Intrauterine Drug Delivery Systems01:21

Intrauterine Drug Delivery Systems

Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
Drug Accumulation During Multiple Dosing: Repetitive IV Injections01:21

Drug Accumulation During Multiple Dosing: Repetitive IV Injections

Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...
Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

Parenteral Drug Delivery Systems: Injectables, Implants, and Infusion Devices

Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...
Drug Accumulation During Multiple Dosing: Intermittent IV Infusions01:24

Drug Accumulation During Multiple Dosing: Intermittent IV Infusions

Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...

Summary

Supervised injecting facility (SIF) use may improve safer sexual practices among injection drug users (IDUs). Consistent condom use increased over two years, particularly with casual partners and among HIV-positive individuals.

Area of Science:

  • Public Health
  • Infectious Disease Epidemiology
  • Behavioral Science

Background:

  • Supervised injecting facilities (SIFs) are known to reduce injection-related risks.
  • The impact of SIFs on the sexual behaviors of injection drug users (IDUs) remains under-investigated.
  • Understanding condom use patterns among SIF users is crucial for harm reduction strategies.

Purpose of the Study:

  • To examine the patterns and predictors of consistent condom use among IDUs accessing a SIF in Vancouver, Canada.
  • To assess the longitudinal changes in condom use prevalence within this population.
  • To identify factors associated with safer sexual practices in the context of SIF utilization.

Main Methods:

  • A longitudinal analysis was conducted among IDUs recruited from a SIF.
  • Data on sexual behavior, including condom use, were collected over a two-year observation period.
  • Multivariate analysis identified predictors of consistent condom use with regular and casual partners.

Main Results:

  • At baseline, 25.3% of those with regular partners and 61.6% with casual partners reported consistent condom use.
  • After two years, consistent condom use increased to 32.9% and 69.8% for regular and casual partners, respectively.
  • HIV positivity was associated with increased condom use, while injecting with a sex partner, syringe borrowing, and syringe lending were associated with decreased condom use.

Conclusions:

  • Consistent condom use among SIF users, though initially low, increased significantly over time.
  • Higher rates of condom use were observed with casual partners and among HIV-positive individuals.
  • Findings suggest that SIFs may play a beneficial role in promoting safer sexual practices among IDUs.
