INTRODUCTION

Ciclopirox Olamine (CPO)  is the N-oxide of a 2 -hydroxy pyridine derivative that carries antifungal, antibacterial, and anti-inflammatory properties. It is composed of 6-cyclohexyl-1-hydroxy-4-methyl-2(1H)-pyridone combined with 2 aminoethanol (olamine) in a 1:1 ratio. It works through a multifaceted mechanism of action that primarily disrupts the fungal cell’s metabolic function by inhibiting  essential enzymes through its ability to create  large polyvalent cation  through chelation. It exhibits antibacterial, anti-inflammatory and antifungal properties, hence often formulated as cream, lotion, or nail lacquer.

Manufacture

CPO is manufactured by reacting Ciclopirox base with equimolar ethanolamine in a suitable solvent under controlled temperature to form the salt.The product is then crystallized, filtered, washed, and dried to obtain the final active pharmaceutical ingredient.

Structure

Applications

CPO  is a versatile and effective antifungal agent with a well-established safety profile. Its ability to disrupt fungal cell metabolism and membrane integrity makes it a valuable treatment option for a range of fungal infections.

It is commonly formulated in creams, lotions, gels, shampoos, and nail lacquers.
It is used primarily in treatment of fungal infections of the skin, including tinea corporis (ringworm), tinea cruris(jock itch), tinea pedis (athlete’s foot), and the nails (onychomycosis).
Clinically, ciclopirox 1% cream, lotion, and 0.77% topical suspension are indicated for the treatment of cutaneous candidiasis.
In dosage of 0.7 %– 1.6% it provides relief of symptoms such as itching, redness.
It  exerts its anti-inflammatory activity by inhibiting 5-lipoxygenase and cyclooxygenase (COX).
Ciclopirox Olamine can be used to study the regulatory mechanisms of metal homeostasis in cells and its effects on cellular processes.
