Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

1.5K
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...

Routes of Drug Administration: Parenteral

2.8K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

Insulin Formulations: Types and Delivery

663
Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
Short-acting insulins are divided into...

Drug Delivery: Miscellaneous Routes

716
Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection,  and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs...

Routes of Drug Administration: Overview01:22

Routes of Drug Administration: Overview

9.4K
Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Non-Oral Extravascular Drug Absorption Routes01:15

Non-Oral Extravascular Drug Absorption Routes

490
Non-oral extravascular routes, which encompass sublingual, buccal, topical, intramuscular, and inhalation methods, primarily utilize passive diffusion to transport drugs into the systemic circulation. The absorption rates and effectiveness of these routes depend on the drug's physicochemical properties, as well as the patient's anatomical and pathophysiological state.
Lipophilic drugs that are stable at salivary pH (6) and exhibit minimal binding to the oral mucosa are absorbed more...

Summary

Self-injectable contraception (DMPA-SC) offers higher continuation rates and user satisfaction compared to provider-administered injections. User autonomy and ease of self-administration are key factors in its effectiveness for family planning.

Area of Science:

  • Family Planning Research
  • Reproductive Health
  • Contraceptive Technology

Background:

  • Injectable contraception is a globally popular family planning method.
  • Depo medroxyprogesterone acetate-subcutaneous (DMPA-SC) allows for self-injection.
  • This review focuses on DMPA-SC research regarding continuation, safety, and satisfaction.

Purpose of the Study:

  • To review research on DMPA-SC effectiveness.
  • To evaluate continuation rates, safety, and user satisfaction with DMPA-SC.
  • To compare self-injection versus provider-injection methods.

Main Methods:

  • Review of emerging evidence from multiple countries (US, Malawi, Uganda, Senegal).
  • Analysis of studies evaluating DMPA-SC continuation rates.
  • Assessment of user satisfaction and ease of use data.

Main Results:

  • DMPA-SC demonstrates higher continuation rates (10-28%) among self-inject users compared to provider-inject users.
  • Self-injection with DMPA-SC is associated with high user satisfaction and ease of use.
  • User autonomy and self-administration appear to drive higher continuation rates.

Conclusions:

  • DMPA-SC should be accessible in both high- and low-resource settings.
  • Implementation strategies and cost-benefit analyses are crucial for DMPA-SC integration.
  • Future scale-up should consider task-shifting and mobile technology support for adherence.
