Quinine urea mixture is a long-acting local anesthetic and analgesic. However, the quinine-urea mixture could delay wound healing if directly injected into wound edges. A syringe with a long offset needle such as Moynihan’s for infiltrating “at a Distance from the Incision.” is recommended for quinine urea delivery.

Quinine soluble salts possess an extremely bitter taste, that may have a perplexing problem especially to children. That is why one of the most common combinations for oral administration is a slightly soluble quinine salicylate salt. It is known that now quinine is used in the absence of artemisin combination therapies (ARTs) to treat CQ resistant (CQR) P. falciparum malaria. Although the precise mechanism of the antimalarial activity of quinine is not completely understood, it can act via the inhibition on nucleic acid synthesis, on protein synthesis, and on glycolysis in Plasmodium falciparum, and also drug can affect via the binding with hemazoin in parasitized erythrocytes.

Quinine ascorbate is a salt of antimalarial drug quinine and ascorbic acid (vitamin C). Ascorbate reduces the potency of quinolone-containing anti-malarial drugs. Quinine ascorbate was marketed as a component of over-the-counter smoking deterrent products but was not recognized as safe by the FDA regulation in 1993.

Quinine iodosulfate (herapathite) is a mixed salt of quinine and iodine. Its crystals are dichroic - they function as excellent linear light polarizers absorbing virtually all the light polarized along the shorter axis of the best-developed face. A sheet of quinine iodosulfate sandwiched between two glass plates is called polaroid. Polaroids find applications in areas such as automobile headlights and windscreens, hotel and aircraft windows and sunglasses.

QUININE PHOSPHATE, a salt of quinine, was formerly used for the treatment of malaria.

Quinine soluble salts possess the extremely bitter taste, that may have a perplexing problem especially to children. That is why the most common combinations which are administered in this way are the sulphate, salicylate, tannate and certain esters. Quinine tannate, an insoluble quinine salt has been known in medicine for a very long time. However, many experiments have revealed that quinine tannate was practically inert as a medicinal substance.
