Guru Besar UGM Beri Tanggapan Soal Penggunaan Obat Sirup yang Diduga Picu Gagal Ginjal

BALIPORTALNEWS.COM, YOGYAKARTA - Kasus gagal ginjal akut diketahui menimpa ratusan anak di Indonesia dalam beberapa waktu terakhir. Kementerian Kesehatan RI pun mengimbau penyetopan segala obat berbentuk cair atau sirup menyusul adanya laporan pasien anak dengan gangguan gagal ginjal akut terdeteksi terpapar tiga zat kimia berbahaya yakni ethylene glycol (EG), diethylene glycol (DEG), dan ethylene glycol butyl ether (EGBE). Menanggapi hal itu, Pakar Farmakologi dan Farmasi Klinik UGM, Prof. Apt. Zullies Ikawati, Ph.D., menegaskan bahwa penyebab gagal ginjal akut pada anak yang terjadi di tanah air masih menjadi sebuah misteri. Menurutnya, belum bisa dipastikan ada tidaknya keterkaitan antara gagal ginjal akut dengan konsumsi obat berbentuk sirup, terutama yang mengandung parasetamol. “Ini masih jadi misteri. Kejadian gagal ginjal akut kok baru ada belakangan ini, padahal penggunaan sirup obat parasetamol sudah cukup lama dan aman digunakan,” katanya saat dihubungi Jum’at (21/10/2022). BPOM mengungkapkan ada lima obat sirup yang dinyatakan mengandung cemaran EG dan DEG diatas batas aman. Kendati Begitu, Zullies mengatakan hingga saat ini semua masih dalam proses penyelidikan untuk memastikan hubungan antara gagal ginjal akut dengan senyawa tersebut dalam kandungan obat. Ia menjelaskan EG dan DEG merupakan satu cemaran yang bisa dijumpai pada bahan baku pelarut pada obat sirup. Pada obat parasetamol dan banyak obat lainnya yang sukar larut air diperlukan bahan tambahan untuk kelarutan, biasanya di Indonesia digunakan propilen glikol atau gliserin. Bahan baku propilen glikol atau gliserin ini dimungkinan mengandung cemaran zat tersebut. “Sebenarnya ini wajar, selama masih dalam ambang batas maka tidak berisiko efek toksik termasuk gagal ginjal akut,” jelas Guru Besar Fakultas Farmasi UGM ini. Zullies menyampaikan ada berbagai faktor penyebab gagal ginjal akut. Misalnya, adanya infeksi tertentu seperti leptospirosis yang salah satunya bisa menyerang ginjal. Selain itu, infeksi bakteri E. coli juga dapat menyebabkan gagal ginjal akut. Kajian sementara dari Kemenkes menyebutkan bahwa penapisan terhadap virus dan bakteri telah dilakukan dan belum terbukti kuat sebagai penyebab gagal ginjal akut. Lantas apa yang harus dilakukan masyarakat khususnya orang tua menyikapi fenomena ini? Zullies mengimbau masyarakat untuk tetap tenang dan tidak panik. Untuk saat ini masyarakat disarankan sementara waktu ini mengikuti saran dari lembaga resmi pemerintah seperti Kemenkes, BPOM, asosiasi dokter dan lainnya untuk menghindari konsumsi obat bentuk sirup hingga diperoleh hasil yang lebih pasti. Apabila anak-anak mengalami sakit demam, batuk, maupun pilek sebaiknya mengkonsumsi obat parasetamol dalam bentuk puyer, kapsul, tablet, suppositoria atau bentuk lainnya. Untuk mengurangi rasa pahit bisa ditambahkan pemanis yang aman bagi anak. Tak kalah penting untuk selalu mengkonsultasikan efek penggunaan obat sirup dengan dokter maupun apoteker. “Untuk parasetamol yang sifatnya mengurangi gejala, mungkin penggunaan sirup lebih berisiko ketimbang manfaatnya saat ini, dimana sedang diteliti kemungkinan adanya cemaran bahan yang bisa membahayakan. Untuk itu bisa dicoba dalam bentuk puyer atau bentuk lainnya,” paparnya. Zullies menyebutkan imbauan untuk tidak menggunakan obat dalam bentuk sirup untuk semua pengobatan menjadi keputusan yang sangat dilematis. Sebab, obat dalam bentuk sirup banyak digunakan untuk anak-anak yang belum bisa menelan obat bentuk tablet atau kapsul. Selain itu, penghentian penggunaan obat sirup ini akan berdampak bagi anak-anak penderita penyakit kronis yang harus minum obat rutin berbentuk sirup dimana dalam penggunaannya selama ini tidak menimbulkan efek samping membahayakan. Misalnya, anak dengan epilepsi yang harus minum obat rutin, maka ketika obatnya dihentikan atau diubah bentuknya bisa saja menjadikan kejangnya tidak terkontrol. “Mestinya ini diatur dengan bijaksana dengan tetap mempertimbangkan risiko dan manfaat. Memang saat ini risiko terjadinya gagal ginjal akut sepertinya dianggap lebih besar dengan penggunaan sirup sehingga disarankan penghentiannya, tetapi harusnya tidak digebyah uyah (disamaratakan) ya,” paparnya.(bpn) Read the full article

Amino Silanes

Amino Functional Silanes, Diamino Silanes, Triamino Silanes, Amino Silane Oligomers, Amino Silane Hydrolysates, Amino Silane Coupling Agents, Silane Adhesion Promoters

 SiSiB is worldwide leading manufacturer of organosilanes for over 30 years. SiSiB® PC1100, chemical name 3-Aminopropyltriethoxysilane, CAS No.919-30-2, is the first and still widely used amino silane. SiSiB® PC1100  was developed in 1989.

 SiSiB amino silane is a bifunctional organosilane possessing reactive amino group and hydrolyzable inorganic alkoxysilyl groups. The dual nature of its reactivity allows it to bind chemically to both inorganic materials and organic polymers, thus functioning as an adhesion promoter, surface modifier and as a reactant for product modification.

 Except for mono-amino silanes, SiSiB offers a wide range of di-amino silanes, tri-amino silanes, piperazinyl silanes, cyclohexyamino silanes, dimethyamino silanes, diethylamino silanes and butylamino silanes.

 SiSiB amino silane can be used as adhesion promoter, coupling agent, surface modifiers, and resin additive. It can improve chemical bonding of resins to inorganic fillers and reinforcing materials.

 SiSiB amino silane can be used for epoxies, phenolics, melamines, nylons, PVC, acrylics, polyolefins, polyurethanes, and nitrile rubbers. It can be used for surface pretreatment of fillers and reinforcers.

 SiSiB aminofunctional silane also can be used as traditional amine curing agents (hardeners) for epoxy and urethane functional resins, the silanol portion of the silane reacts with each other to form siloxane bonds (Si-O-Si). The more reactive the Si-alkoxy groups are, the faster they hydrolyze and condense after the coating is applied and curing begins. Used as curing agents, silane can make curing effective at low temperature; can improve chemical resistance, UV resistance and corrosion resistance, can increase hardness and stain resistance without imparting adhesion.

 SiSiB is the earliest alpha amino silane coupling agent manufacturer in China, and now is the only commercialized manufacturer in China. SiSiB alpha silanes include, SiSiB® PC1710 - (N-phenylamino)methyltrimethoxysilane, SiSiB® PC1711 - (N-phenylamino)methyltriethoxysilane and SiSiB® PC1800 - Diethylaminomethyltriethoxysilane. The organic functional group in alpha silane is closer to the silicone atom compared with traditional gamma silane coupling agent. The close proximity of the nitrogen atom to the silicon atom can accelerate hydrolysis reaction compared to (amino-propyl) silanes.

 SiSiB® AP1160 is water-borne amino silane adhesion promoter without volatile organic components. It can be simply diluted with distilled water. These benefits are particularly useful for manufacturers seeking to reduce emissions from their water-borne products and processes.

 Care Instruction during the Silane Uses

 Silane coupling agents are subject to hydrolysis when in contact with water. Hydrolysis of a Silane Coupling Agent is accompanied by the formation of hydrogen chloride, methyl alcohol, ethyl alcohol, aklyl ethers of ethyleneglycol and other hydrolysis products so that carefulness is essential in handling and using silane coupling agents.

 · Silane coupling agents must be kept away from fire and moisture and should not be kept standing in an open condition as far as possible.

· Work rooms for handling silane coupling agents should be well ventilated. Avoid inhalation of the vapor and contact with the vapor.

· Skin and eyes must be protected from silane coupling agents by use of protective glove and eyeglasses. If silane coupling agents get on the skin or in the eye immediately wash in running water. Subsequent consultation with a doctor is recommended.

· Care should be taken not to put a Silane Coupling Agent on clothes. Clothes which come in contact with silane coupling agents should be immediately washed in running water.

· Workers are recommended to thoroughly wash their hands after handling a Silane Coupling Agent, particularly, before eating, drinking or smoking.

· Split Silane Coupling Agent must be removed by washing away with a large volume of water or absorbed by rags or sand followed by disposal by burning.

[cancerbiophd]

Out of curiosity, are there any cancer drugs that are activated at low pH? Since you mentioned that solid tumors often exist in slightly acidic environments, it seems that something like that could potentially avoid the issue of damaging too many normal cells... Though I suppose they would have to be injectable to avoid the whole stomach acid thing, which I'm guessing may pose a problem depending on the tumors' location? (though I know nothing about drug administration haha)

yup! there certainly are anti-drugs that work better in low or acidic pH’s! meaning their IC(50), or the optimal concentration to affect 50% of tumor cells, is lower at acidic pH’s, meaning a smaller dose of the drug is needed to achieve the desired effect, and lower doses are usually better, because it’s more tolerable. 

most chemotherapy agents are injected right into the bloodstream so they bypass the stomach (and liver, as much as possible, since the liver metabolizes or changes the chemical structure of drugs for the sole purpose of excreting it out). intravenous delivery also serves to spread the drug systemically, which is useful if the tumor has metastasized to distant organs. locally-injected drugs and treatments also exist.

(and you bring up a good point about how a drug is administered to avoid contact with certain organs, like the stomach. stomach acid is definitely an obstacle drug-developers encounter, and that’s why many oral drugs are encapsulated, so even if the stomach acid destroys the outside capsule, the actual drug is nice and safe. it’s interesting to think about all the natural barriers of the human body when it comes to drug design!)

—

Edit: oh! i just realized you’re asking if there are drugs that are only activated in low pH’s that are specific to the tumor microenvironment. i don’t know the answer off the top of my head but let me get back to you on that!

–

Edit 2: The actual answer to your question!

So i don’t think there are any drugs out in the clinic right now that take advantage of a tumor’s acidic extracellular pH to activate, but there’s definitely a lot of research in that field. one group is developing a micelle that will hold an anti-cancer drug inactive until it encounter the low pH of a tumor microenvironment. the actual micelle system uses “a poly(lactic acid)-b-PEG-b-poly(Lhistidine)(PLA-b-PEG-b-polyHis) triblock copolymer”, if you’re curious (or need something to say 3 times fast). in a pH lower than 7, the core “swells” and releases the drug trapped inside. 

another system is based on a “methyl ether poly(ethyleneglycol)-poly(-aminoester) block copolymer, in which the methyl ether poly(ethyleneglycol)(MPEG) part forms a hydrophilic shell and thepoly(-amino ester) a hydrophobic core.” MPEG? yeah don’t say that wrong…

anyway there’s actually a whole bunch of these low-pH-activating drug carriers, but from my limited lit research, they seem to be still undergoing laboratoroy tests, and haven’t gone into clinical trials yet (or maybe they have; this review is from 2009..)

hope that actually answers your question!

Empowering Engines with Glycol Antifreeze Excellence

Glycol, specifically referring to engine antifreeze or coolant antifreeze, is used in internal combustion engines to provide several crucial functions that help empower the engine's performance and efficiency. For several decades, this automotive antifreeze gained popularity as a “Glycol antifreeze coolant” in the automotive industry as well as food and other manufacturing industries. There are different types of Glycol-based engine coolant, primarily categorized as either Ethylene glycol or Propylene glycol-based.

Here's how Glycol antifreeze empowers Engines

Temperature Regulation: Engines produce a significant amount of heat during operation and act as a heat transfer fluid. Glycol-based coolant helps regulate the engine's temperature by absorbing excess heat and dissipating it through the radiator. This prevents the engine from overheating, which can lead to mechanical damage and reduced efficiency.

Freeze Protection: Glycol antifreeze or frost protection fluid has a lower freezing point than water. This prevents the coolant from freezing in cold temperatures, which could otherwise damage the engine block and other components. By preventing freezing, glycol helps ensure the engine can start and operate even in chilly conditions.

 Boil Protection: On the other end of the temperature spectrum, glycol also raises the boiling point of the coolant mixture. This prevents the coolant from boiling and turning into vapor in high-temperature conditions, such as during extended periods of heavy load or hot weather. Maintaining the coolant's liquid state prevents air pockets from forming in the cooling system and ensures efficient heat transfer.

Corrosion and Cavitation Protection: Glycol-based coolants often contain additives that help protect the engine's metal components from corrosion and cavitation. Corrosion can lead to deterioration of engine parts, while cavitation occurs when air bubbles form and collapse within the coolant, causing localized damage to the metal surfaces. Corrosion inhibitors or Glycol inhibitors are added to engine coolant (antifreeze) to protect the cooling system and engine components from corrosion, scale buildup, and other forms of damage.

Lubrication and Pump Efficiency: The presence of glycol in the coolant can provide a level of lubrication for the water pump and other components in the cooling system. This helps reduce friction and wear, contributing to the overall efficiency and longevity of the engine.

 Consistent Engine Performance: By maintaining a stable operating temperature range, glycol-based coolant ensures that the engine operates efficiently and consistently. This consistency in performance results in better fuel combustion, reduced emissions, and overall better engine efficiency.

It's important to note that while glycol-based coolant offers these advantages, it's essential to maintain the proper coolant-to-water ratio as specified by the vehicle manufacturer. Using too much or too little glycol can affect the coolant's ability to perform these functions effectively. Regular maintenance, including coolant flushes and replacement, is also necessary to keep the coolant's properties optimal.

Chemtex Speciality Limited is an eminent supplier of glycol coolants, radiator fluid as well as antifreeze additives and Extended Life Coolant. Chemtex’s specially designed industrial Glycol provides an extended service life compared to traditional coolants, as it typically uses advanced organic acid technology (OAT) or hybrid organic acid technology (HOAT) formulations to offer enhanced protection and longevity for modern engines.
