Description
Benzydamine hydrochloride is a non-steroidal anti-inflammatory drug used both topically and systemically. It possesses local anesthetic, analgesic, and antipyretic properties, making it a versatile pharmaceutical compound. It has been reported as a sensitizer and a photosensitizer, causing occupational contact dermatitis in some cases. The chemical properties of benzydamine hydrochloride are characterized by its off-white solid appearance, and it is commercially available under the brand name Tantum, manufactured by Angelini Francesco in Italy.
Uses
Used in Pharmaceutical Industry:
Benzydamine hydrochloride is used as an anti-inflammatory agent for its ability to reduce inflammation and provide pain relief. It is particularly effective in treating a range of painful conditions, such as aphthous ulceration, chemotherapy-induced mucositis, and radiation-induced mucositis.
Used in Dental Applications:
Benzydamine hydrochloride is used as a local anesthetic for its numbing effect on the oral tissues, making it suitable for dental procedures that require pain management and tissue anesthesia.
Used in Antipyretic Applications:
Benzydamine hydrochloride is used as an antipyretic agent to help reduce fever and alleviate the discomfort associated with elevated body temperatures.
Used in Anticholinergic Applications:
Benzydamine hydrochloride is used as an anticholinergic agent to block the action of acetylcholine, a neurotransmitter, in order to provide relief from certain conditions where the overactivity of acetylcholine is problematic.

Manufacturing Process
To a solution of 175 g of anthranilic acid methyl ester in 2 L of water and 120
ml of concentrated hydrochloric acid at 25°C was added concentrated solution
of 80 g sodium nitrite. The product was dissolved in solution of 500 g NaOH in
1.5 L of water. To this solution under nitrogen was added 400 g of sodium
bisulfite. The mixture was stirred for 6 hours at 75°C under nitrogen. The
obtained solid product was dissolved in water and then to the solution was
added 750 ml glacial acetic acid. The yield of 1-benzyl-3-(3-(dimethylamino)
propoxy)-1H-indazole 70%, M.P. 154-156°C.
In practice it is usually used as monohydrochloride salt.
Therapeutic Function
Analgesic, Antiinflammatory, Antipyretic
Contact allergens
It is a nonsteroidal anti-inflammatory drug used both
topically and systemically. It has been reported as a
sensitizer and a photosensitizer.
Side effects
The major side effects of benzydamine hydrochloride are oral numbness (reported prevalence: 10 percent), and oral burning/stinging (reported prevalence: 8 percent). Oral discomfort appears to be more of a problem in patients with extensive ulceration/infammation. The oral discomfort can sometimes be improved by diluting the benzydamine hydrochloride with an equal volume of water.It is thought that benzydamine hydrochloride does not precipitate peptic ulceration.
Safety Profile
Poison by
intraperitoneal, subcutaneous, and
intravenous routes. Moderately toxic by
ingestion. An experimental teratogen. Other
experimental animal reproductive effects.
An eye irritant. A nonsteroidal antiinflammatory
analgesic. When heated to
decomposition it emits very toxic fumes of
HCl and NOx.
Check Digit Verification of cas no
The CAS Registry Mumber 132-69-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 132-69:
(5*1)+(4*3)+(3*2)+(2*6)+(1*9)=44
44 % 10 = 4
So 132-69-4 is a valid CAS Registry Number.
