What are the key excipient strategies for allergy and congestion relief drugs?
Excipient selection influences drug stability, bioavailability, taste masking, and patient compliance. For allergy and congestion relief formulations, excipients are tailored based on the delivery form—tablets, liquids, or nasal sprays.
Tablet formulations
- Binders and fillers: Microcrystalline cellulose (MCC), lactose, microfine calcium carbonate; ensure tablet integrity.
- Disintegrants: Croscarmellose sodium, sodium starch glycolate; promote rapid dissolution.
- Lubricants: Magnesium stearate; facilitate manufacturing.
- Coating agents: Hydroxypropyl methylcellulose (HPMC); control release and mask taste.
Liquid formulations
- Solvents and carriers: Purified water, propylene glycol; dissolve active ingredients.
- Sweeteners and flavoring agents: Sucralose, citric acid; improve taste and stability.
- Preservatives: Benzalkonium chloride; inhibit microbial growth.
Nasal spray formulations
- Buffer agents: Phosphate buffers; maintain pH compatible with mucosa.
- Vimulinizing agents: Benzalkonium chloride, polysorbates; act as preservatives and enhance adhesion.
- Viscosity modifiers: Carboxymethylcellulose sodium; prolong nasal residence time.
