With vast industrial knowledge and deep market understanding, we are engaged in offering Promethazine Hydrochloride. This drug is an osmotic diuretic, metabolically inert in humans and occurs naturally, as a sugar or sugar alcohol, in fruits and vegetables. The drug elevates blood plasma osmolality, resulting in enhanced flow of water from tissues into interstitial fluid and plasma. Promethazine Hydrochloride may also be used for the promotion of diuresis before irreversible renal failure becomes established. It also helps in the promotion of urinary excretion of toxic substances and as a renal function diagnostic aid.
