Yes the oral route for drug administration is the safest route.
Topical administration is not a gastrointestinal tract route of drug administration. It involves applying medication directly to the skin or mucous membranes for localized effects.
Skin based absorbtion, if it's even possible with that drug, or oral injestion.

The route of administration of a drug can affect its bioavailability by influencing factors such as first-pass metabolism, absorption rate, and drug stability. For example, intravenous administration bypasses the first-pass metabolism, leading to higher bioavailability compared to oral administration where the drug may be metabolized before reaching the systemic circulation. Additionally, different routes can also affect the onset of action and duration of drug effects.
The process that brings a drug from the administration site into the bloodstream is called absorption. It refers to the movement of a drug from its site of administration into the bloodstream for distribution throughout the body. Factors such as route of administration, drug formulation, and physiological properties can affect drug absorption.
Intravenous is a route of administration where the drug or substance is injected directly into the veins.
No. That is not a good route of administration of drug during the menstruation. The drug will be washed away in normal course. Your doctor is the best judge.
Injecting the drug intravenously or smoking it can produce the fastest effects as the drug enters the bloodstream quickly. However, these methods also pose higher risks to health and can lead to addiction or overdose. It is important to prioritize safety and consider the potential consequences of rapid drug administration.
