1. Oral administration:
- Convenient and easy to administer, especially for patients who have difficulty with injections or other routes of administration.
- Allows for slow and controlled release of the drug into the bloodstream, leading to sustained therapeutic effects.
- Can be taken with food or drink, which can help mask the taste of bitter medications.
- Generally less invasive and associated with fewer side effects compared to other routes of administration.
2. Intravenous administration:
- Provides rapid onset of action, making it ideal for emergency situations or when immediate effects are needed.
- Allows for precise control over the dosage and rate of administration, ensuring accurate delivery of the drug.
- Bypasses the first-pass metabolism in the liver, leading to higher bioavailability of the drug.
- Suitable for patients who are unable to take medications orally or have gastrointestinal absorption issues.
3. Intramuscular administration:
- Allows for sustained release of the drug into the bloodstream, leading to prolonged therapeutic effects.
- Suitable for drugs that are poorly absorbed orally or have a short half-life.
- Can be used to administer larger volumes of medication compared to other routes of administration.
- Provides a more consistent and predictable absorption profile compared to oral administration.
4. Subcutaneous administration:
- Provides a slower onset of action compared to intravenous administration, making it suitable for drugs that require a more gradual release into the bloodstream.
- Can be self-administered by patients, reducing the need for frequent visits to healthcare providers.
- Suitable for drugs that are irritant to the veins or require a smaller volume of injection.
- Allows for sustained release of the drug, leading to prolonged therapeutic effects.

Oral Administration
- Convenience: Easy and convenient for patients to take.
- Cost-effectiveness: Relatively inexpensive compared to other routes.
- Wide range of drugs available: Most drugs can be formulated for oral administration.
- Self-administration: Patients can take their medication independently.
Subcutaneous Administration
- Controlled absorption: Drugs are absorbed more slowly and over a longer period of time, providing a sustained release.
- Easy access: Suitable for patients who have difficulty swallowing or who are unconscious.
- Avoids first-pass metabolism: Drugs bypass the liver, reducing their metabolism and increasing bioavailability.
Intramuscular Administration
- Rapid onset of action: Drugs absorb more quickly than with other routes.
- Higher bioavailability: Drugs reach higher concentrations in the bloodstream compared to oral administration.
- Sustained release formulations: Can provide a prolonged effect.
Intravenous Administration
- Immediate effect: Drugs are directly injected into the bloodstream, providing the most rapid onset of action.
- Controlled dosage: Allows for precise administration and titration of the drug dose.
- Bypasses barriers: Drugs reach target tissues quickly and effectively, bypassing the digestive tract and other barriers.
Transdermal Administration
- Convenience and comfort: Patches or creams can be applied to the skin, allowing for easy and painless administration.
- Sustained release: Drugs are released gradually over a period of time, providing a prolonged effect.
- Avoids first-pass metabolism: Drugs enter the bloodstream directly through the skin, reducing their metabolism.
Inhalation Administration
- Rapid onset of action: Drugs are inhaled directly into the lungs, providing nearly instantaneous effects.
- Target specific areas: Certain inhalation devices can deliver drugs to specific regions of the respiratory tract.
- Convenience: Inhalers are portable and easy to use, making them suitable for self-administration.
Ophthalmic Administration
- Local effect: Drugs are applied directly to the eye, providing targeted treatment.
- Avoids systemic effects: Drugs are less likely to enter the bloodstream, reducing the risk of side effects.
- Rapid onset of action: Drugs act quickly when applied to the eye.
Rectal Administration
- Bypasses first-pass metabolism: Drugs avoid the liver, increasing their bioavailability.
- Convenient for unconscious or immobilized patients: Can be administered when other routes are not suitable.
- Controlled release formulations: Suppositories can provide a sustained effect.
- Convenience: Easy and convenient for patients to take.
- Cost-effectiveness: Relatively inexpensive compared to other routes.
- Wide range of drugs available: Most drugs can be formulated for oral administration.
- Self-administration: Patients can take their medication independently.
