WebExcretion: How does the drug leave the blood (e.g. urine)? • The quicker the excretion, the shorter the half-life • Polar, hydrophilic drugs may have increased excretion in the urine Lipophilic drugs More likely to be metabolized, creating metabolites that are likely more polar, and then more easily excreted. WebNasal delivery resulted in a significantly higher rate and extent of progesterone absorption than oral, rectal, or vaginal administration. The rate and extent of mucosal absorption decreased as penetrant hydrophilicity increased for the nasal, rectal, and vaginal routes. The results of this investigation indicate that the absorption ...

Webby drug solubility in tears and ocular surface permeability. Conjunctival and scleral tissues have similar permeability to hydrophilic drugs, while cornea is 15–25 times less permeable [7]. Bioavailability in ophthalmology refers to the amount of drug entering the aqueous humor. The drug is WebThe intravenous route is known to be the fastest way to deliver drugs into the human body and hydrophilic drugs reach 100% of bioavailability. On the other hand, there is a higher risk of infection, self-administration is not simple, and lipophilic drugs cannot be administered [112]. charles horman find a grave
