Ophthalmic drug bioavailability is a critical aspect of eye care, influencing how effectively medications reach the eye’s tissues. It’s not just about the drug itself but how it navigates the complex barriers of the eye to provide therapeutic effects.
Understanding these pathways is essential for developing more efficient treatments for a range of eye conditions. From glaucoma to infections, the journey of an ophthalmic drug from application to action is a fascinating blend of biology and chemistry.
Overview of Ophthalmic Drug Bioavailability
At Biotech Farm LTD, ophthalmic drug bioavailability is a cornerstone of our research and development endeavors. This process, critical for ensuring medications effectively reach the eye’s tissues, is at the forefront of our services, especially in the pre-regulatory large animal studies and the Good Laboratory Practice (GLP) validation studies stages. With our state-of-the-art facility and professional crew, we are dedicated to advancing drug and device research and development for both human and veterinary ophthalmology.
The Importance of Ophthalmic Drug Bioavailability
Ophthalmic drug bioavailability refers to the degree and rate at which a drug reaches the eye’s aqueous humor, the clear fluid in the front part of the eye, which is necessary to achieve a therapeutic effect. This is particularly challenging due to the eye’s unique anatomy and protective barriers, designed to block foreign substances. Understanding and overcoming these barriers is crucial for the development of effective treatments for eye conditions such as glaucoma, infections, and dry eye disease.
Biotech Farm LTD’s Approach
Biotech Farm LTD employs an integrated approach to study and enhance ophthalmic drug bioavailability:
- Pre-Regulatory Large Animal Studies: These studies provide essential data on how a drug behaves in a living system, which is crucial for predicting its efficacy and safety in humans. Large animal models are chosen for their anatomical and physiological similarities to the human eye, allowing for more translatable results.
- GLP Validation Studies: Ensuring compliance with GLP standards, these studies validate the methodologies used in drug development, from formulation to final product, ensuring that they meet rigorous quality and safety standards.
Founders Adir Koreh and Rinat Borenshtain-Koreh bring to the table over 30 years of experience in leading and managing research, positioning Biotech Farm LTD as a leader in the field. The facility works closely with large and small companies, both in Israel and internationally, with a commitment to benefiting mankind and animals through the development of more efficient and effective ophthalmic treatments.
Importance of Drug Delivery to Eye Tissues
For any ophthalmic medication to be effective, its bioavailability—the degree and rate at which a drug is absorbed into the living system and reaches the target tissue—is crucial. The eye’s protective mechanisms, designed to ward off foreign substances, pose significant challenges to drug delivery. These barriers include the corneal epithelium and the blood-retinal barrier, each designed to protect but also complicating the delivery of therapeutic agents directly to eye tissues.
Biotech Farm LTD addresses these challenges by leveraging advanced research and development in ophthalmic drug bioavailability. Their approach prioritizes the creation of formulations and delivery systems that can navigate the eye’s barriers efficiently. This commitment to enhancing ophthalmic drug delivery underscores the importance of targeting drugs precisely where they’re needed most, ensuring patients receive the full therapeutic benefits.
Understanding that successful treatment of eye diseases relies not just on drug potency but also on effective delivery, Biotech Farm collaborates closely with industry partners to tackle the complexities of ophthalmic bioavailability. Their state-of-the-art facilities and expert team, led by Adir Koreh and Rinat Borenshtain-Koreh, provide a comprehensive service aimed at enhancing the effectiveness of eye medications.

This comprehensive approach enables the precise assessment of how well drugs penetrate and persist in ocular tissues, laying the groundwork for successful human applications.
Focusing on the needs of both the Israeli BioMed and international Biotech industries, Biotech Farm LTD’s dedication to advancing drug and device research highlights its significance in the development of treatments that can offer real hope to patients with eye diseases. Their efforts not only enhance ophthalmic drug bioavailability but also flag the way forward for innovations in eye care, benefiting humans and animals alike.
Barriers to Ophthalmic Drug Absorption
The eye is a fortressed organ, protected by numerous barriers designed to shield it from foreign substances, including medications. Ophthalmic drug bioavailability is significantly influenced by these protective barriers, impacting the effectiveness of treatments for eye conditions.
The Corneal Barrier
The cornea, acting as the eye’s frontline defense, presents a considerable obstacle for drug absorption. It is composed of three layers:
- The epithelium
- The stroma
- The endothelium
Each layer has unique properties that affect drug penetration. The epithelium is lipophilic, slowing down the absorption of hydrophilic substances, while the stroma is hydrophilic, impeding lipophilic drug penetration. This selectivity significantly reduces the bioavailability of ophthalmic drugs, necessitating innovative solutions for effective drug delivery.
The Conjunctival Barrier
Beyond the cornea, the conjunctiva provides an alternative pathway for ophthalmic drug absorption. But, its relatively smaller surface area and the presence of conjunctival and episcleral blood flow result in rapid drug clearance, further challenging drug bioavailability.
The Blood-Retinal Barrier
For drugs targeting the posterior segment of the eye, the blood-retinal barrier stands as a formidable hurdle. Comprising the retinal pigment epithelium and the endothelial cells of the retinal vessels, it meticulously controls the substances that can enter the retinal tissue. This tight regulation secures the retina from potential toxins but also severely limits the therapeutic options for retinal diseases.
Biotech Farm LTD recognizes these barriers as critical challenges to ophthalmic drug bioavailability. With a state-of-the-art facility and a dedicated professional crew, Biotech Farm LTD is pushing the boundaries of research and development to devise formulations and delivery systems that overcome these obstacles. By focusing on pre-regulatory large animal studies and GLP validation studies, the company aims to enhance the delivery and efficacy of ophthalmic drugs.
Strategies to Enhance Ophthalmic Drug Bioavailability
The quest for improved ophthalmic drug bioavailability is an ongoing challenge in medical science, primarily due to the unique anatomical and physiological barriers of the eye. Efforts to overcome these hurdles involve innovative strategies that seek to increase the efficacy and efficiency of drug delivery systems. Biotech Farm LTD, a leader in biomed and biotech R&D, is at the forefront of developing such solutions through its advanced large animal facility.
One of the primary approaches involves optimizing formulation techniques to enhance drug penetration. This includes the use of:
- Nanoparticles for improved drug absorption
- Liposomes to increase corneal permeability
- Hydrogels that prolong drug retention time in the ocular surface
Another strategy focuses on novel delivery systems which bypass traditional barriers to drug absorption. These include:
- Intravitreal injections for direct drug delivery to the retina
- Implantable devices that release medication over a prolonged period
In situ gel forming systems have also shown promise. These systems transition from a liquid to a gel upon contact with ocular fluids, enhancing drug residence time and absorption.
Biotech Farm LTD leverages its state-of-the-art facilities and the expertise of its professional crew, dedicated to the advancement of drug and device R&D.
