Summary of "Formulation, Development and Scale-Up of Fixed-Dose Combination Tablets Containing Zidovudine, Lamivudine and Nevirapine."

The development of antiretroviral associations in a single dosage form aims to ensure good efficacy, low costs and better adherence to treatment. Thereby, this work aimed to perform the pharmacotechnical development and stability studies of coated tablets of fixed-dose combination of zidovudine, lamivudine and nevirapine (300 + 200 + 150 mg, respectively). To develop the pharmaceutical form, the direct compression (DC) and wet granulation (WG) methods were tested, and the qualitative and quantitative planning of diluents (101 and 250 microcrystalline cellulose, spray dried monohydrate lactose and corn starch) and coating polymers (Opadry white II HP® and Instacoat Aqua Moistshield II®) were analyzed. Quality control was carried out according to the specifications set by official compendia. The chosen formulation was scaled-up and the industrial batches were submitted to accelerated and long-term stability studies. The batches obtained by WG met the requirements, using 101 microcrystalline cellulose, corn starch and Opadry white II HP® as excipients. The DC trial was not possible due to the need of a greater proportion of excipients to improve the characteristics of the drugs. Thus, this study brings a new therapeutic alternative for HIV treatment, offering another possibility to simplify drug administration.

Medical and Biotech [MESH] Definitions

A method of treating an ALLERGY by administering ALLERGENS, in liquid formulation or tablets, to the ORAL MUCOSA under the tongue.

The use of multiple drugs administered to the same patient, most commonly seen in elderly patients. It includes also the administration of excessive medication. Since in the United States most drugs are dispensed as single-agent formulations, polypharmacy, though using many drugs administered to the same patient, must be differentiated from DRUG COMBINATIONS, single preparations containing two or more drugs as a fixed dose, and from DRUG THERAPY, COMBINATION, two or more drugs administered separately for a combined effect. (From Segen, Dictionary of Modern Medicine, 1992)

Tablets coated with material that delays release of the medication until after they leave the stomach. (Dorland, 28th ed)

Single preparations containing two or more active agents, for the purpose of their concurrent administration as a fixed dose mixture.

A drug combination of fluticasone and salmeterol that is used as an inhaler formulation to manage the symptoms of ASTHMA and CHRONIC OBSTRUCTIVE PULMONARY DISEASE.
