Study Notes
Hazard to Health
- Contaminated products can lead to varied health outcomes based on contamination type, degree, and intended use.
- Contaminated injections may cause severe consequences, including bacteraemic shock and death.
- Local infections can occur from wounds or broken skin, leading to extended hospital stays.
- Medicament-related infections often go unrecognized, contributing to prolonged infection spread.
Examples of Contaminants
- Gram-negative bacteria like Pseudomonas spp are notorious for causing outbreaks due to simple nutritional needs and growth in aqueous products.
- Contaminated ophthalmic solutions can lead to severe corneal infections and potential blindness.
- Skin infections in burn patients linked to contaminated antiseptic solutions can lead to graft failures and increased mortality.
- Contaminated ointments and creams have caused infections in eczematous skin and respiratory issues in neonates.
Factors Influencing Medicament Borne Infections
- Clinical reactions range from local to serious infections, heavily influenced by:
- Type and degree of microbial contamination.
- Route of administration.
- Patient's resistance to infections.
- Microorganisms in contaminated products can be classified as true pathogens or opportunistic pathogens.
Impact of Microbial Contamination
- True pathogens like Clostridium tetani can cause severe infections, while contaminated talcum powder can lead to neonatal deaths.
- Salmonella spp contamination has led to outbreaks due to ingestion of contaminated thyroid and pancreatic powders.
- Opportunistic pathogens, such as Pseudomonas, Klebsiella, and Serratia spp, are frequently found in medicinal products.
Pharmaceutical Product Introduction and Safety
- Pharmaceutical formulations consist of Active Pharmaceutical Ingredients (APIs) and excipients designed for:
- Enhanced manufacturability, stability, safety, effectiveness, and patient convenience.
- Products must adhere to stringent microbiological specifications, ensuring minimal microbial presence for non-sterile items.
- Occasionally, unacceptable levels of contamination may escape Quality Assurance checks, leading to:
- Product spoilage.
- Potential health hazards with outbreak risks.
- Financial losses due to wasted batches and product recalls.
- Opportunistic microorganisms primarily contribute to the spread of nosocomial infections among vulnerable patients.
