Mechanism of Action

Clindamycin works by inhibiting bacterial protein synthesis through binding to the 50S ribosomal subunit of bacteria, thereby preventing bacterial growth. Benzoyl peroxide acts as an antimicrobial agent by releasing oxygen, which kills the bacteria responsible for acne. Additionally, benzoyl peroxide helps to exfoliate the skin, reducing clogged pores.

How Long Does It Take to Work?

Patients may start to see improvements in their acne within 2 to 4 weeks of starting treatment, with more significant results often occurring after 6 to 8 weeks of use. The full benefits of the medication can be observed over several months of consistent application.

Absorption

When applied topically, clindamycin and benzoyl peroxide are absorbed through the skin but generally have minimal systemic absorption. Their primary action is localized to the area of application, focusing on the skin's surface and upper layers.

Route of Elimination

Clindamycin is metabolized in the liver and excreted primarily in the urine. Benzoyl peroxide is broken down in the skin and has minimal systemic absorption, with its breakdown products also excreted through urine.

Dosage

Adults and Adolescents (aged 12 years and above): This gel should be applied once daily in the evening, to the entire affected area. Patients should be advised that excessive application will not improve efficacy, but may increase the risk of skin irritation. If excessive dryness or peeling occurs, frequency of application should be reduced or application temporarily interrupted. An effect on inflammatory and non-inflammatory lesions may be seen as early as week 2-5 of treatment. The safety and efficacy of this gel has not been studied beyond 12 weeks in acne vulgaris clinical trials. Treatment with this gel should not exceed more than 12 weeks of continuous use.

Paediatric population: The safety and efficacy of this gel has not been established in children under 12 years of age, therefore this gel is not recommended for use in this population.

Elderly patients: No specific recommendations. This gel should be applied in a thin film after washing gently with a mild cleanser and fully drying. If the gel does not rub into the skin easily, too much is being applied. Hands should be washed after application.

The usual dosage of clindamycin + benzoyl peroxide is:

Apply a thin layer of the medication to the affected areas of the skin once or twice daily, as prescribed by a healthcare provider.
Follow the specific dosing instructions provided by a healthcare professional or as indicated on the medication label.

Dryness or peeling of the skin.
Redness or irritation at the application site.
Itching or burning sensation.

History of gastrointestinal conditions, as systemic absorption of clindamycin can be a concern if there is significant irritation.
Severe skin conditions or eczema, as benzoyl peroxide may exacerbate irritation.

Drug Interaction

No significant drug interactions are known with clindamycin + benzoyl peroxide. However, patients should inform their healthcare provider of all other topical or oral medications they are using to avoid potential interactions.

Food Interactions
