 mg/kg (16 mg/pound) of body weight per day or up to the development of side effects. Side effects may include increased peristalsis, diarrhea, paresthesia (tingling and numbness), and nausea. Fatal bone-marrow suppression, apparently dose related, can occur with guanidine. [7]
Guanidinium thiocyanate can be used to deactivate a virus, such as the influenza virus that caused the 1918 "Spanish flu", so that it can be studied safely.. Guanidinium thiocyanate is also used to lyse cells and virus particles in RNA and DNA extractions, where its function, in addition to its lysing action, is to prevent activity of RNase enzymes and DNase enzymes by denaturing them.
The last of these is not pre-formulated, but rather is generated at the time of use by combining a cream containing calcium hydroxide (slaked lime) with an "activating solution" of guanidine carbonate. Another type of "no-lye" relaxer uses ammonium thioglycolate, which is also known as perm salt for its use in permanent waves.
Pimagedine, also known as aminoguanidine, is an investigational drug for the treatment of diabetic nephropathy that is no longer under development as a drug. [1] Pimagedine functions as an inhibitor of diamine oxidase and nitric oxide synthase.
An equianalgesic chart is a conversion chart that lists equivalent doses of analgesics (drugs used to relieve pain). Equianalgesic charts are used for calculation of an equivalent dose (a dose which would offer an equal amount of analgesia) between different analgesics. [1]

Their therapeutic uses derive from their tendency to reduce gluconeogenesis in the liver, and, as a result, reduce the level of glucose in the blood. Biguanides also tend to make the cells of the body more willing to absorb glucose already present in the bloodstream, and there again reducing the level of glucose in the plasma. [citation needed]
