Levodopa is a precursor of dopamine and is used in the management of Parkinson’s disease order 10 mg alfuzosin with mastercard. A common strategy to increase brain levels of levodopa is to inhibit peripheral enzymes that either degrade levodopa or convert levodopa to dopamine in the periphery discount alfuzosin 10 mg otc. Preventing the peripheral conversion and degradation would leave more levodopa for cerebral conversion purchase 10mg alfuzosin fast delivery. The L-system is selective to amino-acid-like compounds with a bulky hydrophobic side-chain [45] buy 10 mg alfuzosin with mastercard. Various amino acid drugs such as acivicin, phosphonoformate-tyrosine conjugates, and nitrosoarginine derivatives are also carried by the L-system. There is also a risk that the more lipophilic analog or prodrug may have a higher uptake into other tissues, that is, low target selectivity. The characteristics needed to improve peptide drug bioavailability that we have previously described in Section 8. As another thermodynamic beneft of compounds with fewer rotatable bonds, there is less fexibility in the drug [14]. Because the drug was designed to make the free conformation of the inhibitor similar to its bound conformation, there is a minimal loss of conformation entropy. Of interest, cell-penetrating Tat-peptide may also be attached to the surface of either liposomes or nanoparticles [54]. This attachment appears to greatly facilitate the internalization by cells, despite the relatively complex and large structures of the colloidal particles. With the use of cell-penetrating peptides, the per- meation of the lipophilic particles may be attributed to both adsorptive-mediated and passive diffusinal transcytosis. Hence, this emulsion system exhibits combined properties of a hydrophilic nonionic network and a swollen polyelectrolyte network. Further refnement of this system could lead to a delivery of drugs and biomacromolecules to the brain. Met-enkephalin is an endoge- nous opioid analgesic (Tyr-Gly-Gly-Phe-Met) that is prone to enzyme degradation in both brain and plasma [56]. Indeed, this improved overall bioavailability outweighs the decrease in blood-to-brain transport due to structural modifcations. We have briefy mentioned the use of markers with liposomes and nanoparticles in Section 8. A murine monoclonal antibody to rat transferrin was conjugated with peptides, and it was demonstrated that the conjugation increased brain uptake of the peptides [59]. The use of a viral vector (virosome) with inherent capability of penetrating endothelial cells of brain capillaries has been demonstrated [61]. For example, inhibition of P-gp has been investigated [65] and some P-gp inhibitors were brought up in Section 8. Needless to say, this method would most likely damage brain tissues and raises the risk for infections. The olfactory epithelium is located in the upper posterior part of the human nasal cavity with its nerve cells directly projected into the olfactory bulb of the brain. Although studies have suggested that this feat is achievable [67], actual delivery of peptide drugs or any drug by this mean has yet to be fully demonstrated. Other than vasopressin, there was no increase in peripheral blood concentrations of the peptides over the observed 30-min period. The delivery of peptide-derived antibiotic cephalexin, and permeability enhancer enzyme hyaluronidase have also been achieved by intranasal application [69]. These charge issues encompass cases in which these drugs are either readily ionized, too polar or hydrophilic to cross membranes to reach the cir- culatory system. Immunization exemplifes the delivery of protein drugs that must be administered by injection. Although the parenteral route is the most direct route into the main circulatory system and the onset of action is rapid, it is also the most dangerous because it bypasses most of the body’s natural barriers and defenses, and exposes the user to health problems such as hepatitis, abscesses, infections, and insol- uble particles. As a painful and inconvenient route that requires extreme care during injection, the parenteral route is laden with compliance and adherence problems. Some problems associated with the needle-and-syringe form of injection have been partially relieved by jet injectors.
