About Desloratadine (Clarinex)

Desloratadine, marketed as Clarinex, is a nonsedating antihistamine effective in alleviating allergy symptoms such as sneezing, runny nose, and itchy eyes. It was developed as an active metabolite of loratadine and was approved by the FDA in 1993. Clarinex is available in various forms, including tablets and oral solutions, and works by blocking H1 histamine receptors. With a half-life of approximately 27 hours, it provides long-lasting relief for patients suffering from allergic rhinitis and chronic urticaria.

Properties of Desloratadine (Clarinex)

Desloratadine, known as Clarinex, is a tricyclic antihistamine with a molecular weight of 310.8 g/mol. It appears as a white to off-white powder, slightly soluble in water, but very soluble in ethanol and propylene glycol. Clarinex is available in light blue, round, film-coated tablets containing 5 mg of desloratadine. It has a rapid absorption rate, with peak plasma concentrations occurring around three hours after administration, which provides effective allergy relief for up to 24 hours.

Manufacturing Process of Desloratadine (Clarinex)

The production process of desloratadine, marketed as Clarinex, begins with the preparation of the starting material, loratadine. Loratadine is then reacted with a suitable alcohol, such as methanol, in the presence of an inorganic base like sodium hydroxide. This reaction is carried out at controlled temperatures ranging from 60 to 100°C. After the reaction is complete, excess water is added to the mixture, causing the desloratadine to precipitate in crystalline form. The crystalline desloratadine is then isolated by filtration, dried, and inspected to obtain the final product.

Synthesis of Desloratadine (Clarinex)

The production of desloratadine involves the following steps:

1.    Raw Materials

The primary raw materials required to produce desloratadine are:

• Loratadine

• Phosphorus oxychloride (POCl₃)

• Sodium hydroxide (NaOH)

• Solvents (e.g., methanol, toluene)

• Hydrochloric acid (HCl)

2.    Synthesis of Desloratadine

Step 1: Chlorination of Loratadine

Loratadine is chlorinated using phosphorus oxychloride (POCl₃) to produce deschlorocarbethoxy loratadine. The chemical reaction is as follows:

C₂₂H₂₃ClN₂O₂ (Loratadine) + POCl₃ → C₂₂H₂₂ClN₃ (Deschlorocarbethoxy Loratadine) + HCl + H₃PO₄

Step 2: Hydrolysis

Deschlorocarbethoxy loratadine is then hydrolysed using sodium hydroxide (NaOH) to produce desloratadine. The chemical reaction is as follows:

C₂₂H₂₂ClN₃ + NaOH + H₂O → C₁₉H₁₉ClN₂ (Desloratadine) + CH₃OH + CO₂ + NaCl

Step 3: Purification

The crude desloratadine is purified using recrystallisation or chromatography techniques to obtain a high-purity product.

Step 4: Conversion to Desloratadine Hydrochloride

Desloratadine is converted to its hydrochloride salt by reacting with hydrochloric acid (HCl). The chemical reaction is as follows:

C₁₉H₁₉ClN₂ + HCl → C₁₉H₁₉ClN₂·HCl (Desloratadine Hydrochloride)

3. Drying and Packaging

The purified desloratadine hydrochloride is dried to remove any remaining solvents or moisture. It is then packaged in appropriate containers for distribution.

Applications and Drivers of Desloratadine (Clarinex)

Clarinex is primarily used to treat allergic rhinitis and chronic idiopathic urticaria. Its applications extend to various formulations, including tablets and oral solutions, making it accessible for both adults and children. Additionally, emerging research suggests potential uses in treating acne as an adjunct to isotretinoin therapy. The key drivers for desloratadine's use include its efficacy in providing long-lasting relief without sedation, making it preferable for patients requiring daily allergy management.
