What 薬学研究者 do

An English description is being prepared. Japanese description:

製薬会社等の研究部門において、新しい医薬品を開発するための研究開発を行う。
 医薬品の開発では、まず探索研究(基礎研究)として、化学合成、バイオテクノロジーやゲノム情報などを活用し、薬の候補となる新規物質を作り(医薬品候補物質)、その化学構造や物理的・化学的な特性から医薬品となる可能性を調べる。この基礎研究では、コンピュータにより物質の合成シミュレーションを行ったり、実際に医薬品の合成実験をしたりもする。さらに、関係分野の動向や最新の情報を調べたり、最新技術を用いたアプローチや社外リソースを活用した研究を行うことがある。ここまでの基礎研究がおおよそ2~3年とされる。
 次に3~5年かけ、選別された医薬品候補物質について、有効性、体内動態や安全性などを検討する(非臨床試験)。また、物質自体の品質、安全性に関する試験、臨床試験や市販に向けた製剤化の検討も行う。
 その後3~7年をかけて、ヒトでの有効性や安全性の確認を行う(臨床試験:治験)。これらの結果をもとに、国の審査を受け承認されると薬として認められる(2~3年)。
 薬学研究者はこの開発過程の中で主に基礎研究及び非臨床試験に従事する。
 実際の開発ではプロジェクトリーダー(主任研究員、課長クラス)と数人の薬学研究員がチームを作り、それぞれ役割を分担して1つのプロジェクトに数年をかけて研究、開発を行う。
 薬の開発は全体で10年以上かかることは珍しいことではない。当初の候補物質(合成化合物)が臨床試験等の開発段階を経て、承認取得に至るまでの確率は低い。業界団体調べによると、2019年~2023年の5カ年累計でみて、43万1,293の合成化合物に対し、承認取得段階に移行した数は14となっている。(2019~2023年*1)。薬品として製品化されるまでには長い年月が必要であり、自分の研究成果がなかなか形にならなくても、モチベーションを維持し続けることが必要となる。

How AI is changing this job

A written analysis for this occupation is being prepared.

AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
